Vernadskii Institute of General & Inorganic Chemistry NAS of Ukraine popup.description2 Methods for preparation of weakly agglomerated nanoparticles of lithium-conductive materials La0.57Li0.33TiO3 and Li1.3Al0.3Ti1.7(PO4)3 by deposition from inverted microemulsions and sol-gel method were developed. A technique for preparation of thick films of lithium-conductive materials with lithium-conductivity >10–4 Ohm/cm, which exceeds the value for commercial Li-NASICON glass ceramics of OHARA manufacturer, was developed. Large-thick high-conductive electrolytic films for new lithium-ion solid-state batteries (ASSBs) are manufactured. The organo-inorganic perovskite films CH3NH3PbI3 prepared from solutions with different ratios of starting reagents were synthesized and their properties were investigated. It has been found that the stability of films increases with the use of polymer (polyvinyl butyral). It has been determined that the sample of organic-inorganic perovskite with a polymer layer is characterized by a smaller diffusion length of the minority charge carriers. The prepared films are promising for the development of efficient solar cells based on them. Composite resonant elements were manufactured, which included a non-magnetic BaTi4O9-ZnO dielectric and a ferrite film based on Ni1-xZnxFe2O4 for use in the ultra-high frequency range. A detailed theoretical explanation of the principles of operation of magnetically controlled composite resonance elements "nonmagnetic high-speed dielectric resonator - magnetic film" and the principle of calculation has been given, common expressions for calculating the frequency shift in composite resonance elements depending on the parameters of the composite components has been found. The described magneto-controlled resonance elements can be used in GSM networks, in radar systems, as an efficient and versatile replacement of traditional non-reciprocal components, such as dynamic filters, high isolation valves and small displacement fields, in heterodyne transmitters.
