Patents by Inventor Petra Bitterli

Petra Bitterli has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Use and process for production of nanotubes
    Patent number: 6605266
    Abstract: Separable nanotubes are made from a transition metal oxide, preferably from a vanadium oxide of variable valence. They show a greater oxidation resistance than the carbon-based nanotubes known so far and offer many new and economic applications. The inventive nanotubes clearly show oxidation-reduction activities and are particularly suited as an active material for catalytic reactions.
    Type: Grant
    Filed: January 19, 2001
    Date of Patent: August 12, 2003
    Assignee: Eidg. Technische Hochschule Zurich
    Inventors: Reinhard Nesper, Michael Spahr, Markus Niederberger, Petra Bitterli
