标题:过氧化氢在功能化介孔二氧化硅表面的吸附
摘要:Mcm-41 和 Msu-H 介孔二氧化硅成功地通过氢键功能化形成有机部分,这已通过元素分析得到证实.基于含氧和含氮基团的两个部分均以高效率引入--在所有情况下,碳含量均超过 10%,元素比率表明通过两个或三个 Si-O-Si 键与表面结合.过氧化氢吸附在其水溶液中进行,吸附量采用硫氰酸铁法测定.结果显示为水溶液中过氧化氢浓度为 5% 至 30% 的函数.与未官能化的类似物相比,两种官能化的二氧化硅都显示出更高的吸附能力.用氮基有机部分改性的表面显示出更好的吸附性能以及更高的抗氧化性.Msu-H 二氧化硅,由于其较大的孔径,提供了更多的空间来结合过氧化氢分子,因此被发现具有更高的吸附能力:它吸附的过氧化氢比 Mcm-41 多四倍.

标 题 :Solid phase peptide synthesis on silica

权利人:JOHNSON MATTHEY PLC; GROARKE MICHELLE
摘要:A method for peptide synthesis is described, comprising steps of forming an organofunctional silica by reaction of an alkyl silicate, an organofunctional silane and water, optionally in the presence of a template compound; removing the template compound if present; reacting said organofunctional silica with a first protected amino acid to produce a tethered protected amino acid; deprotecting the tethered protected amino acid; reacting at least one further protected amino acid with said tethered deprotected amino acid to form a tethered peptide, and removing the peptide from the organofunctional silica. Preferably, prior to reaction of the first protected amino acid, the organofunctional silica is reacted with at least one linking compound to form a linker-modified organofunctional silica with which the first protected amino acid is reacted. A method for preparing an organfunctional silica by the co-hydrolysis of an alkyl silicate and an organofunctional silane is depicted below. The wavy line represents the silicon atom on or within the resulting silica material formula (I). A reaction of a protected amino acid with an organofunctional silica to provide a tethered protected amino acid is depicted below formula (II).

摘要:Provided is a semi-aromatic polyamide, comprising, on the basis of the molar content of all repeating units, the following repeating units: 46‑54 mol% of 10T unit derived from 1,10‑diaminodecane and terephthalic acid, 46-54 mol% derived from one or more monomers in diacid Y containing 4-36 carbon atoms, and XY unit consisting of one or more monomers in diamine X containing 4-36 carbon atoms; the 10T unit and XY unit in the semi-aromatic polyamide chain segment are arranged in an alternating order ... 10TXY10TXY10TXY 10TXY10TXY ...; the semi-aromatic polyamide at least contains three monomers. In the semi-aromatic polyamide prepared by means of the special preparation method, 10T and XY units are arranged alternately, and in comparison with ordinary random copolymerized semi-aromatic polyamides, it has higher crystallinity and a higher melting point, and the water absorption rate is low.

摘要:A method of making a molecularly imprinted porous structure makes use of a surfactant analog of the molecule to be imprinted that has the imprint molecule portion serving as the surfactant headgroup. The surfactant analog is allowed to self-assemble in a mixture to create at least one supramolecular structure having exposed imprint groups. The imprinted porous structure is formed by adding reactive monomers to the mixture and allowing the monomers to polymerize, with the supramolecular structure serving as a template. The resulting solid structure has a shape that is complementary to the shape of the supramolecular structure and has cavities that are the mirror image of the imprint group. Similarly, molecularly imprinted particles may be made by using the surfactant to create a water-in-oil microemulsion wherein the imprint groups are exposed to the water phase. When reactive monomers are allowed to polymerize in the water phase to form particles, the surface of the particles have cavities that are the mirror image of the imprint group.
