Diffusion of acid and alkaline salt solutions through the Nernst diffusion layerRussian Journal of Electrochemistry - Tập 45 - Trang 1193-1197 - 2009
N. P. Gnusin
The behavior of diffusion layer under the conditions of salt transfer with excess of acid or alkali, involving the hydrogen and hydroxyl ions, is studied. The transfer is affected by the applying of current. The method of investigation was mathematical simulation based on the solving of boundary problems by using the Nernst-Planck equation with regard to the corresponding conditions of the transfe...... hiện toàn bộ
Interaction between Thallium and the Au(111) Surface. Quantum-Chemical AnalysisRussian Journal of Electrochemistry - Tập 54 - Trang 912-921 - 2019
N. A. Rogozhnikov
The interaction between thallium atoms and the Au(111) surface is studied using the cluster metal surface model and the density functional method. An adsorbed thallium atom forms a strong chemical bond with surface gold atoms. The adsorption energy barely depends on the location of the thallium atom. The electron density is appreciably displaced from thallium to gold in the process of adsorption. ...... hiện toàn bộ
Electrocatalysis of the Oxygen Reaction by Pyropolymers of N4 ComplexesRussian Journal of Electrochemistry - Tập 40 - Trang 1174-1187 - 2004
M. R. Tarasevich, K. A. Radyushkina, G. V. Zhutaeva
Results of research into structural and electrocatalytic properties of metalloporphyrins and metallophthalocyanines pyrolyzed on carbon supports of various dispersion degree in the oxygen electroreduction reaction (OER) are analyzed. The pyrolysis products (pyropolymers) that form at T ≤ 800°С in inert atmosphere contain centers Co(Fe)–N surrounded by carbon particles. The oxygen electroreduction ...... hiện toàn bộ
Synthesis and electrochemical properties of composites based on carbon nanotubes and polyanilineRussian Journal of Electrochemistry - Tập 47 - Trang 1125-1128 - 2011
E. P. Koval’chuk, A. P. Tomilov, A. I. Krupak, Ya. S. Kovalyshyn
composites made of polyaniline and multiwalled carbon nanotubes have been electrochemically synthesized. The modification of multiwalled carbon nanotubes by a salt of phenyldiazonium significantly increases the redox currents of the polyaniline matrix in the composite. As a result of modification, the conformational state of polyaniline macrochains changes, leading to changes in the morphology, st...... hiện toàn bộ
Nonlinear Impedance of Liquid In–Ga Electrode in Aqueous Solutions of a Symmetrical Surface-Inactive ElectrolyteRussian Journal of Electrochemistry - - 2001
V. V. Emets, V. Ya. Mishuk, B. B. Damaskin, V. V. Elkin, B. M. Grafov
Experimental data related to the potential dependence of nonlinear characteristics of the electrical double layer at a liquid In–Ga electrode in aqueous solutions of a symmetrical surface-inactive electrolyte are obtained for the first time. It is shown that, as opposed to polycrystalline Cd and Pb electrodes, on a liquid (atomically smooth) In–Ga electrode, as on Hg, there is a clear intersection...... hiện toàn bộ
Electrochemical properties of 1-butyl-3-methylimidazolium bromide melt containing water impuritiesRussian Journal of Electrochemistry - Tập 44 - Trang 1257-1262 - 2008
E. P. Grishina, A. M. Pimenova, L. M. Ramenskaya, O. V. Kraeva
The effect of a water impurity (1.8–10 wt %) on the conductivity of the ionic liquid-H2O binary system was studied in a wide temperature range. It was shown that the interaction between components is characteristic of this system, and the molar ratio of components 1: 1 is boundary between the structures of solution and melt. The basic kinetic features of electrochemical reduction of water of the B...... hiện toàn bộ
Direct electrochemical behavior of the Cysteamine/DNA/SWNTs-film-modified Au electrode and its interaction with taxolRussian Journal of Electrochemistry - Tập 44 - Trang 1052-1057 - 2008
Wang Xing Cheng, Dai Yin Peng, Chuan Hua Lu, Cheng Wu Fang
The Cysteamine/DNA/SWNTs-film-modified Au electrode was successfully prepared, and its electrochemical behavior is investigated by cyclic voltammetry (CV). The modified electrode exhibited a pair of stable and well-defined redox peaks, with the formal potentials (E
