Here, we report that both the G-protein-coupled receptor sphingosine 1-phosphate receptor 1 (S1PR1) and its ligand sphingosine 1-phosphate (S1P) are required for collective upstream migration of human lymphatic microvascular endothelial cells in an in vitro setting. These findings are consistent with a model in which signalling via S1P and S1PR1 are integral components in the response of lymphatic endothelial cells to the stimulus provided by fluid flow.},\n\tissn = {1742-5689},\n\tURL = {http://rsif.royalsocietypublishing.org/content/13/125/20160823},\n\teprint = {http://rsif.royalsocietypublishing.org/content/13/125/20160823.full.pdf},\n\tjournal = {Journal of The Royal Society Interface}\n}\n\n

@article{C5SM01603G,\n\tAbstract = {The surfactant lining the walls of the alveoli in the lungs increases pulmonary compliance and prevents collapse of the lung at the end of expiration. In premature born infants{,} surfactant deficiency causes problems{,} and lung surfactant replacements are instilled to facilitate breathing. These pulmonary surfactants{,} which form complex structured fluid-fluid interfaces{,} need to spread with great efficiency and once in the alveolus they have to form a thin stable film. In the present work{,} we investigate the mechanisms affecting the stability of surfactant-laden thin films during spreading{,} using drainage flows from a hemispherical dome. Three commercial lung surfactant replacements Survanta{,} Curosurf and Infasurf{,} along with the phospholipid dipalmitoylphosphatidylcholine (DPPC){,} are used. The surface of the dome can be covered with human alveolar epithelial cells and experiments are conducted at the physiological temperature. Drainage is slowed down due to the presence of all the different lung surfactant replacements and therefore the thin films show enhanced stability. However{,} a scaling analysis combined with visualization experiments demonstrates that different mechanisms are involved. For Curosurf and Infasurf{,} Marangoni stresses are essential to impart stability and interfacial shear rheology does not play a role{,} in agreement with what is observed for simple surfactants. Survanta{,} which was historically the first natural surfactant used{,} is rheologically active. For DPPC the dilatational properties play a role. Understanding these different modes of stabilization for natural surfactants can benefit the design of effective synthetic surfactant replacements for treating infant and adult respiratory disorders.},\n\tAuthor = {Hermans, Eline and Saad Bhamla, M. and Kao, Peter and Fuller, Gerald G. and Vermant, Jan},\n\tDate-Added = {2015-11-13 18:20:16 +0000},\n\tDate-Modified = {2015-11-13 18:20:16 +0000},\n\tDoi = {10.1039/C5SM01603G},\n\tIssue = {41},\n\tJournal = {Soft Matter},\n\tPages = {8048-8057},\n\tPublisher = {The Royal Society of Chemistry},\n\tTitle = {Lung surfactants and different contributions to thin film stability},\n\tUrl = {http://dx.doi.org/10.1039/C5SM01603G},\n\tVolume = {11},\n\tYear = {2015},\n\tBdsk-Url-1 = {http://dx.doi.org/10.1039/C5SM01603G},\n\tBdsk-File-1 = {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}}\n\n

Over a period of time, these naturally occurring lipids form interfacial coatings that modify the wettability characteristics of these foreign synthetic surfaces. In this study, we examine the deposition and consequences of tear film lipids on silicone hydrogel (SiHy) contact lenses. We use bovine meibum, which is a complex mixture of waxy esters, cholesterol esters, and lipids that is secreted from the meibomian glands located on the upper and lower eyelids of mammals. For comparison, we study two commercially available model materials: dipalmitoylphosphatidylcholine (DPPC) and cholesterol. Upon deposition, we find that DPPC and meibum remain closer to the SiHy surface than cholesterol, which diffuses further into the porous SiHy matrix. In addition, we also monitor the fate of unstable thin liquid films that consequently rupture and dewet on these lipid-decorated surfaces. This dewetting provides valuable qualitative and quantitative information about the wetting characteristics of these SiHy substrates. We observe that decorating the SiHy surface with simple model lipids such as DPPC and cholesterol increases the hydrophilicity, which consequently inhibits dewetting, whereas meibum behaves conversely.},\n\tAuthor = {Bhamla, M Saad and Nash, Walter L and Elliott, Stacey and Fuller, Gerald G},\n\tDoi = {10.1021/la503437a},\n\tJournal = {Langmuir},\n\tLanguage = {English},\n\tMonth = apr,\n\tNumber = {13},\n\tPages = {3820--3828},\n\tPmid = {25280206},\n\tTitle = {Influence of lipid coatings on surface wettability characteristics of silicone hydrogels.},\n\tUrl = {http://pubs.acs.org/doi/abs/10.1021/la503437a},\n\tVolume = {31},\n\tYear = {2015},\n\tBdsk-Url-1 = {http://pubs.acs.org/doi/abs/10.1021/la503437a},\n\tBdsk-Url-2 = {http://dx.doi.org/10.1021/la503437a}}\n\n

The non-Newtonian character of these surfaces fundamentally alters the dynamics of drainage. We show that increased film stability during drainage can occur as a consequence of enhanced surface rheology. Increasing the surfactant layer viscosity decreases the rate of drainage; however, this retarding influence is most pronounced when the insoluble surfactant layer has significant elasticity. We also present a simple theoretical model that offers qualitative support to our experimental findings.},\n\tAuthor = {Bhamla, M Saad and Giacomin, Caroline E and Balemans, Caroline and Fuller, Gerald G},\n\tDoi = {10.1039/c3sm52934g},\n\tJournal = {Soft Matter},\n\tLanguage = {English},\n\tMonth = sep,\n\tNumber = {36},\n\tPages = {6917--6925},\n\tPmid = {25140576},\n\tTitle = {Influence of interfacial rheology on drainage from curved surfaces.},\n\tUrl = {http://adsabs.harvard.edu/cgi-bin/nph-data_query?bibcode=2014SMat...10.6917B&link_type=EJOURNAL},\n\tVolume = {10},\n\tYear = {2014},\n\tBdsk-Url-1 = {http://adsabs.harvard.edu/cgi-bin/nph-data_query?bibcode=2014SMat...10.6917B&link_type=EJOURNAL},\n\tBdsk-Url-2 = {http://dx.doi.org/10.1039/c3sm52934g}}\n\n

We present an experimental analysis of rinsing flows using a high-speed camera and model fluids to decouple the effect of shear-thinning and elasticity. Varying the rheology of the coating fluid produced several types of instabilities at both the air-liquid interface and liquid-liquid interface. Layered "stepped jumps" and "crowning" on the rim of the jumps were both suppressed by fluid elasticity, while Saffman-Taylor fingering patterns showed strong dependence on both shear-thinning and normal stresses. In addition, the hydraulic jump evolution was quantitatively determined using a laser triangulation technique, and "recoil" of the jump front resulting from fluid elasticity was observed. Our work shows that the non-Newtonian two-fluid circular hydraulic jump is very complex, and the instabilities that arise also introduce additional complications when developing theoretical models. textcopyright Springer-Verlag Berlin Heidelberg 2013.},\n\tAuthor = {Hsu, Tienyi T and Walker, Travis W and Frank, Curtis W and Fuller, Gerald G},\n\tDoi = {10.1007/s00348-013-1645-9},\n\tJournal = {Experiments in Fluids},\n\tNumber = {1},\n\tPages = {1645},\n\tTitle = {Instabilities and elastic recoil of the two-fluid circular hydraulic jump},\n\tUrl = {http://link.springer.com/10.1007/s00348-013-1645-9},\n\tVolume = {55},\n\tYear = {2014},\n\tBdsk-Url-1 = {http://link.springer.com/10.1007/s00348-013-1645-9},\n\tBdsk-Url-2 = {http://dx.doi.org/10.1007/s00348-013-1645-9}}\n\n

We built an impinging flow device that exposes endothelial cells to gradients of shear stress. Using this device, we investigated the response of microvascular endothelial cells to shear-stress gradients that ranged from 0 to a peak shear stress of 9-210 dyn/cm2. We observe that at high confluency, these cells migrate against the direction of fluid flow and concentrate in the region of maximum wall shear stress, whereas low-density microvascular endothelial cells that lack cell-cell contacts migrate in the flow direction. In addition, the cells align parallel to the flow at low wall shear stresses but orient perpendicularly to the flow direction above a critical threshold in local wall shear stress. Our observations suggest that endothelial cells are exquisitely sensitive to both magnitude and spatial gradients in wall shear stress. The impinging flow device provides a, to our knowledge, novel means to study endothelial cell migration and polarization in response to gradients in physical forces such as wall shear stress. textcopyright 2014 Biophysical Society.},\n\tAuthor = {Ostrowski, Maggie A and Huang, Ngan F and Walker, Travis W and Verwijlen, Tom and Poplawski, Charlotte and Khoo, Amanda S and Cooke, John P and Fuller, Gerald G and Dunn, Alexander R},\n\tDoi = {10.1016/j.bpj.2013.11.4502},\n\tJournal = {Biophysical Journal},\n\tNumber = {2},\n\tPages = {366--374},\n\tTitle = {Microvascular {Endothelial} {Cells} {Migrate} {Upstream} and {Align} {Against} the {Shear} {Stress} {Field} {Created} by {Impinging} {Flow}},\n\tUrl = {http://linkinghub.elsevier.com/retrieve/pii/S0006349513058074},\n\tVolume = {106},\n\tYear = {2014},\n\tBdsk-Url-1 = {http://linkinghub.elsevier.com/retrieve/pii/S0006349513058074},\n\tBdsk-Url-2 = {http://dx.doi.org/10.1016/j.bpj.2013.11.4502}}\n\n

However, the effect of protein deposition on lens interactions with the corneal epithelium remains largely unexplored. The current study employs a live cell rheometer to quantify human corneal epithelial cell adhesion to soft contact lenses fouled with the tear film protein lysozyme. PureVision balafilcon A and AirOptix lotrafilcon B lenses were soaked for five days in either phosphate buffered saline (PBS), borate buffered saline (BBS), or Sensitive Eyes Plus Saline Solution (Sensitive Eyes), either pure or in the presence of lysozyme. Treated contact lenses were then contacted to a live monolayer of corneal epithelial cells for two hours, after which the contact lens was sheared laterally. The apparent cell monolayer relaxation modulus was then used to quantify the extent of cell adhesion to the contact lens surface. For both lens types, lysozyme increased corneal cell adhesion to the contact lens, with the apparent cell monolayer relaxation modulus increasing up to an order of magnitude in the presence of protein. The magnitude of this increase depended on the identity of the soaking solution: lenses soaked in borate-buffered solutions (BBS, Sensitive Eyes) exhibited a much greater increase in cell attachment upon protein addition than those soaked in PBS. Significantly, all measurements were conducted while subjecting the cells to moderate surface pressures and shear rates, similar to those experienced by corneal cells in vivo.},\n\tAuthor = {Elkins, Claire M and Qi, Qin M and Fuller, Gerald G},\n\tDoi = {10.1371/journal.pone.0105512},\n\tJournal = {PLoS ONE},\n\tLanguage = {English},\n\tNumber = {8},\n\tPages = {e105512},\n\tPmid = {25144576},\n\tTitle = {Corneal {Cell} {Adhesion} to {Contact} {Lens} {Hydrogel} {Materials} {Enhanced} via {Tear} {Film} {Protein} {Deposition}.},\n\tUrl = {http://eutils.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&id=25144576&retmode=ref&cmd=prlinks},\n\tVolume = {9},\n\tYear = {2014},\n\tBdsk-Url-1 = {http://eutils.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&id=25144576&retmode=ref&cmd=prlinks},\n\tBdsk-Url-2 = {http://dx.doi.org/10.1371/journal.pone.0105512}}\n\n

@article{hollenbeck_molecular_2014,\n\tAbstract = {Biofilm formation increases both the survival and infectivity of Vibrio cholerae, the causative agent of cholera. V. cholerae is capable of forming biofilms on solid surfaces and at the air-liquid interface, termed pellicles. Known components of the extracellular matrix include the matrix proteins Bap1, RbmA, and RbmC, an exopolysaccharide termed Vibrio polysaccharide, and DNA. In this work, we examined a rugose strain of V. cholerae and its mutants unable to produce matrix proteins by interfacial rheology to compare the evolution of pellicle elasticity in real time to understand the molecular basis of matrix protein contributions to pellicle integrity and elasticity. Together with electron micrographs, visual inspection, and contact angle measurements of the pellicles, we defined distinct contributions of the matrix proteins to pellicle morphology, microscale architecture, and mechanical properties. Furthermore, we discovered that Bap1 is uniquely required for the maintenance of the mechanical strength of the pellicle over time and contributes to the hydrophobicity of the pellicle. Thus, Bap1 presents an important matrix component to target in the prevention and dispersal of V. cholerae biofilms.},\n\tAuthor = {Hollenbeck, Emily C and Fong, Jiunn CN and Lim, Ji Youn and Yildiz, Fitnat H and Fuller, Gerald G and Cegelski, Lynette},\n\tDoi = {10.1016/j.bpj.2014.10.015},\n\tJournal = {Biophysical Journal},\n\tLanguage = {English},\n\tMonth = nov,\n\tNumber = {10},\n\tPages = {2245--2252},\n\tTitle = {Molecular {Determinants} of {Mechanical} {Properties} of {V}. cholerae {Biofilms} at the {Air}-{Liquid} {Interface}},\n\tUrl = {http://linkinghub.elsevier.com/retrieve/pii/S0006349514010662},\n\tVolume = {107},\n\tYear = {2014},\n\tBdsk-Url-1 = {http://linkinghub.elsevier.com/retrieve/pii/S0006349514010662},\n\tBdsk-Url-2 = {http://dx.doi.org/10.1016/j.bpj.2014.10.015}}\n\n

The changes in the tacticities of the polymers are modest. However, the tacticity affects the phase separation process but in a different way in two studied cases, at pH 8 and 9. The pH, and thus the charge of the polymer, affects the balance between electrostatic and stereochemical effects. Upon the chain collapse, the zeta potential of the polymer decreases discontinuously at pH 9, whereas at pH 8 the potential keeps almost constant. However, even in the latter case the influence of the isotactic segments on the thermal transition may be observed. Increasing isotacticity is suggested to decrease the flexibility of the polymer chain. It also causes the polymers to adsorb in a more organized manner to the air/water interface than the atactic ones do.

At Tween 20 concentrations near and above the critical micelle concentration, the interfacial viscoelastic modulus is reduced to zero as cellular aggregates at the air-liquid interface are locally disconnected and eventually eliminated. Tween 20 does not inhibit the production of curli but prevents curli-integrated film formation.

However, the effects of spatial patterning on the function and global transcriptome of ECs are incompletely characterized. We used both parallel-aligned micropatterned and nanopatterned biomaterials to evaluate the effects of spatial patterning on the phenotype of ECs, based on gene expression profiling, functional characterization of monocyte adhesion, and quantification of cellular morphology. We demonstrate that both micropatterned and aligned nanofibrillar biomaterials could effectively guide EC organization along the direction of the micropatterned channels or nanofibrils, respectively. The ability of ECs to sense spatial patterning cues were abrogated in the presence of cytoskeletal disruption agents. Moreover, both micropatterned and aligned nanofibrillar substrates promoted an athero-resistant EC phenotype by reducing endothelial adhesiveness for monocytes and platelets, as well as by downregulating the expression of adhesion proteins and chemokines. We further found that micropatterned ECs have a transcriptional signature that is unique from non-patterned ECs, as well as from ECs aligned by shear stress. These findings highlight the importance of spatial patterning cues in guiding EC organization and function, which may have clinical relevance in the development of vascular grafts that promote patency. textcopyright 2013 Elsevier Ltd.},\n\tAuthor = {Huang, N F and Lai, E S and Ribeiro, A J S and Pan, S and Pruitt, B L and Fuller, G.G. and Cooke, J P},\n\tJournal = {Biomaterials},\n\tNumber = {12},\n\tPages = {2928--2937},\n\tTitle = {Spatial patterning of endothelium modulates cell morphology, adhesiveness and transcriptional signature},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-84873473274&partnerID=40&md5=e880594361501a8198ff447671e6b254},\n\tVolume = {34},\n\tYear = {2013},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-84873473274&partnerID=40&md5=e880594361501a8198ff447671e6b254}}\n\n

This is a key piece of evidence supporting the hypothesis that the anesthetic actions of BHB are due to the metabolite's abilities to alter physical properties of cell membranes, leading to indirect effects on membrane protein function. Pressure--area isotherms show that BHB changes the compressibility of the monolayer and decrease the size of the two-phase coexistence region.

The unaligned ECs in disturbed flow fields manifest altered function and reduced survival that promote lesion formation. We demonstrate that the alignment of the ECs may directly influence their biology, independent of fluid flow. We developed aligned nanofibrillar collagen scaffolds that mimic the structure of collagen bundles in blood vessels, and examined the effects of these materials on EC alignment, function, and in vivo survival. ECs cultured on 30-nm diameter aligned fibrils re-organized their F-actin along the nanofibril direction, and were 50\\% less adhesive for monocytes than the ECs grown on randomly oriented fibrils. After EC transplantation into both subcutaneous tissue and the ischemic hindlimb, EC viability was enhanced when ECs were cultured and implanted on aligned nanofibrillar scaffolds, in contrast to non-patterned scaffolds. ECs derived from human induced pluripotent stem cells and cultured on aligned scaffolds also persisted for over 28 days, as assessed by bioluminescence imaging, when implanted in ischemic tissue. By contrast, ECs implanted on scaffolds without nanopatterning generated no detectable bioluminescent signal by day 4 in either normal or ischemic tissues. We demonstrate that 30-nm aligned nanofibrillar collagen scaffolds guide cellular organization, modulate endothelial inflammatory response, and enhance cell survival after implantation in normal and ischemic tissues. textcopyright 2013.},\n\tAuthor = {Huang, Ngan F and Okogbaa, Janet and Lee, Jerry C and Jha, Arshi and Zaitseva, Tatiana S and Paukshto, Michael V and Sun, John S and Punjya, Niraj and Fuller, Gerald G and Cooke, John P},\n\tDoi = {10.1016/j.biomaterials.2013.02.036},\n\tJournal = {Biomaterials},\n\tMonth = may,\n\tNumber = {16},\n\tPages = {4038--4047},\n\tPmid = {23480958},\n\tTitle = {The modulation of endothelial cell morphology, function, and survival using anisotropic nanofibrillar collagen scaffolds},\n\tUrl = {http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=3695739&tool=pmcentrez&rendertype=abstract http://linkinghub.elsevier.com/retrieve/pii/S0142961213002196},\n\tVolume = {34},\n\tYear = {2013},\n\tBdsk-Url-1 = {http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=3695739&tool=pmcentrez&rendertype=abstract%20http://linkinghub.elsevier.com/retrieve/pii/S0142961213002196},\n\tBdsk-Url-2 = {http://dx.doi.org/10.1016/j.biomaterials.2013.02.036}}\n\n

@article{leiske_temperature-induced_2012,\n\tAbstract = {Meibomian lipids are the primary component of the lipid layer of the tear film. Composed primarily of a mixture of lipids, meibum exhibits a range of melt temperatures. Compositional changes that occur with disease may alter the temperature at which meibum melts. Here we explore how the mechanical properties and structure of meibum from healthy subjects depend on temperature. Interfacial films of meibum were highly viscoelastic at 17textdegreeC, but as the films were heated to 30textdegreeC the surface moduli decreased by more than two orders of magnitude. Brewster angle microscopy revealed the presence of micron-scale inhomogeneities in meibum films at higher temperatures. Crystalline structure was probed by small angle x-ray scattering of bulk meibum, which showed evidence of a majority crystalline structure in all samples with lamellar spacing of 49 that melted at 34textdegreeC. A minority structure was observed in some samples with d-spacing at 110 that persisted up to 40textdegreeC. The melting of crystalline phases accompanied by a reduction in interfacial viscosity and elasticity has implications in meibum behavior in the tear film. If the melt temperature of meibum was altered significantly from disease-induced compositional changes, the resultant change in viscosity could alter secretion of lipids from meibomian glands, or tear-film stabilization properties of the lipid layer. textcopyright 2012 Biophysical Society.},\n\tAuthor = {Leiske, Danielle L and Leiske, Christopher I and Leiske, Daniel R and Toney, Michael F and Senchyna, Michelle and Ketelson, Howard A and Meadows, David L and Fuller, Gerald G},\n\tDoi = {10.1016/j.bpj.2011.12.017},\n\tJournal = {Biophysical Journal},\n\tNumber = {2},\n\tPages = {369--376},\n\tTitle = {Temperature-{Induced} {Transitions} in the {Structure} and {Interfacial} {Rheology} of {Human} {Meibum}},\n\tUrl = {http://linkinghub.elsevier.com/retrieve/pii/S0006349511054191},\n\tVolume = {102},\n\tYear = {2012},\n\tBdsk-Url-1 = {http://linkinghub.elsevier.com/retrieve/pii/S0006349511054191},\n\tBdsk-Url-2 = {http://dx.doi.org/10.1016/j.bpj.2011.12.017}}\n\n

New approaches and quantitative data are needed to elucidate the composition and architecture of biofilms, and such data need to be correlated with mechanical and physicochemical properties that relate to function. We performed a panel of interfacial rheological measurements during biofilm formation at the air-liquid interface by the Escherichia coli strain UTI89, which is noted for its importance in studies of urinary tract infection and for its assembly of functional amyloid fibers termed curli. Brewster-angle microscopy and measurements of the surface elasticity (Gstextasciiacute) and stress-strain response provided sensitive and quantitative parameters that revealed distinct stages during bacterial colonization, aggregation, and eventual formation of a pellicle at the air-liquid interface. Pellicles that formed under conditions that upregulate curli production exhibited an increase in strength and viscoelastic properties as well as a greater ability to recover from stress-strain perturbation. The results suggest that curli, as hydrophobic extracellular amyloid fibers, enhance the strength, viscoelasticity, and resistance to strain of E. coli biofilms formed at the air-liquid interface. textcopyright 2012 by the Biophysical Society.},\n\tAuthor = {Wu, C and Lim, J Y and Fuller, G.G. and Cegelski, L},\n\tJournal = {Biophysical Journal},\n\tNumber = {3},\n\tPages = {464--471},\n\tTitle = {Quantitative analysis of amyloid-integrated biofilms formed by uropathogenic escherichia coli at the air-liquid interface},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-84864717953&partnerID=40&md5=1e4286733a4716dd24fcd0f1820030d4},\n\tVolume = {103},\n\tYear = {2012},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-84864717953&partnerID=40&md5=1e4286733a4716dd24fcd0f1820030d4}}\n\n

Despite its great success, there are patients in which benefit from these devices is rather limited. One reason may be a poor neuron-device interaction, where the electric fields generated by the electrode array excite a wide range of tonotopically organized spiral ganglion neurons at the cost of spatial resolution. Coating of CI electrodes to provide a welcoming environment combined with suitable surface chemistry (e.g. with neurotrophic factors) has been suggested to create a closer bioelectrical interface between the electrode array and the target tissue, which might lead to better spatial resolution, better frequency discrimination, and ultimately may improve speech perception in patients. Here we investigate the use of a collagen surface with a cholesteric banding structure, whose orientation can be systemically controlled as a guiding structure for neurite outgrowth. We demonstrate that spiral ganglion neurons survive on collagen-coated surfaces and display a directed neurite growth influenced by the direction of collagen fibril deposition. The majority of neurites grow parallel to the orientation direction of the collagen. We suggest collagen coating as a possible future option in CI technology to direct neurite outgrowth and improve hearing results for affected patients.},\n\tAuthor = {Volkenstein, Stefan and Kirkwood, John E and Lai, Edwina and Dazert, Stefan and Fuller, Gerald G and Heller, Stefan},\n\tDoi = {10.1007/s00405-011-1775-8},\n\tJournal = {European archives of oto-rhino-laryngology : official journal of the European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino-Laryngology - Head and Neck Surgery},\n\tLanguage = {English},\n\tMonth = apr,\n\tNumber = {4},\n\tPages = {1111--1116},\n\tPmid = {21952794},\n\tTitle = {Oriented collagen as a potential cochlear implant electrode surface coating to achieve directed neurite outgrowth.},\n\tUrl = {http://link.springer.com/10.1007/s00405-011-1775-8},\n\tVolume = {269},\n\tYear = {2012},\n\tBdsk-Url-1 = {http://link.springer.com/10.1007/s00405-011-1775-8},\n\tBdsk-Url-2 = {http://dx.doi.org/10.1007/s00405-011-1775-8}}\n\n

@article{rosenfeld_consequences_2012,\n\tAbstract = {The phenomenon of dewetting is frequently observed in our everyday life. It is of central importance in many technological applications as well as in a variety of physical and biological systems. The presence of nonsoluble surfactants at an air/liquid interface may affect the dewetting properties of the aqueous layer. An important example is the tear film, which comprises an aqueous layer covered with a ∼100-nm-thick blanket of lipids, known as the meibomian lipids. Interfacial rheological measurements of meibomian lipids reveal that these films are remarkably viscoelastic. Tear film dewetting is of central importance to understanding tear film stability. To better understand the role of surface viscoelasticity in tear film stability, we have developed a methodology to systematically control interfacial rheology of thin aqueous layers at the onset of dewetting events. The apparatus allows control over the surface pressure of the monolayer, which is a key feature since this variable controls the surface viscoelasticity. Three insoluble monolayer materials were used: newtonian arachidyl alcohol (AA), DPPC, a phospholipid that is slightly viscoelastic, and meibum, which produces a strongly viscoelastic monolayer. It is reported that monolayers of viscoelastic surfactants are able to stabilize thin films against spontaneous dewetting. As the surface pressure of these layers is increased, their effectiveness is enhanced. Moreover, these surfactants are able to reduce the critical film thickness for dewetting. Meibum is particularly effective in stabilizing thin films. Our results suggest that the meibomian lipids play a vital role in maintaining tear film stability in addition to suppressing evaporation.},\n\tAuthor = {Rosenfeld, Liat and Fuller, Gerald G},\n\tDoi = {10.1021/la302731z},\n\tJournal = {Langmuir},\n\tLanguage = {English},\n\tMonth = oct,\n\tNumber = {40},\n\tPages = {14238--14244},\n\tPmid = {22989061},\n\tTitle = {Consequences of interfacial viscoelasticity on thin film stability.},\n\tUrl = {http://pubs.acs.org/doi/abs/10.1021/la302731z},\n\tVolume = {28},\n\tYear = {2012},\n\tBdsk-Url-1 = {http://pubs.acs.org/doi/abs/10.1021/la302731z},\n\tBdsk-Url-2 = {http://dx.doi.org/10.1021/la302731z}}\n\n

Our procedure is based on flowing feed solution, containing both inorganic cations and polymeric molecules, through a nanoporous membrane into a receiver solution with anions, which leads to the formation of mineralized nanofibers at the exit of the pores. With this strategy, we were able to achieve size control of the nanofiber diameters. We illustrate this approach by producing collagen fibrils with calcium phosphate incorporated inside the fibrils. This structure, which resembles the basic constituent of bones, assembles itself without the addition of noncollagenous proteins or their polymeric substitutes. Rheological experiments demonstrated that the stiffness of gels derived from these fibrils is enhanced by mineralization. Growth experiments of human adipose derived stem cells on these gels showed the compatibility of the fibrils in a tissue-regeneration context. textcopyright 2011 American Chemical Society.},\n\tAuthor = {Maas, M and Guo, P and Keeney, M and Yang, F and Hsu, T M and Fuller, G.G. and Martin, C R and Zare, R N},\n\tJournal = {Nano Letters},\n\tNumber = {3},\n\tPages = {1383--1388},\n\tTitle = {Preparation of mineralized nanofibers: {Collagen} fibrils containing calcium phosphate},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-79952600465&partnerID=40&md5=707c391e32e7a8f2f48ea7a9ce6a6a9b},\n\tVolume = {11},\n\tYear = {2011},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-79952600465&partnerID=40&md5=707c391e32e7a8f2f48ea7a9ce6a6a9b}}\n\n

Most anastomoses are performed with sutures, which are technically challenging and can lead to failure from intimal hyperplasia and foreign body reaction. Numerous alternatives to sutures have been proposed, but none has proven superior, particularly in small or atherosclerotic vessels. We have developed a new method of sutureless and atraumatic vascular anastomosis that uses US Food and Drug Administration (FDA)-approved thermoreversible tri-block polymers to temporarily maintain an open lumen for precise approximation with commercially available glues. We performed end-to-end anastomoses five times more rapidly than we performed hand-sewn controls, and vessels that were too small ({\\textless}1.0 mm) to sew were successfully reconstructed with this sutureless approach. Imaging of reconstructed rat aorta confirmed equivalent patency, flow and burst strength, and histological analysis demonstrated decreased inflammation and fibrosis at up to 2 years after the procedure. This new technology has potential for improving efficiency and outcomes in the surgical treatment of cardiovascular disease. textcopyright 2011 Nature America, Inc.

In this article we introduce a novel, straightforward flow processing technique that fabricates a small diameter tubular matrix constructed of anisotropic collagen fibrils. Scanning electron microscopy confirmed the uniform alignment of the collagen fibrils and subsequent matrix-induced alignment of human fibroblasts. The uniform alignment of the fibroblasts along the collagen fibrils demonstrated the ability of the aligned fibrils to successfully dictate the directional growth of human fibroblasts through contact guidance. Various non-cytotoxic cross-linking techniques were also applied to the collagen conduit to enhance the mechanical properties. Tensile testing and burst pressure were the two measurements performed to characterize the mechanical integrity of the conduit. Mechanical characterization of the cross-linked collagen conduits identified 1-ethyl-3-(3-dimethyl aminopropyl) carbodiimide hydrochloride cross-linking as the most promising technique to reinforce the mechanical properties of native collagen. An oriented conduit of biocompatible material has been fabricated with decent mechanical strength and at a small diameter scale, which is especially applicable in engineering cardiovascular tissues and nerve grafts. textcopyright 2011 Acta Materialia Inc.

@article{hsu_role_2011,\n\tAbstract = {Rinsing flows are common processes where a jet of one liquid impinges upon a layer of a second liquid for the purpose of removing the second liquid. An imaging setup has been developed to obtain both qualitative and quantitative data on the rinsing flow of a jet of water impinging on either layers of Newtonian or elastic fluids. Three classes of test fluids have been investigated: a Newtonian glycerol-water solution, a semidilute aqueous solution of high molecular weight polyacrylamide solution displaying both elasticity and shear thinning, and an elastic but non-shear thinning Boger fluid. The fluids were designed to have approximately equal zero-shear viscosities. For all cases, a circular hydraulic jump occurs and Saffman-Taylor instabilities were observed at the interface between the low viscosity jet and the higher viscosity coating liquids. Results show that the elasticity (extensional viscosity) of the samples influences the pattern of the instabilities and contributes to dampening surface disturbances in the vicinity of the hydraulic jump. Quantitative measurements of liquid layer thicknesses were obtained using a laser triangulation technique. We observed that shear thinning contributes to increasing the velocity of the hydraulic jump circle growth, and the growth profile appears to be linear instead of logarithmic-like as in the Newtonian fluids. Shear thinning characteristics of the samples also contribute to a larger vertical height of the hydraulic jump and an undercutting phenomenon. The elasticity of the fluids contributes to a "recoil" of the hydraulic jump circle, causing the circle, after initial expansion, to shrink in size before expanding again. textcopyright 2011 American Institute of Physics.},\n\tAuthor = {Hsu, T T and Walker, T W and Frank, C.W. and Fuller, G.G.},\n\tJournal = {Physics of Fluids},\n\tNumber = {3},\n\tTitle = {Role of fluid elasticity on the dynamics of rinsing flow by an impinging jet},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-79953272487&partnerID=40&md5=59a6dd56a3416e2e57017633b5019b59},\n\tVolume = {23},\n\tYear = {2011},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-79953272487&partnerID=40&md5=59a6dd56a3416e2e57017633b5019b59}}\n\n

A series of monodisperse poly(ethylene oxide)-poly(butylene oxide) (EOBO) block copolymers were obtained with two ratios of hydrophilic/hydrophobic block lengths. We have explored the surface activity of EOBO at a clean interface and under 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) monolayers as a simple cell membrane model. At the same subphase concentration, EOBO achieved higher equilibrium surface pressures under DPPC compared to a bare interface, and the surface activity was improved with longer poly(butylene oxide) blocks. Further investigation of the DPPC/EOBO monolayers showed that combined films exhibited similar surface rheology compared to pure DPPC at the same surface pressures. DPPC/EOBO phase separation was observed in fluorescently doped monolayers, and within the liquid-expanded liquid-condensed coexistence region for DPPC, EOBO did not drastically alter the liquid-condensed domain shapes. Grazing incidence X-ray diffraction (GIXD) and X-ray reflectivity (XRR) quantitatively confirmed that the lattice spacings and tilt of DPPC in lipid-rich regions of the monolayer were nearly equivalent to those of a pure DPPC monolayer at the same surface pressures.},\n\tAuthor = {Leiske, Danielle L and Meckes, Brian and Miller, Chad E and Wu, Cynthia and Walker, Travis W and Lin, Binhua and Meron, Mati and Ketelson, Howard A and Toney, Michael F and Fuller, Gerald G},\n\tDoi = {10.1021/la2016879},\n\tJournal = {Langmuir},\n\tLanguage = {English},\n\tMonth = sep,\n\tNumber = {18},\n\tPages = {11444--11450},\n\tPmid = {21834565},\n\tTitle = {Insertion mechanism of a poly(ethylene oxide)-poly(butylene oxide) block copolymer into a {DPPC} monolayer.},\n\tUrl = {http://eutils.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&id=21834565&retmode=ref&cmd=prlinks},\n\tVolume = {27},\n\tYear = {2011},\n\tBdsk-Url-1 = {http://eutils.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&id=21834565&retmode=ref&cmd=prlinks},\n\tBdsk-Url-2 = {http://dx.doi.org/10.1021/la2016879}}\n\n

The substrates can be used for research in cell culture, and this research presents a significant advance in the technology to coat implants in order to improve cell adhesion. In the procedure presented here, a molecular solution of collagen is spread at the interface of a saline solution and air to induce fiber formation, compressed at a high speed to induce orientation and deposited on solid substrates via Langmuir-Blodgett transfer. Several interfacial techniques are employed to investigate the behavior of collagen, which is shown to be dependent on the salt concentration of the subphase as well as the temperature. After Langmuir-Blodgett transfer, primary human fibroblasts and adipose-derived stem cells are cultured on the collagen substrates. Both types of cells respond favorably to the collagen orientation and align with the deposited fibers. The technique presented here provides a simple method to produce well-controlled, oriented collagen substrates that can be used in tissue culture research or scaffolding applications without the use of additives and/or bioincompatible materials.},\n\tAuthor = {Goffin, A J and Rajadas, J and Fuller, G.G.},\n\tJournal = {Langmuir},\n\tNumber = {5},\n\tPages = {3514--3521},\n\tTitle = {Interfacial flow processing of collagen.},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-77952788615&partnerID=40&md5=1e78e2382dfa2f16c6f410adc98462a6},\n\tVolume = {26},\n\tYear = {2010},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-77952788615&partnerID=40&md5=1e78e2382dfa2f16c6f410adc98462a6}}\n\n

@article{maas_thin_2010,\n\tAbstract = {We report a new and simple method for the formation of thin films at the interface between aqueous silica Ludox dispersions and lipid solutions in decane. The lipids used are stearic acid, stearyl amine, and stearyl alcohol alongside silica Ludox nanoparticle dispersions of varying pH. At basic pH thin films consisting of a mixture of stearic acid and silica nanoparticles precipitate at the interface. At acidic and neutral pH we were able to produce thin films consisting of stearyl amine and silica particles. The film growth was studied in situ with interfacial shear rheology. In addition to that, surface pressure isotherm and dynamic light scattering experiments were performed. The films all exhibit strong dynamic rheological moduli, rendering them an interesting material for applications such as capsule formation, surface coating, or as functional membranes.},\n\tAuthor = {Maas, Michael and Ooi, Chin C and Fuller, Gerald G},\n\tDoi = {10.1021/la103492a},\n\tJournal = {Langmuir},\n\tNumber = {23},\n\tPages = {17867--17873},\n\tPmid = {21067193},\n\tTitle = {Thin film formation of silica nanoparticle/lipid composite films at the fluid-fluid interface.},\n\tUrl = {http://eutils.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&id=21067193&retmode=ref&cmd=prlinks},\n\tVolume = {26},\n\tYear = {2010},\n\tBdsk-Url-1 = {http://eutils.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&id=21067193&retmode=ref&cmd=prlinks},\n\tBdsk-Url-2 = {http://dx.doi.org/10.1021/la103492a}}\n\n

@article{weng_isovaleric_2009,\n\tAbstract = {Introduction: Elevated concentrations of isovaleric (IVA), methylmalonic (MMA), and propionic acid are associated with impaired consciousness in genetic diseases (organic acidemias). We conjectured that part of the central nervous system depression observed in these disorders was due to anesthetic effects of these metabolites. We tested three hypotheses. First, that these metabolites would have anesthetic-sparing effects, possibly being anesthetics by themselves. Second, that these compounds would modulate glycine and γ-aminobutyric acid (GABAA) receptor function, increasing chloride currents through these channels as potent clinical inhaled anesthetics do. Third, that these compounds would affect physical properties of lipids. Methods: Anesthetic EC50s were measured in Xenopus laevis tadpoles. Glycine and GABAA receptors were expressed in Xenopus laevis oocytes and studied using two-electrode voltage clamping. Pressure-area isotherms of 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) monolayers were measured with and without added organic acids. Results: IVA acid was an anesthetic in tadpoles, whereas MMA and propionic acid decreased isoflurane's EC50 by half. All three organic acids concentration-dependently increased current through α1 glycine receptors. There were minimal effects on α1β2γ2s GABAA receptors. The organic acids increased total lateral pressure (surface pressure) of DPPC monolayers, including at mean molecular areas typical of bilayers. Conclusion: IVA, MMA, and propionic acid have anesthetic effects in tadpoles, positively modulate glycine receptor function and affect physical properties of DPPC monolayers. textcopyright 2009 International Anesthesia Research Society.},\n\tAuthor = {Weng, Y and Hsu, T T and Zhao, J and Nishimura, S and Fuller, G.G. and Sonner, J M},\n\tJournal = {Anesthesia and Analgesia},\n\tNumber = {5},\n\tPages = {1538--1545},\n\tTitle = {Isovaleric, methylmalonic, and propionic acid decrease anesthetic ec50 in tadpoles, modulate glycine receptor function, and interact with the lipid 1,2-dipalmitoyl-{Sn}-glycero-3-phosphocholine},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-65349147704&partnerID=40&md5=2acd89da62269460347894a72123469c},\n\tVolume = {108},\n\tYear = {2009},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-65349147704&partnerID=40&md5=2acd89da62269460347894a72123469c}}\n\n

Our results suggest that there is an effect of the compression rate on both the structure of the layers and their rheological behavior, while the length of the chain influences only the rheology. At very low compression speeds, the surface layer of short chains does not exhibit the classical semi-dilute regime behavior, forming instead a solid phase. For fluid layers, we report on the dependence of surface viscosity upon the concentration, showing a first crossover, which happens close to the semi-dilute-concentrated regime boundary, from a scaling behavior with the concentration to an Eyring-like liquid. A second rheological transition happens at very high concentrations, near close packing, where the Newtonian liquid phase gives way to a soft solid phase. textcopyright 2009 American Chemical Society.},\n\tAuthor = {Spigone, Elisabetta and Cho, Gil-Young Y and Fuller, Gerald G and Cicuta, Pietro},\n\tDoi = {10.1021/la900385y},\n\tJournal = {Langmuir},\n\tMonth = jul,\n\tNumber = {13},\n\tPages = {7457--7464},\n\tPmid = {19374337},\n\tTitle = {Surface rheology of a polymer monolayer: {Effects} of polymer chain length and compression rate},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-67650090012&partnerID=40&md5=572302c42ee030e9828e80cea8fdda70 http://dx.doi.org/10.1021/la900385y},\n\tVolume = {25},\n\tYear = {2009},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-67650090012&partnerID=40&md5=572302c42ee030e9828e80cea8fdda70%20http://dx.doi.org/10.1021/la900385y},\n\tBdsk-Url-2 = {http://dx.doi.org/10.1021/la900385y}}\n\n

We tested the hypothesis that non-peptide, small molecule p75NTR ligands found to promote survival signaling might prevent Aβ-induced degeneration and synaptic dysfunction. These ligands inhibited Aβ-induced neuritic dystrophy, death of cultured neurons and Aβ-induced death of pyramidal neurons in hippocampal slice cultures. Moreover, ligands inhibited Aβ-induced activation of molecules involved in AD pathology including calpain/cdk5, GSK3β and c-Jun, and tau phosphorylation, and prevented Aβ-induced inactivation of AKT and CREB. Finally, a p75NTR ligand blocked Aβ-induced hippocampal LTP impairment. These studies support an extensive intersection between p75NTR signaling and Aβ pathogenic mechanisms, and introduce a class of specific small molecule ligands with the unique ability to block multiple fundamental AD-related signaling pathways, reverse synaptic impairment and inhibit Aβ-induced neuronal dystrophy and death.},\n\tAuthor = {Yang, T and Knowles, J K and Lu, Q and Zhang, H and Arancio, O and Moore, L A and Chang, T and Wang, Q and Andreasson, K and Rajadas, J and Fuller, G.G. and Xie, Y and Massa, S M and Longo, F M},\n\tJournal = {PLoS ONE},\n\tNumber = {11},\n\tTitle = {Small molecule, non-peptide p75NTR ligands inhibit {Aβ}-induced neurodegeneration and synaptic impairment},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-56149091270&partnerID=40&md5=02b623f6b9db868ddf40a767f45365dd},\n\tVolume = {3},\n\tYear = {2008},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-56149091270&partnerID=40&md5=02b623f6b9db868ddf40a767f45365dd}}\n\n

The mechanism of this phenomenon relates to charge shielding of mucin or mucin-like macromolecules that consequently undergo gelation; this gelation alters the physical properties of the ALF surface and reduces its breakup. Cations in the nebulized solution and apparent surface viscoelasticity of the ALF (more than any other ALF intrinsic physical property) appear to be responsible for the reduced tendency of the ALF to disintegrate into very small droplets.

@article{monteux_determining_2007,\n\tAbstract = {The mechanical response of particle-laden fluid interfaces is determined by measuring the internal pressures of particle-coated drops as a function of the drop volume. The particle monolayers undergoing compression-expansion cycles exhibit three distinct states: fluid state, jammed state, and buckled state. The P-V curves are compared to the surface pressure isotherms Π-A that are measured using a Langmuir trough and a Wilhelmy plate on a flat water-decane interface covered with the same particles. We find that in the fluid and jammed states, the water drop in decane can be described by the Young-Laplace equation. Therefore in these relatively low compression states, the bulk pressure measurements can be used to deduce the interfacial tension of the droplets and yield similar surface pressure isotherms to the ones measured with the Wilhelmy plate. In the buckled state, the internal pressure of the drop yields a zero value, which is consistent with the zero interfacial tension measured with the Wilhelmy plate. Moreover we find that the compressibility in the jammed state does not depend on the particle size. textcopyright the Owner Societies.},\n\tAuthor = {Monteux, C. and Kirkwood, J and Xu, H and Jung, E and Fuller, G.G.},\n\tJournal = {Physical Chemistry Chemical Physics},\n\tNumber = {48},\n\tPages = {6344--6350},\n\tTitle = {Determining the mechanical response of particle-laden fluid interfaces using surface pressure isotherms and bulk pressure measurements of droplets},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-36949025546&partnerID=40&md5=118e427c87e716c229a84d9cb6a1171d},\n\tVolume = {9},\n\tYear = {2007},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-36949025546&partnerID=40&md5=118e427c87e716c229a84d9cb6a1171d}}\n\n

In the case of mixtures of 3 and 5 μm particles, we observe crystalline layers at high or low concentration ratios, where the "impurity" particles concentrate at the grain boundaries of the crystalline structure. At intermediate ratios, the layers become highly disordered. However, in both cases, we show that the shape of the isotherms remains unchanged. In the case of the mixtures of 9 μm particles with either 3 or 5 μm particles, the smaller particles aggregate around the larger particles through capillary interaction resulting in the formation of large fractal aggregates. At high compression, these layers contain holes that seem very compressible. As a result, the surface pressure isotherms show a smaller surface pressure jump than for other mixtures. textcopyright 2007 American Chemical Society.},\n\tAuthor = {Monteux, C. and Jung, E and Fuller, G.G.},\n\tJournal = {Langmuir},\n\tNumber = {7},\n\tPages = {3975--3980},\n\tTitle = {Mechanical properties and structure of particle coated interfaces: {Influence} of particle size and bidisperse 2D suspensions},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-34147202397&partnerID=40&md5=c90a8634a98156de9fe970b07465cf47},\n\tVolume = {23},\n\tYear = {2007},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-34147202397&partnerID=40&md5=c90a8634a98156de9fe970b07465cf47}}\n\n

These compounds were used as initiators in the well-controlled living radical polymerization of isoprene, resulting in polymers with a perylene dye located at either the middle or end of the polymer. Using this approach, polyisoprenes were prepared with similar molecular weights, low polydispersities, and very good initiator efficiencies. Labeled chains were imaged on the single-molecule level in hosts of unlabeled polymer with similar composition. On the time scale from 0.2 to 2-5 s no difference between center- and end-positioned dyes was observed, suggesting that the dynamics outside of this time range should be studied. However, the most rigid host material led to the longest observed correlation times and the highest fraction of fluorophores that exhibited blinking behavior. textcopyright 2006 American Chemical Society.},\n\tAuthor = {Gavranovic, G T and Csihony, S and Bowden, N B and Hawker, C J and Waymouth, R M and Moerner, W E and Fuller, G.G.},\n\tJournal = {Macromolecules},\n\tNumber = {23},\n\tPages = {8121--8127},\n\tTitle = {Well-controlled living polymerization of perylene-labeled polyisoprenes and their use in single-molecule imaging},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-33845262042&partnerID=40&md5=b1aae16ecb359c454e7978353593e2a7},\n\tVolume = {39},\n\tYear = {2006},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-33845262042&partnerID=40&md5=b1aae16ecb359c454e7978353593e2a7}}\n\n

This polymer is characterized by a lower critical solution temperature, LCST, of 32textdegreeC; i.e., PNIPAM chains undergo a coil to globule transition as the temperature is increased above the LCST. We measure a spectacular increase in the surface shear elasticity and viscosity of PNIPAM layers as a function of the temperature around the LCST due to an increase in the amount of adsorbed species as the solvent quality decreases for PNIPAM chains. Moreover, the layers undergo a transition from a Newtonian liquidlike state to an elastic state due to an increase in intermolecular entanglements. We also show that the heating protocols have a strong influence on the rheological properties of the layers. In particular, we show that when the solutions are continuously heated from ambient temperature to well above the LCST, PNIPAM chains can be trapped in a nonequilibrium state at the air-water interface above the LCST. Last, we report on the influence that the PNIPAM bulk concentration and molecular mass have on the surface rheological properties at the air-water interface. textcopyright 2006 American Chemical Society.},\n\tAuthor = {Monteux, C. and Mangeret, R and Laibe, G and Freyssingeas, E and Bergeron, V and Fuller, G},\n\tJournal = {Macromolecules},\n\tNumber = {9},\n\tPages = {3408--3414},\n\tTitle = {Shear surface rheology of poly({N}-isopropylacrylamide) adsorbed layers at the air-water interface},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-33744485008&partnerID=40&md5=cd1b7ae9bfaa38d828844b4adb7a0547},\n\tVolume = {39},\n\tYear = {2006},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-33744485008&partnerID=40&md5=cd1b7ae9bfaa38d828844b4adb7a0547}}\n\n

@article{basavaraj_packing_2006,\n\tAbstract = {The behavior of monolayers of monodisperse prolate ellipsoidal latex particles with the same surface chemistry but varying aspect ratio has been studied experimentally. Particle monolayers at an air-water interface were subjected to compression in a Langmuir trough. When surface pressure measurements and microscopy observations were combined, possible structural transitions were evaluated. Ellipsoids of a sufficiently large aspect ratio display a less abrupt increase in the compression isotherms than spherical particles. Microscopic observations reveal that a sequence of transitions is responsible for this more gradual increase of the surface pressure. When a percolating aggregate network is used as the starting point, locally ordered regions appear progressively. When it reaches a certain surface pressure, the system "jams", and in-plane rearrangements are no longer possible at this point. A highly localized yielding of the particle network is observed. The compressional stress is relieved by flipping the ellipsoids into an upright position and by expelling particles from the monolayer. The latter does not occur for spherical particles with similar dimensions and surface chemistry. In the final stage of compression, buckling of the monolayer as a whole was observed. The effect of aspect ratio on the pressure area isotherms and on the obtained percolation and packing thresholds was quantified. textcopyright 2006 American Chemical Society.},\n\tAuthor = {Basavaraj, M G and Fuller, G.G. and Fransaer, J and Vermant, J},\n\tJournal = {Langmuir},\n\tNumber = {15},\n\tPages = {6605--6612},\n\tTitle = {Packing, flipping, and buckling transitions in compressed monolayers of ellipsoidal latex particles},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-33746630127&partnerID=40&md5=1dd2983762a933889b411bb89d8c622a},\n\tVolume = {22},\n\tYear = {2006},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-33746630127&partnerID=40&md5=1dd2983762a933889b411bb89d8c622a}}\n\n

@article{widenbrant_lipid-induced_2006,\n\tAbstract = {Alzheimer's disease is the most common cause of dementia and is widely believed to be due to the accumulation of β-amyloid peptides (Aβ) and their interaction with the cell membrane. Aβs are hydrophobic peptides derived from the amyloid precursor proteins by proteolytic cleavage. After cleavage, these peptides are involved in a self-assembly-triggered conformational change. They are transformed into structures that bind to the cell membrane, causing cellular degeneration. However, it is not clear how these peptide assemblages disrupt the structural and functional integrity of the membrane. Membrane fluidity is one of the important parameters involved in pathophysiology of disease-affected cells. Probing the Abaggregate-lipid interactions will help us understand these processes with structural detail. Here we show that a fluid lipid monolayer develop immobile domains upon interaction with Aβ aggregates. Atomic force microscopy and transmission electron microscopy data indicate that peptide fibrils are fragmented into smaller nano-assemblages when interacting with the membrane lipids. Our findings could initiate reappraisal of the interactions between lipid assemblages and Aβ aggregates involved in Alzheimer's disease. textcopyright 2006 by the Biophysical Society.},\n\tAuthor = {Widenbrant, M J O and Rajadas, J and Sutardja, C and Fuller, G.G.},\n\tJournal = {Biophysical Journal},\n\tNumber = {11},\n\tPages = {4071--4080},\n\tTitle = {Lipid-induced β-amyloid peptide assemblage fragmentation},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-33845356957&partnerID=40&md5=54cf53a7f57586289a503eb40f0b8467},\n\tVolume = {91},\n\tYear = {2006},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-33845356957&partnerID=40&md5=54cf53a7f57586289a503eb40f0b8467}}\n\n

We study this interesting phenomenon by pointwise flow-induced birefrigence (FIB) measurements in a well-known aqueous surfactant system, cetylpyridinium chloride/sodium salicylate. The dynamic nature of the local rheo-optical properties, such as birefringence and extinction angle across the gap of a Couette cell, were investigated over a range of shear rates, in particular the stress plateau region where shear stress is nearly independent of shear rate. This is probably the first application of point-wise FIB for the investigation of shear banding. The variation of optical signals along the radial direction of the Couette cell indicates that the fluid becomes inhomogeneous and forms bended structures, with either two bands or three bands across the gap, depending on the applied nominal shear rate. textcopyright 2005 The Society of Rheology.},\n\tAuthor = {Lee, J Y and Fuller, G.G. and Hudson, N E and Yuan, X F},\n\tJournal = {Journal of Rheology},\n\tNumber = {2},\n\tPages = {537--550},\n\tTitle = {Investigation of shear-banding structure in wormlike micellar solution by point-wise flow-induced birefringence measurements},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-31144474037&partnerID=40&md5=3ba2c232b499f28a8648f350110dc786},\n\tVolume = {49},\n\tYear = {2005},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-31144474037&partnerID=40&md5=3ba2c232b499f28a8648f350110dc786}}\n\n

The interfacial stress rheometer was used to measure surface rheological properties of Langmuir monolayers of poly(tert-butyl methacrylate) with molecular weights between 81.5 and 780 kg mol -1. The II - A isotherms for these monolayers show two transitions: a plateau at II approx18 mN m -1 and a bend at II approx 52 mN m -1. The properties of the films are shown to be substantially different above and below the plateau surface pressure, II p. Below II p, the monolayers are primarily viscous, and surface viscosity increases linearly with MW, while above II p, the films are more elastic, and surface viscosity is MW-independent. Computer simulations of these systems produce qualitatively similar II-A isotherms. The observed transition at II p marks the changeover from polymer chains existing in a single layer to forming regions of multilayers. textcopyright 2005 American Chemical Society.},\n\tAuthor = {Gavranovic, G T and Deutsch, J M and Fuller, G.G.},\n\tJournal = {Macromolecules},\n\tNumber = {15},\n\tPages = {6672--6679},\n\tTitle = {Two-dimensional melts: {Polymer} chains at the air - {Water} interface},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-23744480810&partnerID=40&md5=25605c431a87c47c1067d6db54d0c13c},\n\tVolume = {38},\n\tYear = {2005},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-23744480810&partnerID=40&md5=25605c431a87c47c1067d6db54d0c13c}}\n\n

This effectively compresses the particle monolayer coating and induces a transition from a fluid film to a solid film. Since the particles are firmly attached to the interface by capillary forces, the shape transitions are reversible and shape/volume curves are the same for drainage and inflation.

@article{anseth_lung_2005,\n\tAbstract = {Lung surfactant lowers surface tension and adjusts interfacial rheology to facilitate breathing. A novel instrument, the interfacial stress rheometer (ISR), uses an oscillating magnetic needle to measure the shear viscosity and elasticity of a surfactant monolayer at the air-water interface. The ISR reveals that calf lung surfactant, Infasurf, exhibits remarkable fluidity, even when exposed to air pollution residual oil fly ash (ROFA), hydrogen peroxide (H 2O2), or conditioned media from resting A549 alveolar epithelial cells (AEC). However, when Infasurf is exposed to a subphase of the soluble fraction of ROFA- or H2O2-treated AEC conditioned media, there is a prominent increase in surfactant elasticity and viscosity, representing two-dimensional gelation. Surfactant gelation is decreased when ROFA-AEC are pretreated with inhibitors of cellular reactive oxygen species (ROS), or with a mitochondrial anion channel inhibitor, as well as when A549-pO cells that lack mitochondrial DNA and functional electron transport are investigated. These results implicate both mitochondrial and nonmitochondrial ROS generation in ROFA-AEC-induced surfactant gelation. A549 cells treated with H2O2 demonstrate a dose-dependent increase in lung surfactant gelation. The ISR is a unique and sensitive instrument to characterize surfactant gelation induced by oxidatively stressed AEC.},\n\tAuthor = {Anseth, J W and Goffin, A J and Fuller, G.G. and Ghio, A J and Kao, P N and Upadhyay, D},\n\tJournal = {American Journal of Respiratory Cell and Molecular Biology},\n\tNumber = {2},\n\tPages = {161--168},\n\tTitle = {Lung surfactant gelation induced by epithelial cells exposed to air pollution or oxidative stress},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-24344437775&partnerID=40&md5=a41466fdb41d88de6d345e253091102f},\n\tVolume = {33},\n\tYear = {2005},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-24344437775&partnerID=40&md5=a41466fdb41d88de6d345e253091102f}}\n\n

@article{luinge_rheological_2004,\n\tAbstract = {The rheological behavior of different precursor poly(p-phenylene vinylene) (prec-PPV) monolayers at the air-water interface was investigated using an interfacial stress rheometer (ISR). This device nicely reveals a transition of the precursor poly(2,5-dimethoxy-1,4 phenylene vinylene) (prec-DMePPV) monolayer from Newtonian to elastic behavior with increasing surface pressure. The transition is accompanied by an increase in the modulus. This behavior coincides with the coagulation of different 2D condensed domains as revealed by Brewster angle microscopy (BAM). However, partly converted prec-DMePPV monolayers show elastic behavior even at low surface pressures, although a sudden increase of the moduli does occur. This phenomenon is attributed to enhanced hydrophobic interactions between the conjugated moieties in the partly converted polymers. The latter also explains the stretching behavior of the partly converted prec-DMePPV upon transfer in Langmuir-Blodgett-type vertical dipping. The increase of the moduli which is observed is much more gradual in the precursor poly(2,5-dibutoxy- 1,4-phenylene vinylene), prec DBuPPV, a monolayer which is in agreement with the expected expanded state of the latter monolayer.},\n\tAuthor = {Luinge, J W and Nijboer, G W and Hagting, J G and Vorenkamp, E J and Fuller, G.G. and Scheuten, A J},\n\tJournal = {Langmuir},\n\tNumber = {26},\n\tPages = {11517--11522},\n\tTitle = {Rheological behavior of precursor {PPV} monolayers},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-11244283870&partnerID=40&md5=5f11609923a563b771bb2cbac6c1477e},\n\tVolume = {20},\n\tYear = {2004},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-11244283870&partnerID=40&md5=5f11609923a563b771bb2cbac6c1477e}}\n\n

@article{stancik_structure_2003,\n\tAbstract = {The effect of shear flow on the structure and dynamics of monodisperse spherical polystyrene particles suspended at the interface between decane and water was observed. While undisturbed, the particles arrange themselves on a hexagonal lattice due to strong dipole-dipole repulsion resulting from ionizable sulfate groups on their surfaces. As the interface is subjected to shear flow, however, the lattice adopts a new semi-ordered, anisotropic state for which two distinct regimes are observed. At low particle concentrations or high shear rates, nearest neighbors in the lattice align in the flow direction and create strings of particles that slip past each other fairly readily. This results in a stretching of the overall structure and achievement of a steady state orientation in the system. In contrast, at high concentrations or low shear rates, the interparticle forces gain importance and tend to keep the particles more strongly in their lattice positions. As a result, domains within the lattice are forced to rotate, thus giving rise to movement of particles perpendicular to the flow direction. Thus a rotation, in addition to stretching, of the structure is apparent in this case.},\n\tAuthor = {Stancik, E J and Gavranovic, G T and Widenbrant, M J O and Laschitsch, A T and Vermant, J and Fuller, G.G.},\n\tJournal = {Faraday Discussions},\n\tPages = {145--156},\n\tTitle = {Structure and dynamics of particle monolayers at a liquid-liquid interface subjected to shear flow},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0037263197&partnerID=40&md5=ca696f5ac06705ac5fed926fc96a1bed},\n\tVolume = {123},\n\tYear = {2003},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0037263197&partnerID=40&md5=ca696f5ac06705ac5fed926fc96a1bed}}\n\n

The interparticle forces were tailored to produce a two-dimensional (2D) particulate network that could be reversibly broken down by means of a shear flow. Two types of suspensions have been investigated: systems with fairly strong attractive potentials in which essentially rigid bonds develop and systems with weaker attractions in which particles can still slide over each other at contact. For both suspensions interfacial shear flow causes the floes and their spatial organization to become anisotropic at various length scales. The FFT of the real space images is used to characterize the anisotropy at large length scales. Structural anisotropy at smaller length scales is deduced from the orientational dependence of the pair distribution function and from an harmonic expansion of g(r). The mechanism leading to the anisotropy during shear flow is shown to be related to a directional dependence of breakup and re-formation of floes. Interfacial flow also affects the density of the floes. The evolution of the distribution of coordination numbers with shear rate indicates that shear flow densities the rigid floes whereas the opposite occurs for the mobile ones.},\n\tAuthor = {Hoekstra, H and Vermant, J and Mewis, J and Fuller, G.G.},\n\tJournal = {Langmuir},\n\tNumber = {22},\n\tPages = {9134--9141},\n\tTitle = {Flow-{Induced} {Anisotropy} and {Reversible} {Aggregation} in {Two}-{Dimensional} {Suspensions}},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0242409115&partnerID=40&md5=6e2d994516b6191a76c4fc251b734ebc},\n\tVolume = {19},\n\tYear = {2003},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0242409115&partnerID=40&md5=6e2d994516b6191a76c4fc251b734ebc}}\n\n

@article{anseth_interfacial_2003,\n\tAbstract = {An interfacial stress rheometer has been used to study the rheological properties of a silicone oil/water interface in the presence of siloxane surfactants that are used in the personal care industry as water-in-silicone-oil emulsifiers. The surfactants are graft-type poly(dimethylsiloxane)-poly(oxyalkylene) copolymers. They appear to stabilize water-in-silicone-oil emulsions in a fashion similar to that of Pickering emulsions, in which solid particles, such as silica or clay, accumulate in the oil/water interface forming a solidlike "eggshell" that resists coalescence. These oil-soluble copolymers, when dissolved in silicone oil and contacted with water, spontaneously form small particles of a copolymer-rich phase dispersed in the oil phase. These particles appear to accumulate in the interface and act analogously to the solid particles in Pickering emulsions by forming a solidlike network in the silicone oil/water interface that can resist coalescence. The rheology of the interface is influenced by the formation and aggregation of these surfactant-rich particles in the silicone oil/water interface. Consequently, measuring the effects of different processing parameters on interfacial rheology can be used to study their effect on the formation of these surfactant-rich particles. Furthermore, the wetting behavior of the particle surface becomes more hydrophilic when exposed to water as evidenced by changes in contact angle measurements. Presumably, when these particles are in the silicone oil/water interface they present their hydrophilic poly(oxyethylene) domains toward water, resulting in a nonuniformity of surface wettability. This nonuniform surface wettability enhances these particles' ability to reside in the silicone oil/water interface.},\n\tAuthor = {Anseth, J W and Bialek, A and Hill, R M and Fuller, G.G.},\n\tJournal = {Langmuir},\n\tNumber = {16},\n\tPages = {6349--6356},\n\tTitle = {Interfacial rheology of graft-type polymeric siloxane surfactants},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0042071145&partnerID=40&md5=a141a455e330c6551f063843fd7191fc},\n\tVolume = {19},\n\tYear = {2003},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0042071145&partnerID=40&md5=a141a455e330c6551f063843fd7191fc}}\n\n

@article{pignon_orientation_2003,\n\tAbstract = {The orientation dynamics of a lyotropic colloidal suspension of sepiolite clay under extensional flow have been explored by combined dichroism and small angle light scattering measurements. Extensional flow was applied using a four-roll mill to a thin film of sepiolite suspension (rigid rods 1 μm long and 0.010 μm in diameter). Analysis of transient extensional flow reversals revealed important characteristics of the orientation dynamics of these suspensions: (i) the existence of a critical volume fraction separating isotropic behavior, where no orientation persists after stretching, from nematic behavior, where permanent orientations persist during the relaxation phase; and (ii) in the nematic domain, a critical strain rate separates two flow regimes corresponding to a stable, so-called strong flow regime above the critical strain rate and an unstable, so-called weak flow regime below it. These experimental observations agree with the theoretical predictions of the model proposed by Marrucci and Maffettone (1989, 1990) who have examined the two-dimensional form of the simple molecular model of Hess (1976) and Doi (1981). What is new in the present case is that the colloidal suspension is a three-dimensional system, whereas previous experimental validations of the model concerned only two-dimensional rodlike polymers systems [Maffettone et al.

@article{melle_rotational_2002,\n\tAbstract = {The dynamics of field-induced structures in very dilute dipolar colloidal suspensions subject to rotating magnetic fields have been experimentally studied using video microscopy. When a rotating field is imposed the chain-like aggregates rotate with the magnetic field frequency. We found that the size of the induced structures at small rotational frequencies is larger than at zero rotating frequency, i.e. when an uniaxial magnetic field is applied. At higher frequencies, the average size of the aggregates decreases with frequency following a power law with exponent -0.5 as the hydrodynamic friction forces overcome the dipolar magnetic forces, causing the chains break up. A non-thermal molecular dynamics simulations are also reported, showing good agreement with the experiments. textcopyright 2002 Elsevier Science B.V.

The DB-ROA contains the two optically modulated laser beams that are transmitted through a sheared sample in different angles. The full components of the stress tensor can be evaluated simultaneously by a single measurement of the birefringence and orientation angle of each beam. The mechanical properties are also measured simultaneously with the optical properties. This system can be applied to both steady and transient shear flows. Three types of DB-ROAs are designed. They are distinguished by the optical modulation system, that is (1) a single modulator system, (2) a synchronization of two modulators, and (3) a two individual modulator system. The performance tests were carried out and its validity was demonstrated by comparison between the optical and the mechanical measurements of the first normal stress difference. The signal-to-noise ratio was strongly affected by the choice of the oblique angle of the second beam. The design features for the different optical modulation systems are discussed.},\n\tAuthor = {Takahashi, T and Shirakashi, M and Miyamoto, K and Fuller, G.G.},\n\tJournal = {Rheologica Acta},\n\tNumber = {5},\n\tPages = {448--455},\n\tTitle = {Development of a double-beam rheo-optical analyzer for full tensor measurement of optical anisotropy in complex fluid flow},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0036671548&partnerID=40&md5=b364b20c075c68567b0a0659d82cae52},\n\tVolume = {41},\n\tYear = {2002},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0036671548&partnerID=40&md5=b364b20c075c68567b0a0659d82cae52}}\n\n

The purpose of this paper is to examine molecular orientational hydrodynamics through studies of monolayer films at the air-water interface and to understand the phenomenon of the phase transition in two dimensions. UV absorption spectroscopy was used to determine molecular orientation in hairy-rod polymeric monolayers of poly(p-phenylene) sulfonic acid (PPPSH). A well-defined extensional flow is imposed in the monolayer to study the dynamics of flow-induced anisotropy. A solvent of stearic acid (SA) at moderate concentrations is added to the polymer solution to fluidize the film, and the effect of solvent on the isotropic-nematic transition is observed. Above T IN, complete relaxation of molecules is observed after flow cessation, while a nematic, ordered phase is obtained below T IN. Measurements of the surface rheological properties were also performed to further interrogate the phase transition.},\n\tAuthor = {Yim, K S and Fuller, G.G. and Datko, A and Eisenbach, C D},\n\tJournal = {Macromolecules},\n\tNumber = {20},\n\tPages = {6972--6977},\n\tTitle = {Isotropic-nematic phase transitions of lyotropic, two-dimensional liquid crystalline polymer solutions},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0035949902&partnerID=40&md5=058464b3d34a34d99a9133f1588aa654},\n\tVolume = {34},\n\tYear = {2001},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0035949902&partnerID=40&md5=058464b3d34a34d99a9133f1588aa654}}\n\n

@article{olson_electrophoresis_2001,\n\tAbstract = {We report fluorescence microscopy studies of the electrophoresis of individual DNA molecules electrostatically adsorbed to a cationic supported lipid bilayer. Obstacles to uniform electrophoretic flow cause the 2-D chains to adopt hooked conformations similar to those previously observed in 3-D electrophoresis experiments. Analysis of the stretch-contraction dynamics allows for an estimate of the obstacle density in the bilayer. Increasing the electric field causes the DNA molecules to become more highly stretched and increases the electrophoretic mobility substantially. A comparison of the Rouse relaxation time of the polymers and the average time between chain-obstacle collisions reveals that a single-obstacle model is insufficient to describe the observed dynamics but the obstacles are not dense enough to use a reptative model. Analysis of the unhooking dynamics reveals an 80\\% increase in hydrodynamic drag as compared to free chains. Finally, we observe anomalous diffusion of the DNA chains, with a large increase in the diffusion coefficient after the repeated application of high electric fields. Implications of the flow obstacles in the engineering of separation applications are discussed.},\n\tAuthor = {Olson, D J and Johnson, J M and Patel, P D and Shaqfeh, E S G and Boxer, S G and Fuller, G.G.},\n\tJournal = {Langmuir},\n\tNumber = {23},\n\tPages = {7396--7401},\n\tTitle = {Electrophoresis of {DNA} adsorbed to a cationic supported bilayer},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0035856668&partnerID=40&md5=af79fabaabf77a089ad401e323dc887b},\n\tVolume = {17},\n\tYear = {2001},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0035856668&partnerID=40&md5=af79fabaabf77a089ad401e323dc887b}}\n\n

@article{naumann_two-dimensional_2001,\n\tAbstract = {Recent surface rheology and film balance experiments on monolayers of PEG lipopolymers and phospholipid/PEG lipopolymer mixtures at the air-water interface have revealed a new class of quasi two-dimensional physical networks. Two different kinds of associative interactions are necessary to form the network: microcondensation of alkyl chains of lipopolymers to form small clusters and water molecule mediation of the interaction between adjacent PEG clusters via hydrogen bonding. In the experiments presented here, we are interested to learn whether the physical gelation is PEG specific or whether it is a more general characteristic of lipopolymers at the air-water interface. To address this topic, we have expanded our surface rheology and film balance experiments to poly(oxazoline) lipopolymers. Our experiments indicate the occurrence of a rheological transition if the poly(oxazoline) lipopolymers consist of a dioctadecylglycerol anchor. This shows that the physical gelation among lipopolymers is not a PEG-specific phenomenon. No physical gelation is found, however, if the dioctadecylglycerol anchor of the lipopolymer is replaced by a dioctadecylamine anchor. The observed importance of the hydrophobic anchor supports our previous findings that the alkyl chain condensation should be seen as one of two kinds of physical junctions necessary for the formation of the physical network.},\n\tAuthor = {Naumann, C A and Brooks, C.F. and Fuller, G.G. and Lehmann, T and R u he, J and Knoll, W and Kuhn, P and Nuyken, O and Frank, C.W.},\n\tJournal = {Langmuir},\n\tNumber = {9},\n\tPages = {2801--2806},\n\tTitle = {Two-dimensional physical networks of lipopolymers at the air/water interface: {Correlation} of molecular structure and surface rheological behavior},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0035353375&partnerID=40&md5=865093475b0fd2be6594ff7d4850e146},\n\tVolume = {17},\n\tYear = {2001},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0035353375&partnerID=40&md5=865093475b0fd2be6594ff7d4850e146}}\n\n

The time evolution of the average orientation angle of optically isotropic, nonabsorbing particles upon inception of a shear flow was monitored by a polarization modulation method by using dilute suspensions of the particles. Since the orientation angle is a geometric property of the particles, no arbitrary assumptions on the scattering mechanism had to be made to analyze the data. The period of the damped oscillatory response of the orientation angle is related to the average aspect ratio. In the limit of strong flows the damping only depends on dispersion in particle shape. An analytical expression to relate the polydispersity of the equivalent hydrodynamic aspect ratio to the damping function is presented, as well as the applicability of the technique by studying the hydrodynamic aspect ratio and associated polydispersity in a sample containing ellipsoidal hematite particles.},\n\tAuthor = {Vermant, J and Yang, H and Fuller, G.G.},\n\tJournal = {AIChE Journal},\n\tNumber = {4},\n\tPages = {790--798},\n\tTitle = {Rheooptical determination of aspect ratio and polydispersity of nonspherical particles},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0037489757&partnerID=40&md5=710fbac9e65a8243169b59244c20d9cd},\n\tVolume = {47},\n\tYear = {2001},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0037489757&partnerID=40&md5=710fbac9e65a8243169b59244c20d9cd}}\n\n

The same holds for the excess or interfacial contribution to the first normal stress. Similarities have already been observed between these two properties in blends. Here it is investigated whether this similarity reflects a more quantitative relationship. The interfacial normal stress can be described by means of an interface anisotropy tensor. Therefore, the measured dichroism will be compared with the calculated components of this anisotropy tensor for different flow histories. These include steady-state shear flow, sudden increase in shear rate, relaxation with droplet breakup, and oscillatory flow. In all cases a proportionality factor is obtained. For strongly deformed droplets direct theoretical evidence for a quantitative relationship between rheology and rheo-optics in blends is provided. To extend this relationship to a larger window of shear rates, the size dependence of the scattering has to be taken into account.},\n\tAuthor = {Van Puyvelde, P and Moldenaers, P and Mewis, J and Fuller, G.G.},\n\tJournal = {Langmuir},\n\tNumber = {Washington, DC, United States},\n\tPages = {3740--3747},\n\tTitle = {On the existence of a stress-optical relation in immiscible polymer blends},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0033751126&partnerID=40&md5=a52a6cf61bd69942f08eb2e9a4e8a0ad},\n\tVolume = {16},\n\tYear = {2000},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0033751126&partnerID=40&md5=a52a6cf61bd69942f08eb2e9a4e8a0ad}}\n\n

However, two different behaviors are found below or above a critical frequency fc.

@article{fischer_phase_2000,\n\tAbstract = {Brewster angle microscopy, interfacial stress rheometry, and Π-A isotherm measurements are employed to characterize spread monolayers of two new cellulose derivatives, one containing octadecyl side chains, the other p-nitroaniline substituents. Similar monolayer phase behavior is found in both cases. At high surface area, a liquid phase is observed to coexist with a dilute gaseous phase. Monolayer compression eventually leads to complete coalescence to yield a uniform liquid phase. Surprisingly, a homogeneous phase is observed only at surface pressures significantly higher than that characterizing the gas-liquid phase equilibrium. This observation is attributed to dipolar repulsion between neighboring liquid domains. Compression beyond surface areas at which a continuous monolayer is observed provokes a phase transition, appearing as either a constant pressure plateau or as changes in slope in the surface pressure area isotherms. BAM images reveal only uniform surface films at molecular areas within the transition region. Surface rheological measurements indicate significant changes in monolayer mechanical properties during compression. Importantly, these changes can be correlated with isotherm shape. In all cases, monolayers exhibit a predominantly viscous behavior at high surface areas where two phases coexist. Homogeneous films achieved upon compression exhibit rheological properties that depend on both temperature and the nature of the side chain substituents. In the case of long alkyl side chains (HPC-C18), the uniform film is found to be predominantly viscous at high temperatures, and more elastic at low temperatures. This observation is interpreted as an indication of the partial crystallization of interdigitated side chains, made possible by bilayer formation. Highly dipolar chromophores incorporated as side chain substituents increase interlayer interactions and interdomain repulsion.},\n\tAuthor = {Fischer, P and Brooks, C.F. and Fuller, G.G. and Ritcey, A M and Xiao, Y and Rahem, T},\n\tJournal = {Langmuir},\n\tNumber = {2},\n\tPages = {726--734},\n\tTitle = {Phase behavior and flow properties of `hairy-rod' monolayers},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0033639812&partnerID=40&md5=208971ac08dab917eda0654a3ab4a866},\n\tVolume = {16},\n\tYear = {2000},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0033639812&partnerID=40&md5=208971ac08dab917eda0654a3ab4a866}}\n\n

Depending on its environment, it may show hydrophilic, hydrophobic, or amphiphilic properties. We have studied several PEG lipopolymers, where a PEG chain with a molecular weight (MW) of 2000 g/mol or 5000 g/mol is covalently attached to 1,2-dipalmitoyl- or 1,2-distearoyl-sn-glycero-3-phosphoethanolamine, with a Langmuir film balance and a recently developed interfacial stress rheometer. In particular, we have determined how the rheological properties of PEG molecules anchored at the air-water interface change when the polymer chains are forced into highly stretched brush conformations. Pressure-area isotherms of monolayers of PEG lipopolymers exhibit two phase transitions: a desorption transition of the PEG chains from the air-water interface at 10 mN/m and a high film pressure transition at 20-40 mN/m, but the nature of the latter transition is still poorly understood. We have observed a remarkable change of the viscoelastic properties in the range of the high-pressure transition. The monolayer is fluid below the transition, with the surface loss modulus, Gtextacutedbls, being larger than the surface storage modulus, Gtextasciiacutes, but becomes remarkably elastic above, with Gtextasciiacutes\\{\\vphantom{\\}}\\&},\n\tAuthor = {Naumann, C A and Brooks, C.F. and Fuller, G.G. and Knoll, W and Frank, C.W.},\n\tJournal = {Langmuir},\n\tNumber = {Washington, DC, United States},\n\tPages = {7752--7761},\n\tTitle = {Viscoelastic properties of lipopolymers at the air-water interface: {A} combined interfacial stress rheometer and film balance study},\n\tVolume = {15},\n\tYear = {1999}}\n\n

@article{carlson_transient_1999,\n\tAbstract = {The step shear strain behavior of elastomeric polypropylene (ePP) synthesized from an unbridged metallocene catalyst is studied using polarimetry. The elastomeric nature of ePP is presumed to arise from a multiblock structure of isotactic (iPP) and atactic (aPP) polypropylene blocks. At lower temperatures stereoregular blocks of iPP are able to crystallize while stereoirregular blocks of aPP remain amorphous. The flow behavior of ePP is compared with homopolymer blends of iPP and aPP that have the same isotactic content as ePP as well as solvent fractions of the parent ePP sample. Step shear strain experiments carried out on crystallized samples show that ePP does not completely relax from an applied strain and that a cross-linked network has formed. Imperfections in the network structure are revealed by birefringence measurements that show a partial relaxation of the polymer orientation. In contrast, crystallized homopolymer blend samples are able to completely relax after the application of a step shear strain. Step shear strain experiments of the solvent fractions of ePP suggest that the elastomeric behavior results from a combination of fractions that are able to cocrystallize to form a physically cross-linked network.},\n\tAuthor = {Carlson, E D and Fuller, G.G. and Waymouth, R M},\n\tJournal = {Macromolecules},\n\tNumber = {Washington, DC, United States},\n\tPages = {8094--8099},\n\tTitle = {Transient birefringence of elastomeric polypropylene subjected to step shear strain},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0033309413&partnerID=40&md5=a7756533c497be6c1b2ff02062c71509},\n\tVolume = {32},\n\tYear = {1999},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0033309413&partnerID=40&md5=a7756533c497be6c1b2ff02062c71509}}\n\n

The response of the Raman anisotropy of the individual components to step voltages is identical. Furthermore, cross correlation analysis of oscillatory electric field experiments shows only synchronous reorientation between the two constituents. Since neat MBBA aligns perpendicular and neat CH5 aligns parallel to the applied field, the data imply strong intermolecular interactions.

@article{kulicke_characterization_1999,\n\tAbstract = {Sodium carboxymethylcellulose (NaCMC) in solution represents a complex rheological system, since it forms aggregates and associations and hence higher-level structures and, depending on the synthesis, is only found in a molecularly dispersed form in exceptional cases. Rheo-mechanical investigations of the viscoelasticity showed that the Cox-Merz rule is not fulfilled. The aim was therefore to examine whether rheo-optics could be employed to provide more detailed conclusions about the parameters that influence the flow behavior of NaCMC than has hitherto been available with mechanical methods. The flow birefringence, Δn', rises as the degree of polymerization increases, and exhibits the same dependence on molar mass as does the viscosity: Δn' Proportional to MW3.4. As the degree of polymerization increases while the shear rate remains constant, the polymer segments become more distinctly aligned in the direction of shear. Hence increasing the degree of polymerization also affects the solution structure, i.e. the interaction of the molecules with one another. The stress-optical rule only applies to a limited extent for this system. The stress-optical coefficient, C, is almost independent of the shear rate, but is strongly influenced by the concentration and attains a limiting value of 3 x 10-8 Pa-1. C was determined for a polymer in dilute solution and the curve obtained also enabled transitions in the solution structure to be recognized.},\n\tAuthor = {Kulicke, W M and Reinhardt, U and Fuller, G.G. and Arendt, O},\n\tJournal = {Rheologica Acta},\n\tNumber = {1},\n\tPages = {26--33},\n\tTitle = {Characterization of the flow properties of sodium carboxymethylcellulose via mechanical and optical techniques},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0032770977&partnerID=40&md5=8e0f5fe288f64a25b6b9bde053962941},\n\tVolume = {38},\n\tYear = {1999},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0032770977&partnerID=40&md5=8e0f5fe288f64a25b6b9bde053962941}}\n\n

The elastomeric nature of ePP is presumed to arise from a multiblock structure of isotactic (iPP) and atactic (aPP) polypropylene blocks. Elastomeric polypropylene is a heterogeneous material in terms of tacticity that can be separated into fractions differing in tacticity. A series of samples were prepared in which one fraction was labeled with deuterium. Infrared dichroism measurements made at the C-2H stretching vibration were used to follow the relaxation behavior of fractions of various tacticity. The samples were subjected to a series of step shear strain experiments at a variety of temperatures from the melt and into the crystalline region. By simultaneously measuring birefringence (which measures the bulk sample's local orientation) and IR dichroism (which measures the orientation dynamics of the deuterated fraction), it is possible to isolate the behavior of specific populations of chains. It was revealed that chains with the highest level of tacticity crystallize first, as is expected, and strongly influence the subsequent crystallization of the remaining chains. In addition, evidence of cocrystallization between the solvent fractions was observed.},\n\tAuthor = {Carlson, E D and Fuller, G.G. and Waymouth, R M},\n\tJournal = {Macromolecules},\n\tNumber = {Washington, DC, United States},\n\tPages = {8100--8106},\n\tTitle = {Component relaxation processes within elastomeric polypropylene},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0033352738&partnerID=40&md5=5995649eff6f63c56e7be23c247e398c},\n\tVolume = {32},\n\tYear = {1999},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0033352738&partnerID=40&md5=5995649eff6f63c56e7be23c247e398c}}\n\n

@book{yim_flow-induced_1998,\n\tAbstract = {Flow-induced deformation and relaxation processes of monolayer domains at the air-water interface have been studied by using simple shear flow and extensional flow. It is found from fluorescence microscopy that deformed domains of dipalmitoyl-phosphatidylcholine (DPPC) tend to relax to circular shapes due to the line tension effects. By examining this relaxation process at low surface pressure, the value of the line tension can be calculated. In the limit of low surface pressure, the line tension was found to be λ = 1.11 textpm 0.20 texttimes 10 -12 N, which is of the same order as values found for other monolayers. A surface Capillary number Cas = ηbγ̇R2/λ is proposed to explain the two-dimensional deformation process in systems dominated by the subphase viscosity, ηb. R is the undeformed domain radius and γ̇ is the velocity gradient. For slightly deformed domains, the deformation D and orientation angle varphi are linear functions of Cas in two dimensions, and extensional flow is twice as effective in deforming domains as simple shear flow, which is similar to the case of three-dimensional droplets.},\n\tAuthor = {Yim, K S and Brooks, C.F. and Fuller, G.G. and Frank, C.W. and Robertson, C.R.},\n\tTitle = {Flow-{Induced} {Deformation} and {Relaxation} {Processes} of {Polydomain} {Structures} in {Langmuir} {Monolayer}},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0346072387&partnerID=40&md5=5d90d4108559704539b5062652a63a82},\n\tYear = {1998},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0346072387&partnerID=40&md5=5d90d4108559704539b5062652a63a82}}\n\n

The material is compositionally heterogeneous in tacticity, and its behavior is compared to that of its solvent fractions. The behavior of elastomeric polypropylene is also compared with tacticity-matched atactic/isotactic homopolymer blends. For T below Tm, mechanical rheometry shows that elastomeric polypropylene forms a more constrained network than tacticity-matched homopolymer blends. Differential scanning calorimetry reveals that the elastomeric samples crystallize at a lower temperature than blends composed of the same isotactic content. Depolarization studies show similar transitions but reveal the presence of an additional slower time scale involved with crystallizing the elastomeric sample. Data are consistent with the presumed atactic/isotactic multiblock microstructure of elastomeric polypropylene.},\n\tAuthor = {Carlson, E D and Krejchi, M T and Shah, C D and Terakawa, T and Waymouth, R M and Fuller, G.G.},\n\tJournal = {Macromolecules},\n\tNumber = {16},\n\tPages = {5343--5351},\n\tTitle = {Rheological and thermal properties of elastomeric polypropylene},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0032139975&partnerID=40&md5=1972b068287a467b5ff42b16cc67163e},\n\tVolume = {31},\n\tYear = {1998},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0032139975&partnerID=40&md5=1972b068287a467b5ff42b16cc67163e}}\n\n

@article{wheeler_time-periodic_1998,\n\tAbstract = {Using various optical and mechanical techniques we report on a shear induced structure (SIS) that results in instabilities during flow. The solution in this study is an equimolar solution of cetylpyridinium chloride and sodium salicylate. In this investigation we further probe the hypothesis of Rehage et al. that an SIS occurs [1]. We find that not only does an SIS occur but as the solution is subjected to stronger flows it becomes turbid before forming ring-like structures which alternate in intensity both spatially and temporally. Since the rings alternate periodically it is evident that the flow not only forms these structures but is also capable of destroying them as well. Simultaneously measuring birefringence and mechanical properties we observe the same periodic oscillations in the birefringence. On the other hand these ring-like structures are present in the parallel plate, cone and plate, and Taylor Couette flow cells. These rings are similar in appearance to those seen for elastic instabilities in Boger fluids seeded with mica flakes. In a constant stress rheometer the shear rate exhibits overshoots and fluctuations again resembling the behavior of elastic instabilities in Boger fluids. textcopyright 1998 Elsevier Science B.V.

Step voltage experiments show that the flexible group reorients before the rigid core. Also, oscillatory electric field experiments demonstrate that the flexible and rigid groups reorient asynchronously. In fact, at periodicities that are shorter than the bulk reorientation times, it is observed that the reorientation of the flexible part is amplified, while the motion of the rigid core is inhibited. The data suggest that the flexible group possesses a small, local dielectric anisotropy that can couple with the electric field to induce an independent, cooperative reorientation when the mobility of the rigid core is restricted.},\n\tAuthor = {Huang, K and Fuller, G.G.},\n\tJournal = {Liquid Crystals},\n\tNumber = {6},\n\tPages = {745--755},\n\tTitle = {Two-dimensional {Raman} study of the submolecular, electric field-induced reorientation of a nematic liquid crystal},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0000028458&partnerID=40&md5=2c4618a3d0da2afca6a4e25c1335d5da},\n\tVolume = {25},\n\tYear = {1998},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0000028458&partnerID=40&md5=2c4618a3d0da2afca6a4e25c1335d5da}}\n\n

A dilute system consisting of poly (butadiene) droplets dispersed in a poly(isobutene) matrix has been used as a model system. Contrary to earlier rheo-optical work on such materials, the structure has been probed in the plane formed by the flow and the velocity gradient directions. In this manner, shape anisotropy as well as the orientation angle can be monitored continuously for droplet sizes where microscopic observation becomes difficult or even impossible. During steady-state shear flow the size-dependent orientation of the droplets could be detected. It is shown that the various morphological stages caused by a sudden increase in shear rate can be identified and quantified: droplet deformation and rotation, fibril formation, and development of interfacial instabilities leading to breakup and reorientation of the resulting small droplets. These latter stages result in very characteristic light-scattering patterns. Values for anisotropy and orientation are derived from dichroism and light-scattering data and compared with theoretical results for the case of affine droplet deformation.},\n\tAuthor = {Vermant, J and Van Puyvelde, P and Moldenaers, P and Mewis, J and Fuller, G.G.},\n\tJournal = {Langmuir},\n\tNumber = {7},\n\tPages = {1612--1617},\n\tTitle = {Anisotropy and orientation of the microstructure in viscous emulsions during shear flow},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0032028802&partnerID=40&md5=e261d5e84f48e6ebb13f336dac69c32a},\n\tVolume = {14},\n\tYear = {1998},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0032028802&partnerID=40&md5=e261d5e84f48e6ebb13f336dac69c32a}}\n\n

@article{maruyama_orientation_1998,\n\tAbstract = {The two-dimensional fluid dynamics of the different phases of a fatty acid monolayer (docosanoic acid) were examined. Using Brewster angle microscopy, we studied the polydomain structure of two liquid condensed phases (the L2 and Ltextasciiacute2 phases) and the "solid", S, phase in situ during the application of extensional flow and simple shear flow. We found that only the L2 phase deformed nearly reversibly with a liquid-like response. Nonsymmetric domain deformations were, however, found for that phase at the lowest rate of strain studied with a four-roll mill. At higher strain rates, plots of the evolution of strain against time collapsed onto a single curve so that the rate of strain was independent of roller speed. Furthermore, a critical strain γc exists above which the rate of strain shows a stepwise increase despite the constant velocity of the rollers. The two other phases, the Ltextasciiacute2 and S phases, experienced flow-induced reorientation of the lattice onto which the molecules are arranged. The reorientation process was accompanied by the appearance of shear bands in the monolayers at textpm45textdegree to the extension axis of both types of flow. The shear bands observed in the Ltextasciiacute2 phase were modeled as a plastic flow accompanying the molecular tilt reorientation developed within elastic regions of the monolayer. This model describes the time evolution of the bandwidth quite well and provides strong evidence of the existence of an additional phase within the conventional Ltextasciiacute2 phase region. In simple shear flow, the velocity profile for the L2 phase across the gap of the shearing cell showed a nonlinear distribution of shear rates, which were highest at the center of the gap. Flow-induced breakup of domains was observed in the Ltextasciiacute2 phase subject to simple shear.},\n\tAuthor = {Maruyama, T and Lauger, J and Fuller, G.G. and Frank, C.W. and Robertson, C.R.},\n\tJournal = {Langmuir},\n\tNumber = {7},\n\tPages = {1836--1845},\n\tTitle = {Orientation in a fatty acid monolayer: {Effect} of flow type},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0032024260&partnerID=40&md5=a5786ca825332f8a8fc36d72e5f109ca},\n\tVolume = {14},\n\tYear = {1998},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0032024260&partnerID=40&md5=a5786ca825332f8a8fc36d72e5f109ca}}\n\n

Results indicate that bipolar and radial droplets in suspension orient in the field through very different mechanisms. Bipolar droplets are observed to rotate their defect axes in the field while radial droplets orient through a nematic distortion.

@article{wheeler_structure_1996,\n\tAbstract = {In a semi-dilute aqueous solution under certain conditions, surfactant molecules will self assemble to form wormlike micelles. The micelles are dynamic in structure since they can break and reform, providing an additional mode of relaxation. The viscoelastic properties of the wormlike micelles can be predicted using simple rheological models. For many surfactant solutions the mechanical data can be related to the optical data by the stress-optical rule. From the viscoelastic data it is possible to estimate the breaking time of the micelle. The techniques of birefringence and small angle light scattering are used to study the microstructure of a surfactant solution under simple shear and extensional flow. The sample under investigation is a solution of cetyltrimethylammonium bromide and sodium salicylate in water, with a salt to surfactant ratio of 7.7. Below a critical shear rate, the birefringence increases linearly with shear rate and the stress-optical rule is valid. The SALS patterns reveal distinctive butterfly patterns indicating that scattering is a result of concentration fluctuations that moderately couple to the flow. However, above a critical shear rate the birefringence plateaus and the stress-optical rule is no longer valid. SALS patterns show both a bright streak and a butterfly pattern. The bright streak is caused by elongated structures aligned in the direction of the flow. The oriented structures occur when the characteristic time of flow is faster than the breaking time of the micelles.},\n\tAuthor = {Wheeler, E K and Izu, P and Fuller, G.G.},\n\tJournal = {Rheologica Acta},\n\tNumber = {2},\n\tPages = {139--149},\n\tTitle = {Structure and rheology of wormlike micelles},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0000970694&partnerID=40&md5=ea1be78e8465a07e656dd2e8845c3617},\n\tVolume = {35},\n\tYear = {1996},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0000970694&partnerID=40&md5=ea1be78e8465a07e656dd2e8845c3617}}\n\n

@article{lauger_deformation_1996,\n\tAbstract = {Flow deformation and relaxation of mono- and bilayer domains of a thermotropic liquid crystal at the air-water interface have been studied by means of simultaneous application of extensional flow fields and Brewster angle microscopy measurements. In an extentional flow, mono- and bilayer domains are found to be distorted into long, stringlike domains that are stable. This is due to the absence of Rayleigh instabilities in the two-dimensional case, which otherwise lead to the occurrence of a break-up mechanism in three dimensions. However, small fluctuations in the domain thickness lead to defects that can cause breakup of the string domains followed by a retraction of the two domain ends due to line tension effects. In relaxation experiments covering both the high deformation bola-shaped regime and the small-deformation regime of slightly deformed domains, the line tensions of mono- and bilayer domains were determined. Both deformation regimes yielded the same values for the line tension of the mono- and bilayer cases. However, the line tension of the bilayer was found to be about 10 times higher than that of the monolayer. It is believed that this large difference is a result of a strong attractive dipole-dipole interaction force in the interdigitated bilayer.},\n\tAuthor = {Lauger, J and Robertson, C.R. and Frank, C.W. and Fuller, G.G.},\n\tJournal = {Langmuir},\n\tNumber = {23},\n\tPages = {5630--5635},\n\tTitle = {Deformation and relaxation processes of mono- and bilayer domains of liquid crystalline langmuir films on water},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0040389452&partnerID=40&md5=1a9345a530ed1dee500cdfe3dc8565d2},\n\tVolume = {12},\n\tYear = {1996},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0040389452&partnerID=40&md5=1a9345a530ed1dee500cdfe3dc8565d2}}\n\n

The flow was induced through two routes. In one, a four-roll mill was immersed through the monolayer to produce a well-defined extensional flow. In the second, a Langmuir-Blodgett (LB) deposition process was carried out simultaneously onto three parallel, glass plates, thereby generating a stagnation point, with extensional flow between each pair of slides. Linear dichroism was used to obtain in situ the measurements of orientation in the Langmuir films themselves, and on the glass substrates. It was found that the flows generated by the LB process induced substantial orientation within the Langmuir film, and this anisotropy was also evident in the LB films that were deposited. The velocity fields were measured using a particle tracking technique and compared against the predictions of a model assuming that the glass substrates act as line sinks of material during the LB process. It was found that the meniscus region distorts this velocity profile and leads to decreased alignment of the polymer chains.},\n\tAuthor = {Maruyama, T and Friedenberg, M and Fuller, G.G. and Frank, C.W. and Robertson, C.R. and Ferencz, A and Wegner, G},\n\tJournal = {Thin Solid Films},\n\tNumber = {1-2},\n\tPages = {76--83},\n\tTitle = {In-situ studies of flow-induced phenomena in {Langmuir} monolayers},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0030079950&partnerID=40&md5=4bbc4c4ec23224471278365ec87b0138},\n\tVolume = {273},\n\tYear = {1996},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0030079950&partnerID=40&md5=4bbc4c4ec23224471278365ec87b0138}}\n\n

The automated experiment utilizes phase modulation to alter the polarization state of light unlike conventional, polarized Raman experiments which require the manual manipulation of polarizers and multiple measurements. Polarization modulation imparts the ability to quantify the second and fourth moments of the orientation distribution function with a single measurement. The feasibility of the new experiment is demonstrated through orientation measurements of a well characterized nematic liquid crystal, 4-pentyl-(4-cyanophenyl)-cyclohexane. Additionally, since the results of the polarization-modulated technique are in excellent agreement with conventional Raman measurements, this study supports the validity of the theory describing Raman scattering from birefringent materials. textcopyright 1996 American Institute of Physics.},\n\tAuthor = {Huang, K and Archer, L A and Fuller, G.G.},\n\tJournal = {Rev.

In this article, scattering dichroism measurements are used to investigate the structural dynamics of flow-enhanced concentration fluctuations in a near-critical, semidilute polymer blend solution subjected to small-amplitude oscillatory shear flow. Our measured frequency response reveals that the behavior of the shear-induced fluctuations is governed by the relaxation time of the concentration fluctuations. Predictions from a hydrodynamic model, in good agreement with the experimental results, also indicate that the dynamics are dominated by a single relaxation time. In addition, relaxation times of the concentration fluctuations at various temperatures are calculated from dichroism data and are found to agree with those previously obtained from small-angle light scattering experiments. textcopyright 1996 Society of Rheology.},\n\tAuthor = {Lai, J and Fuller, G.G.},\n\tJournal = {Journal of Rheology},\n\tNumber = {1},\n\tPages = {153--166},\n\tTitle = {Dynamic response of a near-critical polymer blend solution under oscillatory shear flow},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0029733467&partnerID=40&md5=5e76c1ce02d8f4db27175b48fdfa25a3},\n\tVolume = {40},\n\tYear = {1996},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0029733467&partnerID=40&md5=5e76c1ce02d8f4db27175b48fdfa25a3}}\n\n

Blend component contributions to the dynamic modulus, G*(\\${\\o}mega\\$), are recovered over the full composition range by complementing dynamic mechanical rheometry with infrared polarimetry. Distinct relaxations for each component are observed. Analysis of the modulus amplitudes of the component G*(\\${\\o}mega\\$) contributions reveals that the behavior of the slower relaxing component, 1,2-PB, compares well with constraint release scaling predictions. Each component is found to have a different average number of skeletal bonds between entanglements, in agreement with the predictions of an existing entanglement theory. The components appear to adopt a single reptation tube diameter and a mutual modulus shift factor, bT(T), in each blend. Analysis of the frequency dependence of the component G*(\\${\\o}mega\\$) contributions indicates that each component's relaxation is governed by a distinct apparent glass transition temperature, Tg, and that at a constant T - Tg blend composition only mildly influences the component relaxation times. A mild increase in the 1,2-PB relaxation time in the blend suggests a possible increase in the 1,2-PB friction factor in the presence of PI. textcopyright 1994 American Chemical Society.},\n\tAuthor = {Zawada, J A and Fuller, G.G. and Colby, R H and Fetters, L J and Roovers, J},\n\tJournal = {Macromolecules},\n\tNumber = {23},\n\tPages = {6861--6870},\n\tTitle = {Component dynamics in miscible blends of 1,4-polyisoprene and 1,2-polybutadiene},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0028767787&partnerID=40&md5=c55850406267f3dbfbc46a29bffb55dc},\n\tVolume = {27},\n\tYear = {1994},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0028767787&partnerID=40&md5=c55850406267f3dbfbc46a29bffb55dc}}\n\n

First, the film collapses into small circular domains that represent fluid multilayer structures under the influence of a line tension. These multilayer disks grow in both area and number with further compression. Coalescence of domains occurs at high area fraction and is coupled with flow of the underlying monolayer. At still higher compression, additional coalescence leads to a homogeneous multilayer film. When the multilayer is allowed to expand, circular holes form. As these holes grow on further expansion, a two-dimensional foam is formed, stabilized by thin lamellae of the collapsed 8CB phase. The foam eventually breaks apart as the film expands back into the monolayer regime. Our results confirm the proposal by Xue et al. [Phys. Rev. Lett. 1992, 69, 474] that this collapse is a transition between the monolayer and a uniform trilayer composed of an interdigitated bilayer on top of a monolayer. textcopyright 1994 American Chemical Society.},\n\tAuthor = {Friedenberg, M C and Fuller, G.G. and Frank, C.W. and Robertson, C.R.},\n\tJournal = {Langmuir},\n\tNumber = {4},\n\tPages = {1251--1256},\n\tTitle = {Formation of bilayer disks and two-dimensional foams on a collapsing/expanding liquid-crystal monolayer},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0028422485&partnerID=40&md5=276e7b4ff51931cbccb1fa0aa79a7198},\n\tVolume = {10},\n\tYear = {1994},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0028422485&partnerID=40&md5=276e7b4ff51931cbccb1fa0aa79a7198}}\n\n

Transient Raman scattering, birefringence, and mechanical rheometry measurements are used to investigate segment and composition pattern relaxation dynamics. The birefringence was determined to be primarily form birefringence, and its relaxation rate was found to decrease dramatically in the vicinity of the MST. At temperatures close to the MST, the shear stress, first normal stress difference, and segment orientation anisotropy (from Raman scattering measurements) relaxation rates also decreased. Slowing down of the first normal stress difference and segment orientation anisotropy relaxations was found to be less dramatic than that of the birefringence relaxation but more pronounced than that of the shear stress relaxation. A decrease in the relaxation rate of segment orientation anisotropy close to the MST is proposed to result from the coupling of segmental and composition pattern relaxations due to tethering of chain segments to the domain interface. textcopyright 1994 American Chemical Society.},\n\tAuthor = {Archer, L A and Fuller, G.G.},\n\tJournal = {Macromolecules},\n\tNumber = {24},\n\tPages = {7152--7156},\n\tTitle = {Pattern and segment relaxation in a block copolymer melt following step shear flow},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0028547968&partnerID=40&md5=3def1188f25687b249c8d4a22d756028},\n\tVolume = {27},\n\tYear = {1994},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0028547968&partnerID=40&md5=3def1188f25687b249c8d4a22d756028}}\n\n

The method provides a means by which the blend dynamic modulus G*(\\${\\o}mega\\$) may be separated into the individiual contributions due to each of the blend components. This separation is made possible by converting the observables of dynamic infrared 1,3-dichroism and birefringence experiments to those of dynamic shear stress experiments through the use of constitutive relations and the application of the stress-optic rule. The approach is extended to cover blend systems which exhibit orientational coupling, an effect which influences the optical anisotropies but does not contribute to the state of stress. Validity of the analysis technique is demonstrated by studying highly entangled miscible blends of 1,4-polyisoprene, PI (Mw = 75 000), and 1,2-polybutadiene, 1,2-PB (Mw = 204 000), containing a fraction of deuterium-labeled PI chains (Mw = 90 000).

It is found that at temperatures below the glass transition temperature of poly(styrene), segments in both poly(styrene) and poly(butadiene) blocks preferentially align normal to the interface separating microdomains. However, at temperatures greater than the glass transition temperature of poly(styrene), segment orientation disappears. At this temperature, a dramatic decrease in birefringence is also observed.

Excellent agreement is observed between the form dichroism calculated from measured scattering intensities and the dichroism measured by optical polarimetry. In addition, a possible mechanism of dipolar coupling between the large critical concentration fluctuations and the electric field is proposed. Similar simultaneous SALS and birefringence measurements confirm this model of dipolar interaction. textcopyright 1994 American Institute of Physics.},\n\tAuthor = {Wirtz, D and Werner, D E and Fuller, G.G.},\n\tJournal = {The Journal of Chemical Physics},\n\tNumber = {2},\n\tPages = {1679--1686},\n\tTitle = {Structure and optical anisotropies of critical polymer solutions in electric fields},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0001021647&partnerID=40&md5=94db56b4e1f2d34e6bc320ed7a46abee},\n\tVolume = {101},\n\tYear = {1994},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0001021647&partnerID=40&md5=94db56b4e1f2d34e6bc320ed7a46abee}}\n\n

Between the onset of the isotherm and collapse, the polymer forms a continuous film of uniform thickness. The density of this film is the same as in the bulk polymer, and the film thickness depends on the area per molecule. The theory of tethered polymers predicts an entropic contribution to the free energy of the system due to deformation of the polymer coils. We propose a thermodynamic analysis in which we mathematically separate the contributions to the surface pressure from the head groups and from the stretching of the polymer chains. In addition, we investigate the influence of the subphase composition (aqueous solutions of CaCl 2, poly(ethylenimine), HCl, FeCl 3, NH 3) and compare the isotherm with a model system for the isolated head group. Based on the thermodynamic analysis and the comparison of isotherms, we conclude that-in the case of a chain length of approximately 100 σ-bonds - there is no significant entropic contribution from the polymer chains. textcopyright 1994 American Chemical Society.},\n\tAuthor = {Goedel, W A and Wu, H and Friedenberg, M C and Fuller, G.G. and Foster, M and Frank, C.W.},\n\tJournal = {Langmuir},\n\tNumber = {11},\n\tPages = {4209--4218},\n\tTitle = {Monolayers of perfluoropolyethers with a hydrophilic head group},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0000609308&partnerID=40&md5=9243bbaddecd53e345b4448faa7b94a5},\n\tVolume = {10},\n\tYear = {1994},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0000609308&partnerID=40&md5=9243bbaddecd53e345b4448faa7b94a5}}\n\n

Solutions prepared using three molecular weights ranging from one to four million were studied. Time-temperature superposition was observed to apply for these solutions up to and including the onset of an apparent shear thickening of the steady shear and first normal stresses. Optical measurements employing turbidity and scattering dichroism determined that concentration fluctuations were enhanced by flow and grew parallel to the vorticity axis below the critical velocity gradient for the onset of the apparent shear thickening effect. Prior to the onset of thickening, the fluctuations were observed to rearrange and orient parallel to the flow direction. Second normal stress difference measurements indicate these solutions have a negative ratio of the second to the first normal stress differences. It is interesting to point out that the ratio tends to zero in the vicinity of the shear rate range at which shear thickening occurs. textcopyright 1993 Steinkopff-Verlag.},\n\tAuthor = {Moldenaers, P and Yanase, H and Mewis, J and Fuller, G.G. and Lee, C S and Magda, J J},\n\tJournal = {Rheologica Acta},\n\tNumber = {1},\n\tPages = {1--8},\n\tTitle = {Flow-induced concentration fluctuations in polymer solutions: {Structure}/property relationships},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0001979872&partnerID=40&md5=7b5d10d0244ab8df8a0d1b222768b58a},\n\tVolume = {32},\n\tYear = {1993},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0001979872&partnerID=40&md5=7b5d10d0244ab8df8a0d1b222768b58a}}\n\n

The results indicate that at lower concentrations, high aspect ratio fibrils are formed upon application of the electric fields. As the concentration is increased, branching of the fibrillar structure reduces the anisotropy of the suspension with a subsequent decrease of the measured dichroism. The time scales of structure formation and relaxation are also considered. The response time of the fluid decreases as the applied field is increased and as the particle volume fraction is decreased.

This phenomenon is the result of anisotropic flow-induced growth of concentration fluctuations, which can be predicted qualitatively by the coupled equations of motion for the concentration and velocity fields. We have investigated the growth of concentration fluctuations of poor and near-\\$þeta\\$ semidilute solutions of polystyrene in dioctyl phthalate (PS/DOP) subject to plane extensional flow at temperatures above the quiescent cloud point. Scattering dichroism and small-angle light scattering (SALS) indicate that concentration fluctuations grow perpendicular to the principal axis of extension for low strain rates. For higher extensional rates, fourfold symmetry appears in the structure factor, with intensity maxima on the axes at 45textdegree to the principal axes. This fourfold symmetry is predicted by a recent theoretical model. We also show that the strength of flow-induced scattering is linear to first order in the ratio of viscoelastic stress to osmotic pressure. textcopyright 1993 American Chemical Society.},\n\tAuthor = {Van Egmond, J W and Fuller, G.G.},\n\tJournal = {Macromolecules},\n\tNumber = {26},\n\tPages = {7182--7188},\n\tTitle = {Concentration fluctuation enhancement in polymer solutions by extensional flow},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0027840348&partnerID=40&md5=61fedcf01c8c8b48c570705fb0d03fb4},\n\tVolume = {26},\n\tYear = {1993},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0027840348&partnerID=40&md5=61fedcf01c8c8b48c570705fb0d03fb4}}\n\n

@article{dhaene_scattering_1993,\n\tAbstract = {Shear thickening in concentrated colloidal dispersions of sterically stabilized PMMA particles has been investigated systematically, both mechanically and optically. Two types of shear thickening were distinguished. At the highest volume fractions, a discontinuous increase of the viscosity occurs at some critical point (in either the value of the stress or the velocity gradient). A further increase of the applied stress results in an erratic flow behavior. At lower concentrations the viscosity increases more gradually and the flow remains smooth. Dichroism experiments performed on a flowing dispersion and probing the structure in the 1-2 plane of simple shear flow do not show marked differences between a dispersion sheared in the upper Newtonian region and a continuously shear thickening sample. Moreover, it was also demonstrated that the type of shear thickening has no influence on the equilibrium values of the dichroism. However, a discontinuously shear thickening sample, sheared beyond the critical conditions, shows erratic, time-dependent transitions. The relaxation of the dichroism, after cessation of the flow, shows a marked increase in time scale compared to the relaxation time for shear rates smaller than the critical value. This enhanced relaxation process suggests that the discontinuity in viscosity is associated with the formation of very large, anisotropic aggregates of particles, which relax by both disorientation and disintegration. This behavior is closely related to the relaxation of the shear stress for a sample sheared beyond the critical conditions, which also shows two relaxation mechanisms. textcopyright 1993 Academic Press.

The objective of this work was to understand the dynamics of the orientation and relaxation processes and to relate these behaviours to the structural characteristics of the polymeric material. In this study we considered materials suitable for nonlinear optical applications. In particular, thin polymer films, either doped with nonlinear optical chromophores or films with the chromophores covalently bonded to side groups were studied. Orientation of these chromophores was achieved by the application of an external electric field. Ellipsometry was used to measure the birefringence resulting from chromophore orientation and the steady state and transient behaviours were studied. Materials characteristics studied included method of chromophore incorporation, chromophore concentration, spacer length. and molecular weight. Our results showed that the polymer structure, specifically the tacticity, was the dominant factor determining the steady state and transient behaviours. The relationship between monomer and polymer structure and the resulting effect on the orientation dynamics is discussed. Qualitative agreement with theoretical predictions was obtained for the simpler guest/host system, but the model was shown to be inadequate to explain the behaviours of the more complex systems studied. The results reported here have provided valuable insight into the molecular processes that occur during the chromophore orientation and relaxation, and the effects of structural characteristics of the polymers on these mechanisms.},\n\tAuthor = {Hoffmann, C L and Man, H T and Fuller, G.G.},\n\tJournal = {Acta Polymerica},\n\tNumber = {1},\n\tPages = {39--49},\n\tTitle = {Orientation dynamics of side chain polymers subject to electric fields. {Part} {I}. {Steady} state},\n\tVolume = {44},\n\tYear = {1993}}\n\n

@article{meyer_investigation_1993,\n\tAbstract = {The complementary rheooptical techniques of birefringence and dichroism are used to investigate the dynamics of xanthan gum in dilute/semidilute solution. Because xanthan self-aggregates, there are a range of very different length scales of molecules in solution which the optical methods probe. Birefringence results give information about segmental orientation in flow while scattering dichroism allows interrogation of the much larger aggregate orientation. Two xanthan samples are studied and the results are compared with previous studies. Birefringence and dichroism measurements show very different orientational and relaxational responses in shear flow, indicative of the differences between the structures examined by the two techniques. Dichroism steady-state orientation angle and birefringence/dichroism relaxation results also indicate a critical concentration at approximately 2000 ppm which coincides with that found in the literature by several other investigators and explained by some to be a critical concentration of aggregation. Dichroism measurements detect the presence of aggregates though at concentrations as low as 50 ppm, far below this critical concentration. Overshoots in dichroism, birefringence, and stress signals at approximately 2 strain units are also discussed in light of this aggregation phenomenon. The addition of salt was found to greatly enhance the dichroism signal, providing further evidence that the dichroism signal monitors aggregate dynamics. textcopyright 1993 American Chemical Society.},\n\tAuthor = {Meyer, E L and Fuller, G.G. and Clark, R C and Kulicke, W M},\n\tJournal = {Macromolecules},\n\tNumber = {3},\n\tPages = {504--511},\n\tTitle = {Investigation of xanthan gum solution behavior under shear flow using rheooptical techniques},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0027540891&partnerID=40&md5=bd2001e2961e52950f370590ab74d691},\n\tVolume = {26},\n\tYear = {1993},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0027540891&partnerID=40&md5=bd2001e2961e52950f370590ab74d691}}\n\n

The oligomers had molecular weights ranging from well below the critical molecular weight for entanglement Me, to several times Me. For the oligomer/network system, the magnitude of the coupling coefficient was found to remain constant at about unity over the range of network crosslink densities, oligomer molecular weights and degrees of swelling examined, thereby confirming the D n.m.r. experiments performed on the same samples. For the oligomer/polymer system, orientational coupling effects were examined as a function of oligomer molecular weight and temperature. It was found that unentangled oligomers experienced almost complete coupling, while fully entangled melts were subject to a much lower coupling. In addition, it was found that the magnitude of the coupling is independent of temperature, indicating that these orientation correlations are entropic in nature, arising from the packing entropy of chain segments. An orientational dependent lattice model, proposed originally by DiMarzio, was found suitable for predicting experimental results. textcopyright 1992.},\n\tAuthor = {Ylitalo, C M and Zawada, J A and Fuller, G.G. and Abetz, V and Stadler, R},\n\tJournal = {Polymer},\n\tNumber = {14},\n\tPages = {2949--2960},\n\tTitle = {Oligomers as molecular probes of orientational coupling interactions in polymer melts and networks},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-37949000959&partnerID=40&md5=877276ff9a6235437327e43868cdd3ff},\n\tVolume = {33},\n\tYear = {1992},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-37949000959&partnerID=40&md5=877276ff9a6235437327e43868cdd3ff}}\n\n

@article{van_egmond_time-dependent_1992,\n\tAbstract = {A small-angle light-scattering experiment probing the time-dependent behavior of a semidilute polymer solution under simple shear is presented. Specifically, this paper investigates time-dependent anisotropic growth and orientation of concentration fluctuations in a semidilute solution of polystyrene in dioctyl phthalate above the quiescent cloud-point temperature. Two flow cells, which permitted investigation of the structure and dynamics of concentration fluctuations in both the flow-shear and the flow-vorticity planes, were used. Concentration fluctuations were found to be enhanced anisotropically by the shear flow in both planes. In the flow-vorticity plane, shear-enhanced concentration fluctuations orient along the voracity direction, while in the flow-shear plane, the axis of average orientation is at an angle between 135textdegree and 45textdegree to the direction of flow. Qualitative trends of this anisotropic growth of concentration fluctuations are in agreement with the predictions of the Helfand-Fredrickson model in the flow-shear plane. Furthermore, the Onuki-Doi theory relating the scattering dichroism to the structure factor has been verified experimentally by comparing scattering dichroism calculated from scattering patterns with previous experimentally measured dichroism. Scattering dichroism, both calculated from structure factors and experimentally determined over a range of shear rates and temperatures, is demonstrated to depend only on the Weissenberg number. Relaxation of shear-enhanced fluctuations on cessation of flow allowed for the calculation of a diffusion coefficient. textcopyright 1992 American Institute of Physics.},\n\tAuthor = {Van Egmond, J W and Werner, D E and Fuller, G.G.},\n\tJournal = {The Journal of Chemical Physics},\n\tNumber = {10},\n\tPages = {7742--7757},\n\tTitle = {Time-dependent small-angle light scattering of shear-induced concentration fluctuations in polymer solutions},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-3743065618&partnerID=40&md5=ff2ce0c64b36861d07cab95190adc8a4},\n\tVolume = {96},\n\tYear = {1992},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-3743065618&partnerID=40&md5=ff2ce0c64b36861d07cab95190adc8a4}}\n\n

A detailed analysis of the experiment based on Jones-Mueller matrix calculus is presented. Jones and Mueller matrices that take into account the integrated effect of the deformed sample's birefringence are developed for a Raman scattering element, using either the 0textdegree or 180textdegree scattering geometries. To test the predictions of the theory a Raman scattering system, based on high-speed phase modulation (50 kHz) of the incident light coupled with phase-sensitive detection, has been developed. This system is also capable of simultaneously measuring birefringence. Single-step reversal extension and step strain experiments were conducted using a polyisobutylene melt. Experiments were done using the Raman scattered light associated with the v stretching vibration of C-H groups present in the specimen. The results obtained indicate that the Raman signal ratios all depend on the second- and fourth-order moments of the orientation distribution function of polymer segments and on the sample's birefringence. textcopyright 1992.},\n\tAuthor = {Archer, L A and Fuller, G.G. and Nunnelley, L},\n\tJournal = {Polymer},\n\tNumber = {17},\n\tPages = {3574--3581},\n\tTitle = {Dynamics of polymeric liquids using polarization-modulated laser {Raman} scattering},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0342968345&partnerID=40&md5=de8f9f42688cf01c58a398beb500dcd4},\n\tVolume = {33},\n\tYear = {1992},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0342968345&partnerID=40&md5=de8f9f42688cf01c58a398beb500dcd4}}\n\n

@article{wirtz_electric-field-induced_1992,\n\tAbstract = {In the vicinity of the coexistence curve, binary solutions exhibit large concentration fluctuations. Such fluctuations can be anisotropically distorted through the application of an electric field, which induces both electric birefringence and enhanced forward light scattering as the system approaches the coexistence curve. Using time-dependent small-angle light scattering (SALS) and form dichroism measurements on semidilute polystyrene/cyclohexane systems (molecular weight range 400 000-1 800 000), two new phenomena have been observed: electric scattering dichroism in the one-phase region and electric-field-induced remixing in the two-phase region. A mean-field theory that predicts the evolution of the scattering patterns in the presence of an electric field above the coexistence curve has been developed. In particular, it is predicted that, in the plane perpendicular to the propagation of the incident light, circular scattering patterns become elliptical patterns having the minor axis along the direction of the applied field. As a consequence, scattering dichroism is shown to be induced in the vicinity of the critical point. Moreover, the same phenomenological model predicts that the presence of an electric field lowers the coexistence curve and results in electric-field-induced remixing of binary mixtures at a temperature below the quiescent coexistence curve. The influence of temperature, molecular weight, and concentration of the polymer in solution as well as the influence of the electric field strength on SALS patterns and induced scattering dichroism measurements is studied. The experimental observations are in fairly good agreement with the trends predicted by a phenomenologically-based, mean-field theory. textcopyright 1992 American Chemical Society.},\n\tAuthor = {Wirtz, D and Berend, K and Fuller, G.G.},\n\tJournal = {Macromolecules},\n\tNumber = {26},\n\tPages = {7234--7246},\n\tTitle = {Electric-field-induced structure in polymer solutions near the critical point},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0001390506&partnerID=40&md5=2d7e51e7826a4bcee0f257bd4c7f2c25},\n\tVolume = {25},\n\tYear = {1992},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0001390506&partnerID=40&md5=2d7e51e7826a4bcee0f257bd4c7f2c25}}\n\n

@article{fuller_infrared_1991,\n\tAbstract = {A rheo-optical technique to measure dynamic infrared dichroism was used with deuterium labeling to study component relaxation in a variety of multicomponent polymer melts. For each sample overall relaxation was observed simultaneously using birefringence measurements. Nearly monodisperse poly(ethylene propylene) samples were used to construct three different sets of bidisperse blends. For each sample, results for step-strain relaxation of each component and of the total sample are presented and discussed. Effects of intermolecular orientational coupling were observed and a coupling strength of 0.45 was measured. The results of these experiments were compared to a reptation-based constraint release model, and a qualitative agreement was found. Using nearly monodisperse polybutadiene block copolymers, selected segment relaxations following step strains were examined. It was found that segments located at chain ends relax faster than segments located at chain centers, and that both the Rouse model and the tube model of Doi and Edwards correctly predict the qualitative features of segmental relaxation. The tube model, however, gave exact quantitative agreement with experiment when the effects of orientational coupling interactions of strength 0.4 were incorporated into the model. Additional studies on orientational coupling effects in polymer melts were conducted using a series of monodisperse polybutadiene oligomers dissolved in a polybutadiene polymer matrix. The oligomers had molecular weights ranging from well below the entanglement molecular weight, Me, to several times Me. The results indicate that orientational coupling interactions are significantly reduced for oligomers with molecular weights above Me. This technique can be further applied to study component dynamics in blends of two different polymers where the relaxation of each polymer in the melt can be observed separately. textcopyright 1991.},\n\tAuthor = {Fuller, G.G. and Ylitalo, C M},\n\tJournal = {Journal of Non-Crystalline Solids},\n\tNumber = {PART 2},\n\tPages = {676--684},\n\tTitle = {Infrared polarimetry studies for multicomponent polymer melts},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0026413749&partnerID=40&md5=ed7f67a2fdbfda2041df083ca58d13e9},\n\tVolume = {131-133},\n\tYear = {1991},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0026413749&partnerID=40&md5=ed7f67a2fdbfda2041df083ca58d13e9}}\n\n

@article{kornfield_third_1991,\n\tAbstract = {A recently developed rheooptical technique that simultaneously measures infrared dichroism and birefringence is used to study bidisperse, linear polymer melts in an oscillatory shear. The method was used to individually measure the contribution of the high and low molecular weight components to the third normal stress difference. This was accomplished by measuring the infrared dichroism due to deuterium-labeled polymers. Binary blends are prepared from nearly monodisperse pairs of hydrogenated and deuteriated polyisoprenes of molecular weights 53 000 and 370 000 with volume fractions of long polymer, ΦL, of 0.10, 0.20, 0.30, 0.50, and 0.75.

@article{burghardt_role_1991,\n\tAbstract = {The role of director tumbling in the dynamic response of polymer liquid crystals is investigated. A flow experiment on an oriented monodomain confirms director tumbling in liquid crystalline poly(benzyl glutamate) solutions. Mechanical and optical rheometric techniques are used to investigate the behavior of textured liquid crystal solutions in slow shear flows. Director tumbling in this system is shown to play a major role in determining the rheological behavior, particularly in that it results in large distortions in the director profile, leading to significant distortional elastic effects. The rheological data are interpreted in terms of general scaling arguments based on the assumption that the director field responds over a length scale associated with the texture rather than the macroscopic flow dimension. Comparison of our results with model calculations using the Leslie-Ericksen continuum model further suggests that the texture length scale is refined in response to increased shear rates, as a mechanism for limiting distortional free energy in the shear flow; rheooptical evidence for this texture refinement is described. A broad range of experimental data may be explained by these arguments, including a widely observed relaxation scaling law.},\n\tAuthor = {Burghardt, Wesley R and Fuller, Gerald G},\n\tJournal = {Macromolecules},\n\tNumber = {9},\n\tPages = {2546--2555},\n\tTitle = {Role of director tumbling in the rheology of polymer liquid crystal solutions},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0026140629&partnerID=40&md5=b1a9632b1b06b95fdc2c679d2fb283ea},\n\tVolume = {24},\n\tYear = {1991},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0026140629&partnerID=40&md5=b1a9632b1b06b95fdc2c679d2fb283ea}}\n\n

@article{cathey_optical_1990,\n\tAbstract = {The optical and mechanical responses of dilute and semidulute solutions of flexible polymer molecules to extensional flow are measured. The optical property of interest, the birefringence, is sensitive to the local orientation of the polymer coil, whereas the mechanical property investigated, the effective extensional viscosity, is sensitive to the overall deformed length of the molecule. These two properties are simultaneously measured as a function of the rate of strain by using an opposing jets apparatus. Solutions ranging from 50 to 300 ppm by weight polystyrene dissolved in both tri-cresyl phosphate, a good solvent at 22textdegreeC, and di-octyl phthalate, a theta solvent at 22textdegreeC, were studied. The results show that the response of the flexible polymer is dependent on the solvent quality. Both the local orientation and the deformed length of the molecule increase with increasing strain rate at low rates of strain for both solvents. However, in the theta solvent at high rates of strain the birefringence saturates, while the effective extensional viscosity drops with increasing strain rate. This indicates a decrease in the overall deformed length of the molecule at high strain rates due to the decrease in the residence time of the coil in the flow field. In the good solvent, molecular entanglements begin to affect the extensional viscosity at high strain rates if the concentration and molecular weight are sufficiently large. The response of flexible polymers to extensional flow is qualitatively compared to numerical simulations based on bead-spring and bead-rod models. Although these models are able to capture the saturation of birefringence under conditions where the extensional viscosity is still changing, they do not predict the observed maxima in extensional viscosity as a function of strain rate. textcopyright 1990.},\n\tAuthor = {Cathey, C A and Fuller, G.G.},\n\tJournal = {Journal of Non-Newtonian Fluid Mechanics},\n\tNumber = {1},\n\tPages = {63--88},\n\tTitle = {The optical and mechanical response of flexible polymer solutions to extensional flow},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0025225075&partnerID=40&md5=ed56f1e3061b7433687bcc091d897795},\n\tVolume = {34},\n\tYear = {1990},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0025225075&partnerID=40&md5=ed56f1e3061b7433687bcc091d897795}}\n\n

Two different polymers were studied: polybutadiene and poly (ethylene propylene). The first type consisted of a triblock with a short middle block labeled and a diblock with a short end block labeled, while the second type consisted of a triblock with three equal blocks and the end blocks labeled. Results of step strain experiments at -10textdegreeC for polybutadiene and at room temperature for poly(ethylene propylene) indicated that segments located at chain ends relax faster than segments located at chain centers. These experimental data were compared to the predictions of two molecular models: the bead-spring model of Rouse and the tube model of Doi and Edwards, and it was found that both models correctly predict the qualitative features of segmental relaxation. However, the tube-model predictions were closer to the experimental results. In addition, when the effects of orientational coupling interactions between segments in the melt were incorporated into this model, its predictions quantitatively agreed with the experimental results. The orientational coupling coefficient for poly(ethylene propylene) was 0.45 as measured from previous work, and for polybutadiene it was found to be 0.4. textcopyright 1990 Steinkopff.},\n\tAuthor = {Ylitalo, C M and Fuller, G.G. and Abetz, V and Stadler, R and Pearson, D S},\n\tJournal = {Rheologica Acta},\n\tNumber = {6},\n\tPages = {543--555},\n\tTitle = {Relaxation dynamics of selected polymer chain segments and comparison with theoretical models},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0001664108&partnerID=40&md5=dcc9ec4d5cc3393b61a758914d1853e4},\n\tVolume = {29},\n\tYear = {1990},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0001664108&partnerID=40&md5=dcc9ec4d5cc3393b61a758914d1853e4}}\n\n

@article{kornfield_stress_1990,\n\tAbstract = {Results are reported for the dynamic moduli, Gtextasciiacute and Gtextacutedbl, measured mechanically, and the dynamic third normal stress difference, measured optically, of a series bidisperse linear polymer melts under oscillatory shear. Nearly monodisperse hydrogenated polyisoprenes of molecular weights 53000 and 370000 were used to prepare blends with a volume fraction of long polymer, ΦL, of 0.10, 0.20, 0.30, 0.50, and 0.75. The results demonstrate the applicability of birefringence measurements to solve the longstanding problem of measuring the third normal stress difference in oscillatory flow. The relationship between the third normal stress difference and the shear stress observed for these entangled polymer melts is in agreement with a widely predicted constitutive relationship: the relationship between the first normal stress difference and the shear stress is that of a simple fluid, and the second normal stress difference is proportional to the first. These results demonstrate the potential use of 1,3-birefringence to measure the third normal stress difference in oscillatory flow. Further, the general constitutive equation supported by the present results may be used to determine the dynamic moduli from the measured third normal stress difference in small amplitude oscillatory shear. Directions for future research, including the use of birefringence measurements to determine N2/N1 in oscillatory shear, are described. textcopyright 1990 Steinkopff.},\n\tAuthor = {Kornfield, J A and Fuller, G.G. and Pearson, D S},\n\tJournal = {Rheologica Acta},\n\tNumber = {2},\n\tPages = {105--116},\n\tTitle = {Stress optical measurement of the third normal stress difference in polymer melts under oscillatory shear},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0000640507&partnerID=40&md5=dc164049b641c15450418f1d402b043f},\n\tVolume = {29},\n\tYear = {1990},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0000640507&partnerID=40&md5=dc164049b641c15450418f1d402b043f}}\n\n

@article{johnson_dynamics_1990,\n\tAbstract = {The dynamics of colloidal, axisymmetric particles suspended in non-Newtonian, polymeric liquids are examined by using optical techniques that are capable of following their average orientation. Polarimetry measurements of birefringence and dichroism are used on dispersions of colloidal iron oxide spheroids and small-angle light scattering is used on hardened, prolate human red blood cells. A variety of suspending liquids are used including Boger fluids designed to have some of the attributes of a second order fluid under steady state flow conditions, and concentrated polystyrene solutions with rheological properties similar to more commonly encountered polymer liquids. As a result of the non-Newtonian properties of the polymeric suspending fluids, and in particular the presence of normal stresses, the particles were observed to drift out of the orbits associated with their motion in Newtonian fluids. As predicted by Cohen and coworkers, in flows where the elastic forces on the particles dominate Brownian forces, the particles tend to drift away from orientations favoring the flow direction and towards the vorticity axis. When Brownian forces are large compared with the elastic forces, alignments in the flow direction are more probable. This trend, however, was only observed when the Boger fluids were used as suspending fluids. Although the polystyrene solutions possessed shear viscosities and first normal stress difference coefficients that were comparable in magnitude to those of the Boger fluids, only orientations along the flow direction were found. textcopyright 1990.},\n\tAuthor = {Johnson, S J and Salem, A J and Fuller, G.G.},\n\tJournal = {Journal of Non-Newtonian Fluid Mechanics},\n\tNumber = {1},\n\tPages = {89--121},\n\tTitle = {Dynamics of colloidal particles in sheared, non-{Newtonian} fluids},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0025112097&partnerID=40&md5=a69f36021617fc34bab8339893a1b187},\n\tVolume = {34},\n\tYear = {1990},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0025112097&partnerID=40&md5=a69f36021617fc34bab8339893a1b187}}\n\n

A transition from a Newtonian plateau to strain thickening behavior was identified and time-temperature superposition of the effective viscosity data was found to apply. Comparison of the optical and mechanical results indicates that a stress-optical rule does not apply in extension. At rates of strain above 50 s -1, the flow became time-dependent and unstable.

@article{burghardt_transient_1990,\n\tAbstract = {Calculations of a variety of transient flow phenomena based on the Leslie--Ericksen model for nematic liquid crystals are presented. Emphasis is placed on the behavior of nematics subject to director tumbling. A wide range of complicated transient phenomena such as oscillatory responses are predicted when the Ericksen number is sufficiently high to cause significant rotation of the director at steady state. Particular attention is given to relaxation processes such as constrained elastic recoil and stress relaxation that arise from the interaction of the relaxing director profile with the viscous response of the nematic. These relaxation processes are dramatically different in tumbling and flow aligning systems, due to the saturation of the director profile at high Ericksen number for the flow aligning case. A qualitative physical model of a textured polymer liquid crystal is presented in which the dynamics on a local scale governed by the distance between defects are assumed to be similar to the macroscopic dynamics presented in these calculations. By assuming (i) director tumbling and (ii) the existence of a limiting Ericksen number in polymer systems, a wide range of published observations in lyotropic liquid crystalline polymer solutions may be qualitatively reproduced.},\n\tAuthor = {Burghardt, Wesley R},\n\tDoi = {10.1122/1.550151},\n\tJournal = {Journal of Rheology},\n\tMonth = aug,\n\tNumber = {6},\n\tPages = {959},\n\tTitle = {Transient shear flow of nematic liquid crystals: {Manifestations} of director tumbling},\n\tUrl = {http://scitation.aip.org/content/sor/journal/jor2/34/6/10.1122/1.550151},\n\tVolume = {34},\n\tYear = {1990},\n\tBdsk-Url-1 = {http://scitation.aip.org/content/sor/journal/jor2/34/6/10.1122/1.550151},\n\tBdsk-Url-2 = {http://dx.doi.org/10.1122/1.550151}}\n\n

The mechanical methods involved both shear and first normal stress measurements, and the optical experiments employed conservative linear dichroism. The experimental protocol used transient simple shear flows where the shear rate was either suddenly reversed in sign or stepped up to a higher value. In either case, pronounced oscillations of the same period were observed in both the mechanical and optical measurements. The periods, if measured in strain units, were observed to be independent of strain rate and suggested a suspension-like behavior. Since the conservative linear dichroism can be identified with the polarization-dependent scattering of light by the defect structure in the samples, these results offer strong evidence that this structure dominates the rheological response. textcopyright 1989 American Chemical Society.},\n\tAuthor = {Moldenaers, P and Fuller, G and Mewis, J},\n\tJournal = {Macromolecules},\n\tNumber = {2},\n\tPages = {960--965},\n\tTitle = {Mechanical and optical rheometry of polymer liquid-crystal domain structure},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0024607559&partnerID=40&md5=8e323e39cf43401996b2f7a16aacc3ab},\n\tVolume = {22},\n\tYear = {1989},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0024607559&partnerID=40&md5=8e323e39cf43401996b2f7a16aacc3ab}}\n\n

@article{johnson_optical_1988,\n\tAbstract = {Simultaneous linear dichroism and linear birefringence measurements were used to study sheared suspensions of colloidal hematite (α-Fe2O3) particles. Particles of three different axis ratios were synthesized. The particles were characterized using electron microscopy, and the three samples had axis ratios of 2.6 textpm 0.14, 3.61 textpm 0.24, and 5.82 textpm 0.58 with mean lengths of 0.315, 0.360, and 0.485 μm, repsectively. The particles were suspended in two Newtonian fluids, glycerin (viscosity = 17 P) and low molecular weight polybutene (viscosity = 220 P), and each suspension was subjected to transient shear flow in a Couette flow cell. The role of polydispersity in particle size on the relative orientations of the real and imaginary parts of the refractive index tensor was examined. It was demonstrated that when polydispersity in particle size exists, an asymmetric orienting field such as a simple shear flow generally results in birefringence and dichroism that are not coaxial. It was also found that at a wavelength of 632.8 nm, the particles can be adequately modeled as Rayleigh scatterers, and absorption can be neglected. textcopyright 1988.},\n\tAuthor = {Johnson, S J and Fuller, G.G.},\n\tJournal = {Journal of Colloid and Interface Science},\n\tNumber = {2},\n\tPages = {441--451},\n\tTitle = {The optical anisotropy of sheared hematite suspensions},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0024067675&partnerID=40&md5=2f30b6e13022fd684648b029ed824ed4},\n\tVolume = {124},\n\tYear = {1988},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0024067675&partnerID=40&md5=2f30b6e13022fd684648b029ed824ed4}}\n\n

@article{wagner_dichroism_1988,\n\tAbstract = {Optical measurements were used to detect structural anisotropy in concentrated dispersions over a range of Peclet numbers. Silica spheres of 49 and 130 run radii with grafted octadecyl chains were dispersed in cyclohexane at volume fractions from 0.1 to 0.4. The apparatus consisted of a Couette cell with the dispersion in the annulus probed by a HeNe laser beam parallel to the axis of rotation. The dichroism and birefringence of the transmitted beam varied linearly with shear rate at low Peclet numbers with an orientation coincident with the principle direction of shear. Increasing the Peclet number, by increasing the particle size, produced a nonlinear response with the orientation tending to align in the direction of flow. A theory coupling the nonequilibrium microstructure under shear to the optical properties of the suspension enables direct interpretation of the dichroism. Comparison of sample dichroism calculations for two different forms of the theory demonstrates that the optical technique can be used to discriminate between theories which predict the microstructure. textcopyright 1988 American Institute of Physics.},\n\tAuthor = {Wagner, N J and Fuller, G.G. and Russel, W B},\n\tJournal = {The Journal of Chemical Physics},\n\tNumber = {3},\n\tPages = {1580--1587},\n\tTitle = {The dichroism and birefringence of a hard-sphere suspension under shear},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0000900567&partnerID=40&md5=b7cb0a1a9e9246396dff3a8aa97d41a9},\n\tVolume = {89},\n\tYear = {1988},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0000900567&partnerID=40&md5=b7cb0a1a9e9246396dff3a8aa97d41a9}}\n\n

Data are reported for dilute suspensions of spheroidal haematite (α-Fe2O3) particles in both a Newtonian and a non-Newtonian Boger fluid consisting of 1000 ppm poly-isobutylene in low-molecular-weight polybutene. Haematite samples with average axis ratios of 2.66, 3.61 and 5.82 were used in the studies. Flow reversal and flow start-up experiments were conducted for shear rates up to 10 s-1 using both Couette and parallel-plate flow devices. The experimental data for suspensions in the non-Newtonian fluid are in qualitative agreement with predictions from the theory for particle motion in a second-order fluid. The particles experienced orbit drift and tended toward alignment along the vorticity axis of the flow. Also the period of rotation of the particles relative to that in the Newtonian suspending fluid increased with increasing shear rate. The predictions do not explicitly account for particle geometry, so experimental trends with axis ratio cannot be compared directly with the theory. In addition, Brownian motion is not considered by the theory, and we expect that the presence of Brownian motion in our suspensions strongly contributed to the steady-state distribution of particle orientation.},\n\tAuthor = {Johnson, S J and Fuller, G.G.},\n\tJournal = {Faraday Discussions of the Chemical Society},\n\tPages = {271--285},\n\tTitle = {The dynamics of colloidal particles suspended in a second-order fluid},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-37049078080&partnerID=40&md5=72e9edbc870b1b6e05a1c4530d3c246b},\n\tVolume = {83},\n\tYear = {1987},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-37049078080&partnerID=40&md5=72e9edbc870b1b6e05a1c4530d3c246b}}\n\n

In this paper, we compare the abilities of the Rayleigh and Rayleigh-Gans light scattering approximations to represent experimental dichroism data in terms of calculations based on known hydrodynamic models. In particular, the importance of considering finite particle size in the light scattering theory is investigated. Calculations of the conservative linear dichroism and of the average particle orientation angle are carried out for dilute suspensions subjected to transient simple shear flow in the absence of Brownian motion and in the presence of weak Brownian motion. For both situations, only small differences in the features associated with the particle orientation statistics of the simulation occur between the Rayleigh and the Rayleigh-Gans calculations over a wide range in particle geometry. In particular, the calculation of the average particle orientation angle is found to be insensitive to the choice of light scattering treatment. Generally, we infer from these simulations that the additional complexity of the Rayleigh-Gans treatment is usually not warranted for the analysis of typical rheo-optical data from dilute suspensions. textcopyright 1987.},\n\tAuthor = {Frattini, P L and Fuller, G.G.},\n\tJournal = {Journal of Colloid and Interface Science},\n\tNumber = {2},\n\tPages = {335--351},\n\tTitle = {Conservative dichroism of a sheared suspension in the {Rayleigh}-{Gans} light scattering approximation},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0023437432&partnerID=40&md5=ca97301fd07acde13a313e0d64de41c8},\n\tVolume = {119},\n\tYear = {1987},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0023437432&partnerID=40&md5=ca97301fd07acde13a313e0d64de41c8}}\n\n

The dichroism provides a direct measure of the particle dynamics, but the birefringence is a composite property with independent contributions from the suspended particles and the polymer molecules. For suspensions where the contribution from the particles is significant, the composite birefringence must be decoupled in order to analyze the dynamics of the polymeric suspending fluid. A method to perform the decoupling is derived and then demonstrated through transient shear flow experiments with dilute suspensions of βFeOOH particles in semi-dilute, xanthan gum suspending fluids. The birefringence of the xanthan gum suspending fluid is calculated from experimental measurements of the composite birefringence and the dichroism of the suspension. To gather information on particle/polymer interactions, the calculated birefringence is compared to the birefringence of xanthan gum solutions containing no suspended particles and the dirchoism is compared to that of a suspension in a Newtonian fluid. textcopyright 1986 Steinkopff.},\n\tAuthor = {Johnson, S J and Fuller, G.G.},\n\tJournal = {Rheologica Acta},\n\tNumber = {4},\n\tPages = {405--417},\n\tTitle = {Flowing colloidal suspensions in non-{Newtonian} suspending fluids: {Decoupling} the composite birefringence},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0006654099&partnerID=40&md5=1beb2710a50a79820207fb2ee33dac38},\n\tVolume = {25},\n\tYear = {1986},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0006654099&partnerID=40&md5=1beb2710a50a79820207fb2ee33dac38}}\n\n

For dilute suspensions of absorbing particles which are larger than the wavelength of the incident light, scalar diffraction theory is applied to relate the moments of the measured pattern to the degree of alignment and average orientation angle of the particles. The diffraction pattern for non-Brownian, near-sphere particles in Stokes flow is solved and shows an oscillation between isotropic contours, when the particles are randomly oriented, and elliptical contours oriented perpendicular to the average orientation of the particles. Experimental results for the inception and reversal of simple shear flow of a dilute suspension of prolate ellipsoids in a parallel plate device are presented and exhibit this behavior.

@article{zebrowski_rheo-optical_1985,\n\tAbstract = {Concentrated polystyrene solutions were investigated on the inception and cessation of simple shear flow by means of the technique of two-color flow birefringence. Both monodisperse solutions of various molecular weights and biomodal mixtures were studied. The molecular weight affected both the amount of overshoot in the birefringence and the response time on the inception of shear flow. Large overshoots in birefringence, up to 250\\%, and undershoot in the orientation angle were observed. The shear stress and the first normal stress difference were calculated by using the stress-optical rule. The amount of strain at the peaks in the stress growth curves are presented along with the steady-state viscosity and primary normal stress coefficient. The experimental results are compared qualitatively with theoretical predictions of various molecular models.},\n\tAuthor = {Zebrowski, Beth E and Fuller, Gerald G},\n\tJournal = {Journal of polymer science.

@article{johnson_simultaneous_1985,\n\tAbstract = {A new experimental technique is presented for the study of the dynamics of dilute colloidal suspensions in transient shear flow. Based on the polarization modulation of light, the experiment permits simultaneous determinations of linear dichroism (Δntextacutedbl), linear birefringence (Δntextasciiacute), the orientation angle of the principal axis of Δntextacutedbl, and the orientation angle of the principal axis of Δntextasciiacute. All four calculated quantities are functions of time in transient flow situations. A detailed mathematical analysis of the experiment is presented, and six limiting cases of the general mathematical results are derived. To demonstrate the experimental technique, a 400 ppm suspension of ferric hydrous oxide (βFeOOH) particles in 97\\% glycerine and 3\\% water was subjected to transient, simple shear flow in a Couette flow cell. The βFeOOH suspension represents the limiting case of very small Δntextacutedbl and Δntextasciiacute which allows a clear demonstration of the experimental method. Magnitudes of 10 -7 for both Δntextacutedbl and Δntextasciiacute were measured experimentally at shear rates of 4, 8, and 24 sec -1 in flow reversal sequences. In addition, Δntextacutedbl and Δntextasciiacute were found to be coaxial. Simultaneous dichroism and birefringence measurements provide a means of studying the dynamics of suspensions in non-Newtonian suspending fluids. The application of this experimental method to the study of particles suspended in non-Newtonian, polymer fluids is discussed. textcopyright 1985.},\n\tAuthor = {Johnson, S J and Frattini, P L and Fuller, G.G.},\n\tJournal = {Journal of Colloid and Interface Science},\n\tNumber = {2},\n\tPages = {440--455},\n\tTitle = {Simultaneous dichroism and birefringence measurements of dilute colloidal suspensions in transient shear flow},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0022042704&partnerID=40&md5=9280063200612b78c3a21e734222731f},\n\tVolume = {104},\n\tYear = {1985},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0022042704&partnerID=40&md5=9280063200612b78c3a21e734222731f}}\n\n

@article{park_dynamics_1984,\n\tAbstract = {This paper describes exact solutions to the response of both the elastic and rigid dumbbell models to a steady simple shear flow in a channel having a length scale comparable to the dumbbells themselves. Results are given for rheological properties over the entire range of the ratio of the channel width to the length of the dumbbell. It is found that both models lead to a decrease in viscosity as the channel is reduced in size with the elastic dumbbell predicting a stronger dependence on that parameter compared with the rigid dumbbell. The elastic dumbbell predicts shear independent rheological properties whereas the rigid dumbell predicts shear thinning as in the case of unbounded flows. The rate of shear thinning, however, decreases with decreasing channel width.},\n\tAuthor = {Park, O Ok and Fuller, Gerald G},\n\tDoi = {10.1016/0377-0257(84)80016-6},\n\tJournal = {Journal of Non-Newtonian Fluid Mechanics},\n\tLanguage = {English},\n\tMonth = jan,\n\tNumber = {3},\n\tPages = {309--329},\n\tTitle = {Dynamics of rigid and flexible polymer chains in confined geometries. part {I}: steady simple shear flow},\n\tUrl = {http://linkinghub.elsevier.com/retrieve/pii/0377025784800166},\n\tVolume = {15},\n\tYear = {1984},\n\tBdsk-Url-1 = {http://linkinghub.elsevier.com/retrieve/pii/0377025784800166},\n\tBdsk-Url-2 = {http://dx.doi.org/10.1016/0377-0257(84)80016-6}}\n\n

@article{frattini_dynamics_1984,\n\tAbstract = {An apparatus is described which permits simultaneous determination of the conservative linear dichroism and the average orientation angle of a dilute suspension of optically anisotropic, nonabsorbing spheroids subjected to a transient shear field. The magnitude of the dichroism reflects the degree of alignment of the particles along their average orientation angle and measurement of this property in time directly obtains the rotational motion of the particles. This experiment makes use of a photoelastic modulator in a novel optical train; the first and second harmonics of the detector signal, which are independent functions of the dichroism and orientation angle, are measured simultaneously as functions of time. Preliminary data on a dilute suspension of bentonite in 90\\% glycerine and 10\\% water subjected to an instantaneous simple shear are presented to illustrate the technique. The qualitative features of these data are adequately described by the Rayleigh scattering theory coupled with Jeffery's solution for the dynamics of a rigid spheroid in a creeping simple shear. textcopyright 1984 Academic Press, Inc.

No detectable changes in film thickness were observed for the three lower molecular weight samples over the whole range of velocity gradients applied. On the other hand, the film thickness of the 20 million molecular weight sample began to decrease as the apparent velocity gradient surpassed 2000 s-1 and decreased as much as 15\\% when the apparent velocity gradient reached 7800 s-1. The response of the adsorbed polymer layer to the imposition of the flow over short periods of time was reversible, and no change in adsorbance was observed between the inception and cessation of the flow. The measured conformational changes were also compared to the predictions of a simple bead-and-spring model of an attached polymer segment, and qualitative agreement was obtained when the effect of finite extensibility was included in the model. textcopyright 1984 American Chemical Society.},\n\tAuthor = {Lee, J J and Fuller, G.G.},\n\tJournal = {Macromolecules},\n\tNumber = {3},\n\tPages = {375--380},\n\tTitle = {Ellipsometry studies of adsorbed polymer chains subjected to flow},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0000347373&partnerID=40&md5=36f58782fb47d07c8142b2aee525e2b8},\n\tVolume = {17},\n\tYear = {1984},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0000347373&partnerID=40&md5=36f58782fb47d07c8142b2aee525e2b8}}\n\n

@article{fuller_effects_1981,\n\tAbstract = {The effects of a nonlinear spring, variable hydrodynamic friction and internal viscosity are examined in detail for the dumbbell model of dilute polymer solutions in a general two-dimensional flow. Both steady and transient startup flows are investigated and the response of the bulk stress is calculated. The existence of a hysteresis in the steady end-to-end length of the dumbbell, which arises from the variable friction factor, is found to depend strongly on both the flow type (i.e. the ratio of vorticity to the rate of strain) and the moleculecular weight. The influence of internal viscosity is examined in detail using two methods of solution for the problems of transient and steady two-dimensional flows. The first method uses a perturbation expansion valid for small values of the internal viscosity and leads largely to analytical results. The second technique uses the pre-averaging approximation of Cerf and is capable of predicting the model response when the internal viscosity becomes large. The most striking result for large values of the internal viscosity and a linear spring dumbbell is the appearance of multiple steady states in the dumbbell length for flows between simple shear and pure straining, and the removal of the well known singularity in end-to-end length which otherwise appears in the linear dumbbell model at a critical value of the strain rate. textcopyright 1981.},\n\tAuthor = {Fuller, G.G. and Leal, L G},\n\tJournal = {Journal of Non-Newtonian Fluid Mechanics},\n\tNumber = {3-4},\n\tPages = {271--310},\n\tTitle = {The effects of conformation-dependent friction and internal viscosity on the dynamics of the nonlinear dumbbell model for a dilute polymer solution},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0019592088&partnerID=40&md5=613ff817e6ff1267f59fca9d70da6f13},\n\tVolume = {8},\n\tYear = {1981},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0019592088&partnerID=40&md5=613ff817e6ff1267f59fca9d70da6f13}}\n\n

@article{fuller_flow_1980,\n\tAbstract = {Flow birefringence measurements have been obtained on three molecular weight samples (2-8 texttimes 106MW, MW/MN = 1.14-1.3) of polystyrene in dilute solution (50-100 ppm) in a viscous polychorinated biphenyl solvent. The flows were generated using a four roll mill which could simulate a wide range of two dimensional flows in which the flow type (i.e. the ratio of the rate of rotation to the rate of strain) could be varied independently of the velocity gradient. The normalized birefringence, corrected for concentration, (Δn/nc), was observed to approach a saturation value at high velocity gradients in purely extensional flow. This saturation value was independent of both the molecular weight and the concentration c, in agreement with theory. In addition, the magnitude of the saturation value is consistent with nearly fully extended chains and suggests extensions in the range of 20-50 times the rest state size. The data for the birefringence over a wide range of flows was found to be well correlated against the eigenvalue of the velocity gradient tensor in agreement with the results of the "strong/weak" flow theories of Tanner (1976) and Olbricht et al. (1980). The experiments are compared with a simple dumbbell model which incorporates the effects of a nonlinear spring variable hydrodynamic friction, and internal viscosity. It is shown that this simple model can simulate the experimental results surprisingly well if the effects of molecular weight distribution and finite transit times in the flow device are taken into account. textcopyright 1980 Dr. Dietrich Steinkopff Verlag.},\n\tAuthor = {Fuller, G.G. and Leal, L G},\n\tJournal = {Rheologica Acta},\n\tNumber = {5},\n\tPages = {580--600},\n\tTitle = {Flow birefringence of dilute polymer solutions in two-dimensional flows},\n\tUrl = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0000485304&partnerID=40&md5=0594fccdd3cb1415a4145f4a36c17f9a},\n\tVolume = {19},\n\tYear = {1980},\n\tBdsk-Url-1 = {http://www.scopus.com/inward/record.url?eid=2-s2.0-0000485304&partnerID=40&md5=0594fccdd3cb1415a4145f4a36c17f9a}}\n\n

@article{paul_applications_1976,\n\tAbstract = {Starting from a finite temperature Green's function formalism we have developed a diagrammatic method for calculating the complex dielectric constant of a system consisting of diatomic molecules that are strongly interacting with the solvent medium. Perturbative treatments suitable for weak interactions have been replaced by a variational method, and diagrams picked up are summed up to all orders in the solvent-solute interaction potential. A method is presented whereby all the vectorial integrations can be carried out exactly leaving a final quadrature which must be done numerically. It is pointed out that the internal states of the diatomic molecule are coupled to each other via a very complicated cooperative effect induced by the solvent.},\n\tAuthor = {Paul, R and Fuller, G.G.},\n\tDoi = {10.1063/1.432699},\n\tJournal = {Journal of Chemical Physics},\n\tNumber = {9},\n\tPages = {3809--3825},\n\tTitle = {Applications of field theoretical methods to the calculation of infrared band shapes of molecules in strongly interacting solvents. {I}.},\n\tUrl = {http://adsabs.harvard.edu/cgi-bin/nph-data_query?bibcode=1976JChPh..64.3809P&link_type=EJOURNAL},\n\tVolume = {64},\n\tYear = {1976},\n\tBdsk-Url-1 = {http://adsabs.harvard.edu/cgi-bin/nph-data_query?bibcode=1976JChPh..64.3809P&link_type=EJOURNAL},\n\tBdsk-Url-2 = {http://dx.doi.org/10.1063/1.432699}}\n\n

@article{fuller_modified_1976,\n\tAbstract = {The modified form of the Redlich-Kwong equation of statees with greater accuracy. The additional modifications contain two features; first, the equation of state now leads to a variable critical co proposed by Soave is further generalized in order to reproduce saturated liquid volumes and compressed liquid volumes of pure substancmpressibility factor, and second, a new universal temperature function is incorporated in the equation making both the a and b parameters functions of temperature. The added modifications preserve the ability of the equation to predict vapor pressures with only the critical volume and parachor being required as additional data input. The results of calculations indicate that the proposed equation is capable of describing even polar molecules such as water and ammonia with reasonable accuracy.},\n\tAuthor = {Fuller, G.G.},\n\tJournal = {Ind.
