Junhui He 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).

  • Metal nanoparticle with support, continuous metal nanoparticle body, and methods for producing these
    Patent number: 7708800
    Abstract: There is disclosed a method for producing a supported metal nanoparticle, which has the steps of adsorbing a metal ion-containing compound to a support of an organic material and reducing the adsorbed metal ion to form a metal nanoparticle on the support. In the producing method, by using a various organic material as a matrix, the metal nanoparticle can be easily formed in situ with excellent accuracy from the metal ion-containing compound.
    Type: Grant
    Filed: May 28, 2004
    Date of Patent: May 4, 2010
    Assignee: Riken
    Inventors: Junhui He, Toyoki Kunitake
  • Nanomaterials of composite metal oxides
    Patent number: 7704549
    Abstract: Exchangeable metal ions are removed from an amorphous composite metal oxide and different metal ions are introduced to manufacture a nanomaterial of composite metal oxide. Based on this method, it is possible to reliably form composite metal oxide nanomaterials over a wide range of compositions.
