Head of Laboratory, Dr. of Science (Chemistry), Academician of RAS

  • Synthesis, structure, and reactivity of spatially aromatic boron cluster structures and metal hydride phases.
  • Synthesis, structure, and properties of new platinum and transition metal complexes.
  • Synthesis, structure, and physicochemical properties of new high-temperature ceramic materials and ceramic composites.
  • Streamlined synthesis of implant materials based on biocompatible calcium phosphates to apply in medicine.

The regularities of complexation processes involving polyhedral anions [BnHn]2– (n = 10, 12) and their halogen derivatives, and isomerization, dimerization, and redox reactions accompanying these processes were established.

A new concept of functionalization of the polyhedral anions [BnHn]2– (n = 10, 12) was suggested and developed based on the spatially aromatic nature of these systems, allowing for the streamlined synthesis of substituted anions with theoretically and practically important properties.

New approaches to the synthesis of highly dispersed components to produce ultrahigh-temperature HfB2/xSiC ceramic composites, namely silicon carbide, ultra-fusible carbides, and oxides, were developed and implemented, thereby significantly optimizing the technology of ceramic composites and their quality.

The physicochemical and structural transformations in HfB2/xSiC ceramic composites under the effect of highly enthalpy flows of dissociated air were studied, making it possible to increase the stability of the composite under these conditions.

New Pd–Ag heterometallic complexes with trifluoroacetate ligands and toluene were synthesized and researched, and their conversion to a 17-nuclear complex upon the replacement of toluene with water was established.

Methods for the synthesis of new nanoscale organomineral materials based on calcium hydroxyapatite and biopolymers for bone implants with improved physicochemical and biomedical properties were developed, and the effect of biopolymers on the size, morphology, and solubility of materials was studied.
