  • Publication number: 20120322645
    Abstract: Nanocomposites of multi-phase metal oxide ceramics have been produced from water soluble salts of the resulting metal oxides by a foaming esterification sol-gel method. The evolution of volatile gases at elevated temperature during the esterification reaction causes the formation of a foam product. Nanocomposites of multi-phase metal oxide ceramics have also been produced by a cation polymer precursor method. In this second method, the metal cations are chelated by the polymer and the resulting product is gelled and foamed. Calcination of the resulting foams gives nanocomposite powders with extremely fine, uniform grains and phase domains. These microstructures are remarkably stable both under post-calcination heat treatment and during consolidation by hot-pressing.

  • Publication number: 20120211909
    Abstract: Sulfur seeds may be produced by spraying liquid molten sulfur from a sulfur spray nozzle into a moving stream of liquid. Some of the sulfur may pass through the liquid and some of the sulfur may be entrained in and transported by the stream of liquid, or all of the sulfur may be entrained in the stream of liquid. The sulfur droplets that are entrained in the stream of liquid may be carried by the liquid to a cooling tank, which may be a spiral dewaterer tank with an angled bottom and a screw conveyor. An opening may be made in the bottom surface of the screw conveyor housing of the spiral dewaterer tank for liquid to drain from the screw conveyor as it moves sulfur seeds from the tank to a the drum. A screen may be disposed across the opening, and a drain trough attached to the screw conveyor housing to capture any liquid and solids that move through the screen. A wash line may assist in moving solids that pass through the screen.

  • Publication number: 20120187591
    Abstract: The present invention provides for methods of preparing silk nanoparticles and microparticles, methods of encapsulating an active agent into the silk nano- and microparticles and compositions comprising these silk particles. In particular, the silk spheres are prepared from phase separation of silk and polyvinyl alcohol (PVA), without exposure to an organic solvent. The method employs a chemical, PVA, which is an FDA-approved ingredient in drug formulations. Different parameters can be adjusted to control the size and shape of the silk spheres during the fabrication process. The silk particle compositions of the present invention may also encapsulate active agents or chemicals. Such compositions allow the active agents to be controllably and sustainably released to the target organs or tissues. The silk composition entrapping active agents also provides for a long-term storage medium for the active agents so entrapped.
