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
Electrolytic binary metal-oxide compounds: Fundamental peculiarities of their structure and formationSurface 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
Size effect of microhardness of nanocrystalline Co-W coatings produced from citrate and gluconate solutionsSurface Engineering and Applied Electrochemistry - Tập 51 - Trang 228-234 - 2015

The influence of various electrodeposition conditions (current density, including volume current density, and hydrodynamic conditions in different electrode systems such as the Hull cell with a rotating cylinder electrode and a cell without stirring, including a soluble anode (W) and an insoluble anode (graphite)) on the microhardness of nanocrystalline Co-W coatings, obtained from citrate and glu...... hiện toàn bộ
On the simulation of a corona discharge by the similarity theory methodsSurface Engineering and Applied Electrochemistry - Tập 50 - Trang 141-148 - 2014
F. P. Grosu, An. M. Bologa, M. K. Bologa, O. V. Motorin
A general system of equations for a corona discharge has been derived and reduced to a dimensionless form using the methods of the similarity and dimension theory. Criteria and conditions for the similarity of the processes occurring during a corona discharge have been determined. Formulas for free space-charge density have been derived; the classical structure of the current-voltage characteristi...... hiện toàn bộ
(AgxCu1 – x)2ZnSnS4-Based Thin Film Heterojunctions: Influence of CdS Deposition MethodSurface Engineering and Applied Electrochemistry - Tập 57 - Trang 323-329 - 2021

Cu2ZnSnSe4 (CZTSe) based solar cells, containing abundant elements, with Ag alloying have recently reached efficiency of 10.2%. The open circuit voltage in CZTSe devices is believed to be limited, in between other factors, by strong band tailing caused by an exceptionally high density of Cu/Zn antisites. By replacing Cu in CZTSe with Ag, whose covalent radius is 15% larger than that of Cu and Zn, ...... hiện toàn bộ
