Application of graphenes in supercapacitors (review)
Volfkovich Y.
Аннотация

This review examines the literature, mainly of recent years, on the current topic of using graphenes in supercapacitors. The influence of the porous structure of graphenes, the influence of doping and irradiation of graphenes are considered. Methods for producing graphenes, composites of graphenes with metal oxides, sulfides and selenides, with metal particles, with electron-conducting polymers, with MXenes, as well as quantum dots are considered. Electrochemical characteristics are given for the types of graphene considered.

Oxygen-ion and proton transport in Y3+-doped hexagonal perovskite Ba7In6Al2O19
Animitsa I., Andreev R., Korona D., Gilev A., Nokhrin S.
Аннотация

In this work, the thermal and electrical properties of the Y3+-doped Ba7In5.9Y0.1Al2O19 phase, characterized by a hexagonal perovskite structure (a = 5.935(7) Å, c = 37.736(8) Å), were studied. It has been established that the phase is capable of incorporating protons and exhibiting proton conductivity. The introduction of an isovalent dopant, yttrium, led to an increase in the concentration of protons (up to the limiting values of Ba7In5.9Y0.1Al2O19 ·0.55H2O), as a result of an increase in the unit cell volume and, accordingly, the free space for the placement of OH-groups in an oxygen-deficient block containing coordination-unsaturated polyhedra [BaO9]. Isovalent doping led to an increase in the oxygen-ion conductivity, which is due to an increase in interatomic distances and a decrease in the migration activation energy. In a humid atmosphere (pH2O = = 1.92·10–2 atm), the Ba7In5.9Y0.1Al2O19 phase exhibited higher values of proton conductivity compared to the matrix compound Ba7In6Al2O19 and below 500°C it was characterized by dominant proton transport both in air and in a wide range of pO2 (10–18–0.21 atm).

Influence of metallophilic interactions on physicochemical properties of ion-conducting glass systems (1-x)(0.27Sb2Se3–0.73GeSe2)-xAg2Se
Tomaev V., Tverjanovich Y., Lunkov S., Zaitseva S.
Аннотация

The influence of silver selenide concentration on plasticity, microfate and softening temperature interrelationship, energy of metal atoms in chalcogenide system (1-x)(0.27Sb2Se3–0.73GeSe2)-xAg2Se was presented. Particular attention is paid to a multiple increase in plasticity with an increase in silver selenide content in chalcogenide glasses. The observed effects are associated with the formation of metallophilic interactions of silver-silver. The studies are supplemented by the results of impedancemetry, due to the fact that metallophilic interactions in chalcogenide glass can actively influence not only the glass transition temperature, but also many other important properties, including the mechanism of electronic and ion conductivity.

Consolidation of al and Ta-substituted Li7La3Zr2O12 powders with lithium-ion conductivity by spark plasma sintering
Kunshina G., Bocharova I., Belov A., Shichalin O., Papynov E.
Аннотация

Monophase powders of cubic modification with nominal composition Li6.4Al0.2La3Zr2O12 (Al–LLZ) and Li6.52Al0.08La3Zr1.75Ta0.25O12 (Ta–LLZ) were synthesized. Dense (~97–98%) ceramic samples of solid electrolyte with increased stability in air were obtained from these powders by spark plasma sintering. High Li-ion conductivity (4–6×10–4 S/cm) corresponding to the world level have been achieved.

Inhibitory protection of low carbon steel in a flow of phosphoric acid solution containing iron (III) phosphate
Avdeev Y., Panova A., Andreeva T.
Аннотация

The corrosion of low carbon steel in a flow of H3PO4 solutions containing FePO4, including media with additives of mixture of corrosion inhibitors consisting of a 3-substituted derivative of 1, 2, 4-triazole (IFKhAN-92) and KNCS, was studied. In the discussed medium, partial reactions of anodic ionization of iron, cathodic reduction of H+ and Fe (III) cations are realized on steel. The first two reactions are characterized by kinetic control, and the last one is diffusion-controlled. The accelerating effect of FePO4 on steel corrosion in a H3PO4 solution is mainly due to the reduction of Fe (III). In inhibited acid, the accelerating effect of Fe (III) cations affects all partial reactions of steel. Despite such an accelerating effect, the mixtures of IFKhAN-92 and KNCS retain a high inhibitory effect on the electrode reactions of steel, which is an important result. The data on corrosion of low carbon steel in the flow of the studied media, obtained from the mass loss of metal samples, are in satisfactory agreement with the results of the study of partial electrode reactions. The accelerating effect of FePO4 on steel corrosion in the flow of H3PO4 solutions, including in the presence of inhibitors, is noted. In these media, steel corrosion is determined by the convective factor, which is typical for processes with diffusion control. Mixtures of inhibitors IFKhAN-92 + KNCS provide significant slowdown of steel corrosion in the flow of H3PO4 solution containing FePO4, which is the result of its effective slowdown of all partial electrode reactions of the metal.

Anodic dissolution and corrosion of Al in KOH solutions in 90% ethanol containing additives of gallium and indium compounds. Inhibitory effect of citric acid
Rybalka K., Beketaeva L.
Аннотация

The influence of addition of citric acid monohydrate on anodic dissolution and corrosion rate of aluminium in KOH solutions in 90% ethanol containing additives of gallium and indium compounds has been considered. It is shown that the introduction of citric acid monohydrate into the solution allows to reduce the magnitude of aluminium corrosion current without reducing the rate of its anodic dissolution. The inhibition efficiency of citric acid monohydrate when introduced into the solution at a concentration of 5∙10–4 M is 58%. The discharge galvanostatic curves in the above electrolyte show a flat discharge plateau up to a discharge current density of 16 mA/cm2.
