Report describes a few experiments designed to test the analysis of some systems where chemical energy can be converted to electric energy. From Abstract: "If a chemocouple is defined as an isothermal closed circuit, composed of two or more homogeneous ionic aqueous phases separated by two or more barriers of different sets of ionic transport numbers, we find that a spontaneous electric current flows in the closed circuit."

Abstract. It has been established that heating samples of graphite during exposure in a pile decreases substantially the observed changes in the elastic modulus and electrical resistance caused by the irradiation. The functional relationship between the percentage changes observed and the temperature of exposure resembles the relationship between the final percentage changes and the temperature of heat treatment after exposure (cf. report CC-1668). Anomalous results reported previously for higher temperatures in CC01669 are now shown to be attributable to a destructive influence on the graphite, probably oxidation of samples exposed in air.
