The dependence of the magnetic correlation radius and the average magnetic anisotropy constant on the intrinsic size of the phase inhomogeneity was founded. The data allows estimating the applicability limits of the analytical equations for the magnetization curves approaching saturation of two-phase ferromagnetic nanomaterials.

Аннотация: Polymer-based dielectric capacitors play a notable part in the practical application of energy storage devices. Graphene oxide (GO) nanosheets can improve the dielectric properties of polymer-based composites. However, the breakdown strength will greatly reduce with the increase of GO content. Hence, the construction of sandwich structure can enhance the breakdown strength without reducing the dielectric constant. Herein, single-layered and sandwich-structured poly(vinylidene fluoride-co-chlorotrifluoroethylene) (P(VDF-CTFE)) nanocomposites with low content of GO nanosheets (1.0 wt%) are prepared via employing a straightforward casting method. Compared with the single-layered composites and pure P(VDF-CTFE), the sandwich-structured composites exhibit comprehensively better performance compared. The sandwich-structured composite with 0.4 wt% GO nanosheets show an excellent dielectric constant of 13.6 (at 1 kHz) and an outstanding discharged energy density of 8.25 J cm−3 at 3400 kV cm−1. These results demonstrate that the growth of the dielectric properties is owing to 2D GO nanosheets and the enhancement of breakdown strength due to the sandwich structure. The results from finite element simulation provide theoretical support for the design of high energy density composites.

Аннотация: The properties of Co-SiO2 nanogranular composite films, containing a Co volume fraction ranging from 0.3 to 0.8, have been characterized by means of magnetic measurements, NMR study, and ferromagnetic resonance. Thermal decrease of CoX(SiO2)100-X magnetization follows the T3/2 law and allows to estimate the exchange interaction constant A. With growing nominal Co content the transitions from granular to continuous structural state at 36% Co are registered by FMR measurements. The spectrum of standing spin-wave has been detected in the perpendicular experiment configuration for films with the Co content above 52 vol. %. It is found that the type of the dispersion relation of spin waves in Co-SiO2 composite films is affected by the exchange coupling fluctuations.

Аннотация: Light scattering and transmission by a monolayer polymer dispersed liquid crystal film containing liquid crystal droplets with inhomogeneous anchoring of liquid crystal molecules at the polymer-droplet interface is considered theoretically and experimentally. The developed optical model is based on the anomalous diffraction and interference approximations of the theory of scattering of waves. It is applied to describe the interference quenching effect for the coherently transmitted light and electrically controllable symmetry breaking effect in small-angle structure of light scattered by film containing droplets with inhomogeneous anchoring. The analysis of transmittance and reflectance of the one-dimensional photonic crystals composed of monolayers is carried out. The formation of the photonic band gaps is analyzed.

Аннотация: Magnetic nanocomposites containing iron oxide and gold components take great attention last years because of their relative biocompatibility and the ability to combine the magnetic properties of iron and the chemical bonding properties of gold for the possible drug delivery or diagnostics for various diseases. However, such particles have some toxicity to living cells, and the effect depends on many factors, including size, shape, the ratio of components in the composites, and the type of cells affected. And thus, the search for compositions and technologies for producing iron-gold particles with improved properties and reduced cytotoxicity remains relevant. The aim of the study was to synthesize and characterize Fe3O4/Au nanocomposites and evaluate their influence on living cells using the example of cell line HEK293. Fe3O4 nanoparticles (NPs) were synthesized by co-precipitation of Fe2+/Fe3+ water solution in alkaline conditions and then boiled with HAuCl4 in 0.1 M sodium citrate. The NPs properties were estimated by transmission electron microscopy (TEM), vibration magnetometry and ferromagnetic resonance (FMR). According to magnetometric measurements, nanoparticles are mainly in a superparamagnetic state. By fitting magnetization curves, the magnetic characteristics of nanoparticles were determined: saturation magnetization (59.3 emu/g) and magnetic anisotropy constant (K = 0.86·105 erg/cm3). The average particle size estimated from magnetic measurements was 8.7 nm. Considering the presence of a magnetically dead layer, this is in good agreement with the TEM results. The temperature dependence of the FMR linewidth was analyzed using two models. As a result, the parameters MSV and K/MS were determined. The models used showed good agreement. The values of the anisotropy constant (K = 1.06·105 erg/cm3) and the average particle size (6.8 nm) are estimated. The effect of the NPs on the HEK293 cells was studied by MTT-assay, flow cytometry and RT-PCR. The exposure with the NPs lead to a significant decrease of cell metabolic activity in HEK293 cell culture, but this effect was not accompanied by cell death. It was shown that the expression of antioxidant enzymes SOD1 and GPX1 was reduced at the mRNA stage. So the NPs synthesized may affect gene expression and metabolism of HEK293 cells, but this does not have fatal consequences for cell viability.

Аннотация: Perovskite-based nanocomposites have garnered significant interests due to their potential in interfacial engineering, optical modification, and stability enhancement. However, current understanding of the construction models between perovskites and guest materials is limited, and the design concept of perovskite-based nanocomposites remains unclear. Herein, we thoroughly investigate the effects of amino bridge linkage in attapulgite@perovskite nanocomposites on the crystallization kinetics, optical properties, and stabilities of perovskites by monitoring the difference in structural, compositional, and morphological characteristics. The attapulgite@perovskite nanocomposite with amino bridge linkage exhibited a smaller average size distribution of 23.8 ± 5.8 nm, along with enhanced thermal stability (81% relative PL intensity after a heating-cooling cycle) and photo-stability (84% relative PL intensity after 30 h ultraviolet light irradiation). These improvements can be attributed to the adequate passivation of amino bridge linkages. Our work aims to provide a deeper understanding of perovskite-based nanocomposite construction and inspire new approaches for modifying their optical properties and enhancing their stability.

Место публикации : Журн. СФУ. Техн. и технол. - 2022. - Т. 15, № 7. - С. 802-811. - ISSN 1999494X (ISSN), DOI 10.17516/1999-494X-0437; J. Sib. Fed. Univ. Eng. Technol. - ISSN 23136057 (eISSN)

Аннотация: Методом импедансной спектроскопии исследованы электрофизические свойства композитного материала на основе сверхвысокомолекулярного полиэтилена с ограниченной массовой концентрацией 0,5 мас.% оксида меди CuO в диапазоне частот от 102 до 108 Гц. Предполагается, что введение в состав полимера малых концентраций наночастиц способствует более равномерному их осаждению на поверхностях полимерных гранул. Это позволяет в процессе тестирования таких образцов выявить наиболее вероятные механизмы их поляризации и протекания электрического тока в относительно однородном ансамбле наночастиц в полимерной матрице. Установлено, что внедряемые в полимерную матрицу наночастицы незначительно влияют на процессы электрической поляризации, но приводят к появлению частотно-зависимой проводимости в широком диапазоне частот. Этот процесс сопровождается существенным возрастанием диэлектрических потерь. Электрофизические характеристики полученных композитов обсуждаются с учётом переноса электрических зарядов (ионов или электронов) как по внутренней, так и по поверхностной структуре наночастиц CuO.The electrophysical properties of a composite material based on ultrahigh molecular weight polyethylene with a limited mass concentration of 0.5 wt% copper oxide CuO in the frequency range from 102 to 108 Hz were studied by impedance spectroscopy. It is assumed that the introduction of low concentrations of nanoparticles into the polymer composition contributes to their more uniform deposition on the surfaces of polymer granules. This makes it possible to reveal the most probable mechanisms of their polarization and the flow of electric current in a relatively homogeneous ensemble of nanoparticles in a polymer matrix during testing of such samples. It has been established that nanoparticles introduced into the polymer matrix have little effect on the processes of electric polarization, but lead to the appearance of frequency-dependent conductivity in a wide frequency range. This process is accompanied by a significant increase in dielectric losses. The electrophysical characteristics of the resulting composites are discussed taking into account the transfer of electric charges (ions or electrons) both along the internal and surface structures of CuO nanoparticles.

Аннотация: We present results of magneto-optical investigations of (CoFeZr)x(Al2O3)100-x film nanocomposites in transverse Kerr effect (TKE) geometry in the spectral range 0.5-4.0eV and magnetic field up to 3.0kOe. Nanocomposites were deposited onto a glass-ceramic substrate by ion-beam sputtering. The TKE response at room temperature strongly depends on the wavelength of light, applied magnetic field H and the volume metallic fraction. From the analysis of the field dependences of TKE at different wavelengths, it follows that in the as-deposited samples, the interaction between nanoparticles at x30at.% is small and the nanocomposite is an ensemble of superparamagnetic particles; as x increases to 32at.%, a superspinglass-type state arises, then, in the vicinity of 34at.%, along with individual superparamagnetic particles, superferromagnetic regions appear. Long-range ferromagnetic order arises at concentrations x less than the percolation threshold for conductivity xper

Аннотация: Morphology, structure, magnetic properties and magnetic circular dichroism (MCD) were studied for the FexSy and FexSey nanoparticles (NPs) synthesized with the polyol mediated and the thermal decomposition processes, correspondingly, at different regimes. For all NPs samples, but Fe3S4, MCD was measured for the first time. It has been shown that in the case of sulfides, the character of the MCD spectrum changes as the NPs phase composition transforms from Fe3S4 to FeS with the synthesis temperature increase. At the same time, the shape of the MCD spectrum is almost independent of the NPs phase in the case of iron selenides.
