| 20100234204 | ORGANOSILICON NANOSILICON COMPOSITES AND FABRICATION METHODS - Embodiments of the invention provide organosilicon silicon 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 organosilicon silicon nanoparticle composites. A preferred method for forming an organosilicon 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 organosilicon nanoparticle composite. | 09-16-2010 |
| 20100129300 | ORGANOSILICON COMPOUNDS, FATTY ACIDS AND OILS WITH HOMOGENOUS SILICON NANOPARTICLE DISPERSIONS - The invention provides homogenous dispersions of luminescent silicon nanoparticles in organoslicoon compounds, fatty acids and oils. In methods of the invention, a fatty acid or oil and silicon nanoparticle homogenous dispersion is formed by mixing. The dispersion of nanoparticles in organosilicon compounds, fatty acid(s) or oil(s) can used as a delivery mechanism to homogenously incorporate the nanoparticles into a variety of cosmetic compounds and oils, such as foundation creams and other make-up products, sun tan lotions, sun tan oils, etc. Compounds of the invention with homogenous nanoparticle dispersions display homogeneous UV/blue absorption as well as down conversion to visible luminescence. The compounds can be tailored to exhibit white luminescence under UV illumination. Preferred skin care compounds provide a pleasing cosmetic effect in response to light. Preferred skin care compounds also provide uv protection. | 05-27-2010 |
