Patents by Inventor Mayumi Kiyono

Mayumi Kiyono 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).

  • Chromatographic separation material
    Patent number: 9302203
    Abstract: The chromatographic separation material is a cyclofructan or a derivative of cyclofructan covalently bonded to a cross-linked, organic polymer. The separation material works well in hydrophilic interaction liquid chromatography.
    Type: Grant
    Filed: July 27, 2012
    Date of Patent: April 5, 2016
    Assignees: MITSUBISHI CHEMICAL CORPORATION, AZYP, LLC
    Inventors: Haixiao Qiu, Daniel W. Armstrong, Mayumi Kiyono-Shimobe
  • Method for producing carbon molecular sieve membranes in controlled atmospheres
    Patent number: 8709133
    Abstract: The invention concerns carbon molecular sieve membranes (“CMS membranes”), and more particularly the use of such membranes in gas separation. In particular, the present disclosure concerns an advantageous method for producing CMS membranes with desired selectivity and permeability properties. By controlling and selecting the oxygen concentration in the pyrolysis atmosphere used to produce CMS membranes, membrane selectivity and permeability can be adjusted. Additionally, oxygen concentration can be used in conjunction with pyrolysis temperature to further produce tuned or optimized CMS membranes.
    Type: Grant
