New polyglucose was synthesized from uridine diphosphoglucose in the rabbit skeletal muscle fibers by the electron histochemical procedure. It was presumably formed from the substrate by the enzyme UDPglucose glycogen glucosyltransferase activity. The new polyglucose particles were deposited either singly or as strings of beads or as branched strings. Single particles were each different in size and density. The beads arranged in order from the smaller particulates stained faintly to the larger particulates stained more densely with lead.New products of this polyglucose were abundantly deposited in the whole matrices among various organelles in the intermyofibrillar and subsarcolemmic sarcoplasms, suggesting sites of the enzyme.

The technique and equipment for preparing pure La and Ce metals by electrolysis of fused lanthanum chloride and cerium (III) chloride with potassium chloride is given. Preparation of the anhydrous chlorides and the effect of current efficiencies of metal yield are also discussed. (Rev. Metal Lit., 20: No. 8, Aug. 1963)

Die Bildung von kubischem α-MoC 1-x durch Carbonisierung von MoO3 mit Graphit wahrend des Erhitzens im Ar-Plasmabogen wird untersucht.

The formation of cubic molybdenum carbide (α-MoC1−x) by the carbonization of MoO3 with plasma arc was studied. α-MoC1−x including small amounts of hexagonal η-MoC1−x was formed. By the carbonization of the mixture of MoO3 and TiO2 the cubic solid solution of Mo–Ti–C system was formed. These products were superconductors.
