 The purpose of the research was to create the scientific basis for the synthesis of compounds and substances for modern technologies for the production of new-generation chemical current sources, drugs for biomedical use, and structural materials. As a result of the conducted research, the fluoride-conducting phase Pb0.43Ba0.43Sn1.14F4 was synthesized and investigated for the first time, which, compared to the currently known solid fluoride-conducting electrolytes, has the highest (0.12 C/cm at 373 K) electrical conductivity in a wide temperature range. A method of modifying polymeric proton-conducting cation-exchange materials with a two-component modifier, which includes stanium hydrogen phosphate (IV) and carbon quantum dots, has been developed. This allows to significantly expand the operating temperature range of their operation. A condensation method for the preparation of finely dispersed, nanostructured cathodic Pt/C electrocatalysts and anode Ir and Ir/SnOx is proposed, which allows to reduce the consumption of precious metals by 10% without worsening the specific energy characteristics of hydrogen-acid fuel cells. It was found that the inhibitory activity of hafnium phthalocyanines on amyloid protein aggregation decreases in the order PcHfPiromelit > PcHfCl2 > PcHfPyr2 > PcHfBtfa2. Of the studied out-of-plane coordinated zirconium phthalocyanines, the highest inhibitory activity was observed for PcZrLys2. The use of a constant magnetic field during the electrodeposition of molybdenum and tungsten alloys from citrate-pyrophosphate electrolytes helps to increase the current yield of the alloys compared to deposition under natural convection conditions. The fundamental possibility of creating lithium-ion batteries with a composite electrolyte based on a porous ceramic LATP matrix impregnated with a 1M solution of LiPF6 in a mixture of ethylene carbonate and dimethyl carbonate is shown. The proposed composite electrolyte allows solving the problems of lithium
