Patents by Inventor Alpana Ranade

Alpana Ranade 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).

  • Composites including silicon-oxy-carbide layers and methods of making the same
    Patent number: 10787591
    Abstract: Composites comprising at least one silicon-oxy-carbide (SOC) layer deposited onto a polymeric matrix substrate to enhance their thermo-oxidative stability are provided. The SOC layer is formed onto the polymeric matrix substrate by atmospheric plasma deposition to produce an thermo-oxidative barrier coating or an adhesion-promoting layer to enable the deposition of a variety of known (or future developed) metallic and/or ceramic materials as oxygen and/or thermal barriers.
    Type: Grant
    Filed: March 15, 2013
    Date of Patent: September 29, 2020
    Assignee: THE BOEING COMPANY
    Inventors: Thomas K. Tsotsis, Marvi A. Matos, Alpana Ranade, Laura M. Murphy

  • INFRARED-REFLECTING FILMS AND METHOD FOR MAKING THE SAME
    Publication number: 20100092747
    Abstract: There is provided single layer infrared-reflecting films and a method of making the same that provide enhanced reflectivity in an 800 nanometer to 2500 nanometer infrared waveband. The method comprises providing a substrate, depositing onto the substrate a mixture of an oxide matrix material and either a conductive metal dopant or a higher valence cation, and producing the infrared-reflecting film.
