The resulting CMs have high thermal stability. The optimal conditions for synthesis of bulk and supported Ni-Co catalysts for the reaction of methanation of CO2 were determined. The oxide systems based on Se, Co and Mn that were synthesized by citrate sol-gel method are catalytically active in CO oxidation and selective oxidation of CO in the presence of H2 and multi-systems show higher activity than single-component ones. The patterns of influence of 1,2,4-triazole to 4-amino-1,2,4-triazole ratio on morphology, size and characteristics of the spin transition of nano-objects of mixed-ligand complexes of iron (II) were revealed. Some new nano-objects and nanocomposites that exhibit spin transition phenomenon were obtained. A four-stage temperature regime of formation of nanosized SnO2 (8 nm) with optimal sensor characteristics was worked out and temperature conditions for creation of sensors based on nanomaterials SnO2, SnO2-Sb2O5, Pd/SnO2-Sb2O5 and Pd/SnO2 were proposed. A new sensor material based on SnO2 with reproducible and acceptable electrical resistance value of corresponding sensors in air and their sensitivity to 40 ppm H2 was obtained. The priority role of energy disparity of interactions in Al-Fe and Fe-Ge pairs in the structure formation of the ternary melt Ge-Al-Fe on the background of the weak interaction in the Al-Ge pairs was established. The partial and integral enthalpies of mixing of ternary Ce-Cu-Sb melts along two sections of constant molar ratio of Cu and Sb at 1723 K was determined. Melts of this system are formed with considerable heat release. Product Description popup.authors Іщенко О.В. Бєда О.А. Безугла Т.Н. Головата Н.В. Гріщенко Л.М. Гуральський І.О. Діюк В.Е.
