  • Direct synthesis of long single-walled carbon nanotube strands
    Patent number: 7615204
    Abstract: Long, macroscopic nanotube strands or cables, up to several tens of centimeters in length, of aligned single-walled nanotubes are synthesized by the catalytic pyrolysis of n-hexane using an enhanced vertical floating catalyst CVD technique. The long strands of nanotubes assemble continuously from ropes or arrays of nanotubes, which are intrinsically long. These directly synthesized long nanotube strands or cables can be easily manipulated using macroscopic tools.
    Type: Grant
    Filed: February 24, 2003
    Date of Patent: November 10, 2009
    Assignees: Rensselaer Polytechnic Institute, Tsinghua University
    Inventors: Pulickel M. Ajayan, Bingqing Wei, Hongwei Zhu, Cailu Xu, Dehai Wu
  • Method of producing nanostructured metals using high-intensity ultrasonic vibration
    Publication number: 20070256764
    Abstract: A method of producing a nanostructured article includes simultaneously subjecting a body of material to external force and vibration to produce a desired nanostructure in the body of material.
