Because of the special structure of mica crystal, nearly 1/4 Si4+ is replaced by the Al3+ in its silica tetrahedron layers, that makes the negative charges on the mica surface excessively.
Coupling agent is a kind of Silicone with organic functional groups, it is made of silicon chloroform and unsaturated olefin under the condition of catalyst after the addition reaction and the alcoholysis reaction, its structure formula is Y-R-SiX3.

Activated carbon (AC) of coconut shell has a typical performance of three-dimensional framework structure, environmentally friendly and stable electrochemical performanc.
The possible reason was that the three-dimensional pore structure had a strong adsorption effect on quercetin.

On the Determination of Content of 10 - DABIII in Enshi’s Taxus Chinensis Var Mairei Haiyan Wu1, a, XinPing Liu 2,b 1,2School of Chemistry and Environmental Science in Hubei Institute for Nationalities, Key Provincial Laboratory Biological Conservation and Utilization of Resources in Hubei Institute for Nationalities; Enshi Hubei aes569@163.com, bxingping-liu@163.com Keywords: Enshi’s taxus chinensis 10-DABIII content microwave extraction Abstract: Chemical semi-synthetic method for efficient low toxicity of paclitaxel analogues is the hot issue quite a long time in the present and the future of chemical, biological medicine and related interdisciplinary researches. 10-DABIII is the main precursor semi-synthetic raw materials.
At present, the related researches on it mainly focus on increasing its yield and perfecting its structure, improving its dissolution in water, and reducing its side effects, and so on.
Chemical semi-synthetic paclitaxel is one of the hot issues of the current related researches, that is, taking 10-Deacetylbaccatin III (10-DAB III) as the precursor material, modifying the structure of some active functional group in the side chains of the parent nucleus or C-13.

There have been a few attempts to control the grain boundary structure and chemistry of the ceramics by sintering surface-coated powders [3-5].
In this analysis, the lack of constituent elements in the inner region of grains is regarded as being caused by the presence of relevant vacancies and/or substitutional defects; it’s assumed that very little interstitial ions exist in the perovskite-structured grains.

For fixing agents with certain structure, molecular weight and charge density were the main factors influencing their performance.
Charge neutralization and coagulation were important factors for PDADMAC, but in some respects, the molecular weight and molecule structure had more effect on application behaviour.
