Pelagia-Irene Gouma 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).

  • Free-standing fluid sensors, filters, and catalyst devices, and methods involving same
    Patent number: 6689322
    Abstract: The present invention includes free-standing, shaped ceramic-bearing bodies useful in fluid sensors, filters, and catalyst devices. The invention also includes methods and processes for using such devices. In a preferred embodiment of the invention, shaped metallic foils are converted into free-standing, porous rutile foils having an open pore structure by oxidation at an elevated temperature. The exposure of such foils to increasing concentrations of reducing gases such as carbon monoxide results in an increase in the steady-state electrical resistance. The resultant ceramic-bearing bodies may be used as effective sensors of reducing gas species in such applications as automobile and industrial emissions.
    Type: Grant
    Filed: March 29, 2000
    Date of Patent: February 10, 2004
    Assignee: The Ohio State University
    Inventors: Michael John Mills, Kenneth Henry Sandhage, Pelagia-Irene Gouma

  • Sensors including metal oxides selective for specific gases and methods for preparing same
    Publication number: 20030217586
    Abstract: Sensors are provided which are selective for a specific gas. The sensors include a substrate, electrodes, and a thin film metal oxide. Methods for choosing the metal oxide to be utilized in the sensor with selectivity for the specific gas are also provided, as are methods for determining the presence of a specific gas in a gaseous mixture.
