The main professional interests of Dmitry Moskovsky are related to the use of self-sustaining chemical reactions, the so-called phenomenon of “solid flame” or self-propagating high-temperature synthesis, for the synthesis of ceramic and metal nanopowders; study of the fundamental principles of their sintering and consolidation in order to obtain new materials. He is also involved in examining the direct synthesis of ceramic nano-structured materials and products by combining the processes of gasless combustion and spark plasma sintering.
Main results:
The bulk phase of high-entropy nitride (Hf0.2Nb0.2Ta0.2Ti0.2Zr0.2) N was obtained for the first time by the method of exothermic combustion. The manufactured bulk material demonstrates ultra-high hardness (33 GPa) and crack resistance (5.2 MPa m1/2), thus significantly exceeding the values of previously obtained binary and high-entropy ceramics (Fig 1). This high-entropy nitride may be used for superhard coatings, structural materials, optics, etc. The results obtained illustrate a scalable method for obtaining bulk high-entropy nitrides with new reference properties.

Ultra-high-temperature ceramics HfCN with the highest theoretical melting point among all currently known compounds were obtained. The melting points of the synthesized compound and the initial “record holder” — hafnium carbide were compared. To do so, pressed HfC and HfCN samples were placed on a graphite plate in the form of a dumbbell and covered with a similar plate on top to avoid heat losses. The resulting “sandwich” was connected to a powerful battery using molybdenum electrodes. All tests were carried out in high vacuum. Since the cross-section of the graphite plates varied, the maximum temperature was reached in its narrowest part. The results of simultaneous heating of the new material, carbonitride and hafnium carbide, showed that carbonitride has a higher melting point than hafnium carbide (Fig. 2).
Due to the unique combination of physical, mechanical and thermal properties, the material is promising for use in the most heat-loaded components of aircraft — nose cones, air-jet engines and sharp leading edges of the wings, operating at temperatures above 2000 °C.

The graphene — Cu and graphene — CuNi nanocomposites were prepared by the solution combustion. Such materials are characterized by a graphene-metal nanostructure with the number of graphene layers from 1 to 3 nm and metal grains 31 nm (Cu) and 14 nm (CuNi) in size. Experimental data showed that the graphene-metal nanocomposites obtained are one of the most efficient catalysts for CO oxidation with a temperature of 100% conversion of 150 °C and 200 °C for Cu and CuNi-containing catalysts, respectively. In this case, both nanopowders turned out to be inactive with respect to the destruction of dyes.
Dmitry Moskovskikh received a scholarship from the president on the topic of self-propagating high-temperature synthesis of thermoelectric materials. The project is aimed at creating a new method for producing advanced thermoelectric materials for the power industry of the future by the method of controlled energy-efficient combustion synthesis and spark plasma sintering. To solve the problem, it is expected to do the following: create and optimize methods of synthesis by combustion of nanostructured Heusler alloys Fe2Ti1-x SnVx and Fe2TiSn1-xSix; conduct a detailed study of nanostructures depending on the synthesis conditions; determine relationships between the structure and physical properties for the manufacture of materials with the increased ZT parameter. This task is an integral part of pending issues of the energy industry of the future, the development of scientific foundations for the production of thermoelectric materials.
