Abstract: The invention relates to the purification and disinfection of air and water. A photocatalytic element consists of sintered glass beads with a pore volume fraction from 20% to 40% and a pore size from 0.1 to 0.5 mm, the surface of which is coated with a titanium dioxide powder, having a specific surface area of 150-400 m2/g, at the rate of 0.5-2% relative to the total mass of the photocatalytic element. The surface of the glass beads has a relief shape with a relief depression of 0.5-10 ?m. The method for producing the photocatalytic element comprises sintering the glass beads at a temperature that is 5-20° C. higher than the glass softening temperature, modifying the bead surface with chemical etching agents, and coating the bead surface with the titanium dioxide powder from a water suspension at a pH of 2.9±0.1.

Abstract: The invention relates to electroluminescent materials containing organic luminescent substance. The inventive novel electroluminescent material comprises an electron injecting layer, an active luminescent layer based on a luminescent substance, a hole-transport layer and a hole-injecting layer. The material contains metallocomplexes of quinoline-sulfanylamine derivatives in the form of a luminescent substance. The inventive electroluminescent material exhibits the increased time resource, resulting from the high resistance of the active luminescent layer to crystallisation and hydrolysis, and the high heat resistance of the hole-transport layer.
