Molybdophopsphoric Acid Catalysis in the Oxidative Cleavage of Olefins by the Hydrogen Peroxide Oxidative cleavage of the double bond could be catalyzed by H_3PMo_(12)O_(40) using H_2O_2 as oxidant, various trisubstituted olefins were oxidized to aldehydes or ketones in high yields. The system was not satisfied for electron-deficient olefins such as trans-(2-nitrovinyl) benzol or chalcone. The reaction of aliphatic olefins did not occur under the same conditions.

二、磷钼酸催化过氧化氢对烯烃的氧化断裂反应用过氧化氢(30％)作为氧化剂，磷钼酸可以催化氧化碳碳双键的断裂反应，三取代的烯烃被氧化生成醛或酮，产率较高；此体系对于缺电子烯烃如查尔酮，不饱和硝基化合物的断裂反应效果较差，脂肪族烯烃在此体系下的氧化并不发生。

Below its critical micelle concentration, SDS effect facilitated the energy transfer from the component at 232 nm to the tyrosyl residues in PS II proteins, and also resulted in less micropolarity for tyrosyl residues, whilst at or above its cmc, SDS had an opposite effect.

低于其临界胶束浓度时，SDS会促进蛋白质中232 nm外的组分与酪氨酸之间的能量传递，并且使酪氨酸残基外于极性更小的环境；而大于cmc时，SDS却产生相反的效应。

The analytes were extracted from alkalized plasma. ion pair extracted with TBAP further purified and concentrated by SPE method, derived and detected finally by GC/MS.

These results support that the supplement of histidine, cysteine and its derivatives might be helpful for attenuating different hepatotoxicity.

基於以上研究结果得知，组胺酸、半胱胺酸及其衍生物对於缓和肝损伤是有帮助。

The limiting substrate for GSH synthesis is the amino acid cysteine. Oral cysteine is rapidly catabolized in the GI-tract, carries a toxic potential, and is not recommended.

谷胱甘肽的关键基质是半胱胺酸，口服半胱氨酸在肠胃道内会被快速的代谢掉具有相当的毒性，因此不适于服用。

Lithium perfluoroalkylphosphonate was synthesized by LiF and perfluoroalkylphosphonate acid obtained by electrochemically fluorinating chlorodiisopropylphosphine. Some properties of a kind of electrolyte that was made from dissolving the lithium perfluoroalkylphosphonate in the mixed solvent with ethylene carbonate and dimethyl carbonate mass ratio 1∶1 were investigated, such as conductivity, stability toward hydrolysis and oxidative decomposition potential, and so on.

选取氯代二异丙基膦(C6H14PCl)为原料，利用电化学氟化方法，得到全氟烷基膦酸[(C3F7)2PF3]，(C3F7)2PF3与氟化锂反应得到全氟烷基膦酸锂Li[(C3F72PF4]，将其溶于碳酸乙烯酯和碳酸二甲酯质量比为1∶1的混合溶剂中得到电解液，考察电解液的电导率、抗水性及氧化分解电位。

With the established protocol, we were able to show that silencing COI1, an essential key player in the jasmonic acid signaling pathway, led to increase of R. solanacearum proliferation in stembases and mid-stems of 'Hawaii 7996', a tomato cultivar with durable resistance to BW. Our study provides the first demonstration for a positive role of the JA signaling pathway in tomato resistance to BW, and notably, is inconsistent with the reports in Arabidopsis. The involvement and possible interplays of other known defense signaling pathways in the tomato BW-defense network to R. solanacearum are discussed.

利用本文建立之静默系统进行茉莉酸防御讯息传递途径关键基因COI1之静默，结果发现青枯病菌在番茄抗病品种'Hawaii 7996'茎基部及中段内的菌量显著增加，显示茉莉酸防御讯息传递途径在番茄对青枯病的防御机制中扮演正面角色，此发现与阿拉伯芥对青枯病的防御机制研究所知的相反；文中并讨论其他防御讯息传递途径可能如何共同参与番茄青枯病防御网络。

The tail group of cysteamine containing amine moiety can easily protonize in acidic conditions. Heterpolyanions was successfully immobilized on such a positive-charged surface. By using quartinized conducting polymer containing osimium-bipyridine complexes, a sandwiching multilayers has been fabricated.

利用氨端基自组装膜在酸性条件下荷正电的特点，成功地将荷负电的杂多酸分子固定于其上，并在此基础上，通过荷正电的季胺化聚合物组装了多层的杂多酸修饰电极。
