  • Patent number: 8530617
    Abstract: A process for producing silicon-containing particles having an extremely small particle diameter by a simple process without using surface-active agents or the like. The process is characterized by forming silicon-containing particles as a result of phase separation from an organic polymer, wherein the phase separation is achieved by an addition reaction, condensation reaction, ring-opening reaction, or a radical reaction of a curable silicon-containing compound or a curable composition that contains said compound, and the silicon-containing compound or the composition is maintained in a uniform liquid, fused, or dissolved phase with the organic polymer that is free of silicon and does not participate in the curing reaction of the silicon-containing compound or the composition.

  • Patent number: 8389627
    Abstract: The present invention provides novel filled silicone compositions comprising a nano-particulate metal oxide filler selected from nano-particulate monoclinic alpha-phase bismuth oxide, nano-particulate erbium oxide, and mixtures thereof. The new composite compositions exhibit a combination of outstanding performance characteristics in both the cured and uncured states. Thus, the uncured formulations are typically free flowing liquids which are self-leveling, which de-gas readily under vacuum, are readily colorable through the addition of pigments, and which cure at temperatures of about 60° C. The cured compositions possess outstanding acoustic characteristics which make them ideally suited for use in applications such as acoustic lenses for medical imaging and therapy. For example, the acoustic impedance of compositions provided by the present invention is closely matched to the acoustic impedance of human tissue.

  • Patent number: 8367769
    Abstract: Embodiments of the invention provide silicon-based nanoparticle composites, where the silicon nanoparticles are highly luminescent. Preferred embodiments of the invention are Si—O solid composite networks, e.g., glass, having a homogenous distribution of luminescent hydrogen terminated silicon nanoparticles in a homogenous distribution throughout the solid. Embodiments of the invention also provide fabrication processes for silicon-based silicon nanoparticle composites. A preferred method for forming a silicon-based nanoparticle composite disperses hydrogen terminated silicon nanoparticles and an inorganic precursor of an organosilicon gel in an aprotic solvent to form a sol. A catalyst is mixed into the sol. The sol is then permitted to dry into a gel of the silicon-based nanoparticle composite.
