The effect of a high-power pulsed flow of deuterium ions and deuterium plasma generated in a plasma focus setup on the surface structure of a Ti plate was investigated. It was established that, depending on the radiation-thermal conditions on the surface, three zones with different surface morphology, structure, and defects were formed in the surface ...

We studied structure and thermodynamic properties of cubic and tetragonal phases of pure uranium and
U-Mo alloys using atomistic simulations: molecular dynamics and density functional theory. The main
attention was paid to the metastable g0-phase that is formed in U-Mo alloys at low temperature.
Structure of g0-phase is similar to body-centered tetragonal (bct) lattice with displacement of a ...

We study analytically and numerically the distribution of granular temperatures in granular mixtures for
different dissipation mechanisms of inelastic inter-particle collisions. Both driven and force-free systems
are analyzed. We demonstrate that the simplified model of a constant restitution coefficient fails to
predict even qualitatively a granular temperature distribution in a homogeneous cooling state. At the
same time we reveal ...

Описаны принципы работы безапертурного сканирующего микроскопа ближнего оптического поля (ASNOM). Зондом в приборе служит металлизированная игла атомно-силового микроскопа, и оптическое взаимодействие с объектами на поверхности локализовано вблизи ее острия размером в несколько нанометров. Тело иглы имеет длину в несколько микрон, и это обеспечивает высокую эффективность ее электромагнитного взаимодействия с падающими на нее извне и излучаемыми ...

Spectral characteristics of WSi and NbN superconducting single-photon detectors with different surface resistance and width of nanowire strips have been investigated in the wavelength range of 1.3-2.5 µm. WSi structures with narrower strips demonstrated better performance for detection of single photons in longer wavelength range. The difference in normalized photon count rate for such structures ...

Theoretical models of the conformational behavior of flexible polymer chains in mixed solvents enunciated in the world literature during the last decade are critically reviewed. Models describing different mechanisms of coil-to-globule transitions in a good solvent induced by cosolvent addition are highlighted. Special attention is given to the analysis of theoretical approaches to describing the ...

We have studied and optimized conditions for spontaneous flux growth of TbCr3(BO3)4 crystals.
Phase relations in the pseudoternary system TbCr3(BO3)4–K2Mo3O10–B2O3 have been studied in the temperature
range 900–1130°C and the single-phase terbium chromium borate crystallization field has been
mapped out. It has been shown that increasing the TbCr3(BO3)4 content of the starting high-temperature
solution leads to a rhombohedral-to-monoclinic phase ...

The integer quantum Hall effect is a well-studied phenomenon at frequencies below about 100 Hz. The plateaus in high-frequency Hall conductivity were experimentally proven to retain up to 33 GHz, but the behavior at higher frequencies has remained largely unexplored. Using continuous-wave terahertz spectroscopy, the complex Hall conductivity of GaAs/AlGaAs heterojunctions was studied in the ...
