Аннотация:
The morphotypes of human macrophages (MPh) were studied in the culture on nano-structured substrates, made from polyhydroxyalcanoates (PHAs) of various monomer compositions, prepared by casting polymer solutions on a defatted glass and followed by the solvent evaporation. Its surface relief, being further in direct contact with human cells in vitro was analyzed by AFM and SEM scanning. It was shown, that the features of micro/nano relief depend on the monomeric composition of polymer substrates. Monocytes (MNs) of patients with atherosclerosis and cardiac ischemia undergoing stenting and conventional anti-atherosclerotic therapy were harvested prior to and after stenting. After isolation MNs were cultured and transformed into MPh in direct contact with biopolymer culture substrates with different monomer composition and Nano-reliefs in comparison with culture plastic. Sub-populations of cells with characteristic morphology in each phenotypic class were described and their ratios for five samples of polymers were counted as an intermediate result in the development of “smart” material for blood vessel recovery. The results obtained allow us to assume that the processes of MPh differentiation and
polarization
in vitro depend not only on the features of the micro/nano relief of biopolymer substrates but also on the initial state of MNs in vivo and the general response of patients.

Аннотация:
An optical-mechanical model has been developed to describe the transmittance,
polarization
and small-angle distribution of light scattered by an uniaxially-stretched polymer film containing the elongated ellipsoidal droplets of nematic liquid crystal. It is based on the approximations of Foldy-Twersky, anomalous diffraction, and single scattering. The spectral dependences of transmittances and polarizing abilities of the polymer dispersed liquid crystal films have been analyzed as well as the small-angle intensity distribution and the
polarization
degree of scattered light depending on the film thicknesses, refractive index of polymer matrix, sizes of droplets, their anisometry parameters, concentration, polydispersity, and optical axes orientation. The optical characteristics of films with homogeneous and inhomogeneous interfacial anchoring at the surface of liquid crystal droplets have been considered. The transmittance and polarizing ability of the films have been studied as functions of the angular aperture of the system recording scattered light. © 2019 Elsevier Ltd

Аннотация:
SmFe3(BO3)4 single crystals have been grown from the bismuth trimolybdate and lithium tungstate-based melt–solutions. Samarium ferroborate single crystals were grown first from the lithium–tungstate flux. The magnetic and magnetoelectric properties of the synthesized crystals have been compared. It is shown that the SmFe3(BO3)4 ferroborate grown from the bismuth trimolybdate-based melt–solution contains impurities of Bi3+ ions (∼5% at.), which replace Sm3+ ions, while the SmFe3(BO3)4, ferroborate grown from the lithium tungstate-based melt–solution contains minor or zero amounts of such impurities. The magnetoelectric and magnetodielectric effects with the Bi3+ admixture appeared 1.5× stronger than in SmFe3(BO3)4; this is probably due to twinning.

Аннотация:
The structure consisting of alternating uniaxial dielectric layers is known to produce reflection of the same
polarization
as the incident field; e.g., the right-hand elliptically polarized light preserves this right-handedness and ellipticity of
polarization
at reflection. The parameters permitting the properly-polarized reflectance to exceed 99% in a wide frequency range were considered both analytically and numerically. The mirror with tuned top-layer thickness is shown to have several times less
polarization
losses than the uniform mirror. The hybrid mirror with metallic bottom layer has a considerably reduced thickness.

Аннотация:
To establish the existence of dipole glass in the chromium-substituted bismuth pyrostannate solid solutions, the frequency and temperature dependences of the permittivity have been measured in the temperature range of 300–750 K. The field and dynamic dependences of
polarization
in the temperature range of 80–550 K have been determined. Using the Raman scattering spectra, the absence of inversion center has been established. The maximum of electrical resistance has been found in the vicinity of the dipole moment freezing point. The carrier type has been determined from the thermopower data. The
polarization
relaxation is shown to be nonexponential. The experimental data are explained within the model of dipole glass in the α- phase and the model of charged crystalline domain walls with the electron-
polarization
relaxation mechanism above the α–β structural transition.

Аннотация:
The article presents, for the first time, the results of the research on composite film obtained from hydroxylated endohedral metallofullerenes (EMF) Y@C82, Y2@C82, with Y2C2@C82 and highest fullerenes as dopant. The composite film has been established to have electric conductivity and to be a ferroelectric with the value of residual
polarization
of ∼0.75 μC/cm2. The impedance spectroscopy of this sample allowed us to determine dispersion of dielectric permittivity and conductivity in the range of frequencies of 0.5 Hz–100 MHz. It is stated that the value of the high-frequency dielectric permittivity of films is ε′∞ = 2.8. However, with reduction in the electric field frequency, real and imaginary parts of ε increase to values ∼104–105. Such increase in dielectric permittivity is connected with increase in polarizing caused by accumulation of mobile electric charges (electrons of ions, protons) on boundaries of the structural defects of a film, which are divided by thin dielectric interlayers. The film is solid electrolyte with the ionic conductivity of ∼5 × 10−7 S/cm.

Аннотация:
The transport properties of the TmxMn1–xS (x ≤ 0.15) solid solutions in the temperature range of 200–600 K have been investigated. The temperatures of lattice polaron pinning accompanied by the lattice strain, condensation of the infrared modes, and thermionic emission have been determined. The change of the carrier sign with temperature has been found from the Hall coefficient data and dragging of electrons by phonons, from the thermopower data. The dependence of the magnetoresistance on the concentration, current, and voltage has been established from the I–V characteristics measured without field and in an applied magnetic field of H = 8 kOe in the temperature range of 300–500 K. The functional temperature dependence of the carrier relaxation time has been determined using the impedance data. The concentration region with the magnetoimpedance sign varying with frequency and temperature has been found. The increase in the relaxation time of the induced electric
polarization
with increasing concentration of thulium ions has been observed. The experimental data have been interpreted in the framework of the Debye and Maxwell–Wagner models, as well as the theoretical model for the Rashba spin–orbit interaction.

Аннотация:
As a new localized state of light, the chiral optical Tamm state exists at the interface between a
polarization
-retaining anisotropic mirror and a substance with optical activity. Considering a hybrid structure comprising a metal-free
polarization
-preserving mirror and a cholesteric liquid crystal, we highlight the high Q factor arising from the all-dielectric framework. The intensity of localized light decreases exponentially with increasing distance from the interface. The penetration of the field into the cholesteric liquid crystal is essentially prohibited for wavelengths lying in the photonic bandgap and close to the cholesteric pitch length. The dielectric mirror has its own photonic bandgap. The energy transfer along the interface can be effectively switched off by setting the tangential wave vector to zero. The spectral behavior of the chiral optical Tamm state is observed both as reflection and transmission resonance. This Fano resonance is analogous to the Kopp-Genack effect. Our analytics are well in line with precise calculations, which may pave a new route for the future development of intelligent design for laser and sensing applications.

Аннотация:
The problems of occurrence and experimental identification of topologically nontrivial phases in condensed matter have been reviewed. The results of the study of the effect of strong intra- and interatomic Coulomb interaction on a quantum phase transition with change in the topological index in an ensemble of Hubbard fermions on a triangular lattice have been reported. Nontrivial topology of the phase of coexistence of d + id chiral superconductivity and 120° spin ordering in a system with the triangular lattice has been discussed and the formation of Majorana modes in such a phase has been demonstrated. A cascade of quantum transitions that occurs at the variation of the magnetic field or the electrochemical potential has been analyzed for an open nanowire with the Rashba spin-orbit coupling and the induced superconducting pairing potential. It has been shown that anomalies of magneto- and electrocaloric effects are manifested near such quantum transitions and can be used to experimentally test materials on the existence of topologically nontrivial phases in them. The switching of the spin-polarized current in the topological superconducting phase has been predicted for a semimetal/superconducting wire/semimetal structure in the weak nonequilibrium regime.

Аннотация:
Ferromagnetic insulators are widely employed to induce magnetic phenomena in adjacent layers via proximity effect. This approach could make non-magnetic materials (ranging from silicon to graphene) available for spintronic applications. Eu chalcogenides, EuO in particular, are highly efficient spin generators but suffer from low Curie temperatures. Here, experiments aimed at T-C increase in EuO by its integration with the ferromagnetic metal Gd are reported. The epitaxial bilayers Gd/EuO are synthesized on different substrates and characterized by a combination of diffraction and microscopy techniques. Their magnetic structure - established with magnetization and transport measurements as well as element-selective X-ray magnetic circular dichroism study - comprises coupled magnetic orders of EuO and Gd. EuO is robust against proximity effects - its T-C is still low, increased at most by a few tens of K. Nevertheless, the results encourage further studies of proximity-enhanced ferromagnetism to extend the range of applications of ultrathin layers of EuO in spintronics.

Аннотация:
The photoinduced diode effect has been found in BiMnxFe1-xO3 (0 < X < 0.15) films in the near-infrared and violet spectral ranges in a wide temperature interval. The dependences of the diode effect on temperature, wavelength, and illumination power have been established. The mechanism of the ferroelectric diode has been determined using its I-V characteristics at different illumination powers, optical spectra, far-infrared absorption spectra, and electric polarization hysteresis. The interplay between the photodiode effect and conductivity mechanism has been elucidated. The model of strong Coulomb potential fluctuations and quantum well asymmetry caused by the electric polarization in the film and difference between the times of carrier thermalization and recombination of electrons and holes is proposed.
В пленках феррита висмута BiMnxFe1-xO3 (0< x < 0.15) обнаружен фотоиндуцированный диодный эффект в ближней инфракрасной и фиолетовой областях спектра в широкой области температур. Определена зависимость диодного эффекта от температуры, длины волны, мощности освещения. Механизм ферроэлектрического диода определяется из вольт-амперных характеристик при разных интенсивностях освещения, оптических спектров и спектров поглощения в дальней ИК области, гистерезиса электрической поляризации. Устанавливается связь фотодиодного эффекта с механизмом проводимости. Предложена модель сильных флуктуаций кулоновского потенциала, асимметрия квантовых ям в результате наличия электрической поляризации в пленке и отличие времен термолизации носителей тока и рекомбинации электронов и дырок.

Аннотация:
An optico-mechanical model describing the coherent (directed) transmittance and the degree of
polarization
of forward-transmitted light by a polymer film with elongated liquid-crystal (LC) drops has been developed. This model, based on the Foldy–Twersky and anomalous-diffraction approximations, makes it possible to analyze the optical response of a film under extension as a function of the film thickness, refractive index of the polymer, the sizes and anisometry parameters of liquid-crystal drops, their concentration, internal structure, polydispersity, and orientation of optical axes. The model is verified based on the comparison of numerical and experimental data for the inverse modification of interfacial anchoring by an ion-forming surfactant. The internal drop structure is determined by solving the problem of minimizing the volume free energy density. A comparative analysis of the calculated transmittance and degree of
polarization
for films with uniform homeotropic and modified inhomogeneous interfacial anchoring is performed. The spectral
polarization
characteristics of a film with elongated LC drops and single-domain internal structure, formed under mechanical extension with the aid of surfactants, are investigated. © 2017, Pleiades Publishing, Ltd.
