  • Patent number: 9440857
    Abstract: A method of producing pristine graphene particles through a one-step, gas-phase, catalyst-free detonation of a mixture of one or more carbon-containing compounds hydrocarbon compounds and one or more oxidizing agents is provided. The detonation reaction occurs very quickly and at relatively high temperature, greater than 3000 K, to generate graphene nanosheets that can be recovered from the reaction vessel, such as in the form of an aerosol. The graphene nanosheets may be stacked in single, double, or triple layers, for example, and may have an average particle size of between about 35 to about 250 nm.

  • Publication number: 20070166222
    Abstract: An improved process for the production of ultralow density, high specific surface area gel products is provided which comprises providing, in an enclosed chamber, a mixture made up of small particles of material suspended in gas; the particles are then caused to aggregate in the chamber to form ramified fractal aggregate gels. The particles should have a radius (a) of up to about 50 nm and the aerosol should have a volume fraction (fv) of at least 10?4. In preferred practice, the mixture is created by a spark-induced explosion of a precursor material (e.g., a hydrocarbon) and oxygen within the chamber. New compositions of matter are disclosed having densities below 3.0 mg/cc.

  • Publication number: 20050008875
    Abstract: Glass/nanoparticle composites are provided which include a glass matrix with a high density of heterologous nanoparticles embedded therein adjacent the outer surfaces of the composite. Preferably, the glass matrix is formed of porous glass and the nanoparticles are yttrium-iron nanocrystals which exhibit the property of altering the polarization of incident electromagnetic radiation; the composites are thus suitable for use in electrooptical recording media. In practice, a glass matrix having suitable porosity is contacted with a colloidal dispersion containing amorphous yttrium-iron nanoparticles in order to embed the nanoparticles within the surface pores of the matrix. The treated glass matrix is then heated under time-temperature conditions to convert the amorphous nanoparticles into a crystalline state while also fusing the glass matrix pores.

  • Publication number: 20030207949
    Abstract: A method of forming ligated nanoparticles of the formula Y(Z)x where Y is a nanoparticle selected from the group consisting of elemental metals having atomic numbers ranging from 21-34, 39-52, 57-83 and 89-102, all inclusive, the halides, oxides and sulfides of such metals, and the alkali metal and alkaline earth metal halides, and Z represents ligand moieties such as the alkyl thiols. In the method, a first colloidal dispersion is formed made up of nanoparticles solvated in a molar excess of a first solvent (preferably a ketone such as acetone), a second solvent different than the first solvent (preferably an organic aryl solvent such as toluene) and a quantity of ligand moieties; the first solvent is then removed under vacuum and the ligand moieties ligate to the nanoparticles to give a second colloidal dispersion of the ligated nanoparticles solvated in the second solvent. If substantially monodispersed nanoparticles are desired, the second dispersion is subjected to a digestive ripening process.
