[en] Distribution of sulfuric acid electrolyte components over oxide films on aluminium, titanium and tantalum prepared by anodic oxidation in sparking mode has been studied by the methods of X-ray phase and X-ray diffraction analyses. It has been proved that sulfur compounds are incorporated into composition of the coatings produced. The sizes of channels where sulfur involvement occurs have been estimated by recording patterns. Numerical values of the channels obtained by the authors are in a good agreement with literature data. 5 refs.; 4 figs

[en] It was shown that as a result of radiation coagulation, a quantitative isolation of albumin from irradiated aqueous solutions is possible. The coagulation of albumin is induced by OH radicals, the action of which on the albumin macromolecules leads to a breakdown of intramolecular bonds and to conformational conversions of albumin

[en] Gamma radiation effect on 0.1-0.5%-albumin aqueous solutions has been investigated; variations of viscosity and optical density of solutions at pH medium different values and completeness of protein separation owing to radiation coagulation have been determined. It is shown that due to radiation coagulation it is possible to quantitatively separate albumin from irradiated aqueous solutions. The albumin coagulation is caused by OH radicals the action of which on albumin macromolecules results in destruction of intramolecular bonds and albumin conformation transformations

[en] The spectrum of visible and near-UV luminescence due to a microdischarge on an AMg-6 aluminum alloy was studied under conditions of valve anodization in solutions of sodium carbonate and other electrolytes. It was shown that emission spectra exhibit lines that characterize anodic (aluminum and magnesium) and electrolytic (sodium) components. The dependence of the temperature of the microdischarge on the electrolyte concentration and composition is discussed
