  • Molecular nanowires from single walled carbon nanotubes
    Patent number: 7112315
    Abstract: Unique single walled nanotube compositions and methods for making the composition wherein the nanotubes encloses foreign material capable of forming thread-like material having a solid form at ambient temperatures and pressures.
    Type: Grant
    Filed: July 15, 1999
    Date of Patent: September 26, 2006
    Assignee: The Regents of the University of California

  • Rapid synthesis of carbon nanotubes and carbon encapsulated metal nanoparticles by a displacement reaction
    Patent number: 6479028
    Abstract: Carbon material having at least a partially curved structure, such as a nanotube, produced by a displacement reaction in which a carbon halide, e.g. C2Cl6, is reacted with a metal compound, e.g., lithium acetylide in the presence of a catalyst, e.g., CoCl2. Some applications of the nanotubes of the present invention are use in magnetic data storage media, or use as conductors or semiconductors.
