-  The multilevel morphological going is near a construction and synthesis of the difficult technical systems.

-  Application of framework thecal constructions of the bearings systems.

-  Aggregate-module principle of arrangements.

Development and investigation of perspective miniature energy saving devices on based of evaporating - condensation cycle.

Analysis of literature sources had shown that up-to-date state of miniaturization of electronic devices needs the development of new small-size cooling systems, which are capable to reject great heat fluxes. Within the bounds of this problem theoretical ground of advisability of using miniature heat pipes, thermosyphones and oscillating heat pipes in cooling systems for a wide range of powerful elements of microelectronic technics was found.

Investigation of the processes and development of high efficiency resource-saving ecological-safety technology of deep arsenic removal from water

The information about both, natural and anthropogenic ways and the reasons of arsenic compounds appearance in natural waters are generalised. Prevailing forms of the presence of arsenic compounds in water medium are defined. The comparative analysis and summarization of the existing information on the novel methods and materials for deep extraction of arsenic from water are carried out.

Scientific and technological government a structure and properties of castings multicomponent alloys of the system of Al-Mg bases.

On the basis of undertaken analytical and experimental studies intercommunication is set between chemical, phase and structural composition, technological parameters of treatment and level of properties of casting multicomponent alloys of the system Al - Mg.

Highselective resonant-tunneeling crystal-like signal processing devices.

Nanoelectronic signal processing devices based on crystal-like structures are the newest element base of information and telecommunication systems. Resonant-tunneling crystal-like structures and devices based on them with very high spectral selectivity are proposed. High-performance microwave microstrip signal processing devices are developed. To improve the efficiency crystal-like structures used in the modes conventional tunneling - resonant tunneling. Together, these effects provide maximum decoupling of signals in the passband and stopband.

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.

Structure building in technical dispersions under lockal change of hydrophilic-hydrophobic balance of clay surface by functional additives.

The analysis of modern state of the problem is pointing on the main obstacle to the achievement of technical dispersions with a constant mould properties, basic structure building properties of which are clay minerals, is the non-conrolled change of their physico-chemical properties under the effect of SAC in concentration and processing.

The last is a main cause for a unpredictable effect on the formation of coagulation-absorbtion structure and, as the consequence, unpredictable change of technological properties of dispersions.

Applied system analysis and system engineering of information-communication systems

The essence of this development is applying the systems analysis and systems theory for determination of system criterion for dividing the informatization projects not on a functionality feature,  but on some general system features. This allows to formulate the component process of realization of projects of the organizational systems informatization as the specification of certain actions in the form of coordinated implementation of successive and parallel operations on the development of informatization project.

Development of discrete mathematical models of mixing and forming processes at preparation of new polymeric compositions.

The discrete mathematical models of processes of mixing at the unisothermal flow of fusions of polymeric compositions in the mixers ducting of static and dynamic types taking into account the change of their rheological properties from a deformation-temperature condition is developed. A method of the numeral computations of mixing processes of polymer fusions with other components in the mixers ducting of base configurations of extrusion and molding equipment is developed.

Resource-safe synthesis technology and finish treatment of high-temperature bearing materials on the basis of tool manufactures wastes.

There were processed new methods of using valuable secondary resources – grinding wastes of tool manufactures – steels Р6М5, Р6М5К5, Р6М5Ф3 for manufacturing effective composite sliding bearings of high-temperature using. New resources-safe technologies of synthesis and finish grinding of bearing composite from new materials have been developed.
