Patents by Inventor Atsuski Nakahira

Atsuski Nakahira 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).

  • Nanocrystalline apatites and composites, prostheses incorporating them, and method for their production
    Patent number: RE43661
    Abstract: Methods for synthesis of nanocrystalline apatites are presented, as well as a series of specific reaction parameters that can be adjusted to tailor, in specific ways, properties in the recovered product. Particulate apatite compositions having average crystal size of less than 150 nm are provided. Products also can have a surface area of at least 40 m2/g and can be of high density. Hydroxy apatite material is investigated in particular detail. Compositions of the invention can be used as prosthetic implants and coatings for prosthetic implants.
    Type: Grant
    Filed: March 29, 2010
    Date of Patent: September 18, 2012
    Assignee: Massachusetts Institute of Technology
    Inventors: Jackie Y. Ying, Edward S. Ahn, Atsuski Nakahira
