Physicochemical bases of low-temperature synthesis (700 - 1500 оС) of ultra-refractory high-strength reinforced ceramics and metal-ceramics of multifunctional application

An integrated approach to the creation of scientific physicochemical foundations of the process of synthesis of large polycrystalline samples or products of reinforced ceramic high-temperature materials at low temperatures is implemented, which involves the use of a capillary-porous body with predetermined structural-geometric characteristics of pore channels as a medium for growing fibers reinforcement (the first at the level of separately taken powder particles from which a capillary-porous t is made) ceramic composite.

Theoretical and experimental investigations of electronic, magnetic and optical properties of nanosized carbon-containing materials

Luminophores of “white light” are an important part of white-light-emitting diodes, and the main part of these diodes consists from UV light sources (usually an InGaN based light-emitting structure) and a luminophor transforming UV into a broad spectrum of white light. To date, rare earth or heavy metals are the main components of luminophors leading to its recycling complexity and increase in manufacturing costs. Moreover, the spectral characteristics of the modern commercial luminophors do not correspond to the spectral characteristics of the sunlight.

Creation of methods for designing the processes of shaping engineering structures under viscoplastic deformation of homogeneous, eutectic strengthened and powder materials

In this work, using a unified theoretical approach, the analysis of the processes of visco-plastic forming of typical mechanical engineering structures with homogeneous and structurally heterogeneous materials.

Effects of electromagnetic interaction in microwave multipleplaced planar structures and development of the theory of filters for telecommunication system

A theory has been developed for multi-tiered bandpass filters of a planar structure, its position is confirmed by measurements on existing experimental samples. On the basis of the established theoretical positions, new circuit design solutions for bandpass filters with different frequency characteristics have been created, which is reflected in the patent materials. It is established that three- resonator filters with a mixed cross-coupling K 13 = K m + K e , equal to zero (К 13 = 0), have two equidistantly located damping poles or a constant delay time.
