  • METHOD AND APPARATUS FOR SYNTHESIZING FILAMENTARY STRUCTURES
    Publication number: 20120134910
    Abstract: Method and apparatus for producing filamentary structures. The structures include single-walled nanotubes. The method includes combusting hydrocarbon fuel and oxygen to establish a non-sooting flame and providing an unsupported catalyst to synthesize the filamentary structure in a post-flame region of the flame. Residence time is selected to favor filamentary structure growth.
    Type: Application
    Filed: February 1, 2008
    Publication date: May 31, 2012
    Applicant: MASSACHUSETTS INSTITUTE OF TECHNOLOGY
    Inventors: Murray J. Height, Jack B. Howard, John B. Vandersande

  • Preparation of superconducting oxides and oxide-metal composites
    Patent number: 5883052
    Abstract: A method of preparing a superconducting oxide by combining the matalic elements of the oxide to form an alloy, folled by oxidation of the alloy to form the oxide. Superconducting oxide-metal composites are prepared in which a noble metal phase intimately mixed with the oxide phase results in improved mechanical properties. The superconducting oxides and oxide-metal composites are provided in a variety of useful forms.
