摘要:
The present subject matter relates generally to design, synthesis, and characterization of materials with well-defined porous networks of molecular dimensions in which the size and surface energy of the pores can be externally and reversibly controlled to dynamically modulate the adsorption and transport of molecular species.

摘要:
The present invention provides for evaporation induced self-assembly (EISA) within microdroplets produced by a vibrating orifice aerosol generator (VOAG) for the production of monodisperse mesoporous silica particles. The process of the present invention exploits the concentration of evaporating droplets to induce the organization of various amphiphilic molecules, effectively partitioning a silica precursor to the hydrophilic regions of the structure. Promotion of silica condensation, followed by removal of the surfactant, provides ordered spherical mesoporous particles.

摘要:
A process is described for manufacturing a titanium dioxide pigment, comprising the steps of a) preparing an aqueous, high solids slurry by gathering materials including crude titanium dioxide from the oxidation of titanium tetrachloride, a dispersant and water and then mixing the gathered materials to form an about 50 to about 70 weight percent slurry of the crude titanium dioxide solids in water, b) diluting the aqueous, high solids slurry by adding a further amount of water to the high solids slurry with mixing, the resultant, lesser solids slurry still containing at least about 50 percent by weight of crude titanium dioxide solids, c) media-milling the resultant aqueous, lesser solids slurry, d) recovering the media-milled, crude titanium dioxide product and e) finishing the media-milled, crude titanium dioxide product to produce a finished titanium dioxide pigment product.
