  • Apparatus and methods for synthesis of large size batches of carbon nanostructures
    Patent number: 8017892
    Abstract: An apparatus and method for synthesizing nanostructures. In one embodiment, the apparatus includes a reactor having a reaction zone and a conductive susceptor positioned in the reaction zone. The method includes the steps of transporting a gas mixture having an aerosolized catalyst, a feedstock and a carrier gas into the reaction zone of the reactor, inductively heating the reaction zone, and regulating a flow rate of the gas mixture to allow the catalyst to spend a sufficient amount of time in the reaction zone for the growth of nanostructures.
    Type: Grant
    Filed: July 10, 2008
    Date of Patent: September 13, 2011
    Assignee: Board of Turstees of the University of Arkansas
    Inventors: Alexandru Sorin Biris, Alexandru Radu Biris, Dan Lupu, Jon Gardner Wilkes, Dan Alexander Buzatu, Dwight Wayne Miller, Jerry A. Darsey

  • Production of nanostructure by curie point induction heating
    Publication number: 20080264330
    Abstract: An apparatus for synthesizing nanostructures. In one embodiment, the apparatus includes a heating device that defines a reaction zone therein and a susceptor made of a ferromagnetic material with a Curie temperature and placed in the reaction zone, where the Curie temperature substantially corresponds to a temperature at which the growth of desired nanostructures occurs and the heating device is capable of heating the susceptor substantially at the Curie temperature.
