Аннотация: Using electro- and magneto-optical techniques, we investigated orientational transitions in the ensembles of domains in a nematic liquid crystal on the polycarbonate film surface under the conditions of competing surface forces that favor radial and uniform planar alignment of nematic molecules. Having analyzed field dependences of the intensity of light passed through a sample, we established the threshold character of the orientational effects, plotted the calculated intensity versus magnetic coherence length, and compared the latter with the equilibrium length that characterizes the balance of forces on the polymer surface.

Аннотация: On the basis of an unbiased structure prediction, it is shown that the stable form of NiSi under pressures of 100 and 200 GPa is the Pmmn structure. Furthermore, a new stable phase has been discovered: the deformed tetragonal CsCl-type structure with a = 2.174 Å and c = 2.69 Å at 400 GPa. Specifically, the sequence of high-pressure phase transitions is the following: the Pmmn structure below 213 GPa, the tetragonal CsCl type in the range 213–522 GPa, and cubic CsCl higher than 522 GPa. As the CsCl-type structure is considered as the model structure of the FeSi compound at the conditions of the Earth's core, this result implies restrictions on the Fe–Ni isomorphic miscibility in FeSi.

10 angstrom phase -- talc -- water transport -- subduction
Аннотация: The synthesis of 10 angstrom phase via the reaction of talc plus water at 8 GPa and 500 degrees C was studied by in situ Raman spectroscopy using a diamond-anvil cell. The initial fast (2 h) incorporation of interlayer H2O molecules into the talc structure is traced by gradual growth of new OH stretching bands at 3592 and 3621 cm(-1) and the shift of several framework bands. Further monitoring at HP-HT conditions over 7 h reveals gradual weakening of the 3592 cm(-1) band, which can probably be related to the onset of the formation of "long-run" 10 angstrom phase through the appearance of silanol groups following the model proposed by Pawley et al. (2010), influencing the interlayer hydrogen bonding.

Solid-phase synthesis of solid solutions in Cu/Ni(001) epitaxial nanofilms / V. .

Аннотация: Solid-phase synthesis of solid solutions in the epitaxial Cu/Ni(001) bilayer film systems of compositions 3Cu: 1Ni, 1Cu: 1Ni, and 1Cu: 3Ni has been studied using the X-ray diffraction methods. The saturation magnetization and the magnetic crystallographic anisotropy constant on nickel vary in accordance with the solid solution formation. The initiation temperature of the solid solutions is about 350 A degrees C and is independent of the Ni: Cu layer thickness ratio. The solid-phase synthesis of the solid solutions is presumably attributed to the transport of the Cu atoms to the epitaxial Ni(001) layer. It is found that the solid-phase synthesis in the Cu/Ni bilayer nanofilms and multilayers is determined by the spinodal decomposition in the Cu-Ni system.

An analysis of the mechanism of Kerr effect enhancement in Mn/Dy/Bi / S. G. Ovchinnikov [et al.] // Phys. Solid State. - 1999. - Vol. 41, Is. 1. - P. 80-86, DOI 10.1134/1.1130733. - Cited References: 35 . - ISSN 1063-7834

Аннотация: A study is reported of the structural, magnetic, and magneto-optic properties of Mn/Dy/Bi films obtained by multilayer technology. The maximum Kerr rotation angle in such films is shown to be theta(k) = 2.25 degrees. Possible reasons for such a large Kerr effect enhancement are considered, namely, an increase in the 6p - 3d transition probability caused by symmetry distortion, polarization of the Bi6p band, and a change in the density of states near the Fermi level. The latter reason has been analyzed by simulating the electronic structure of Mn/Dy/Bi through superposition of Dy levels on the MnBi band structure. This approach has revealed possible additional transitions which may be induced by the presence of a Dy buffer and could contribute to the Kerr magneto-optic effect.

Аннотация: Long nonlinear two-dimensional traveling waves on a film driven by laminar gas flow are investigated numerically via solving Navier-Stokes equations. The evolution of their shape, amplitude, and speed with increasing Reynolds number is studied. The existence of solitary waves is demonstrated. A comparison between shear driven and gravity-capillary waves is made and discussed. It is shown that shear driven waves as compared to gravity driven waves are much higher for equal film Reynolds numbers and much slower for equal wave amplitudes.

Аннотация: The electronic, magnetic, and optical properties of MnGa2O4 in the structure of the normal and inverse spinels are subjected to an ab initio investigation and comparison. The generalized gradient approximation (GGA) predicts that the normal MnGa2O4 spinel is a semiconductor with a bandgap of about 0.7 eV, and a bandgap in the structure of the inverse spinel appears only in terms of the GGA + U approach. A simple exchange interaction model is used to calculate exchange integrals. In both structure types, MnGa2O4 exhibits antiferromagnetic behavior, and the normal structure is energetically favorable. The inverse spinel becomes energetically favorable only when a negative pressure is applied. The absorption spectra of the normal spinel are found to have a spectral window at a wavelength larger than 450 nm.

Аннотация: The incorporation of impurity ions or doping is a promising method for controlling the electronic and optical properties and the structural stability of halide perovskite nanocrystals (NCs). Herein, we establish relationships between rare‐earth ions doping and intrinsic emission of lead‐free double perovskite Cs2AgInCl6 NCs to impart and tune the optical performances in the visible light region. Tb3+ ions were incorporated into Cs2AgInCl6 NCs and occupied In3+ sites as verified by both crystallographic analyses and first‐principles calculations. Trace amounts of Bi doping endowed the characteristic emission (5D4→7F6‐3) of Tb3+ ions with a new excitation peak at 368 nm rather than the single characteristic excitation at 290 nm of Tb3+. By controlling Tb3+ ions concentration, the emission colors of Bi‐doped Cs2Ag(In1−x Tbx )Cl6 NCs could be continuously tuned from green to orange, through the efficient energy‐transfer channel from self‐trapped excitons to Tb3+ ions. Our study provides the salient features of the material design of lead‐free perovskite NCs and to expand their luminescence applications.

Аннотация: В данной работе был изучен процесс восстановления растворов Ag (I) цитратными комплексами Fe (II), который позволяет получать наночастицы серебра с высокой стабильностью и концентрацией более 60 г/л. В ходе работы было установлено влияние скорости введения, скорости перемешивания, концентрации реагентов, рН среды и некоторых постсинтетических операций на средний размер наночастиц. Показано, что снижение концентрации Ag (I) и повышение концентрации стабилизатора, доведение рН реакционной среды до 7 позволяют получать наиболее мелкие и однородные частицы. В результате были найдены оптимальные условия, которые дали возможность уменьшить размер частиц и вместе с тем снизить концентрацию реактивов на 33 %. По данным РФЭС, ПЭМ, DLS и ИК были получены наночастицы металлического серебра с размером 6.5±1.8 нм, стабилизированные продуктом частичного распада цитрат-иона.
The reaction of reduction solution of Ag (I) by Fe (II) citrate complex was studied herein. This allows you to receive silver nanoparticles with high stability with a concentration above 60 g/l. It was determined that the nanoparticles size depends on the injection rate, mixing rate, reagent concentration, pH and some post-synthetic operations on the average size of nanoparticles. It was shown that decreasing the concentration of Ag (I) and increasing the concentration of stabilizer also bringing pH to 7 lead to small and uniform particles. Optimal conditions were found that made it possible to reduce particle size and reduce the concentration of reagents by 33 % in the results. According to XPS, TEM, DLS and FTIR datas, nanoparticles of metallic silver with a size of 6.5±1.8 nm were obtained, which stabilized by the product of partial decay of the citrate ion.
