  • Publication number: 20160369197
    Abstract: Nickel-containing carbon nanofiber (NiCNF) materials and lubricants comprising the nanofiber materials are described herein. The NiCNF materials comprise a plurality of elongate nickel-containing carbon nanofibers. Each NiCNF comprises a carbon nanofiber shaft that is capped at one end by a nickel nanoparticle encapsulated in multiple layers of graphitic carbon. The nanofibers typically have a generally circular cross-section (i.e., in the direction perpendicular to the length-axis of the fibers). The NiCNF materials as useful, e.g., in lubricant compositions, which also are described herein.

  • Patent number: 9441178
    Abstract: This invention relates to carbon-based materials as anti-friction and anti-wear additives for advanced lubrication purposes. The materials comprise carbon nanotubes suspended in a liquid hydrocarbon carrier. Optionally, the compositions further comprise a surfactant (e.g., to aid in dispersion of the carbon particles). Specifically, the novel lubricants have the ability to significantly lower friction and wear, which translates into improved fuel economies and longer durability of mechanical devices and engines.

  • Patent number: 9314770
    Abstract: In one preferred embodiment, a photocatalyst for conversion of carbon dioxide and water to a hydrocarbon and oxygen comprises at least one nanoparticulate metal or metal oxide material that is substantially free of a carbon coating, prepared by heating a metal-containing precursor compound in a sealed reactor under a pressure autogenically generated by dissociation of the precursor material in the sealed reactor at a temperature of at least about 600° C. to form a nanoparticulate carbon-coated metal or metal oxide material, and subsequently substantially removing the carbon coating. The precursor material comprises a solid, solvent-free salt comprising a metal ion and at least one thermally decomposable carbon- and oxygen-containing counter-ion, and the metal of the salt is selected from the group consisting of Mn, Ti, Sn, V, Fe, Zn, Zr, Mo, Nb, W, Eu, La, Ce, In, and Si.

  • Patent number: 8648019
    Abstract: This invention relates to carbon-based materials as anti-friction and anti-wear additives for advanced lubrication purposes. The materials have various shapes, sizes, and structures and are synthesized by autogenic reactions under extreme conditions of high temperature and pressure. The lubricant compositions comprise carbon-based particles suspended in a liquid hydrocarbon carrier. Optionally, the compositions further comprise a surfactant (e.g., to aid in dispersion of the carbon particles). Specifically, the novel lubricants have the ability to significantly lower friction and wear, which translates into improved fuel economies and longer durability of mechanical devices and engines.

  • Patent number: 8580222
    Abstract: A single step process for degrading plastic waste by converting the plastic waste into carbonaceous products via thermal decomposition of the plastic waste by placing the plastic waste into a reactor, heating the plastic waste under an inert or air atmosphere until the temperature of about 700° C. is achieved, allowing the reactor to cool down, and recovering the resulting decomposition products therefrom. The decomposition products that this process yields are carbonaceous materials, and more specifically carbon nanotubes having a partially filled core (encapsulated) adjacent to one end of the nanotube. Additionally, in the presence of a transition metal compound, this thermal decomposition process produces multi-walled carbon nanotubes.

  • Patent number: 8568914
    Abstract: A lithium- or lithium-ion electrochemical cell of the present invention comprises a lithium-containing cathode, an anode, and a non-aqueous lithium-containing electrolyte therebetween; wherein one or more of the anode and the cathode comprises at least one particulate carbon-containing material selected from the group consisting of one or more carbon-coated metal oxide or metal phosphate particles, carbon-containing metals that alloy with Li, carbon-containing metalloids that alloy with Li, or rounded carbon particles such as carbon spheres, prolate-shaped spheroids, oblate-shaped spheroids, and carbon nanotubes. In a preferred embodiment, the particulate carbon material is prepared by reacting one or more solid, solvent-free chemical precursor materials comprising the elements making up the material in an enclosed autogenic pressure reactor in which the precursor materials are dissociated and reacted at elevated temperature, thereby creating self-generated pressure within the reactor.
