  • Publication number: 20150068446
    Abstract: A method of producing silicon carbide is disclosed. The method comprises the steps of providing a sublimation furnace comprising a furnace shell, at least one heating element positioned outside the furnace shell, and a hot zone positioned inside the furnace shell surrounded by insulation. The hot zone comprises a crucible with a silicon carbide precursor positioned in the lower region and a silicon carbide seed positioned in the upper region. The hot zone is heated to sublimate the silicon carbide precursor, forming silicon carbide on the bottom surface of the silicon carbide seed. Also disclosed is the sublimation furnace to produce the silicon carbide as well as the resulting silicon carbide material.

  • Publication number: 20150064451
    Abstract: A coating method, coated article and coating are provided. The coated article includes a low temperature component, and a graphene coating formed from a graphene derivative applied over the low temperature component. The coating method includes providing a graphene derivative, providing a low temperature component, applying the graphene derivative over the low temperature component, and forming a graphene coating. The graphene coating reduces corrosion and fouling of the low temperature component. The coating includes a graphene derivative, and modified functional groups on the graphene derivative. The modified functional groups increase adherence of the coating on application to a low temperature component.

  • Publication number: 20150064442
    Abstract: A method of rapidly fabricating a graphene-based nanocomposite using oxidation-reduction and a graphene-based nanocomposite fabricated by the same method. A solution in which a graphene oxide is dispersed is prepared. A source material for a metal oxide is added into the solution in which the graphene oxide is dispersed. A nanocomposite is formed by forming the metal oxide on at least one surface of graphene that is reduced using oxidation-reduction between the graphene oxide and the source material for the metal oxide. The reduction voltage of the source material for the metal oxide is 1.0 V or less.
