Ulvi F. Ilhan 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).

  • Highly porous and mechanically strong ceramic oxide aerogels
    Patent number: 8227363
    Abstract: Structurally stable and mechanically strong ceramic oxide aerogels are provided. The aerogels are cross-linked via organic polymer chains that are attached to and extend from surface-bound functional groups provided or present over the internal surfaces of a mesoporous ceramic oxide particle network via appropriate chemical reactions. The functional groups can be hydroxyl groups, which are native to ceramic oxides, or they can be non-hydroxyl functional groups that can be decorated over the internal surfaces of the ceramic oxide network. Methods of preparing such mechanically strong ceramic oxide aerogels also are provided.
    Type: Grant
    Filed: February 8, 2010
    Date of Patent: July 24, 2012
    Assignees: Ohio Aerospace Institute, The United States of America as represented by the Administrator of National Aeronautics and Space Administration
    Inventors: Nicholas Leventis, Mary Ann B. Meador, James C. Johnston, Eve F. Fabrizio, Ulvi F. Ilhan
