摘要:
The present invention relates to a new synthetise for the preparation of mesoporous structures including mesoporous materials with chiral morphologies and mesoporous materials with localor surface chirality. The method can be used for manufacturing controlled drug delivery devices, for example for delivery of folic acid, and fluorescent particles.
摘要:
A sample preparation material is described for supporting sample preparation procedures, such as solid phase extraction (SPE). The present sample preparation material is useful as a sorption media which is highly and selectively retentive for various analytes of interest. The sorption media is prepared by carbon deposition on target substrates, wherein the deposited carbon substantially covers the substrate. In some embodiments, the substrate may be porous particles, which retain their porosity subsequent to carbon deposition.

Zirconium phosphate particles are synthesized by providing a solution of zirconium oxychloride in an aqueous solvent, adding at least one low molecular weight, oxygen containing, monofunctional, organic additive to the solution, and combining this solution with heated phosphoric acid or a phosphoric acid salt to obtain zirconium phosphate particles by sol gel precipitation.

摘要:
The invention is a device for purifying drinking water that has at least one fibrous structure. Preferably, there is an upstream and downstream fibrous structure. Each fibrous structure is a mixture of nano alumina fibers and second fibers arranged in a matrix to create asymmetric pores and to which fine, ultrafine, or nanosize particles are attached. Preferably, the device has an upstream antimicrobial for sterilization of retained microbes. The device is substantially more efficient at removing soluble contaminants such as halogens from a fluid stream than those previously available and is also able to retain turbidity, bacteria, and virus.

The present invention concerns a novel additive composition for reducing sulfur content of a catalytically cracked gasoline fraction. This additive composition comprises a support consisting of porous clay into which a first metal from group IV is incorporated and a second metal from group II is impregnated. Preferably, the first incorporated metal is zirconium and the second impregnated metal is zinc. The sulfur reduction additive is used in the form of a separate particle in combination with a conventional fluidized catalytic cracking catalyst in a fluid catalytic cracking process to convert hydrocarbon feed stocks into gasoline and other liquid products.
