Аннотация: Fe K-edge x-ray magnetic circular dichroism of magnetite (Fe(3)O(4)) powders was measured with synchrotron radiation under variable pressure and temperature conditions in diamond anvil cell. The magnetic dichroism was observed to decrease discontinuously by similar to 50% between 12 and 16 GPa, independent of temperature. The magnetic transition is attributed to a high-spin to intermediate-spin transition of Fe(2+) ions in the octahedral sites and could account for previously observed structural and electrical anomalies in magnetite at this pressure range. The interpretation of x-ray magnetic circular dichroism data is supported by x-ray emission spectroscopy and theoretical cluster calculations.

Аннотация: A new model of the electron pressure anisotropy in the electron diffusion region in collisionless magnetic reconnection is presented for the case of antiparallel configuration of magnetic fields. The plasma anisotropy is investigated as source of collisionless dissipation. By separating electrons in the vicinity of the neutral line into two broad classes of inflowing and accelerating populations, it is possible to derive a simple closure for the off-diagonal electron pressure component. The appearance of these two electron populations near the neutral line is responsible for the anisotropy and collisionless dissipation in the magnetic reconnection. Particle-in-cell simulations verify the proposed model, confirming first the presence of two particle populations and second the analytical results for the off-diagonal electron pressure component. Furthermore, test-particle calculations are performed to compare our approach with the model of electron pressure anisotropy in the inner electron diffusion region by Fujimoto and Sydora [Phys. Plasmas 16, 112309 (2009)]. (C) 2010 American Institute of Physics. [doi:10.1063/1.3521576]

Аннотация: Experimental values of the Lorentz tensor components L-j for uniaxial quasi-two dimensional "soft matter" objects on substrates (bilayer lipid membranes, multilayer Langmuir films, smectics A, hexatic smectics B, submicron films of discotics Col(hd), micron anisotropic films of liquid-crystal comblike polymers and macromolecular polymers, submicron films of conjugated conductive polymers), freely suspended sub-micron films of smectics A, and uniaxially stretched micron films of conjugated conductive polymers have been determined using dispersion of refractive indices in the visible range. The dependences of the components L-j on the type of orientation (axial, planar) of uniaxial molecules (structural units of the film) with respect to the optical axis of the film, the film thickness, the substrate type, the chemical structure of molecules, and their long-range orientational order are established. It is revealed that the smectic A-hexatic B phase transition and two-dimensional crystallization of the smectic layer lead to changes in the components L-j due to the change in the orientational ordering of molecules as a result of the relation between the orientational and hexatic order parameters. All the above objects are characterized by isotropization of the Lorentz tensor L and the local-field tensor f with a simultaneous decrease in the birefringence of the sample and in the anisotropy of the molecular polarizability due to the change in the electronic structure of molecules. The correction for the anisotropy of the local-field tensor f to the orientational order parameter or the anisotropy of the molecular polarizability increases. The existing model approaches to calculating the components L-j for the objects under consideration are compared with the experimental data.

Аннотация: Light transmission spectrum of a multilayer photonic crystal with a central liquid-crystal defect layer placed between crossed polarizers has been studied. Transmittance was varied due to the magnetically induced reorientation of the nematic director from homeotropic to planar alignment. Two notable effects were observed for this scheme: the spectral shift of defect modes corresponding to the extraordinary light wave and its superposition with the ordinary one. As a result, the optical cell allows controlling the intensity of interfering defect modes by applied magnetic field. (C) 2010 Optical Society of America

Аннотация: Atomic and electronic structure and energetic stability of newly proposed pentagonal and hexagonal chiral complex silicon nanowires (NWs) composed of five or six (I 10) oriented crystalline fragments were studied using the ab initio DFT method. The chirality of the wires was caused by consecutive shifts of each fragment by 1/5 or 1/6 of the wire unit cell parameter and rotations of 4 degrees and 3.3 degrees for achiral pentagonal or hexagonal wires, respectively. Chirality causes the HOMO-LUMO gap to reduce by 0.1 eV. Chiral silicon nanowires are found to be metastable structures with a 4,5 (kcal/mol)/Si atom potential barrier for reversible chiral achiral transformation.

Аннотация: The structures of two phases of the (NH4)3Nb(O2)2F4 crystal, namely, the parent cubic phase and the most distorted low-temperature phase, have been determined from data of an X-ray diffraction experiment performed for a powder sample. The profile and structural parameters have been refined according to the procedure implemented in the DDM program. The results obtained have been discussed with invoking the group-theoretical analysis of the complete order parameter condensate, which takes into account the critical and noncritical atomic displacements and allows the interpretation of the obtained experimental data. It has been found that the most probable sequence of structural transformations occurring in the crystal can be schematically represented in the following form: Fm3¯m−→−−−−(η1,η1,η)Γ+5(11−7)C2/m−→−−−−−−−−−−−−−−−−(η1,η1,η)(0,0,0,0,0,ξ,0−ξ,0,0,0,0)Γ+5(11−7)⊗Σ2(4−2)P21/m−→−−−−−−−−−−−−−−−−−−−−−−−−−−−−(η1,η1,η)(0,0,0,0,0,ξ,0−ξ,0,0,0,0)(0,0,0,0,0,ε,0,ε,0,0,0,0)Γ+5(11−7)⊗Σ2(4−2)⊗Σ3(4−3)P21/n.\begin{gathered} Fm\bar 3m\xrightarrow[{(\eta 1,\eta 1,\eta )}]{{\Gamma _5. + (11 - 7)}}C2/m\xrightarrow[{(\eta 1,\eta 1,\eta )(0,0,0,0,0,\xi ,0 - \xi ,0,0,0,0)}]{{\Gamma _5. + (11 - 7) \otimes \Sigma _2 (4 - 2)}}P2_1 /m \hfill \\ \xrightarrow[{(\eta 1,\eta 1,\eta )(0,0,0,0,0,\xi ,0 - \xi ,0,0,0,0)(0,0,0,0,0,\varepsilon ,0,\varepsilon ,0,0,0,0)}]{{\Gamma _5. + (11 - 7) \otimes \Sigma _2 (4 - 2) \otimes \Sigma _3 (4 - 3)}}P2_1 /n. \hfill \\ \end{gathered}

Spin-glass freezing -- Transition metal ludwigites
Аннотация: The single crystal needle shape samples of diamagnetically diluted cobalt ludwigite CoMgGaO2BO3 have been grown by the flux method. The results of x-ray diffraction and both dc and ac magnetic measurements are presented. The unit cell volume undergoes a noticable growth under dilution from 328.31 Å3 for the parent compound Co3O2BO3 to 345.46 Å3 for CoMgGaO2BO3. The temperature of magnetic transition is considerably lower for the latter compound (25 K against 43 Kfor Co3O2BO3). The dc magnetization temperature dependencies undergo the splitting of field cooled and zero-field cooled regimes and the ac magnetic susceptibility temperature dependencies are frequency dependent pointing out a possible spin-glass freezing in the magnetic system.

Аннотация: We investigate the electrooptical characteristics of a cell based on a nematic liquid crystal layer controlled with the use of modification of the surface anchoring by an ionic surfactant. The inverse mode of the effect is used with the nematic oriented homeotropically in the initial state and transferring to the hybrid homeoplanar structure in an applied dc electric field. We consider the applied voltage dependences of the dynamic parameters of the optical response. В© 2013 Pleiades Publishing, Ltd.

Autotrophic synthesis -- Cupriavidus eutrophus -- Polyhydroxyalkanoates
Аннотация: Synthesis of polyhydroxyalkanoates (PHAs) by a new strain of Cupriavidus - Cupriavidus eutrophus B-10646 - was investigated under autotrophic growth conditions. Under chemostat, at the specific flow rate D=0.1h-1, on sole carbon substrate (CO2), with nitrogen, sulfur, phosphorus, potassium, and manganese used as growth limiting elements, the highest poly(3-hydroxybutyrate) [P(3HB)] yields were obtained under nitrogen deficiency. In batch autotrophic culture, in the fermenter with oxygen mass transfer coefficient 0.460h-1, P(3HB) yields reached 85% of dry cell weight (DCW) and DCW reached 50g/l. Concentrations of supplementary PHA precursor substrates (valerate, hexanoate, ?-butyrolactone) and culture conditions were varied to produce, for the first time under autotrophic growth conditions, PHA ter- and tetra-polymers with widely varying major fractions of 3-hydroxybutyrate, 4-hydroxybutyrate, 3-hydroxyvalerate, and 3-hydroxyhexanoate monomer units. Investigation of the high-purity PHA specimens showed significant differences in their physicochemical and physicomechanical properties. В© 2013 Elsevier Ltd.

Аннотация: A one-dimensional asymmetric photonic crystal with dual-frequency liquid crystal as a central defect layer was demonstrated. Such asymmetric structure was characterized by the dramatic increase in intensity of the electric field of light localized at the overlapped photonic bandgap edges, thereby enhancing the observed transmittance of the spectral windows originating from the defect layer. The defect layer was made of a dual-mode liquid crystal that exhibited not only electrical tunability and switchability but also optical bistability. Consequently, tunable and bistable defect modes can be realized in the photonic structure. This asymmetric photonic crystal structure is promising and should be further explored for photonic device applications. (C) 2014 Optical Society of America

Аннотация: This study is concerned with the optical response of an electro-optical material consisting of nematic liquid crystal as well as ionic surfactant as a dopant. The dopant is a key component to carry out the working of the resulting device through configuration switching. The operational principle is based on the surface anchoring transition induced by a steady electric field. The dynamic characteristics of the electro-optical cell can be considerably improved when the nematic layer is reoriented from the initially homeoplanar director configuration into the twisted state. Besides, a method to shorten the relaxation time is demonstrated by using a controlling pulse with a bipolar waveform. (C)2014 Optical Society of America

КОАКСИАЛЬНЫЙ ВОЛНОВОД -- ДИЭЛЬКОМЕТРИЯ -- КСВН -- ИЗМЕРИТЕЛЬНАЯ ЯЧЕЙКА -- COAXIAL WAVEGUIDE -- PERMITTIVITY MEASUREMENT -- VSWR -- MEASURING CELL
Аннотация: Рассмотрено несколько вариантов конструкции коаксиальных ячеек, рассчитанных на работу в линии передачи с волновым сопротивлением 50 Ом и предназначенных для измерения комплексной диэлектрической проницаемости дисперсных и жидких материалов в диапазоне частот от 0.01 до 16 ГГц. Проведено численное моделирование коаксиальных ячеек с использованием метода конечных разностей во временной области. Проанализировано распространение ТЕМ-волны через ячейки и рассчитаны их S-параметры. Выполнен сравнительный анализ рассмотренных ячеек и сделаны выводы о возможности их использования для проведения точных измерений комплексной диэлектрической проницаемости в диапазоне частот от 0.01 до 16 ГГц. Рассмотрены особенности различных вариантов конструкции коаксиальной ячейки с точки зрения технической реализации. Приведены экспериментальные результаты коэффициента стоячей волны напряжения для одного из вариантов предлагаемых конструкций. Наблюдается хорошее согласование экспериментальных данных с результатами численного моделирования в диапазоне частот 0.01-12 ГГц. Расхождение модельных и экспериментальных данных в диапазоне частот 12-16 ГГц можно объяснить погрешностями в геометрии ячейки и конечной проводимостью используемых проводников.
Some variants of coaxial measuring cells for 50 Ohm line and complex permittivity measurements of liquid and disperse matters in 0.01-16 GHz frequency band has been considered. Numerical modeling using finite difference method in time domain has been carried out. TEM-wave propagation through cells has been analyzed and S-parameters were calculated. Comparative analysis of considered cells has been carried out. Conclusions about its application to complex permittivity measurement in frequency band 0.01-16 GHz has been formulated. Technical features of arbitrary variants have been considered. Experimental results of the voltage standing wave ratio for one of the variants of the proposed designs have been presented. Good agreement between the experimental data and the results of numerical modeling in a frequency band 0.01-12 GHz is observed. The disagreement between the model and experimental data in the frequency band 12-16 GHz can be explained by the errors in the cell geometry and the finite conductivity of the conductors.
