  • Functional graphene-polymer nanocomposites for gas barrier applications
    Patent number: 8110026
    Abstract: A gas diffusion barrier contains a polymer matrix and a functional graphene which displays no signature of graphite and/or graphite oxide, as determined by X-ray diffraction.
    Type: Grant
    Filed: October 6, 2006
    Date of Patent: February 7, 2012
    Assignee: The Trustees of Princeton University
    Inventors: Robert Prud'Homme, Christopher O'Neil, Bulent Ozbas, Ilhan Aksay, Richard Register, Douglas Adamson
  • NOVEL HYDROGELS AND USES THEREOF
    Publication number: 20110052692
    Abstract: The present invention provides novel hydrogels and methods of making and using such hydrogels. The present invention provides hydrogels that may be formed by the self-assembly of peptides in solution. Such self-assembly may be brought about by a change in one or more characteristics of the solution. Characteristics of the solution that may be changed include pH, ionic strength, temperature, and concentration of one or more specific ions. In addition, hydrogels of the invention may be disassembled by changing one or more characteristic of the hydrogel such as pH, ionic strength, temperature, and concentration of one or more specific ions.
    Type: Application
