A model was developed to determine the residual life of structural elements with short cracks under the action of cyclic strain and a corrosive environment. Borate glasses activated by lanthanide ions were synthesized for white LEDs. The relaxation mechanisms of electronic excitations and the nature of exciton states in bulk and nanoscale CeF3 crystals were estimated. Based on first-principle calculations within the electron DFT, the effect of impurities on the electronic structure and physical properties of ZnO-based nanostructures and their potential application in nanoelectronic and spintronic devices was assessed. New organic fluorophores based on heterocyclic compounds, suitable for the construction of OLED devices, were predicted and synthesized. New intermetallic compounds were synthesized, phase equilibria were established, isothermal sections of state diagrams were constructed, quantitative characteristics of chemical and physical properties of compounds were determined for chemical compositions corresponding to optimal structural, electrokinetic, magnetic and thermoelectric properties. The distribution of hydrogen flows through the soil layer within the sedimentary basins of the Western oil and gas region was established. Concepts of natural hydrogen migration in sedimentary basins and methods of hydrogen leakage mapping based on soil gas composition variations were developed. The unique characteristics of the fluvial terrain and processes in a pivotal zone affected by various river confluences in the Sukil River basin within the Skole Beskids have been identified. Their role in river system function amid climate change and human impact on the environment has been assessed.
