The most significant results
The patterns of complexation processes involving polyhedral anions BnHn2- (n = 10,12), their halogen derivatives and the isomerization, dimerization and redox reactions accompanying these processes were established.
A new concept of functionalization of polyhedral anions BnHn2- (n = 10,12), based on the spatially aromatic character of these systems, has been proposed and developed, which made it possible to carry out directional synthesis of the substituted these anions with theoretically and practically important properties.
New approaches to the synthesis of highly dispersed components of the component base have been developed and implemented to create ultrahigh-temperature HfB2 / xSiC ceramic ceramics - silicon carbide, super high-melting carbides and oxides, which has significantly optimized the technology of ceramocomposites and their quality.
The physicochemical and structural transformations in the HfB2 / xSiC ceramocomposites under the influence of high-enthalpy dissociated air flows were studied, which made it possible to increase the stability of the composite under these conditions.
New heterometallic complexes of Pd – Ag with trifluoroacetate ligands and toluene were synthesized and investigated, and their transformation into a seventeen-nuclear complex with replacement of toluene with water was established.
Methods have been developed for the synthesis of new nanoscale organomineral materials based on calcium hydroxyapatite and biopolymers for bone implants with improved physicochemical and biomedical properties, and the effect of biopolymers on the size, morphology and solubility of materials has been studied.
