Intensifying the Processes of Polysaccharide Extraction from Plant Raw Materials under the Action of an Electric Current
Surface Engineering and Applied Electrochemistry - Tập 58 - Trang 402-411 - 2022
A. P. Malyushevskaya, V. N. Tsurkin, A. V. Ivanov, A. N. Yushchishina
The article presents the results of the studies into the intensification of the processes of extraction of water-soluble polysaccharides from plant raw materials—medicinal hyssop (Hyssopus officialis L.)—under the action of an electric current. The effect of direct, alternating, and pulsed electric currents on the degree of polysaccharides’ extraction was studied in comparison with the traditional...... hiện toàn bộ
Production of dispersed powders of tungsten-cobalt by spark erosion dispersion of compact samples of hard alloys, including scrap
Surface Engineering and Applied Electrochemistry - - 2015
A. D. Verkhoturov, M. I. Dvornik, T. B. Ershova, A. V. Zaitsev
The processes of the influence of electrical low voltage discharges on compact samples of tungsten-containing hard alloys and the conditions of producing composite powders with a fixed phase and chemical composition and size grading are considered. The obtained results have been used to manufacture dispersed powders of tungsten-cobalt hard alloys by spark erosion dispersion of compact scrap and re...... hiện toàn bộ
Electrolytic binary metal-oxide compounds: Fundamental peculiarities of their structure and formation
Surface Engineering and Applied Electrochemistry - Tập 49 - Trang 368-372 - 2013
V. M. Nagirnyi, R. D. Apostolova, S. V. Petrichenko
Based on the experimental results and the data published in the literature, the specific features and qualitative distinctions of electrolytic binary metal-oxide systems (such as V-Mn, Co-Ni, Co-Cr, Mn-Ni, and Mn-Cr) from the individual oxides contained in them are studied. In a binary system, these oxides react to form a complex structurally homogeneous conglomerate. The precipitates of the binar...... hiện toàn bộ

Peculiarities of Control over Electron-Beam Additive Form Manufacturing
Surface Engineering and Applied Electrochemistry - Tập 55 - Trang 232-240 - 2019
A. V. Shcherbakov, R. V. Rodyakina, A. S. Kozhechenko, N. M. Vakhmyanin, D. A. Gaponova, V. P. Rubtsov
This work analyzes the manufacturing process of an electron-beam additive form by heating as a result of remelting the supplied filler wire as a control object. Control actions and output values are designated that can be used in constructing a control systems with feedback. A mathematical modeling technique is used to study heat transfer in a nonstationary formulation, taking into account the inf...... hiện toàn bộ
Parameters of heterogeneous electron transfer from Hb to pyrollitic graphite in aqueous and non-aqueous media: Rate constants and dispersion of electron hopping distances
Surface Engineering and Applied Electrochemistry - Tập 47 - Trang 544-548 - 2012
V. V. Ivanov, E. V. Ivanova
A novel methodology of multi-exponential kinetic data processing was developed and tested for the reduction of hemoglobin on pyrollytic graphite.
Codiffusion of Gallium and Phosphorus Atoms in Silicon

Effects of Electrolyte Composition on Heat Exchange in Anode Plasma Electrolyte Treatment of Commercial Titanium
Surface Engineering and Applied Electrochemistry - Tập 54 - Trang 136-141 - 2018
A. V. Zhirov, S. Yu. Shadrin, P. N. Belkin
The study considers heat exchange in a three-phase system: electrolyte solution—vapour-gas envelope (VGE)—a titanium workpiece. The temperature of a workpiece, current intensity, heat fluxes from the envelope to the electrolyte and the workpiece were measured in an aqueous solution of ammonium chloride with addition of ammonia and glycerol. Addition of ammonia and glycerol proved to decrease curre...... hiện toàn bộ
