Karazin Kharkiv National University popup.description2  Experimental and theoretical study of the processes of rare nuclear decays, the interaction of plasma with the surface and interfacial interaction in nanoscale systems have been carried out. New solutions of boundary value problems of electrodynamics about excitation, radiation, diffraction of electromagnetic waves in complex volumes with nonlinear impedance structures are obtained, which makes it possible to increase the efficiency of electronic and radio engineering systems. The properties of solids (electroconsolidated Fe-Ni composites, FeSe iron-containing superconductors, nanostructured ZnO, ZnO:In and CuI thin films) have been studied to create functional materials with predetermined characteristics. Research has been carried out in the field of astrometry, stellar astronomy and extragalactic astronomy, objects and processes in the near and far space, the database on the absolute magnitudes of asteroids has been supplemented with new data, and three catalogs of extragalactic sources have been created. Comprehensive research has begun on: the solvation effect on the stability of nanodiamonds, optimal conditions for creating ion-molecular systems for electrochemical applications; new means of sample preparation; on the synthesis and study of functional 3 substituted derivatives of coumarin; complexing ability of promising organosilicon materials; new radical ion salts with complex complex and cluster metal anions. Physico-chemical research of fluorescent dyes and metal-fluorophore indicators for materials science, environmental screening was carried out; methods of analysis of micro and macroelements, heavy toxic metals, radioactive isotopes have been improved. Fundamental research in geometry has been carried out. Іnfological model of the ecological cluster of the geospatial data infrastructure of the Kharkiv region has been formed. Studies of the demographic, labor resource and settlement potential of new administrative-territorial units of Ukraine have been Product Description popup.authors Achasov Andriy B. Bobkov Valentyn V.
