These models belong to the class of the spherical mean-field approximation of a spin-1 model with p-body quenched disordered interaction, with p>2, termed spherical Blume-Emery-Griffiths models. Depending on temperature and chemical potential the system is found in a paramagnetic or in a glassy phase and the transition between these phases can be of a different nature. In specific regions of the phase diagram coexistence of low-density and high-density paramagnets can occur, as well as the coexistence of spin-glass and paramagnetic phases. The exact static solution for the glassy phase is known to be obtained by the one-step replica symmetry breaking ansatz. Different scenarios arise for both the dynamic and the thermodynamic transitions. These include: (i) the usual random first-order transition (Kauzmann-like) for mean-field glasses preceded by a dynamic transition, (ii) a thermodynamic first-order transition with phase coexistence and latent heat, and (iii) a regime of apparent inversion of static transition line and dynamic transition lines, the latter defined as a nonzero complexity line. The latter inversion, though, turns out to be preceded by a dynamical arrest line at higher temperature. Crossover between different regimes is analyzed by solving mode-coupling-theory equations near the boundaries of paramagnetic solutions and the relationship with the underlying statics is discussed. © 2015 American Physical Society.},\npublisher={American Physical Society},\nissn={15393755},\ncoden={PLEEE},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

In this work, novel hybrid organic fibers that can effectively report the analyte concentration within the local microenvironment are reported. The nanostructured and flexible wires are prepared by embedding fluorescent pH sensors based on seminaphtho-rhodafluor-1-dextran conjugate. By adjusting capsule/polymer ratio and spinning conditions, the diameter of the fibers and the alignment of the reporting capsules are both tuned. The hybrid wires display excellent stability, high sensitivity, as well as reversible response, and their operation relies on effective diffusional kinetic coupling of the sensing regions and the embedding polymer matrix. These devices are believed to be a powerful new sensing platform for clinical diagnostics, bioassays and environmental monitoring. Novel pH-sensing organic fibers are prepared by capsule-based sensors. Appropriate choice of capsule loading during electrospinning ensures alignment within the fibers, leading to pH-sensing devices with excellent stability, high sensitivity, μm-spatial resolution as well as reversible response to proton switches. These results show a promising strategy for the development of sensitive and robust self-reporting fiber-optic sensors for bioassays and environmental monitoring. © 2015 The Authors.

We have evaluated the energetics of H-abstraction reaction from methane within the (0. 1. 0) straight channel of acidic zeolite by different computational approaches. First by in bulk plane waves Density Functional Theory (with and without dispersion energy correction) and then, in gas-phase cluster, by typical quantum chemistry approaches based on molecular orbital theory, where electronic wave function is expanded in Gaussian basis sets, within variational or perturbative schemes. Reaction paths have been determined either by Climbing Image Nudged Elastic Band method (c-NEB) in bulk or by Intrinsic Reaction Coordinate (IRC) method in gas phase.

In their condensed form, they display quantum hydrodynamic features similar to atomic Bose-Einstein condensates, such as long-range coherence, superfluidity and quantized vorticity. Here we report the unique phenomenology that is observed when a pulse of light impacts the polariton vacuum: the fluid which is suddenly created does not splash but instead coheres into a very bright spot. The real-space collapse into a sharp peak is at odd with the repulsive interactions of polaritons and their positive mass, suggesting that an unconventional mechanism is at play. Our modelling devises a possible explanation in the self-trapping due to a local heating of the crystal lattice, that can be described as a collective polaron formed by a polariton condensate. These observations hint at the polariton fluid dynamics in conditions of extreme intensities and ultrafast times.},\npublisher={Nature Publishing Group},\nissn={20411723},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Their appearance is connected with spontaneous symmetry breaking and phase transitions. In Bose-Einstein condensates and superfluids, vortices are both point-like and quantized quasiparticles. We use a two-dimensional (2D) fluid of polaritons, bosonic particles constituted by hybrid photonic and electronic oscillations, to study quantum vortex dynamics. Polaritons benefit from easiness of wave function phase detection, a spinor nature sustaining half-integer vorticity, strong nonlinearity, and tuning of the background disorder. We can directly generate by resonant pulsed excitations a polariton condensate carrying either a full or half-integer vortex as initial condition and follow their coherent evolution using ultrafast imaging on the picosecond scale. The observations highlight a rich phenomenology, such as the spiraling of the half-vortex and the joint path of the twin charges of a full vortex, until the moment of their splitting. Furthermore, we observe the ordered branching into newly generated secondary couples, associatedwith the breaking of radial and azimuthal symmetries. This allows us to devise the interplay of nonlinearity and sample disorder in shaping the fluid and driving the vortex dynamics. In addition, our observations suggest that phase singularitiesmay be seen as fundamental particles whose quantized events span from pair creation and recombination to 2D+t topological vortex strings. © 2015 The Authors, some rights reserved; exclusive licensee American Association for the Advancement of Science.},\npublisher={American Association for the Advancement of Science},\nissn={23752548},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Finally, a comparison between the electrical resistances measured on these samples versus the pulse number and the inverse current density calculated as a function of the number of ND particles, showed a good agreement. The experimental results highlighted an increase of the electrical current by using a number of pulses &lt;100, whereas the simulation results proved the enhancement of current density and its surface rectification by employing a specific number of particles. The current increased by increasing the temperature and during the heating-cooling cycles hysteresis was observed.

From an initial large-scale velocity shear, the nonlinear evolution of the instability leads to the formation of a region inside the initial vortex characterized by small-scale fluctuations and structures. The magnetic energy spectrum is compatible with a Kolmogorov-like power-law decay, followed by a steeper power-law below proton scales, in agreement with other studies. The magnetic field increments show non-Gaussian distributions with increasing tails going towards smaller scales, consistent with presence of intermittency. The strong magnetic field fluctuations populating the tails of the distributions have been identified as current sheets by using the Partial Variance of the Increments (PVI) method. The strongest current sheets (largest PVI) appear around proton scales and below. By selecting several of such current sheets, it has been found that most of them are consistent with ongoing magnetic reconnection. The detailed study of one reconnecting current sheet as crossed by a virtual spacecraft is also presented. Inflow and outflow regions have been identified and the reconnection rate has been estimated. The observation of reconnection rates higher than typical fast rate ∼0.1 suggests that reconnection in turbulent plasma can be faster than laminar reconnection. This study indicates that intermittency and reconnecting current sheets are important ingredients of turbulence within Kelvin-Helmholtz vortices and that reconnection can play an important role for energy dissipation therein. © 2015 AIP Publishing LLC.},\npublisher={American Institute of Physics Inc.},\nissn={1070664X},\ncoden={PHPAE},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

This order parameter allows to identify the laser transition in random media and describes its possible glassy nature in terms of emission spectra data, the only data so far accessible in random laser measurements. The theoretical analysis is performed in terms of the complex spherical spin-glass model, a statistical mechanical model describing the onset and the behavior of random lasers in open cavities. Replica Symmetry Breaking theory allows to discern different kinds of randomness in the high pumping regime, including the most complex and intriguing glassy randomness. The outcome of the theoretical study is, eventually, compared to recent intensity fluctuation overlap measurements demonstrating the validity of the theory and providing a straightforward interpretation of qualitatively different spectral behaviors in different random lasers.},\npublisher={Nature Publishing Group},\nissn={20452322},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

The superposition of the oscillating fields result in the precession of the Stokes vector of the emitted light while polariton lifetime imbalance results in its drift from a circle of controllable radius on the Poincaré sphere to a single point at long times. The positioning of the initial circle and final point allows to engineer the type of polarization spanning, including a full sweeping of the Poincaré sphere.

We combined spectrophotometry, Raman spectroscopy, and grazing incidence small-angle X-ray scattering with calculations of dipole coupling models and soft sphere interactions. We demonstrate that dense arrays of elementary edge dislocations can strongly localize small NPs along the defect cores, resulting in formation of parallel chains of NPs. Furthermore, we show that within the dislocation cores the inter-NP distances can be tuned. This phenomenon appears to be driven by the competition between "soft (nano)sphere" attraction and LC-induced repulsion. We evidence two extreme regimes controlled by the solvent evaporation: (i) when the solvent evaporates abruptly, the spacing between neighboring NPs in the chains is dominated by van der Waals interactions between interdigitated capping ligands, leading to chains of close-packed NPs; (ii) when the solvent evaporates slowly, strong interdigitation between the is avoided, leading to a dominating LC-induced repulsion between NPs associated with the replacement of disordered cores by NPs. The templating of NPs by topological defects, beyond the technological inquiries, may enable creation, investigation, and manipulation of unique collective features for a wide range of nanomaterials. © 2015 American Chemical Society.},\npublisher={American Chemical Society},\nissn={19360851},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

In order to detect the intense bursts of high kinetic energy electrons generated by the X-ray pulses with an energy resolution comparable to the existing category of electron analyzers, a new class of spectrometers must be designed. We present a characterization of two different TOF spectrometers, namely one based on a retarding cylindrical lens and another one based on the spherical reflector geometry. SIMION® software has been used in order to evaluate electron trajectories of high kinetic energy electrons (5000-10,000 eV) and extract transmission properties, angular acceptance and energy resolution. It resulted that while the linear system is able to accept a larger solid angle (∼50 msr), the spherical mirror offers a better resolving power (around 71,000). Both analyzers are capable of a transmission above 90% within range of kinetic energies wide enough to measure the full line-shape of a core photoionization peak. Furthermore, we proved that both instruments are able to discriminate between two consecutive electron bunches having a temporal separation inferior than 220 ns, which is the distance between two consecutive photon pulses at the European X-ray Free Electron Laser (EXFEL), which is currently under construction in Hamburg. © 2015 Elsevier B.V.},\npublisher={Elsevier},\nissn={03682048},\ncoden={JESRA},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

One popular method to promote resist adhesion is to modify the substrate surface. In this study, the authors will show that a poly(methylmethacrylate-co-methacrylic acid) [P(MMA-co-MAA)] monolayer "brush" can be grafted onto a silicon substrate using thermal annealing that leads to chemical bonding of the P(MMA-co-MAA) copolymer to the hydroxyl group-terminated substrate, followed by acetic acid wash to remove the bulk, unbonded copolymer. The monolayer brush has a thickness of 12 nm. The authors will show that it can greatly improve the adhesion of positive resist, the ZEP-520A, and negative resist polystyrene to bare silicon surfaces, which led to high resolution patterning without resist detachment upon development. The improvement was more dramatic when patterning dense sub-100 nm period grating structures. But the improvement was negligible for an aluminum substrate, because, even without the brush layer, resist adhesion to aluminum is found already to be strong enough to prevent resist structure peeling off. The current simple and low cost method could be very useful when resist adhesion to the substrate for a given developer is weak. © 2015 American Vacuum Society.},\npublisher={American Institute of Physics Inc.},\nissn={21662746},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Notwithstanding this obstacle, the Asian green mussel Perna viridis attaches firmly to underwater surfaces via a proteinaceous secretion (byssus). Extending beyond the currently known design principles of mussel adhesion, here we elucidate the precise time-regulated secretion of P. viridis mussel adhesive proteins. The vanguard 3,4-dihydroxy-L-phenylalanine (Dopa)-rich protein Pvfp-5 acts as an adhesive primer, overcoming repulsive hydration forces by displacing surface-bound water and generating strong surface adhesion. Using homology modelling and molecular dynamics simulations, we find that all mussel adhesive proteins are largely unordered, with Pvfp-5 adopting a disordered structure and elongated conformation whereby all Dopa residues reside on the protein surface. Time-regulated secretion and structural disorder of mussel adhesive proteins appear essential for optimizing extended nonspecific surface interactions and byssus assembly. Our findings reveal molecular-scale principles to help the development of wet-resistant adhesives. © 2015 Macmillan Publishers Limited.

The advantages of the resulting construction are many. The first one is that it gives a quasi equilibrium description on how glassy systems explore the phase space in the slow relaxation part of their dynamics. The second one is that it gives an alternative way to obtain dynamical equations starting from a dynamical rule that is static in spirit. This provides a way to overcome the difficulties encountered in the short time part of the dynamics where current conservation must be enforced. We study this approach in detail in a prototypical mean field disordered spin system, namely the p-spin spherical model, showing how we can obtain the well known equations that describe its dynamics. Then we apply the same approach to structural glasses. We first derive a set of dynamical Ornstein- Zernike equations which are very general in nature. Finally we consider two possible closure schemes for them, namely the hypernetted chain approximation of liquid theory and a closure of the BBGKY hierarchy that has been recently introduced by Szamel. From both approaches we finally find a set of dynamical mode-coupling-like equations that are supposed to describe the system in the long time/slow dynamics regime. ï¿½ 2015 IOP Publishing Ltd and SISSA Medialab srl.},\npublisher={Institute of Physics Publishing},\nissn={17425468},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

We show that metal oxidation can sensibly affect the plexcitonic system, inducing a change in the coupling strength. In particular, we demonstrate that the presence of oxide prevents the appearance of Rabi splitting in the extinction spectra for thick spacers. In contrast, below a threshold percentage, the oxide layer results in an higher coupling strength between the plasmon and the Frenkel exciton. Contrary to common belief, a thin oxide layer seems thus to act, under certain conditions, as a coupling mediator between an emitter and a localized surface plasmon excited in a metallic nanostructure. This suggests that metal oxidation can be exploited as a means to enhance light-matter interactions in strong coupling applications. © 2015 American Chemical Society.},\npublisher={American Chemical Society},\nissn={19360851},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

We use this method to characterize the band-edge exciton fine structure splitting of various samples of dot-in-rods. We show that, when the diameter of the CdSe core increases, a transition from a spherical like band-edge exciton symmetry to a rod-like band edge exciton symmetry occurs.

In this regard, diamond-like carbon (DLC) coatings on cotton fabrics may represent promising candidates as potential flame-retardant (FR) materials. Herein, superhydrophobic and fire-resistant cotton fabrics were fabricated through a two-step plasma strategy by alternately exposing substrates to H<inf>2</inf> and O<inf>2</inf> plasma pre-treatments and subsequent DLC deposition. Fourier transform-infrared spectroscopy analysis has revealed that different plasma pre-treatments can impose surface modifications on the chemical structure of cotton, especially in carboxylic and hydroxyl groups, leading to a radical alteration of surface roughness and of the crystalline cellulosic external structure. These changes deeply influenced the growth of DLC thin films and the surface properties of cotton fabric because of the combination of a hierarchical structure and surface chemistry as verified using field emission gun-scanning electron microscopy and water contact angle measurements. The effects of both specific gases used in the pre-treatment step and duration of pre-treatment were analysed and compared using thermogravimetric analyses. The H<inf>2</inf>-pre-treated DLC cottons exhibited good potential as an FR material, showing improved thermal stability in respect to untreated cotton, as evidenced by increased ignition times. Moreover, vertical burning tests have demonstrated that DLC-cotton systems exhibit enhanced flammability resistance. © 2015, Springer Science+Business Media Dordrecht.},\npublisher={Kluwer Academic Publishers},\nissn={09690239},\ncoden={CELLE},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Light-to-work conversion can involve either direct transfer of optical momentum or indirect opto-thermal effects. Both strategies have been implemented using different coupling mechanisms. However, the resulting efficiencies are always very low, and high power densities, generally obtained by focused laser beams, are required. Here we show that microfabricated gears, sitting on a liquid-air interface, can efficiently convert absorbed light into rotational motion through a thermocapillary effect. We demonstrate rotation rates up to 300r.p.m. under wide-field illumination with incoherent light. Our analysis shows that thermocapillary propulsion is one of the strongest mechanisms for light actuation at the micron- and nanoscale.},\npublisher={Nature Publishing Group},\nissn={20411723},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

In equilibrium systems such as liquid 4He and ultracold atomic gases, superfluid behavior conjugates diverse yet related phenomena, such as a persistent metastable flow in multiply connected geometries and the existence of a critical velocity for frictionless flow when hitting a static defect. The link between these different aspects of superfluid behavior is far less clear in driven-dissipative systems displaying collective coherence, such as microcavity polaritons, which raises important questions about their concurrency. With a joint theoretical and experimental study, we show that the scenario is particularly rich for polaritons driven in a three-fluid collective coherent regime, i.e., a so-called optical parametric oscillator. On the one hand, the spontaneous macroscopic coherence following the phase locking of the signal and idler fluids has been shown to be responsible for their simultaneous quantized flow metastability. On the other hand, we show here that the pump, signal, and idler have distinct responses when hitting a static defect; while the signal displays modulations that are barely perceptible, the ones appearing in the pump and idler are determined by their mutual coupling due to nonlinear and parametric processes. © 2015 American Physical Society. ©2015 American Physical Society.},\npublisher={American Physical Society},\nissn={10980121},\ncoden={PRBMD},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

When defined in dense topologies, these are effective models for the nonlinear interaction of scalar fields in the presence of a stochastic noise, as has been well established for the case of the mode-locking laser formation in a closed cavity. With the help of an efficient Monte Carlo algorithm we show how, beyond the fully connected case, rich phenomenology emerges. Below a certain dilution threshold, the spherical model condenses in a nonequipartite way, while in the XY model the transition becomes continuous and the O(2) symmetry remains unbroken. We attribute this fact to the invariance under gauge transformations. The introduction of topological inhomogeneities in the network of quadruplets induces some features: again symmetry conservation; the vanishing of two-point correlators; and a dynamical correlation function presenting two time scales, the large one being related to the transition between different degenerated configurations, connected by particular gauge transformations. We discuss possible experimental implications of these results in the context of nonlinear optics. © 2015 American Physical Society.},\npublisher={American Physical Society},\nissn={10980121},\ncoden={PRBMD},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

The comprehension of the operating principles of solar cells based on HCs thus represents a crucial step toward the rational engineering of high performing photovoltaic devices. Here we investigate the effect of conjugated polymers on hybrid solar cell performances by taking advantage from an optimized morphology of the HCs comprising lead sulfide quantum dots (PbS QDs). Uncommonly, we find that larger photocurrent densities are achieved by HCs incorporating wide-bandgap polymers. A combination of spectroscopic and electro-optical measurements suggests that wide-bandgap polymers promote efficient charge/exciton transfer processes and hinder the population of midgap states on PbS QDs. Our findings underline the key role of the polymer in HC-based solar cells in the activation/deactivation of charge transfer/loss pathways. © 2015 American Chemical Society.},\npublisher={American Chemical Society},\nissn={19327447},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

In many types of cancers this leads, even in the presence of oxygen, to the secretion of carbon equivalents (usually in the form of lactate) in the cell's surroundings, a feature known as the Warburg effect. While the molecular basis of this phenomenon are still to be elucidated, it is clear that the spilling of energy resources contributes to creating a peculiar microenvironment for tumors, possibly characterized by a degree of toxicity. This suggests that mechanisms for recycling the fermentation products (e.g. a lactate shuttle) may be active, effectively inducing a mutually beneficial metabolic coupling between aberrant and non-aberrant cells. Here we analyze this scenario through a large-scale in silico metabolic model of interacting human cells. By going beyond the cell-autonomous description, we show that elementary physico-chemical constraints indeed favor the establishment of such a coupling under very broad conditions. The characterization we obtained by tuning the aberrant cell's demand for ATP, amino-acids and fatty acids and/or the imbalance in nutrient partitioning provides quantitative support to the idea that synergistic multi-cell effects play a central role in cancer sustainment. © 2015, Nature Publishing Group.

By studying the swimming motion of Escherichia coli cells near microfabricated pillars of variable size, we show that cell entrapment is also present for convex walls of sufficiently low curvature. Entrapment is, however, markedly reduced below a characteristic radius. Using a simple hydrodynamic model, we predict that trapped cells swim at a finite angle with the wall and a precise relation exists between the swimming angle at a flat wall and the critical radius of curvature for entrapment. Both predictions are quantitatively verified by experimental data. Our results demonstrate that the main mechanism for wall entrapment is hydrodynamic in nature and show the possibility of inhibiting cell adhesion, and thus biofilm formation, using convex features of appropriate curvature. © 2015 American Physical Society.},\npublisher={American Physical Society},\nissn={00319007},\ncoden={PRLTA},\npubmed_id={26197146},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

In the run state all flagella join in a single helical bundle that propels the cell body along approximately straight paths. When one or more flagellar motors reverse direction the bundle unwinds and the cell randomizes its orientation. This basic picture represents an idealization of a much more complex dynamical problem. Although it has been shown that bundle formation can occur at either pole of the cell, it is still unclear whether these two run states correspond to asymmetric propulsion features. Using holographic microscopy we record the 3D motions of individual bacteria swimming in optical traps. We find that most cells possess two run states characterized by different propulsion forces, total torque, and bundle conformations. We analyze the statistical properties of bundle reversal and compare the hydrodynamic features of forward and backward running states. Our method is naturally multi-particle and opens up the way towards controlled hydrodynamic studies of interacting swimming cells. © 2015 American Physical Society.},\npublisher={American Physical Society},\nissn={15393755},\ncoden={PLEEE},\npubmed_id={26172734},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

In view of the therapeutic relevance of such plasmonic NPs, a detailed characterization of the electrostatic interaction between positively charged gold nanorods (GNRs) and a negatively charged whole-genome DNA solution is reported. The preparation of the hybrid biosystem has been investigated as a function of DNA concentration by means of ζ-potential, hydrodynamic diameter and gel electrophoresis analysis. The results have pointed out the specific conditions to achieve the most promising GNRs/DNA complex and its photo-thermal properties have been investigated.

Cu2+ and metal-free protein solutions showed a distinct exothermic response that disappeared almost completely when the Fe3+ molar concentration was ten times greater than the βLG concentration. Thioflavin T fluorescence studies in solution and atomic force microscopy analysis of the deposit left on flat mica substrates by heat-incubated βLG solutions correlated the absence of exothermic response of Fe3+-βLG solutions with a lack of fibril production. In contrast, abundant fibril deposits were observed for Cu2+-βLG solutions, with a rich polymorphism of multistrand fibrillar structures. Electron paramagnetic resonance revealed that Fe3+ permanently binds to βLG in the aggregate state whereas Cu2+ plays a catalytic role without binding to the protein. We propose that Fe3+ inhibits fibril production after binding to a key region of the protein sequence, possibly interfering with the nucleation step of the fibrillation process and opening a nonfibrillar aggregation pathway. These findings suggest that transition metal ions can be utilized to effectively modulate protein self-assembly into a variety of structures with distinct morphologies at the nanoscale level. © 2015 American Chemical Society.},\npublisher={American Chemical Society},\nissn={15257797},\ncoden={BOMAF},\npubmed_id={25989053},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

The model includes the dynamics of the mode intensity and accounts also for the possible presence of a linear coupling between the modes, due, e.g., to the leakages from an open cavity. The complete phase diagram, in terms of disorder strength, source pumping, and nonlinearity, consists of four different optical regimes: incoherent fluorescence, standard mode locking, random lasing, and the spontaneous phase locking. A replica symmetry-breaking phase transition is predicted at the random lasing threshold. For a high enough strength of nonlinearity, a whole region with nonvanishing complexity anticipates the transition, and the light modes in the disordered medium display typical discontinuous glassy behavior, i.e., the photonic glass has a multitude of metastable states that correspond to different mode-locking processes in random lasers. The lasing regime is still present for very open cavities, although the transition becomes continuous at the lasing threshold. © 2015 American Physical Society.},\npublisher={American Physical Society},\nissn={10502947},\ncoden={PLRAA},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Here we have analyzed CHNH3PbI 3-xClx in planar or in mesostructured (MS) configurations, employing both titania and alumina scaffolds, fully infiltrated with perovskite material or presenting an overstanding layer. The use of the MS scaffold induces to the perovskite different structural properties, in terms of grain size, preferential orientation, and unit cell volume, in comparison to the ones of the material grown with no constraints, as we have found out by X-ray diffraction analyses. We have studied the effect of the PSC configuration on photoinduced absorption and time-resolved photoluminescence, complementary techniques that allow studying charge photogeneration and recombination. We have estimated electron diffusion length in the considered configurations observing a decrease when the material is confined in the MS scaffold with respect to a planar architecture. However, the presence of perovskite overlayer allows an overall recovering of long diffusion lengths explaining the record PV performances obtained with a device configuration bearing both the mesostructure and a perovskite overlayer.

The samples were prepared by additional chromatographic purification of commercially available products. The mucin molecule was found to have a z-average hydrodynamic diameter of ca. 35 nm in phosphate buffered solution, without any particular secondary or tertiary structure. The contour length of the mucin is larger than, yet of the same order of magnitude as the diameter, indicating that the molecule can be modeled as a relatively rigid polymeric chain due to the large persistence length of the central glycosylated domain. Mucin molecules adsorbed abundantly onto mica from saline buffer, generating polymer-like, long-ranged, repulsive, and nonhysteretic forces upon compression of the adsorbed layers. Detailed analysis of such forces suggests that adsorbed mucins had an elongated conformation favored by the stiffness of the central domain. Acidification of aqueous media was chosen as means to reduce mucin-mucin and mucin-substrate electrostatic interactions. The hydrodynamic diameter in solution did not significantly change when the pH was lowered, showing that the large persistence length of the mucin molecule is due to steric hindrance between sugar chains, rather than electrostatic interactions. Remarkably, the force generated by an adsorbed layer with a fixed surface coverage also remained unaltered upon acidification. This observation can be linked to the surface-protective, pH-resistant role of bovine submaxillary mucin in the variable environmental conditions of the oral cavity. © 2015 American Chemical Society.},\npublisher={American Chemical Society},\nissn={07437463},\ncoden={LANGD},\npubmed_id={25806669},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Electromagnetic modes are represented by classical degrees of freedom of a Hamiltonian model at equilibrium in an effective ensemble corresponding to the stationary laser regime. By means of optimized Monte Carlo numerical simulations, the system properties are analyzed while varying mode interaction dilution, gain profile, and number of modes. Properties of the resulting mode-locking laser phase are presented that were not observed in previous approaches based on mean-field approximations. For strong dilution of the nonlinear interaction network, power condensation occurs as the total optical intensity is taken by a few electromagnetic modes, whose number does not depend on the size of the system.

The magnetic-field increments have been computed from single- and two-spacecraft measurements. The two-satellite technique allows us to study the increments as a function of an actual space lag. Both single- and two-point analyses show that the magnetic field is anisotropic even at small time/spatial scales. The single-spacecraft data also shows that the degree of anisotropy does not change with the scale at proton and subproton scales. It is also pointed out that the degree of magnetic-field anisotropy tends to be overestimated in the single-spacecraft data analysis. This is particularly evident at small scales and it depends on the angle between the spacecraft separation and the flow direction. From the fourth-order moment of the probability density function of the magnetic-field increments we have also investigated the presence of intermittency in the fluctuations. Even though to a different degree, intermittency was present over the entire range of scales, with an indication of scale invariance at subproton scales. © Copyright EPLA, 2015.},\npublisher={Institute of Physics Publishing},\nissn={02955075},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Structural and compositional analyses demonstrate that: (i) the conventional MAPLE process can induce self-reduction of the metal salt precursor, thereby leading to the formation of metallic Pd(0) NPs; (ii) the solvent critically determines the size, morphology, and size distribution of the resulting NPs; and (iii) the cumulative effects of laser-pulse number and solute concentration are less influential than the type of solvent used. For diethyl ether-derived samples, a bimodal distribution of NP sizes spanning from ~1 nm up to 20 nm was obtained. Conversely, by using acetone, a mono-modal distribution of sizes in the ~1 nm-6 nm range (mean diameter of 1.5±0.7 nm) and a more uniform and densepacked surface coverage (NP coverage was twice as dense as the one obtained with diethyl ether) resulted in. These observations point out that solvents with low dynamical viscosity coefficients and high volatility favor the formation of larger and more broadly dispersed NPs. A general theoretical picture has been proposed to describe the NP formation pathways on account of the solvent properties and the mechanisms underlying the MAPLE process enabled by the technique. © 2015 by American Scientific Publishers.},\npublisher={American Scientific Publishers},\nissn={19472935},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Both single and triple-nanowire geometries have been studied. In particular, we found that in single-helical nanostructures, the enhancement of chiro-optical effects achievable by geometrical design is limited, especially with respect to the operation wavelength and the circular polarization conversion purity. Conversely, in the triple-helical nanowire configuration, the dominant interaction is the coupling among the intertwined coaxial helices which is driven by a symmetric spatial arrangement. Consequently, a general improvement in the g-factor, extinction ratio and signal-to-noise-ratio is achieved in a broad spectral range. Moreover, while in single-helical nanowires a mixed linear and circular birefringence results in an optical activity strongly dependent on the sample orientation and wavelength, in the triple-helical nanowire configuration, the obtained purely circular birefringence leads to a large optical activity up to 8°, independent of the sample angle, and extending in a broad band of 500 nm in the visible range. These results demonstrate a strong correlation between the configurational internal interactions and the chiral feature designation, which can be effectively exploited for nanoscale chiral device engineering. © 2015 The Royal Society of Chemistry.},\npublisher={Royal Society of Chemistry},\nissn={20403364},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Indeed, the literature on the field reports apparently contradictory results about the effect of a metal on graphene doping. Here, we elucidate the effect of metal nanostructuring and oxidation on the metal work function (WF) and, consequently, on the charge transfer and doping of graphene/metal hybrids. We show that nanostructuring and oxidation of metals provide a valid support to frame WF and doping variation in metal/graphene hybrids. Chemical vapour-deposited monolayer graphene has been transferred onto a variety of metal surfaces, including d-metals, such as Ag, Au, and Cu, and sp-metals, such as Al and Ga, configured as thin films or nanoparticle (NP) ensembles of various average sizes. The metal-induced charge transfer and the doping of graphene have been investigated using Kelvin probe force microscopy (KPFM), and corroborated by Raman spectroscopy and plasmonic ellipsometric spectroscopy. We show that when the appropriate WF of the metal is considered, without any assumption, taking into account WF variations by nanostructure and/or oxidation, a linear relationship between the metal WF and the doping of graphene is found. Specifically, for all metals, nanostructuring lowers the metal WF. In addition, using gold as an example, a critical metal nanoparticle size is found at which the direction of charge transfer, and consequently graphene doping, is inverted. © The Royal Society of Chemistry.},\npublisher={Royal Society of Chemistry},\nissn={20403364},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

During their assembling process, perovskite components undergo very complex dynamic equilibria starting in solution and progressing throughout film formation. Finding a methodology to control and affect these equilibria, responsible for the unique morphological diversity observed in perovskite films, constitutes a fundamental step towards a reproducible material processability. Here we propose the exploitation of polymer matrices as cooperative assembling components of novel perovskite CH3NH3PbI3 : polymer composites, in which the control of the chemical interactions in solution allows a predictable tuning of the final film morphology. We reveal that the nature of the interactions between perovskite precursors and polymer functional groups, probed by Nuclear Magnetic Resonance (NMR) spectroscopy and Dynamic Light Scattering (DLS) techniques, allows the control of aggregates in solution whose characteristics are strictly maintained in the solid film, and permits the formation of nanostructures that are inaccessible to conventional perovskite depositions. These results demonstrate how the fundamental chemistry of perovskite precursors in solution has a paramount influence on controlling and monitoring the final morphology of CH3NH3PbI3 (MAPbI3) thin films, foreseeing the possibility of designing perovskite : polymer composites targeting diverse optoelectronic applications. © 2015 The Royal Society of Chemistry.},\npublisher={Royal Society of Chemistry},\nissn={20403364},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

First, graphite oxide (GO) was prepared by the Hummers' oxidation method, starting from high-surfacearea graphite. Then, rGO was generated from GO in aqueous suspension through a UV-irradiation treatment. The influence of different process parameters (including type of UV source, irradiation time and atmosphere) on the GO reduction efficiency was explored and evaluated on the basis of the data acquired by several experimental techniques, such as infrared spectroscopy in attenuated total reflectance mode, X-ray diffraction, UV-vis absorption spectrophotometry, X-ray photoelectron spectroscopy and thermogravimetry. The acquired results allowed identifying appropriate sets of reaction conditions under which GO reduction yield could be maximized. In particular, the highest reduction degree was obtained by exposing GO to UV light in a UV oven for 48 h under inert atmosphere. The reduction strategy developed by us represents an innovative low-cost and easy route to graphene-based nanomaterials, which does not require any stabilizer, photocatalyst or reducing agent. For this reason, our method represents an attractive environmentally friendly alternative approach for the preparation of stable rGO dispersions in large-scale amounts, to be utilizable in disparate engineering applications. © 2015 by American Scientific Publishers.},\npublisher={American Scientific Publishers},\nissn={19472935},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

It has been demonstrated that the obtainment of a complex target sensitizer can be exclusively pursued via direct arylation reactions. Green metrics comparison with those of a traditional synthetic pathway clearly indicates that the new approach has a lower environmental impact in terms of chemical procedures and generated wastes, stressing the importance of the synergy between the molecular design and the synthetic plan in the framework of environmentally friendly routes to back up sustainable development of third-generation photovoltaics. Additionally, the stability of the G3-based photovoltaic devices was also investigated in aging tests on large area devices, evidencing the excellent potentialities of the proposed structure for all practical applications involving inorganic semiconductor/organic dye interfaces. © 2015 American Chemical Society.},\npublisher={American Chemical Society},\nissn={21680485},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

All binding events ended with a rapid (&lt;10 ps) lock-in of the fatty acid due to formation of a hydrogen bond with Tyr401. The kinetics and energetics of the penetration process both depended linearly on the positional shift of the fatty acid, with an average insertion time and free energy reduction of, respectively, 32 ± 20 ps and 0.70 ± 0.15 kcal/mol per methylene group absorbed. Binding events of longer duration (tbind &gt; 1 ns) were characterized by a slow exploration of the pocket entry and, frequently, of a nearby protein crevice corresponding to a metastable state along the route to the binding site. Taken all together, these findings reconstruct the following pathway for the binding process of stearic acid: (i) contact with the protein surface, possibly facilitated by the presence of an intermediate location, (ii) probing of the site entry, (iii) insertion into the protein, and (iv) lock-in at the final position. This general description may also apply to other long-chain fatty acids binding into any of the high-affinity sites of albumin, or to specific sites of other lipid-binding proteins. © 2015 Elsevier Inc.

Remarkable advantages of using synthetic carriers include control over the lipid composition, structure and size, together with the possibility to add tracer molecules to monitor their in situ distribution via fluorescence microscopy. Over the past few years, new methods of vesicles production have been developed and optimized, such as those based on microfluidic techniques. These innovative approaches allow us to overcome the limitations faced in conventional methods of liposome preparation, such as size distribution and polydispersity. Herein, a Microfluidic Hydrodynamic Focusing (MHF) device has been used for the production of lipid-based vesicles with different lipid combinations that resemble natural exosomes, such as phosphatidylcholines (PC), cholesterol (Chol), dicetyl phosphate (DCP) and ceramide (Cer). Thanks to a fine control on fluid manipulation, the MHF device allows preparation of vesicles with controlled size, a relevant feature in the emerging field of carrier-assisted cell-delivery. Interestingly, PC/Chol/Cer vesicles exhibit low polydispersity and high stability up to 45 days. Later, quantum dots (QDs) were successfully embedded in these vesicles through the same preparation process. The development of QD-embedded lipid nanovesicles by MHF devices has never been described previously.},\npublisher={Royal Society of Chemistry},\nissn={20462069},\ncoden={RSCAC},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Interestingly, these anisotropic media support highly confined wavevector modes (high-k modes) in addition to surface plasmon modes within the structure due to hyperbolic dispersion. The high-k modes in an anisotropic hyperbolic metamaterials are conventionally refereed to as volume plasmon polaritons (VPPs) or bulk Bloch plasmon polaritons (BPPs). Since BPPs are highly confined within the entire structure, the excitation, collection and control those modes at optical frequencies are very challenging. Here, the focus will be on the excitation and collection of bulk plasmon polaritons from anisotropic hyperbolic metamaterials at optical frequencies using the grating coupling principle. In this chapter, the basic properties of hyperbolic metamaterials are first introduced. Then we give a comprehensive overview, describing on design, fabrication and characterization of grating coupled anisotropic hyperbolic metamaterials (GCAHMs) in a wide wavelength range, from visible to near infrared. Numerical simulation results supporting the obtained experimental data are also presented. Finally, we describe potential applications of GCAHMs in photonics and biomedical research with concluding remarks. © Springer International Publishing Switzerland 2015.},\npublisher={Springer Verlag},\nissn={14344904},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

In particular, graphene, a 2D version of graphite, exhibits a remarkably high absorption value (∼2.3%) in the visible range [1] when compared to metals or dielectric materials. In this paper, we will review and illustrate the quest for the enhanced absorption in photonic nanostructures that incorporate monolayer and multilayer graphene sheets emphasizing the difference in terms of configurations and strategies proposed in literature. Then, we will detail the optical performance of graphene-based one-dimensional (1D) gratings that support guided mode resonances showing how it is possible to tune theoretically and experimentally their total absorption ranging from 2.3% to perfect absorption by means of metallic and dielectric reflectors or engineered super cells. © 2015 IEEE.},\neditor={Jaworski M., Marciniak M.},\npublisher={IEEE Computer Society},\nissn={21627339},\nisbn={9781467378802},\ndocument_type={Conference Paper},\nsource={Scopus},\n}\n\n

The residual organics on nanoparticles surfaces were completely removed under ozone flow at room temperature in air. The TiO2 nanorods, with average lengths of 27.6 ± 5.8 nm and average diameters of 3.2 ± 0.4 nm, were characterized by powder X-Ray diffraction, transmission electron microscopy, selected area diffraction, BET surface area analysis and FT-IR spectroscopy. The photocatalytic performances of the as-synthesized TiO2 nanorods and platinum loaded TiO2 nanorods were implemented with respect to both commercial P25 and platinum loaded P25. Performance enhancements should be attributed to effects like differences in the adsorption capacity and in the separation efficiency of the photogenerated electrons-holes. © 2015 Author(s).},\npublisher={SAGE Publications Inc.},\nissn={18479804},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Anatase nanocrystals were characterized by transmission electron microscopy (TEM), Brunauer-Emmett-Teller (BET) surface analysis and dynamic light scattering (DLS). The proteinnanoparticles' interactions and their eventual reversibility were studied by pH dependent ζ- potential measurements in different media: ultra-pure water, a phosphate buffer simulating physiological conditions and in a culture medium supplemented with foetal bovine serum. The protein corona masking effect was evidenced and the interaction HSA-nanocrystals resulted irreversible. The interaction HSA-silicon supported TiO2 nanocrystals films was studied by atomic force microscopy (AFM), and resulted driven by the substrate hydrophilicity degree plus was different for the diverse range of nanocrystals tested. Surface roughness measurements showed that on some of the nanocrystals, HSA were arranged in a more globular manner. A lower protein affinity was found for nanocrystals that had a smaller primary particle size, which may correspond to their higher biocompatibility. This nano-bio interface research aimed to study the HSA protein-TiO2 anatase nanocrystals under conditions similar to those for in vitro and in vivo toxicity analyses. © 2015 Author(s).

Here, we report on the interplay between plasmons and excitons as a potential approach to selectively reduce ohmic losses. Samples were prepared by functionalizing plasmonic core-shell nanostructures with excitonic molecules embedded in silica shells and interlocked by silica spacers to investigate the role played by the plasmon-exciton elements separation. Results obtained for different silica spacer thicknesses are evaluated by comparing dispersions of plasmonic multimers with respect to the corresponding monomers. We have observed fluorophore emission quenching by means of steady-state fluorescence spectroscopy, as well as a significant shortening of the corresponding fluorescence lifetime using TCSPC data. These results are accompanied by the simultaneous enhancement of Rayleigh scattering and transmittance, revealing more effective absorptive loss mitigation for multimeric systems. Moreover, upon decreasing the thickness of the intermediate silica layer between gold cores and the external gain functionalized silica shell, the efficiency of exciton-plasmon resonant energy transfer (EPRET) was significantly enhanced in both multimeric and monomeric samples. Simulation data along with experimental results confirm that the hybridized plasmon fields of multimers lead to more efficient optical loss compensation with respect to the corresponding monomers. © The Royal Society of Chemistry 2015.},\npublisher={Royal Society of Chemistry},\nissn={20462069},\ncoden={RSCAC},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

A model for passive mode locking lasers is analyzed beyond the mean-field approximation, accounting for the presence of many well-resolved frequencies of the lasing modes. The inhomogeneous structure in the nonlinear "mode locked" interaction network is shown to yield short pulses and phase waves with nontrivial slopes, corresponding to a phase delay of the pulsed laser signal. The analytic solution of a mean field-model for multimode laser in open and irregular cavities will be, afterwards, addressed. The complete phase diagram, in terms of degree of disorder, pumping rate of the source and strength of nonlinearity, consists of four different photonic regimes: incoherent fluorescence, mode locking, random lasing and the novel "phase locking wave". A replica symmetry breaking transition occurs at the random lasing threshold. For a high enough strength of nonlinearity, a whole region with nonvanishing complexity anticipates the transition and the light in the disordered medium displays typical glassy behavior.},\npublisher={Electromagnetics Academy},\nissn={15599450},\nisbn={9781934142301},\ndocument_type={Conference Paper},\nsource={Scopus},\n}\n\n

It was successfully applied for the cold flow control in aero engines and turbo-devices. One important application concerns the use of non-equilibrium plasma for plasma-assisted ignition and combustion control. The reduction of nitric oxides (NOx) in aircraft engines, gas turbines, or internal combustion engines has become a major issue in the development of combustion systems. A way to reduce the NOx emissions is to burn under homogenous lean conditions. However, in these regimes the flame becomes unstable and it leads to incomplete combustion or even extinction. Thus, the major issue becomes to stabilize the flame under lean conditions. In this context the present work aims to demonstrate the possibility to increase the combustion efficiency of a lean flame through the use of nanosecond repetitively pulsed plasma (NRPP). A NRPP produced by electric pulses with amplitude up to 40 kV, pulse rise time lower than 4 ns and repetition rate up to 3.5 kHz has been used to stabilize and improve the efficiency of a lean non premixed methane/air flame in a non-premixed Bunsen-type burner. The burner is optically accessible permitting the imaging acquisitions of the flame region. The flame behavior was acquired using a high rate CCD camera in order to capture the differences between the baseline conditions and the actuated cases. Moreover a post-processing technique showing the jagging of the flame in different conditions was applied to evaluate the changes occurring in presence of plasma actuation in term of flame area weighted respect to the luminosity intensity. It was shown that the plasma significantly allows stabilizing the flame under lean conditions where it would not exist without plasma. © 2015 The Authors.
