06 Electrical power supply and utilization (scientific, technical) the polarization potential is built up at the interface. The high dielectric constant of ferroelectric films also enhances dipole polarization, substantially improving the Hz gas-induced polarization potential. The results obtained f
In Japanese) Derived from petroleum or coal heavy oils, carbonaceous materials or resin powders are impregnated with metal compounds such as nitrates, chlorides and hydroxides and then carbonized and graphitized to give partially graphitized crystalline carbonaceous materials as the battery anodes.
New hydrated cobalt-substituted nickel hydroxides were prepared and characterized. These materials were obtained either by precipitation (a) or by the "chimie douce" technique (a\* and a'). Cobalt generally stays in the trivalent state. In contrast with the aco~+ phases, the aco,\* phases are stable
