    Ultrananocrystalline Diamond
    Technology that covers a suite of critical semiconductor processes, formation of circuit elements to create complex circuits, and the integration of electronic circuits that are built on a single semiconductor base material or single chip that could revolutionize the electronics industry and creating more durable and efficient products.

    Graphene Films
    Suite of one-atom-thick graphene materials that drastically reduce the wear rate and the coefficient of friction (COF) of steel. Estimated reduced loss of energy to friction offered by new materials would yield a potential energy savings of 2.46 billion kilowatt-hours per year, equivalent to 1.5 million barrels of oil.

  • Slippery when dry

    Anyone who has ever taken their car in for an oil change recognizes the importance of reducing the friction that arises when steel touches steel.
    graphene-encapsulated diamond ball bearings
  • A method for coating a dielectric substrate with a R-GO film includes positioning the dielectric substrate in a chamber which is purged with a first gas to adjust a pressure of the chamber to a first pressure

    US Patent 10,351,429 B2
    • Direct Synthesis of Reduced Graphene Oxide Films on Dielectric Substrates (ANL-IN-14-110)

    A second gas at a second flow rate and a third gas at a third flow rate is inserted into the chamber to increase the chamber pressure to a second pressure greater than the first pressure. A chamber temperature is increased to a first temperature. The flow of the second gas and the third gas is stopped. The chamber is purged to a third pressure higher than the first pressure and lower than the second pressure. The pressure of the chamber is set at a fourth pressure greater than the first pressure and the third pressure. A fourth gas is inserted into the chamber at a fourth flow rate for a first time.
