Patents by Inventor Yali Su

Yali Su 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).

  • Structure having spatially separated photo-excitable electron-hole pairs and method of manufacturing same
    Patent number: 7094675
    Abstract: A method for producing quantum dots. The method includes cleaning an oxide substrate and separately cleaning a metal source. The substrate is then heated and exposed to the source in an oxygen environment. This causes metal oxide quantum dots to form on the surface of the substrate.
    Type: Grant
    Filed: January 10, 2003
    Date of Patent: August 22, 2006
    Assignee: Battelle Memorial Institute
    Inventors: Yong Liang, John L. Daschbach, Yali Su, Scott A. Chambers
  • Nanocrystalline heterojunction materials
    Patent number: 6685909
    Abstract: Mesoporous nanocrystalline titanium dioxide heterojunction materials and methods of making the same are disclosed. In one disclosed embodiment, materials comprising a core of titanium dioxide and a shell of a molybdenum oxide exhibit a decrease in their photoadsorption energy as the size of the titanium dioxide core decreases.
    Type: Grant
