    摘要： The present invention relates to a novel process for preparing sol-gel microcapsules loaded with up to 95% (w/w) functional molecules or substances and to the products obtained by said process. Said process is conducted in two steps: (a) creating an oil-in-water emulsion by emulsification of a water insoluble solution comprising the sol-gel precursors and the molecules to be loaded, in an aqueous solution under appropriate shear forces; (b) mixing and stirring said emulsion with an aqueous solution at a suitably selected pH to obtain loaded sol-gel microcapsules in suspension. The microcapsules so obtained can further be subjected to cycles of isolation and rinsing. Incorporation of the final product, either in the form of a suspension or a powder, in cosmetic formulations affords a transparent cream when applying to skin and has a smooth and pleasant contact.

    摘要： A method using computer software for automatic audio visual dubbing (5) using an efficient computerized automatic method for audio visual dubbing of movies by computerized image copying of the characteristic features of the lip movements of the dubber onto the mouth area of the original speaker. The invention uses a method of vicinity-searching, three-dimensional head modeling of the original speaker (3), and texture mapping (10) technique to produce new images which correspond to the dubbed sound track: The invention thus overcomes the well known disadvantage of the correlation problems between lip movement in an original movie and the sound track of the dubbed movie.

    摘要： The present invention relates to a method for obtaining improved photostability of a sunscreen composition that contains at least two sunscreen active ingredients, which are photo-unstable when formulated together, by microencapsulating at least one of said active ingredients in an encapsulating material suitable for holding the encapsulated active ingredient material, thus reducing or preventing its leaching out of the capsules; and adding other acceptable components and additives needed for the preparation of said composition. The sunscreen active ingredients can be selected from UVA and UVB absorbers, preferably a combination thereof. In a preferred embodiment of the present invention said active ingredients are encapsulated in separate sol-gel microcapsules.

    摘要： Chromatography processes employ doped sol gel glasses as chromatographic media. In one embodiment, a process for qualitative or quantitative determination of a reactive chemical contained in a sample comprises passing the sample through a column or planar chromatography apparatus wherein the apparatus includes packing or plates containing a porous doped sol gel glass. The doped sol gel glass is formed form a metal alkoxide and contains a compound encapsulated therein which is reactive with the reactive chemical in the pores of the doped sol gel glass. In another embodiment, a process for analyzing a gas sample containing a reactive chemical comprises passing the gas sample through glass capillaries or tubes containing porous doped sol gel glass pellets. The pellets are formed from a metal alkoxide and contain a colorimetric reagent encapsulated therein which is reactive with the reactive chemical in the pores of the pellets. In a third embodiment, a doped sol gel glass is included in the chromatographic media for pretreatment cleanup for interference removal prior to the chromatographic separation.
