  • Patent number: 8803025
    Abstract: A plasma gun system comprising: a plasma gun comprising an outlet, wherein the plasma gun is configured to generate a plasma stream and provide the plasma stream to the outlet; and a plasma gun extension assembly configured to be coupled to the plasma gun, wherein the plasma gun extension assembly comprises an extension chamber and a port, the extension chamber having an interior diameter defined by a chamber wall and being configured to receive the plasma stream from the outlet of the plasma gun and to enable the plasma stream to expand upon entering the extension chamber, and the port being configured to introduce a powder to the expanded plasma stream at a location outside of the plasma gun.

  • Publication number: 20110143930
    Abstract: A method of tuning the size of an nano-active material on a nano-carrier material comprising: providing a starting portion of a carrier material and a starting portion of an active material in a first ratio; adjusting the first ratio, forming a second ratio, thereby tuning the ratio of active material and carrier material; combining the portion of the active material in a vapor phase and the portion of the carrier material in a vapor phase, forming a conglomerate in a vapor phase; and changing the phase of the conglomerate, thereby forming nano-spheres comprising a nano-carrier material decorated with a nano-active material, wherein the size of the nano-active material is dependent upon the second ratio.

  • Publication number: 20110143916
    Abstract: A method of producing a catalyst comprising: mixing catalytic particles and a solvent, thereby forming a mixture; performing a size distribution analysis on the mixture to determine a size distribution profile; repeating the mixing of the catalytic particles and the solvent in the mixture if the size distribution profile is below a threshold; centrifuging the mixture if the size distribution profile is at or above the threshold, thereby forming a supernate and a precipitate, wherein the supernate comprises a dispersion including the catalytic particles and the solvent; decanting the mixture, separating the supernate from the precipitate; determining the particle content of the separated supernate; determining a volume of the dispersion to be applied to a catalyst support based on one or more properties of the catalyst support; and impregnating the catalyst support with the catalytic particles in the dispersion by applying the volume of the dispersion to the catalyst support.
