  • Production of metal nanoparticles
    Patent number: 7749299
    Abstract: A process for the production of metal nanoparticles. The process comprises a rapid mixing of a solution of at least about 0.1 mole of a metal compound that is capable of being reduced to a metal by a polyol with a heated solution of a polyol and a substance that is capable of being adsorbed on the nanoparticles.
    Type: Grant

    Assignee: Cabot Corporation
    Inventors: Karel Vanheusden, Klaus Kunze, Hyungrak Kiim, Aaron D. Stump, Allen B. Schult, Mark J. Hampden-Smith, Chuck Edwards, Anthony R. James, James Caruso, Toivo T. Kodas, Scott Thomas Haubrich, Mark H. Kowalski
  • Separation of metal nanoparticles
    Patent number: 7575621
    Abstract: A process for the production of metal nanoparticles. Nanoparticles are formed by combining a metal compound with a solution that comprises a polyol and a substance that is capable of being adsorbed on the nanoparticles. The nanoparticles are precipitated by adding a nanoparticle-precipitating liquid in a sufficient amount to precipitate at least a substantial portion of the nanoparticles and of a protic solvent in a sufficient amount to improve the separation of the nanoparticles from the liquid phase.
