The development of energy-efficient technology of isostatic graphite production

Energy efficient technical solutions and regulations of pressing, baking and graphitizing of isostatic graphite artifacts were developed, which do not have any analogues in Ukraine and enable specific energy consumption decrease. Parameters of material base for isostatic graphite artifacts obtaining were determined and the requirements for “green” isostatic graphite samples, which are obtained on the pressing stage, were formulated.

The functional and biocompatible composition coverages formation on Ti- and Fe-alloys, with hardened by carbon nanotubes and intrusion elements, at the terms of extreme power influences

For the first time the scientific basis of a fundamentally new method of forming biocompatible (titanium alloy) coating of carbon nanotubes (CNT) in polycrystalline silicon oxide layers with nickel and iron catalytic centers are obtained by CVD for implants, dentures support-the driving apparatus of human and medical instruments were developed. For the first time a model of physical and chemical processes of the composite coatings formation under laser irradiation of CNT substrates with pre-coated with a layer of hydroxyapatite powder were proposed.

Nanosized metal oxides: synthesis, structure, physico-chemical and electrochemical properties, applications.

It is known that substances with crystal size less than 100 nm possess some valuable properties which are not known for the substances in bulk or macrocrystal state. In particular, nanosized metal oxides become electrochemically active, which permit to use them in energy storage systems.

The conditions for the reactions of oxidation of metals (titanium, tin, tantalum) and their compounds were determined for the synthesis of the nanosized oxides.
