  • Aluminum based alloy containing cerium and graphite
    Patent number: 11408056
    Abstract: The present invention provides an aluminum hybrid metal matrix composite including cerium and graphite. The aluminum-cerium intermetallic is stable at temperatures up to a melting point of aluminum and graphite provides in situ lubrication. This stability is advantageous in applications such as cylinder liners and other applications where strength and stiffness at elevated temperatures are required.
    Type: Grant

  • Process for preparing 2-thiouracil nucleosides
    Patent number: 3975374
    Abstract: Some new 1-(2- or 3-deoxy-.beta.-D-pentofuranosyl)-2-thiouracils and 1-.beta.-D-pentofuranosyl-2-thio-6-azauracils have been prepared. Further, it has been found that the known nucleoside compound, 1-.beta.-D-ribofuranosyl-2-thiouracil is active against Herpes virus and against L-1210 leukemia in mice. An improved method of preparing corresponding 2-0-methyluracil and 2-0-methyl-6-azauracil intermediates is described. The method preserves the .beta.-configuration of the starting nucleoside.
