  • Hydroxyethylhydrazinium nitrate-acetone formulations and methods of making hydroxyethylhydrazinium nitrate-acetone formulations
    Patent number: 9481840
    Abstract: Embodiments of the present disclosure include one-step synthesis to prepare a hypergolic green Fuel (HGF) propellant from 2-Hydroxyethylhydrazine (HEH) via a “one-step synthesis method”. In addition, embodiments of the present disclosure include fully nitrated HGF and partially nitrated HGF and formulations containing Hydroxyethylhydrazinium Nitrate (HEHN) and acetone, where the HEHN is produced independently.
    Type: Grant
    Filed: April 9, 2010
    Date of Patent: November 1, 2016
    Assignees: UNIVERSITY OF ALABAMA IN HUNTSVILLE, OGDEN ENGINEERING & ASSOCIATES, LLC
    Inventors: James E. Smith, Jr., Gregory E. Ogden, Clinton J. Brown, Paul M. Frisby, Sahar A. Torabzadeh
  • Graphite thermal decontamination with reducing gases
    Patent number: 9040014
    Abstract: Providing a roaster that operates at temperatures in the range of 800° Celsius to 2000° Celsius with inert, optional oxidizing and reducing gases to treat graphite contaminated with radionuclides including tritium, carbon-14, and chlorine-36. The combination of temperatures and gases allow for the removal of most to substantially all the carbon-14 within the graphite while substantially limiting gasifying the bulk graphite.
