THE SEMICONDUCTOR FILM AT THE BASE OF GALLIUM POLYPHOSPHATE, SYNTHESIZED BY THE METHOD OF SOLID-PHASE REACTION

Gallium polyphosphate was synthesized using the method of solid-phase reaction between Ga(NO3)3 and NH4H2PO4. Some properties of gallium polyphosphate and compound on its basis, such as index of refraction, density, conduct- ivity were studied. New composition of semiconductor film is developed, and the properties semiconductor film at the base of gallium polyphosphate

OPTIMISATION OF AUTOMOBILE ANTIFREEZE COMPOSITIONS

A quantum chemical study of the structure and stability of such antifreeze components as water and glycol has been undertaken using ab initio method in DZV basis. It is shown, that if ratio of water and glycol is optimal, decreasing of temperature leads to self-organization in the molecular level and structuring of water- spirit mixture and conversion to the solid state in low temperature (-75 оС)
