  • Hydrogen isotope exchange methods and systems for organic and organosilicon materials
    Patent number: 11981613
    Abstract: Disclosed are methods and systems for hydrogen isotope exchange of organic molecules that can be carried out with no alteration in the chemical structure of the organic molecules. Methods can be utilized to incorporate a particular hydrogen isotope on an organic molecule (e.g., deuteration or tritiation) or to remove a particular hydrogen isotope from an organic molecule (e.g., detritiation).
    Type: Grant
    Filed: January 20, 2023
    Date of Patent: May 14, 2024
    Assignee: Battelle Savannah River Alliance, LLC
    Inventors: George K. Larsen, III, Tyler C. Guin, Joseph E. Meany, Jay B. Gaillard, Mark C. Elvington

  • Synthesis of nanosized sodium titanates
    Patent number: 9145304
    Abstract: Methods directed to the synthesis and peroxide-modification of nanosized monosodium titanate are described. Methods include combination of reactants at a low concentration to a solution including a nonionic surfactant. The nanosized monosodium titanate can exhibit high selectivity for sorbing various metallic ions.

  • FORMATION OF NANOSIZED METAL PARTICLES ON A TITANATE CARRIER
    Publication number: 20150071980
    Abstract: Methods directed to the synthesis of metal nanoparticles are described. A formation process can be carried out at ambient temperature and pressure and includes the deposition of metal ions on a titanate carrier according to a chemical deposition process followed by exposure of the metal ions to a reducing agent. Upon the exposure, nanoparticles of the reduced metal are formed that are adhered to the titanate carrier.
