Alexandra H. Brozena 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).

  • Covalently functionalized carbon nanostructures and methods for their separation
    Patent number: 8980216
    Abstract: The present invention is directed to carbon nanostructures, e.g., carbon nanotubes, methods of covalently functionalizing carbon nanostructures, and methods of separating and isolating covalently functionalized carbon. In some embodiments, carbon nanotubes are reacted with alkylating agents to provide water soluble covalently functionalized carbon nanotubes. In other embodiments, carbon nanotubes are reacted with a thermally-responsive agent and exposed to light in order to separate carbon nanotubes of a specific chirality from a mixture of carbon nanotubes.
    Type: Grant
    Filed: April 4, 2012
    Date of Patent: March 17, 2015
    Assignee: University of Maryland, College Park
    Inventors: YuHuang Wang, Alexandra H. Brozena, Shunliu Deng, Yin Zhang
