  • Nanomaterial preparation method
    Patent number: 11939220
    Abstract: Described is a method of preparing transition metal nanoparticles on a graphene support, in which a tertiary graphite intercalation compound is provided with intercalated metal ions such that the tertiary graphite intercalation compound comprises a graphene sheet having a negative charge. The graphene sheet is contacted with a transition metal salt to cause reduction of the transition metal salt by the graphene sheet, and to form transition metal nanoparticles. Also described are products arising from the method, and uses of those products.

  • Phenolic-hydrazide compounds and polyolefin compositions stabilized therewith
    Patent number: 5319127
    Abstract: Disclosed are a class of phenolic-hydrazide compounds of diverse structure which are useful as stabilizers for polyolefins. The phenolic-hydrazide compounds inhibit oxidative degradation of polyolefins which is attributable to heat and/or ultraviolet light and is promoted or accelerated by metals, e.g., copper, in contact with the polyolefin.
    Type: Grant
    Filed: September 23, 1993
    Date of Patent: June 7, 1994
    Assignee: Eastman Chemical Company
    Inventors: Richard H. S. Wang, Ping P. Shang, Daniel A. Jervis

    Date of Patent: April 12, 1994
    Assignee: Eastman Kodak Company
    Inventors: Richard H. S. Wang, Ping P. Shang, Daniel A. Jervis
  • Bis(phenolic-amine)quinone compounds and polyolefin compositions stabilized therewith
    Patent number: 5189088
    Abstract: Disclosed is a class of bis(phenolic-amine)quinone compounds which are useful as stablizers for polyolefins. The bis(phenolic-amine)quinone compounds inhibit oxidative degradation of polyolefins which is attributable to heat and/or ultraviolet light and is promoted or accelerated by metals, e.g., copper, in contact with the polyolefin. The compounds also exhibit excellent thermal stability.
