Abstract: Process for producing nanomaterials such as graphenes, graphene composites, magnesium oxide, magnesium hydroxides and other nanomaterials by high heat vaporization and rapid cooling. In some of the preferred embodiments, the high heat is produced by an oxidation-reduction reaction of carbon dioxide and magnesium as the primary reactants, although additional materials such as reaction catalysts, control agents, or composite materials can be included in the reaction, if desired. The reaction also produces nanomaterials from a variety of other input materials, and by varying the process parameters, the type and morphology of the carbon nanoproducts and other nanoproducts can be controlled. The reaction products include novel nanocrystals of MgO (percilase) and MgAl2O4 (spinels) as well as composites of these nanocrystals with multiple layers of graphene deposited on or intercalated with them.

Abstract: Process and apparatus for functionalizing and/or separating graphene particles and other nanomaterials in which graphene and other nanoparticles are placed in a pile on one of two opposing conductive surfaces that are charged with a high D.C. voltage so that material of a certain character is attracted to the other conducting surface. This process takes place in an enclosed chamber that has been flooded with a designated gas at ambient pressure, with the material attracted to the second conducting surface passing through the designated gas. The high energy field creates a condition such that the material remaining on the first conductive surface takes on atoms of the designated gas and material the going to the second surface is further exposed to and characterized by the designated gas.

Abstract: Graphene composite material and devices using the same. The graphene is dispersed in material such as polyurethane, latex, other elastomers, and other polymers to produce a composite material having high heat transfer properties which make it particularly suitable for use in removing heat from LEDs and other electronic devices. Several examples of heat transfer devices utilizing the material are disclosed.
