We propose a label-free procedure applied on a device structure where the electrical signal transduction is evaluated via impedance spectroscopy techniques.

\n Early diagnosis of plant virus infections before the disease symptoms appearance may represent a significant benefit in limiting disease spread by a prompt application of appropriate containment steps. We propose a label-free procedure applied on a device structure where the electrical signal transduction is evaluated via impedance spectroscopy techniques.

This study provides useful insights into the complex interaction of anisotropic nanoparticles and anisotropic soft materials such as LCs in the presence of external fields, which may help the development of field-responsive nanoparticle-based functional materials. © 2016 WILEY-VCH Verlag GmbH & Co.

These findings are fully supported by an analytical approach based on an equivalent circuital model. Engineering and integration of graphene sheets could facilitate the realization of innovative microwave absorbers with additional electromagnetic and optical functionalities that could circumvent some of the major limitations of opaque microwave absorbers. © 2016 Optical Society of America.\n

Therefore, biocompatibility of halloysite represents one the main requisites for the employment of HNTs for clinical purposes. Here we present a study aimed at assessing HNTs biocompatibility before and after their surface coating with poly(ethylene glycol) (PEG), a polymer which has been reported to increase biocompatibility, to prolong circulation time, and to prevent protein adsorption and aggregation in biological environments. The dose- and time-dependent cytotoxicity of noncoated and PEG-coated HNTs obtained was evaluated in vitro by MTT cell viability assay carried out on both HeLa and HepG2 cells, two different human cancer cell lines. Binding and uptake of nanotubes were also analyzed at ultrastructural level by transmission electron microscopy. Interestingly, the results obtained showed that both the HNTs tested were actively taken up by the cells but, while noncoated nanotubes exhibited significant concentration- and time-dependent toxicity, PEG-coated HNTs were found to be highly biocompatible, being then suitable candidates for biomedical applications. © 2002-2012 IEEE.},\npublisher={Institute of Electrical and Electronics Engineers Inc.},\nissn={1536125X},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Owing to this feature, they were found to be a suitable nanosized container for the loading of biologically active molecules like biocides and drugs. Also, HNTs have been reported to be of potential interest for other biological applications, such as gene delivery carriers, ultrasound contrast agents, cancer therapy, and stem cells isolation. Therefore, biocompatibility of halloysite represents one the main requisites for the employment of HNTs for clinical purposes. Here we present a study aimed at assessing HNTs biocompatibility before and after their surface coating with poly(ethylene glycol) (PEG), a polymer which has been reported to increase biocompatibility, to prolong circulation time, and to prevent protein adsorption and aggregation in biological environments. The dose- and time-dependent cytotoxicity of noncoated and PEG-coated HNTs obtained was evaluated in vitro by MTT cell viability assay carried out on both HeLa and HepG2 cells, two different human cancer cell lines. Binding and uptake of nanotubes were also analyzed at ultrastructural level by transmission electron microscopy. Interestingly, the results obtained showed that both the HNTs tested were actively taken up by the cells but, while noncoated nanotubes exhibited significant concentration- and time-dependent toxicity, PEG-coated HNTs were found to be highly biocompatible, being then suitable candidates for biomedical applications. © 2002-2012 IEEE.\n

New solid phases have been observed when Ga is confined at the nanoscale. Herein, we demonstrate the stable coexistence, from 180 K to 800 K, of the unexpected solid γ-phase core and a liquid shell in substrate-supported Ga nanoparticles. We show that the support plays a fundamental role in determining Ga nanoparticle phases, with the driving forces for the nucleation of the γ-phase being the Laplace pressure in the nanoparticles and the epitaxial relationship of this phase to the substrate. We exploit the change in the amplitude of the evolving surface plasmon resonance of Ga nanoparticle ensembles during synthesis to reveal in real time the solid core formation in the liquid Ga nanoparticle. Finally, we provide a general framework for understanding how nanoscale confinement, interfacial and surface energies, and crystalline relationships to the substrate enable and stabilize the coexistence of unexpected phases. © The Author(s) 2016.},\npublisher={Nature Publishing Group},\nissn={14761122},\ncoden={NMAAC},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

\n Gallium (Ga), a group III metal, is of fundamental interest due to its polymorphism and unusual phase transition behaviours. New solid phases have been observed when Ga is confined at the nanoscale. Herein, we demonstrate the stable coexistence, from 180 K to 800 K, of the unexpected solid γ-phase core and a liquid shell in substrate-supported Ga nanoparticles. We show that the support plays a fundamental role in determining Ga nanoparticle phases, with the driving forces for the nucleation of the γ-phase being the Laplace pressure in the nanoparticles and the epitaxial relationship of this phase to the substrate. We exploit the change in the amplitude of the evolving surface plasmon resonance of Ga nanoparticle ensembles during synthesis to reveal in real time the solid core formation in the liquid Ga nanoparticle. Finally, we provide a general framework for understanding how nanoscale confinement, interfacial and surface energies, and crystalline relationships to the substrate enable and stabilize the coexistence of unexpected phases. © The Author(s) 2016.\n

We addressed the role of both poly(3-hexylthiophene) and colloidal arenethiolate-capped PbS quantum dots, which constitute the hybrid composite nanomaterial, in the photoinduced processes most relevant to device operation by changing the compositional ratio and applying chemical and thermal postdeposition treatments. The carrier generation processes were found to be wavelength-dependent: excitons generated in the polymer domains led to long-lived weakly bound charge pairs upon electron transfer to PbS nanocrystals; whereas charge carrier generation in the nanocrystal domains is highly efficient, although effective separation required the application of external electric field. Overall, charge carrier generation was found efficient and almost independent of the strength of applied electric field; therefore, competition between separation of electron-hole pairs into free carriers and geminate recombination is the major factor limiting the fill factor of nanocomposite-based solar cells. Device efficiency improvements thus require faster interfacial charge transfer processes, which are deeply related to the refinement of nanocrystal surface chemistry. © 2016 American Chemical Society.},\npublisher={American Chemical Society},\nissn={19327447},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

\n Here we investigate charge carrier generation and extraction processes in hybrid polymer/nanocrystal solar cells by means of time-resolved optical and photoelectrical techniques. We addressed the role of both poly(3-hexylthiophene) and colloidal arenethiolate-capped PbS quantum dots, which constitute the hybrid composite nanomaterial, in the photoinduced processes most relevant to device operation by changing the compositional ratio and applying chemical and thermal postdeposition treatments. The carrier generation processes were found to be wavelength-dependent: excitons generated in the polymer domains led to long-lived weakly bound charge pairs upon electron transfer to PbS nanocrystals; whereas charge carrier generation in the nanocrystal domains is highly efficient, although effective separation required the application of external electric field. Overall, charge carrier generation was found efficient and almost independent of the strength of applied electric field; therefore, competition between separation of electron-hole pairs into free carriers and geminate recombination is the major factor limiting the fill factor of nanocomposite-based solar cells. Device efficiency improvements thus require faster interfacial charge transfer processes, which are deeply related to the refinement of nanocrystal surface chemistry. © 2016 American Chemical Society.\n

With a detection limit as low as 5.00 CFU ml-1 for L. monocytogenes and 1.26 CFU ml-1 for S. aureus, our platform may be a promising point-of-care device not only for clinical and food diagnostics but also for biosecurity purposes. © The Royal Society of Chemistry 2016.\n

Subtle stoichiometry deviations from the corresponding bulk standards are revealed. NCs exposed to air at room temperature are monitored by XPD measurements at scheduled time intervals. The static PDF analysis is complemented with an investigation into the evolution of the WO3-x NC structure, performed by applying the modulation enhanced diffraction technique to the whole time series of XPD profiles (dynamical analysis). Prolonged contact with ambient air is found to cause an appreciable increase in the static disorder of the O atoms in the WO3-x NC lattice, rather than a variation in stoichiometry. The time behavior of such structural change is identified on the basis of multivariate analysis. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.\n

\n We report a strategy to assemble and manipulate nanoparticles arrays. The approach is based on the use of topological defects, namely disclination lines, created in chiral liquid crystals. The control of nanoparticle-loaded topological defects by low power light is demonstrated. Large-scale rotation, translation and deformation of quantum dots light-emitting chains is achieved by homogeneous LED illumination. Full reconfigurability and time stability make this approach attractive for future developments and applications.\n

The obtained results from the 12 compounds highlight the difficult to correlate photophysical properties in solution to the stereochemistry, while excited states decay studies of the solid state samples indicate a correlation between photophysics and packing mode which is affected by the different stereochemistry. © 2015 Elsevier B.V.

BTDs, acting as AMPA positive allosteric modulators, potentiate the glutamatergic neurotransmission without the side effects typically associated with direct agonists.

\n Benzothiadiazine type compounds (BTDs) have gained great attention for their potential therapeutic activity as nootropic and neuroprotective agents. BTDs, acting as AMPA positive allosteric modulators, potentiate the glutamatergic neurotransmission without the side effects typically associated with direct agonists. Studies regarding the binding mode of racemic BTDs into the receptor binding pocket demonstrated that one enantiomer establishes a more favourable interaction and possesses a higher biological activity with respect to the other one. The S enantiomer was proved to be the eutomer for both IDRA21 and S18986, two of the most studied BTD AMPA positive allosteric modulators. However, recent data highlighted an opposite stereoselectivity for some substituted BTDs (7-chloro-9-(furan-3-yl)-2,3,3a,4-tetrahydro-1H-benzo[e]pyrrolo[2,1-c][1,2,4]thiadiazine 5,5-dioxide and 7-chloro-2,3,4-trimethyl-3,4-dihydro-2H-benzo[e][1,2,4]thiadiazine 1,1-dioxide) showing unexpected structure-activity relationships.

\n Three novel 2D-π-A metal-free organic dyes TK 7–9 containing a dibenzofulvene (DBF) linked to two thiophene units as the π-bridge, diarylamines with and without alkoxy chains as donor groups and the cyanoacrylic acid moiety as the acceptor and anchoring group were synthesized. The new dyes TK were characterized by optical and electrochemical measurements and density functional theory calculations and were used as sensitizers in liquid dye-sensitized solar cells. The effects of alkoxy-functionalization of donor moiety and of hexyl chain insertion onto one thienyl ring of π-linker on dye properties and performances were investigated. The results discover the dye TK7, bearing two simple diphenylamine groups without alkoxy chains, exhibits the best behavior in terms of light absorption and cell performance (PCE of 7.9% and photovoltaic parameters of Jscof 17.82 mA cm−2, Vocof 670 mV and FF of 0.66). Lower power conversion efficiencies of 6.3% and 6.1% were found for TK8 and TK9, respectively, as a consequence of the presence of the alkoxy chains. © 2016 Elsevier Ltd\n
