Abstract : Information is given about the results obtained, by the use of an emission microscope, in the field of oxidation studies and of controlled reduction processes, carried out both on organic nuclei (previously deposited from vapour phase on a suitable metallic substratum), and on hematite natural crystals. New results are summarized concerning the electrochemical behaviour of zinc tri-crystals under potentiostatically controlled conditions. A brief account is given of some preliminary tests regarding liquid metal penetration along the grain boundaries of a zinc tri-crystal substratum.
