The size effects in the structures based on silicon carbide

Conditions for creation of light emitting diodes working in electrical breakdown regime have been determined. The floatable technology have been used. Light emitting diodes obtained is possible to use as standards of power and spectral composition of radiation, and although for creation of sources of short light impulses. Constructions of these devices, laboratorial technology of their fabrication, elements of metrological support have been worked out.
Emitters on SiC-basis operating in the electrical breakdown regime have the following superior characteristics:

Development of theoretical basics, methods and tools for design of modern high speed computer systems in Grid and Cloud systems

A new architectural concept of parallel computing in GRID systems and cloud environment is proposed, which uses FPGA as a high-performance heterogeneous computing resource. FPGA is used as heterogeneous programmable operating unit for processing data streams, allowing for achievement of optimized performance-related energy consumption. The concept simplifies programming the computational problems for these systems.

Dispersion-stabilized hydrocarbon oligomers and their potential for nanospintronics

Spectral, thermal and electronic properties of a new class of hydrocarbon-based materials diamondoid oligomers was investigated. The methods for the selective functionalization of lower and higher diamondoids were developed. Methods of association lower diamondoids in lower oligomers have been developed. X-ray diffraction and thermogravimetric spectra of lower diamondoid oligomers were made. We propose a model that adequately accounts the effects of dispersion interactions in diamondoid oligomers for their physicochemical characteristics.

Development and research of the two-phase medium-temperature thermosyphon for the implementation of the waste streams heat recovery in the pumping units of the gas pipeline

Gas compressor units operate with large thermal emissions (up to 20 MW), high temperature (300 ° C or more) and, at the same time, they require a considerable amount of electricity for the maintenance of the own pumping stations equipment of the Ukrainian gas pipeline. Recycling streams from the high pumping units and outgoing heat conversion into electric energy can be carried out using thermoelectric generators.

Methods of the organization of information-analytical systems for intellectual technology support of system electronic educational resource

A number of approaches and methods was developed for creating of global electronic space monitoring program means. The means allow to quickly actualize professional electronic scientific and educational resources.

Pseudo-regular and special functions and their application to problems of stochastic analysis

The aim of the project was a further development of the theory of pseudo-regular and special functions and their applications to limit theorems of renewal theory, study of asymptotic behaviour of solutions to stochastic and deterministic differential equations, investigation of linear and non-linear models in stochastic analysis, statistics of stochastic processes with long-term and short-term dependence, integral equations and transforms.
In the project:

Development of the process production partially metallized iron-ore burden materials on the base ore-carbonic composition for traditional metallurgical technology

For the reason increasing of metallurgical value charge materials domain production was researched possibility of the reception partly metallize pallets from ore-flux-fuel composition. As main raw material was used iron-ore concentrate Inguleckogo GOKa (64,7 % Fe), with additive coke breeze of fraction 0-3 mm and quicklime, which then mingled and were granulated on plate granulator. Got pellets (with 12-17 % dispersed carbon) after fixing on surface defensive layer by thickness 2,0-2,5 mm from mixture of the concentrate and quicklime (1:1) mingled with solid fuel.

Photobioelectrochemical conversion of wastes and raw material to produce electricity and energy carriers

Three ways of converting waste into energy or electricity are combined in this research. The first way concerns the energy conversion of wastewater organic compounds into hydrogen and electricity in biofuel cells. The second one is based on conversion of solar energy and organic compounds energy with using of inorganic photocathode in biofuel cell to produce hydrogen. The third way concerns the conversion of solar energy and inorganic waste gases on lipids of phototrophic microalgae. This combination of processes allows to convert different wastes into energy carriers and electricity.

Terahertz broadband telecommunications system radio access with Gigabit bandwidth

The principles and hardware / software solutions to build a telecommunication system broadband Internet access with Gigabit bandwidth in the frequency range 128-134 GHz to solve congestion frequency bands used today, a substantial increase in the data rate of wireless radio access systems, and the creation of ultra high radio relay lines of the new generation.

Phase and structural transformations in the composite nanostructural quasicrystalline aluminium alloys under severe plastic deformation, pressure and temperature

On the base of the results determined by using modern physical material science methods scientific principles referred to relationships for combined effect of sever plastic deformation and temperature on diffusive processes, phase transformation, evolution of structure and thermal stability of mechanical properties of nanostructured composite Al alloys reinforced by ultra fine particles of metastable quasicrystalline phases has been developed for the first time.
