  • Publication number: 20200262705
    Abstract: Processes for altering the structure and/or properties of carbon nanomaterials and inorganic nanomaterials, such as boron nitride nanotubes are described. The processes can be used to produce a carbon nanotube product comprising predominantly carbon nanotube (CNTs) having a desired average length. The processes can also be used to fabricate carbon nanodots. The processes can also be used to slice inorganic nanotubes or nanowires. The processes can also be used to form supramolecular fullerene assemblies.

  • Patent number: 10629933
    Abstract: A process for producing hydrogen from a hydrocarbon gas comprising contacting at elevated temperature the hydrocarbon gas with a catalyst to catalytically convert the hydrocarbon gas to hydrogen and solid carbon; wherein, the catalyst comprises one or both of the following: (a) a calcined Fe-containing catalyst; or (b) a bimetallic MxNiy-type catalyst supported on a substrate.
    Type: Grant

  • Patent number: 8365923
    Abstract: A method of separating at least one carbon nanotube having a desired diameter and/or chirality from a mixture of carbon nanotubes having different diameters and/or chiralities is provided. A calixarene of formula (I): wherein n?4; X is PO3H2, Ra—PO3H, SO3H, or Ra—SO3H; Y is Rb, OH, or ORb; and Ra and Rb are independently selected from the group consisting of optionally substituted alkyl, optionally substituted aryl, optionally substituted arylene alkyl and optionally substituted alkylene aryl is combined with the mixture of carbon nanotubes in an aqueous solvent to produce an aqueous supernatant containing the carbon nanotube(s) having the desired diameter and/or chirality. The aqueous supernatant containing the carbon nanotube(s) is then separated from a residue comprising the remaining carbon nanotubes of the mixture.

  • Publication number: 20030134035
    Abstract: A method of applying a hydrophobic film to a surface, the method comprising the steps of (a) optionally modifying particles to be coated on the surface so as to form functional groups thereon: (b) applying particles having functional groups thereon to the surface to be coated: and (c) treating the applied particles such that the particles arc bound together and to the surface by chemical cross-linking of the functional groups on the particles. The method may further include the addition of a non-silicone polymer to the particles prior to step (b) to assist in the formation of the film.
