Аннотация: The effect of restricted geometry on specific heat capacity and thermal expansion of the triglycine sulfate (TGS)–borosilicate glass composites have been studied first. A decrease in the entropy and temperature of the P21 ↔ P21/m phase transition in the TGS component with decreasing the glass matrix pore diameter at the invariable specific heat and thermal expansion coefficient has been observed. The estimates are indicative of the minor effect of internal pressure on the TGS pressure coefficient dTC/dp in the composites.

Аннотация: The aim of this paper was to study the effect of nanoscale inclusions of CuO as the second ingredient of composites on transport properties of superconducting YBa2Cu3O7 polycrystals. The samples of YBa2Cu3O7−δ with different content of CuO nanoparticles were synthesized. The analysis of the magnetic properties was carried out within the extended critical state model. It was found that the addition of 0.5 and 1% of CuO nanoparticles leads to an increase in the intragranular density of the critical current at T= 4.2 K. A further increase of x from 2 to 15% and more than 40% decreases the critical current density. The critical current density higher than in the reference sample was also found in the samples with x= 20% and x= 24%.

Bacterial cellulose -- Composites -- Silver nanoparticles -- Antibiotics -- Properties -- Antibacterial activity
Аннотация: The present study describes production of bacterial cellulose composites with silver nanoparticles and antibiotics and compares their properties. Bacterial cellulose (BC) composites synthesized in the culture of the strain of acetic acid bacterium Komagataeibacter xylinus VKPM B-12068 with silver nanoparticles, BC/AgNps, were produced hydrothermally, under different AgNO3 concentrations (0.0001, 0.001, and 0.01 M) in the reaction medium. The presence of silver in the BC/AgNp composites was confirmed by elemental analysis conducted using scanning electron microscopy with a system of X-ray spectral analysis. Analysis showed that the average atomic number of silver particles in composite samples depended on the concentration of AgNO3: as AgNO3 concentration in the reaction solution was increased, silver content in the composites increased from 0.044 to 0.37 mg/cm2. BC composites with amikacin and ceftriaxone were prepared by immersing dry BC films in solutions containing different concentrations of the antibiotics. The surface structure and properties and physicochemical and mechanical characteristics of composites were investigated using SEM, DSC, X-ray analysis, the system for measuring water contact angles, and electromechanical tensile testing machine. The disk-diffusion method and the shake-flask culture method used in this study showed that all experimental composites had pronounced antibacterial activity against E. coli, Ps. eruginosa, K. pneumoniae, and St. aureus, and the BC/antibiotic composites were more active than BC/AgNp ones; S. aureus was the most susceptible to the effect of BC composites. No potential cytotoxicity was detected in any of the BC/AgNp composites in the NIH 3T3 mouse fibroblast cell culture, in contrast to the BC/antibiotic composites. These results suggest that BC composites constructed in the present study hold promise as dressings for managing wounds, including contaminated ones.

Аннотация: The model of a polarization-preserving anisotropic mirror is proposed. The mirror is a plane boundary of a metal–dielectric nanocomposite that consists of silver spheroidal nanoparticles dispersed in a transparent matrix. The dependence of reflection spectra on the shape of the nanoparticles is studied. It is shown that in one region of the spectrum, the mirror preserves the sign of polarization in the reflected light. © 2017, Allerton Press, Inc.

Carbon nanotubes -- LSMO -- Interface -- Spin polarization
Аннотация: Atomic and electronic structure of LSMO-based composites with carbon nanotubes were studied by means of density functional theory with respect to the termination of LSMO surface. The deformation of the tubes caused by the lattice mismatch with the substrate leads to a major change in their electronic structure. The surface terminated with Mn-O layer provides much stronger interaction with carbon nanotubes than Sr-O terminated one does. The interaction with transition metal atoms is essential for spin polarization of the nanotube while no spin injection was observed for Sr-O-supported tubes. © 2017 Elsevier B.V.

Аннотация: Получены композиты на основе сверхвысокомолекулярного полиэтилена и углеродных нанотрубок методом смешивания компонентов в ксилоле при определенных температурах. Комплексные проводимости и диэлектрические проницаемости образцов материалов измерены в диапазоне частот от 100 Гц до 1 ГГц. Установлены условия синтеза как электропроводящих, так и диэлектрических композитов. При этом величина проводимости зависит не только от концентрации углеродных нанотрубок, но и от структуры их распределения в полимерной матрице, которая, в свою очередь, зависит от температурных условий получения композита.
Composites based on ultrahigh-molecular-weight polyethylene and carbon nanotubes were obtained by mixing the components in xylene at certain temperatures. The complex conductivities and permittivities of the material samples were measured in the frequency range from 100 Hz to 1 GHz. The conditions for the synthesis of both electrically conducting and dielectric composites were established. The conductivity depends not only on the concentration of carbon nanotubes, but also on the structure of their distribution in the polymer matrix, which in turn depends on the temperature conditions for obtaining the composite.

Zinc oxide -- Amorphous carbon -- Multi-layered structures -- Composites -- Hopping conductivity -- Weak localization -- Magnetoresistance
Аннотация: ZnO- and C-based heterostructures were fabricated by the layer-by-layer deposition technique using the ion-beam sputtering process. Structure, electrical and magnetic properties of fabricated heterostructures are discussed. The two-phase (ZnO and C) films are evolved into a multilayer structure, consisting of amorphous carbon and crystalline ZnO layers when the bilayer thickness increases. When carbon is added to ZnO, its electrical resistivity reduces. The conduction mechanism changes from the variable-range hopping in a narrow energy band to the nearest neighbors hopping in ZnO–C films with a thickness of h ˂ 150 nm. The temperature dependence of conductivity changes from the Arrhenius-like to logarithmic law, indicating that the strong charge localization turns into a weak one when the film thickness is about 150 nm. The negative magnetoresistance of up to 1% was detected at 77 K. The film ferromagnetism at the temperature of 10 K was not found.
