  • Patent number: 8859000
    Abstract: The present invention is directed to a process for synthesizing nanoparticles. This process involves providing a stable emulsion containing a plurality of droplets suspended in a continuous phase. The droplets, which are encapsulated by an interfacially-active material, contain a first reactant dissolved in a dispersed phase. The process also involves contacting a gas phase containing a second reactant diluted in a carrier gas with the stable emulsion under conditions effective to permit the first reactant and second reactant to react and form nanoparticles. The present invention further relates to nanoparticle-loaded emulsions and their uses in formulations for various purposes.

  • Patent number: 7008797
    Abstract: The present invention describes a method for recovery of aqueous samples or components thereof from polymer packaging materials, wherein the spilled aqueous sample has been absorbed by the packaging material to form a liquid swollen absorbent gel. The method comprises the steps of contacting the liquid swollen absorbent gel with a recovery fluid, wherein the recovery fluid has a higher osmotic pressure than the aqueous sample.

  • Patent number: 6503955
    Abstract: The present invention covers pourable liquid vehicles that can be combined with compositions, materials and substances. Among the benefits of such pourable liquid vehicles is the compositions are retained on the moistened surface for a period of time sufficient to allow compositions, materials and substances to act on said surface, resisting erosion or run-off from additional moisture being applied. Such pourable liquid vehicles have a number of utilities including but not limited to cleaning and treating surfaces of objects as well as biological or living organisms, including living creatures.
