    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.

  • Patent number: 8007757
    Abstract: A method of synthesizing nanostructures. In one embodiment, the method includes the step of heating a reaction mixture at an elevated temperature, T, for a period of time effective to allow the growth of desired nanostructures. The reaction mixture contains an amount, P, of a carboxylate salt and an amount, L, of a fatty acid ligand, defining a molar ratio of the fatty acid ligand to the carboxylate salt, ?=L/P, and a hydrocarbon solvent. The reaction mixture is characterizable with a critical ligand protection, ?, associating with the chemical structure of the carboxylate salt such that when ?<?, the reaction mixture is in a limited ligand protection (LLP) domain, and when ?>?, the reaction mixture is in a sufficient ligand protection (SLP) domain.

  • Publication number: 20110203772
    Abstract: A system and method for performing heat dissipation is disclosed that includes contacting a heat transfer liquid with a heat exchange surface having raised hydrophilic nanoporous nanostructures disposed adjacent a central core upon a substrate. The heat transfer liquid forms a preselected contact angle when placed on the heat exchange surface. The raised nanoporous nanostructures define channels, interconnected pathways, and voids within the nanoporous nanostructures. The nanoporous nanostructures have additional surface irregularities upon the nanostructures themselves. The nanostructures are preferably formed by depositing metal oxides or other materials upon a substrate using a Microreactor Assisted Nanomaterial Deposition (MAND) process.

  • Patent number: 7993541
    Abstract: The present application is directed to the preparation and use of a class of nanoparticles that contain a single Quantum Confined dopant. A QCA nanocrystal comprises of a plurality of host atoms in a nanocrystal of a size of less than 10 nm with a single atom of a dopant (or activator). This single QCA dopant, when confined, becomes polarized and creates a large magnetic-moment in a nanosize host that contains atoms of unpaired spins. The quantum confined atom (QCA) which is now pinned, triggers the alignment of the host atoms resulting in nanosize magnetic domain. Engineering of nanomagnets based on QCA nanoparticles can be used in different applications such as: sensors, drug delivery, bio-tagging, cell/DNA tagging, magnetic memories and others.
