Finally, the article discussed the possible mechanism of multi-phase electrochemical degradation of wastewater through the XPS spectrum of the used catalysts surface: In the acid solutions, the electro-generated O_2 may get electrons on the porous graphite cathode and then form H_2O_2, H_2O_2 may diffused to the surface of catalyst and reacted with its active part to produce OH, which in turn can destruct organics. The catalyst functioned as both the catalyst to decompose H_2O_2 and the flocculants to sedimentate the degraded waste.

最后全文结合研究反应后催化剂表面的XPS光电子能谱推断了该体系降解污废水可能的反应机理:在酸性条件下,石墨双阳极产生的O_2被多孔扩散性石墨阴极还原成H_2O_2,并通过扩散传质作用在催化剂的表面活性中心分解为强氧化性中间产物·OH,强氧化性攻击有机物,使其降解为小分子有机物或CO_2和H_2O,催化剂在体系中即起催化作用也起吸附、絮凝作用。

Viral vector mainly contain adenovirus, retrovirus,adeno-associated virus and so on, but it has potential danger of safety; it isrepeled by immune system when it is injected to organism for a greatimmunogenicity. An injection with adenovirus vector with highconcentration, it leads to serious inflammatory reaction of liver. Viralvector such as liposome and polycation are commonly used lately. But,liposome and polycation have low specificness and targetness of genetransfer tissue, have lower transfection efficiency and short period ofgene expression, for they can be phagocytized by endothelial system.

许多的载体,病毒载体和非病毒载体以前已广泛应用,病毒载体主要包括腺病毒,逆转录病毒,腺相关病毒等;但病毒载体在安全性方面存在潜在的危险;免疫原性比较强,注射到机体后很快会被机体的免疫系统排斥,当静脉注射高浓度的腺病毒载体会使肝脏发生严重的炎症反应;非病毒载体目前常用的有脂质体及多聚阳离子聚合物;但脂质体和阳离子聚合物介导基因转移缺乏组织的特异性和靶向性,转染效率较低且易被网状内皮系统吞噬,基因表达时间短;因此研制新型的非病毒载体已成为研究的热点,纳米颗粒具有小尺寸效应,表面效应,随着颗粒直径变小,比表面积将会显著增大,故具有很高的化学活性,因而纳米成为了最有应用前景的非病毒载体。

For further understanding the effect of the strain on K-bearing silicate mineral, an experiment with KO2 strain cultured in nitrogen-containing and nitrogen-free medium was conducted. By putting mineral powders into the medium and measuring the concentration of capsular polysaccharides, we concluded that the strain can accelerate the weathering rate of silicate minerals. The results showed that the polysaccharides secreted by the strain in the growth process could help the bacterial to adhere to the mineral surface effectively, and created the bacterium-mineral complex, which formed a mircro-enviorment avail the release of potassium. Another result was that there was higher level of Carbonic Anhydrase activity, which revealed that some exo-protein or enzyme produced by the bacterial had postive impact on the process of releasing potassium ion. We carried out the bacterial fermentation for larger scale production of the bacterial secretion, which was used to sperate, and identify the small molecules related to the mineral-bacterial interaction. After the analysis, it was found that the strain can produce many kinds of small molecules, such as 2-Hydroxybenzoic acid, 4-Hydroxyphenylacetic acid, methyl-4-hydroxybenzoate, etc.
