  • Fast ignition and sustained combustion of ionic liquids
    Patent number: 9388090
    Abstract: A catalyst free method of igniting an ionic liquid is provided. The method can include mixing a liquid hypergol with a HAN-based ionic liquid to ignite the HAN-based ionic liquid in the absence of a catalyst. The HAN-based ionic liquid and the liquid hypergol can be injected into a combustion chamber. The HAN-based ionic liquid and the liquid hypergol can impinge upon a stagnation plate positioned at top portion of the combustion chamber.

  • Recovery of rare earth elements and compounds from coal ash
    Patent number: 8968688
    Abstract: Rare earth elements are recovered from coal ash. The coal ash with rare earth elements can be treated with a mineral acid to form an aqueous mineral acid solution. The aqueous mineral acid solution can be extracted to form an organic solution that includes the rare earth salts. The organic solution can be mixed with water to form an aqueous solution that includes the rare earth salts. The rare earth elements are separated from the aqueous solution.

  • Forming spherical crystal habit
    Patent number: 8962888
    Abstract: Methods for forming spherical crystal habit are shown. A needle-shaped crystal habit, a solvent, and a surfactant are combined and dissolved forming a first solution. The first solution and an anti-solvent are combined forming a second solution. The second solution is cooled. Spherical crystal habit is formed.
