活性炭负载纳米零价铁去除溴酸盐的研究

实验采用液相还原法制备活性炭负载纳米零价铁材料(nZVI/AC),并利用X射线衍射(XRD)、扫描电镜(SEM)和透射电镜(TEM)等对其结构进行表征.考察了不同反应条件下nZVI/AC对BrO3-的去除效率,并研究其去除机理.结果表明nZVI/AC具有很高的表面反应活性,且nZVI和活性炭(AC)之间存在协同作用. BrO3-的去除效率随 pH 值的减小而增大, 共存离子NO3-和SO42-对其去除率影响不大但降低了去除速率.机理分析表明BrO3-被nZVI/AC吸附而使局部BrO3-浓度升高,并被nZVI迅速还原为无毒的Br-.     

Morphological control of zinc tricarbohydrazide perchlorate crystals: Theoretical and experimental study

The theoretical crystal-morphology of zinc tricarbohydrazide perchlorate (ZnCP) was studied using the morphology simulation software. The growth trends and surface characteristics were calculated using the Bravais-Friedel-Donnay- Harker (BFDH), Growth Morphology, and Equilibrium Morphology methods; these provide theoretical guidance for the choice of crystal-control reagents. On the basis of the simulations, experiments were carried out to study the effects of five different crystal-control reagents, including carboxymethylcellulose (A), polyacrylamide (B), dextrin (C), Tween 40 (D), and Tween 60 (E), in the control of the crystal-morphology of ZnCP. Mixtures of two reagents and higher temperatures were used to further optimize the ZnCP crystals. The results show that ZnCP crystals are well dispersed, and have a large apparent density and regular crystal-morphology under the control of a mixture of reagents A and E in a mass ratio of 1:4 at 80°C.

"以人为本"之"人"的科学内涵探析

科学发展观的核心是以人为本。“以人为本”之“人”不是专指或特指一些行业或部门中的某些人或某类人,更不是指那些损公肥私、损人利己谋取不当利益的人,而是指创造历史、推动历史发展的人民群众。厘清并把握“以人为本”之“人”的科学内涵,是准确领会科学发展观的精神实质,是贯彻落实科学发展观的前提条件。     

Proteome changes in the plasma of Papilio xuthus (Lepidoptera: Papilionidae): effect of parasitization by the endoparasitic wasp Pteromalus puparum (Hymenoptera: Pteromalidae)

Although the biochemical dissection of parasitoid-host interactions is becoming well characterized, the molecular knowledge concerning them is minimal. In order to understand the molecular bases of the host immune response to parasitoid attack, we explored the response of Papilio xuthus parasitized by the endoparasitic wasp Pteromalus puparum using proteomic approach. By examining the differential expression of plasma proteins in the parasitized and unparasitized host pupae by two-dimensional (2D) electrophoresis, 16 proteins were found to vary in relation to parasitization compared with unparasitized control samples. All of them were submitted to identification by mass spectrometry coupled with a database search. The modulated proteins were found to fall into the following functional groups: humoral or cellular immunity, detoxification, energy metabolism, and others. This study contributes insights into the molecular mechanism of the relationships between parasitoids and their host insects.
