摘要:A method for producing zeolite films or membranes at essentially ambient pressure, which includes preparing a synthesis mixture comprising an ionic liquid solvent and an aluminum and/or silicon and/or phosphate source and converting the synthesis mixture to form a continuous zeolite layer. In addition, a method of synthesizing zeolite nanocrystals, which includes preparing a synthesis mixture, the synthesis mixture having a silica or a silica and alumina source, and a template; and synthesizing the synthesis mixture to form zeolite nanocrystals.

摘要:The invention discloses and claims a new class of chemical compositions with ideal sunscreen properties. The chemical composition comprises spherical particles between 200 nm and 10 microns in diameter prepared by an emulsion polymerization of tetraalkoxysilanes or organotrialkoxysilanes or organobridged trialkoxysilanes with a dye monomer bearing two or more alkoxysilyl groups attached to the bridging chromophore. The resulting spheres absorb ultraviolet light. The dye can be any organic chromophore capable of receiving multiple trialkoxysilyl groups resulting in multipoint covalent attachment that precludes leaching of the dye from the spheres. The formic acid-toluene-monomer emulsion polymerization allows for large-scale (>100 gram) synthesis of monodisperse particles under acidic, non-aqueous conditions without surfactants. The particles less than 1 micron in diameter are smooth as talc to the touch and will provide a smooth formulation for sunscreen creams or lotions.
