Formation of new functional materials and device heterostructures on the basis of nanosystems of superionic conductors

Search for conditions of conservation of fast ionic transport (FIT) in nanosystems of advanced superionic conductors (ASIC)[1-4] and synthesis of new types of device thin-film heterostructures on this basis is a fundamental scientific problem. ASICs (α-AgI, solid electrolytes of the family RbAg4I5, etc. ) are crystals with a record high level of ionic conductivity and a low value of activation energy E～0. 1 eV.     

Rheological Properties and Characteristics of Hydraulic Transportation and Heat-Mass Exchange of Coal-Water Fuels

The procedure is proposed for calculating the characteristics of flow and heat exchange of coal-water fuels as applied to the pipeline hydraulic transport and heat-mass exchange in the apparatus of ecologically clean combustion in the objects of power engineering.     

Control of the coal-rock boundary by elastic vibrations

Conclusions The marked difference between the rates of damping of longitudinal mechanical vibrations in metal rods brought into contact with specimens of coals and rocks gives grounds for assuming that this phenomenon may be utilized for remote discrimination between coals and rocks. This makes it possible to develop a special sensor for automatic control of the direction of movement of heading and extraction machines exactly along the boundary of the coal seam, i.e., along the boundary between the coal and rock.
