奥巴马的外交(五) 奥巴马的东亚战略

<正>奥巴马执政以来,基本完成了以全面性接触为特征的东亚战略布局。2009年,国务卿希拉里进行了两次亚洲之行,几乎囊括了整个东亚峰会涵盖的重要国家,2月访问日本、印尼、韩国和中国,7月访问印度与泰国,并参加东盟地区论坛,显示美国既重视东亚地区内的关键国家,也没有忽视东南亚及东亚的多边机制。希拉里首访东亚,清晰传递了奥巴马政府重视东亚的信息,也有效巩固了美国与东亚盟国、中国及东南亚相关国家的

New secondary batteries and their key materials based on the concept of multi-electron reaction

Facing the significant applications in energy field, this paper introduces how to construct new high specific energy secondary batteries based on the concept multi-electron reaction and by designing multi-electron electrode materials. Recent progress on those new secondary batteries and their key materials based on the theory of multi-electron reaction are overviewed. Representative multi-electronic electrode materials, such as metal borides, metal fluorides, sulfur composite electrode materials and ferrates are briefly introduced, as well as the new secondary battery systems constructed with these materials. Thus gives the significance of the development based on multi- electron reaction mechanism of secondary batteries and their key materials for new chemical battery systems and related energy materials.     

理清辩证思路 促进机制更新——关于“产、学、研”结合机制的一点思考

<正>"产、学、研"相结合的发展机制,上世纪末就有人提出,也有人提"学、研、产"相结合,似乎各有侧重,前者强调"产"对"学、研"引领,后者强调"学、研"对"产"的支撑。不管顺序怎样,"产、学、研"相结合的思路是时代发展的要求,合乎我国科技进步、自主创新的实际需求,越来越多地受到各级政府的高度重视并得到积极推进。

Growth mechanism of liquid Hg/solid β-HgS metal-semiconductor heterostructures

Density functional theory （DFT） was utilized to simulate the reactions occurred in the mixture solution of cysteine and Hg（II） ions with the ratio 〈 2. Simulation result shows that Hg ions will coordinate to cysteine by the thiol groups with the form of S-Hg2 and S-Hg3; and moreover, the content of free Hg ions can only be reduced by these two forms. OH- plays an important role in the growth of β-HgS, because its nucleophilic substitution reaction supplies plenty of Hg-S-Hg radicals, which will be adsorbed onto the surface of liquid mercury ball and form the precursor of 13-HgS（111） plane. Three valent bonds adsorption of Hg-S-Hg radicals onto the surface of Hg ball has more adsorption energy （-32.768 kcal mol-1） than that of two valent bond adsorption （-20.882 kcal - mol-1）. Hg balls will stop growing after completely covered with Hg-S-Hg radicals and their size will be limited. The growth direction of β-HgS is parallel to the ＂repel- ling＂ force, that is [111] direction in β-HgS lattice. The calculated results are in good agreement with the experimental observations, demonstrating that the DFT method can be taken as a very useful tool to interpret the solution reactions that cannot be solved by conventional methods.

后勤社会化背景下的高校生活区学生组织运作机制探析——以湖州职业技术学院学生社区为例

高校扩招后,为适应现代化建设形势,深入推进后勤社会化改革,将单纯的学生寝室改造为学生生活区,融生活、学习、交流等功能于一体,在管理和运作上形成相对独立的区域。本文以湖州职业技术学院学生社区的运作模式为例,研究处于后勤社会化背景下的学生组织的发展现状、存在的问题及可能的解决方法。
