  • Controlled synthesis of nanoparticles using ultrasound in continuous flow
    Patent number: 9073761
    Abstract: Apparatuses and methods for synthesizing nanoparticles are provided. Methods for synthesizing nanoparticles are provided comprising mixing at least two solutions comprising the components of the nanoparticles within a micromixer; exposing the resultant mixed, unreacted, azeotropic solution to ultrasound; and collecting the generated nanoparticles. Apparatuses are also provided for synthesizing nanoparticles comprising a micromixer in fluid connection with a continuous reactor comprising at least one inlet, at least one outlet, and an ultrasound horn oriented such that the acoustic energy is transferred to the fluid within the continuous reactor.

  • Rhenium recovery from superalloys and associated methods
    Patent number: 8038764
    Abstract: A method of recovering rhenium from rhenium-containing superalloy scrap is provided. The superalloy is usually a nickel-based superalloy. The method includes the steps of forming an oxidation feedstock of flaky morphology of the superalloy scrap, and oxidizing the oxidation feedstock to convert rhenium into a volatile rhenium oxide. The flaky morphology of the oxidation feedstock is achieved by increasing the surface area of the superalloy scrap.
