Katia Allegraud 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).

  • Surface Plasma Gas Processing
    Publication number: 20120315194
    Abstract: The invention relates to a gas processing unit adapted for generating a surface plasma in the vicinity of a photocatalyst, that has a planar configuration. The photocatalyst is deposited in the form of a thin layer on a dielectric substrate and at least one plasma supply electrode is formed above the photocatalyst thin layer. Such a configuration increases the interaction between the plasma and the photocatalyst. The unit can be used for a gas processing of the pollution-control, odour reduction or bactericidal treatment type with a high efficiency.
    Type: Application
    Filed: January 6, 2010
    Publication date: December 13, 2012
    Applicants: Centre National De La Recherche Scientifique-CRNS-, Ecole Polytechnique
    Inventors: Antoine Rousseau, Katia Allegraud, Olivier Guaitella
