PHYSICAL AND CHEMICAL RESEARCH INTO (2Bi2O3·B2O3)100-x – (2 Bi2O3·3GeO2)x SYSTEM AND ELECTROPHYSICAL PROPERTIES OF OBTAINED ALLOYS
Abstract The paper presents the results of studies into physical-chemical and electrophysical properties of alloys of the (2Bi2O3·B2O3)100-x – (2 Bi2O3·3GeO2)x system. Frequency dependences of electrical impedance (R), dielectric permittivity (ε') and dielectric losses (tg σ) in alternating current and different temperatures were studied. It found that in samples the conductivity is mainly hopping conductivity […]

CATALYTIC HYDROGEN PRODUCTION SYSTEMS FOR PORTABLE POWER APPLICATION
Abstract In this short review article summarizes the results of studies of catalytic and photocatalytic systems for the production of hydrogen from metal borohydride and ammonium boranes. Their performance and the main problems for the usage in portable power sources such as polyelectrolyte membrane fuel cells (PEMFC) are discussed.
