Patents by Inventor Wendy L. Mao

Wendy L. Mao 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).

  • Patent number: 8066968
    Abstract: A novel molecular alloy of O2 and H2 and a method of producing such a molecular alloy are provided. When subjected to high pressure and extensive x-radiation, H2O molecules cleaved, forming O—O and H—H bonds. In the method of the present invention, the O and H framework in ice VII was converted into a molecular alloy of O2 and H2. X-ray diffraction, x-ray Raman scattering, and optical Raman spectroscopy demonstrate that this crystalline solid differs from previously known phases.
    Type: Grant
    Filed: October 24, 2008
    Date of Patent: November 29, 2011
    Assignee: Carnegie Institution of Washington
    Inventors: Ho-kwang Mao, Wendy L. Mao
  • Patent number: 7574868
    Abstract: The invention relates to a method of storing hydrogen that employs a mixture of hydrogen and a hydrocarbon that can both be used as fuel. In one embodiment, the method involves maintaining a mixture including hydrogen and a hydrocarbon in the solid state at ambient pressure and a temperature in excess of about 10 K.

  • Patent number: 6735960
    Abstract: A method for hydrogen storage includes providing water and hydrogen gas to a containment volume, reducing the temperature of the water and hydrogen gas to form a hydrogen clathrate at a first cryogenic temperature and a first pressure and maintaining the hydrogen clathrate at second cryogenic temperature within a temperature range of up to 250 K to effect hydrogen storage. The low-pressure hydrogen hydrate includes H2O molecules, H2 molecules and a unit cell including polyhedron cages of hydrogen-bonded frameworks of the H2O molecules built around the H2 molecules.
