Xiqu Wang 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).

  • Porous solids, selective separations, removal of sulfur compounds, adsorption
    Patent number: 8974675
    Abstract: Crystals of [VOBDC](H2BDC)0.71 were synthesized hydrothemally. The guest acid molecules were removed by heating in air to give high quality single crystals of VOBDC. VOBDC was observed to show crystal-to-crystal transformations on absorption of the guest molecules aniline, thiophene and acetone from the liquid phase. Accurate structural data of the guest molecules and framework deformations were obtained from single crystal X-ray data. VOBDC was also shown to absorb selectively thiophene and dimethyl sulphide from methane.
    Type: Grant
    Filed: October 22, 2012
    Date of Patent: March 10, 2015
    Inventors: Allan J. Jacobson, Xiqu Wang, Lumei Liu

  • Microporous crystalline metal silicates and processes for their preparation
    Patent number: 7314605
    Abstract: New bridged layered silicates are disclosed where the bridging groups bridge adjacent silicate layers via oxygen atoms on each silicate layer that are unshared to produce porous three dimensional structures. Methods for making these bridged layered silicates are disclosed as well as methods for using these compositions as catalysts, supports, adsorbents, drying agents and ion exchangers.
