  • Synthetic layered silicate nanolayers
    Patent number: 7714156
    Abstract: Nanolayered layered silicate materials of octahedrally arranged units with divalent metal ions at centers of the units covalently linked above and below to tetrahedrally arranged oxygen and hydroxyl units with silicon atoms. The silicate materials contain silanol groups which are reactive to form derivative compositions useful for water purification to remove heavy meal cations.
    Type: Grant
    Filed: August 12, 2008
    Date of Patent: May 11, 2010
    Assignee: Board of Trustees of Michigan State University
    Inventors: Thomas J. Pinnavaia, Mihai Polverejan
