Electrochemical properties of electrodes on the basis of CH900-20 activated carbon
(AC) cloth were studied in concentrated H 2 SO 4 solutions in a wide range of potentials
from− 0.8 to+ 1 V RHE. Cyclic voltammetric curves measured in two ranges of potentials
were analyzed: in the reversibility range (from 0.1 to 0.9 V) and in the deep cathodic
charging range (from− 0.8 to 1 V). Electric double layer (EDL) charging occurs in the
reversibility range, while faradaic processes of hydrogen chemisorption and its ...

Formation of carbon nanoparticles is an important type of complex non-equilibrium processes that require precise atomistic theoretical understanding. In this work, we consider the process of ultrafast cooling of pure carbon gas that results in nucleation of an onion-like fullerene. The model is based on molecular dynamics simulation with the interaction between carbon atoms described ...

We present a new quantum accurate Spectral Neighbor Analysis Potential (SNAP) machine-learning potential for simulating carbon under extreme conditions of dynamic compression (pressures up to 1 TPa and temperatures up to 10,000 K). The development of SNAP potential involves (1) the generation of the training database comprised of the consistent and meaningful set of first-principles ...

Electrochemical behavior of electrodes on the basis of CH900-20 activated carbon (AC) cloth has been studied in concentrated sulfuric acid solution. Cyclic voltammetric curves have been studied in the reversibility range (from 0.1 to 0.9 V RHE) and in the deep cathodic charging potential range (from –0.8 to 1 V RHE). It has been shown that electric ...

The paper is oriented toward the problem of determination of rheological characteristics of a material by free bulging testing. This information about the material behavior is used for design of gas forming technologies for production of complex shell parts used in aerospace industry. Realization of such technologies requires pressure forming regimes which can be calculated ...

Reaction between monolacunary {BW11} tungstoborate and oxothiocationic building block, {Mo2O2S2}, results in the formation of a new polyoxothiometalate with a unique architecture in which two [H2BW12O43]9− tungstoborate subunits are linked together with a hexamolybdate [MoV6O6S6(OH)4(H2O)2]2+ bridge. ...

Исследовано влияние режимов сильнополевой инжекции электронов на модифицикацию МДП-транзисторов с многослойным подзатворным диэлектриком SiO2 – ФСС, содержащим электронные ловушки. Показано, что для инжекционной модификации МДП-транзисторов более предпочтительным оказывается режим инжекции электронов из кремниевой подложки, при котором выше величина максимального сдвига порогового напряжения и существенно ниже вероятность пробоя подзатворного диэлектрика по сравнению с инжекцией из алюминиевого ...

We investigate the effect of interacting quantum phase slips on persistent current and its fluctuations in ultrathin superconducting nanowires and nanorings pierced by the external magnetic flux. We derive the effective action for these systems and map the original problem onto an effective sine-Gordon theory on torus. We evaluate both the flux dependent persistent current ...

The problem of planar oscillations of a pendulum with variable length suspended on the Moon’s surface is considered. It is assumed that the Earth and Moon (or, in the general case, a planet and its satellite, or an asteroid and a spacecraft) revolve around the common center of mass in unperturbed elliptical Keplerian orbits. We ...

We investigate the influence of quantum phase fluctuations on electron density of states (DOS) in ultrathin superconducting films and nanowires. Using an effective action approach we derive a non-perturbative correction to DOS in such systems. The main effect of phase fluctuations in quasi-two-dimensional films is the appearance of electron states at subgap energies while in ...

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 ...

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 ...

The exciton valley dynamics in van der Waals heterostructures with transition metal dichalcogenide monolayers is driven by the long-range exchange interaction between the electron and the hole in the exciton. It couples the states active in the opposite circular polarizations resulting in the longitudinal-transverse splitting of excitons propagating in the monolayer plane. Here we study ...

We present an exact analytical solution of the nonlinear shallow water theory for wave run-up in inclined channels of arbitrary cross-section, which generalizes previous studies on wave run-up for a plane beach and channels of parabolic cross-section. The solution is found using a hodograph-type transform, which extends the well-known Carrier–Greenspan transform for wave run-up on ...

We theoretically analyze exciton-photon oscillatory dynamics within a homogenous polariton condensate in presence of energy detuning between the cavity and quantum well modes. Whereas pure Rabi oscillations consist of the particle exchange between the photon and exciton components in the polariton system without any oscillations of their quantum phases, we demonstrate that any non-zero detuning ...

Для нелегированных материалов зависимость коэффициента химического распыления от структуры выражено слабо. Коэффициент распыления легированных бором материалов снижается по мере степени его легирования. С помощью растрового электронного микроскопа исследован рельеф поверхности ряда углеродных материалов. ...
