CHEMICAL PROBLEMS

Abstract One of the promising technological processes in the production of oils is the hydrocracking process. It is radical in destructive hydrogenation and change in the structure of raw material molecules to obtain oil products with new qualities that are absent in the original raw material. The hydrocracking process in the processing of oil fractions […]

Abstract New Zn(II) and Cd(II) complexes with a hydrazone based on (E)-N'-(5-bromo-2- hydroxybenzylidene)nicotinohydrazide (HL) were obtained. The structures of these complexes were studied using infrared (IR) spectroscopy, Electronic (UV–Vis) spectroscopy, derivatography, luminescence spectroscopy, and elemental analysis. It was established that Zn(II) forms a complex with the ligand (HL) in a metal-to-ligand ratio of M:L = […]

Abstract As the global energy landscape shifts toward more sustainable and high-performance storage solutions, the development of next-generation supercapacitor electrodes has become increasingly critical. Addressing this demand, we developed a straightforward chemical co-precipitation method to synthesize manganese dioxide (MnO2) and cobalt oxide (Co3O4), incorporating a conductive carbon framework as a potential electrode material for supercapacitors.
