Srinivas Somayajula 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).

  • Filters and methods of making and using the same
    Patent number: 7341618
    Abstract: Filters for removing particulate and gaseous organic and inorganic materials from a fluid stream are disclosed. The filter may contain a polymer matrix and optional sequestering agents. Methods of making the filters are also disclosed. Methods of using the filters to remove one or more materials from a fluid stream, such as an air stream, are also disclosed.
    Type: Grant
    Filed: October 24, 2003
    Date of Patent: March 11, 2008
    Assignee: Georgia Tech Research Corporation
    Inventors: Charlene W. Bayer, Amy L. Cook, Mark Rule, Victor R. DeJesus, Robert J. Hendry, Daniel P. Campbell, Srinivas Somayajula, Thomas R. Mohs
  • Methods for treating membranes and separation facilities and membrane treatment composition
    Patent number: 7220358
    Abstract: A method for treating a separation facility is provided according to the invention. The separation facility includes a plurality of membranes for providing separation of a feed product. The method includes steps of providing liquid flow through a plurality of membranes; treating the plurality of membranes with a multiple phase treatment composition comprising a gaseous phase and a liquid phase at a volumetric ratio of the gaseous phase to the liquid phase of at least about 5:1; and providing a liquid flow through the plurality of membranes.

  • Methods of measuring the diffusion rate and partition coefficient of an analyte into a polymer and methods of forming a filter media
    Patent number: 7025800
    Abstract: A method of determining the diffusion rate of a given analyte into a polymer film using an optical waveguide interferometer is disclosed. A method of forming a filter media by selecting a polymer for the sorbent system of the filter media based on the diffusion rate of a given analyte into a given polymer as measured by an optical waveguide interferometer is further disclosed.
