The research in aimed on the synthesis and elucidation of physical properties of new inorganic and organic compounds, solid solutions and polymer composites based on them, which can be used to develop new materials for energy conversion and storage and in other areas of functional electronics. In particular, for the registration and conversion of electromagnetic emission into light and other energy sources, for the development of new economical fluorescent sources, high-speed ionizing radiation detectors, photovoltaic converters, the development of electrodes for lithium, sodium and metal hydride materials. magnets, magnetic refrigerators, heterogeneous catalysts, structural and protective elements with extreme thermal and mechanical properties, sorbents with high gravimetric and volumetric capacity, materials of superconductors in a wide temperature range with high critical currents. Increasing the efficiency of prospecting for new deposits of coarse-grained graphite, a key component for the manufacture of modern batteries. The study of the geoenvironment is aimed at assessing its current state, functioning and dynamics in the context of climate change and growing anthropopression in order to preserve it, its rational use and protection. Find out the methods of numerical modeling of the formation of protogalaxies (halo), the dependence of their luminescence in rotational-oscillating transitions of the first molecules H2, HD and HeH+ on the parameters of dark matter and dark energy models, which are fundamental, dominant in density, components of the universe sensitive tests of such models based on observations of millimeter radio astronomy.

For the first time, the global signal intensity in the energetic levels of the first molecules from the Dark Ages was estimated. The integration time for detecting the global signal in the atomic H 21 cm line against the background of galactic synchrotron radiation was calculated. Optimal size ratios of components were established to enhance the energy characteristics of new supercapacitor-based batteries. A new exact solution for a black hole in the Horndeski theory was found. A relativistic model of a particle invariant under deformed Poincaré symmetry was presented. Mathematical models for assessing the impact of operational degradation of materials on the residual resource of structures under corrosive and hydrogenating environments were developed. The CsPbCl₃ single crystals photoluminescence doped with Yb and Er was studied. The quantum yield of Er luminescence (524 nm) confirms the high probability of electron transitions to upper energy levels. The impact of doping on the properties of ZnO-based nanoclusters was evaluated. A Ga-In-Sn composite with nanoparticles has been proposed for flexible electronics. The properties of oxide glasses for IR shielding can be adjusted by varying annealing temperature and duration. New organic compounds with TADF, RTP, AIEE effects, ambipolar semiconductivity, and solvatochromism were obtained, and OLED devices with a quantum efficiency exceeding 10% were constructed. New intermetallic compounds were synthesized, quantitative characteristics were determined to select compositions corresponding to optimal physical properties. Anomalous hydrogen values were recorded for the first time within the Western oil and gas region. Areas with anomalously high hydrogen content in soil gas were mapped. New data from a study of the model basin of the Bystrytsia Tysmenytska River was obtained, with cartographic schemes of geosystem components created and probable changes in climate parameters within sub- basins calculated.
