Preparation of a mesoporous sorption complex catalyst and its evaluation in reactive sorption enhanced reforming

A mesoporous sorption complex catalyst was prepared by pore-forming modification and evaluated by the COz reactive sorption enhanced reforming （ReSER） process, which is used to produce hydrogen from methane. Three samples of polyethylene glycol （PEG） with molecular weights between 2000 and 20 000 were added as templates into a mixed slurry to create catalysts with different pore properties by further formation and calcination. The pore characteristics determined by Brunauer- Emmett-Teller （BET） analysis showed that one of the mesoporous catalysts, named M-NiAICa-6000, had a pore size of 9.2 nm and a surface area of 70.52 m2/g and the CO2 sorption capacity of this catalyst was 44% higher than that of the catalyst without the PEG 6000 modification. The catalyst was evaluated in the ReSER process in a fixed-bed reactor system at 0.1 MPa and 600 C with an H20/CH4 molar ratio of 4. An H2 concentration of 94.2% and a CH4 conversion of 86.0% were obtained at a carbon space velocity of 1700 h 1 while CO2 was hardly detected.     

Longest Paths and Cycles in Connected Claw-Free Graphs

A graph is called claw-free if it does not contain a claw as its induced subgraph. In this paper, we prove the following results : 1 ) If G is a 2-connected claw-free graph on n vertices, then for any vertex υ and any two distinct vertices x and y in V(G) - |υ| , G has a path containing v and all neighbors of v and connecting x and y;2) Let C be the longest cycle in a 3-connected claw-free graph G and H a component of G - C,and if H is connected but not 2-connected, then there exist nonadjacent vertices u and v in H such that |V(C)| ≥3(d(u) d(u)) -2.

苯和溴取代反应实验的改进

中学课本中介绍苯的取代反应性质时是以苯和溴反应为例进行实验的．若按课本上的装置和操作，将苯和溴混和好后，再加入催化剂——铁粉，烧瓶内液体急剧沸腾，大量的溴蒸气和溴化氢气体充满烧瓶上面的空间，并通过长导管进入锥形瓶，进一步弥漫到空气中，产生呛人的白雾和窒息的恶臭，造成严重的污染，锥形瓶中的蒸馏水也会因溶有溴呈棕黄色，这时再用AgNO3溶液来检验蒸馏水中的溴离子缺乏说服力．另外，实验结束后，把烧瓶内生成物倒入水中，生成的溴苯因溶有溴而呈褐色，尽管在教学中强调是因为溶有溴而发生了颜色变化。     

人-自观念演进的否定之否定

以列维纳斯爱的伦理观解读《奥赛罗》中的人物形象

《奥赛罗》以嫉妒、盲目、报复为主题展现人类在命运面前的无能与无助。列维纳斯的伦理观把爱作为伦理的基础,强调他者的不可知性和他异性是自我对他者回应和负责的根本原因。只有忘我的以他者为中心、对他者敞开心扉才能让爱的伦理关系存在并延续。借助列维纳斯的爱的伦理观阐释《奥赛罗》三位主要人物对爱的不同处理方式,可以揭示出导致人物之间伦理关系破灭和导致的爱消失的原因,再现莎士比亚这位文学巨匠的超前历史眼光与社会责任感。     

加州大学的治理变革及启示

从控制走向协调,以治理代替管理,既是世界高等教育改革的趋势,也是美国公立大学一直努力的方向,而加州大学则是将这种努力践行得较为彻底的一个成功典范.这种努力具体表现为加州大学一方面通过与政府签订协约、引入市场机制、寻求校外群体的支持等形式来弱化政府的管制色彩,另一方面又充分发挥董事会、学术委员会等治理机构的协调作用,为大学自治提供一系列的缓冲与保护.     

艺术作品本源的存在之思——对《艺术作品的本源》中几组概念的阐释

从存在主义哲学的角度出发,海德格尔寻找艺术作品的本源,对作品、艺术和本源的概念层层分析之后,最终发现并没有一个外物可以赋予艺术以本源,而艺术就是自身的起源,这一结果恰恰揭示了海德格尔对于存在和存在物的差异性思考。他把一切事物都纳入到其存在论哲学框架中,把人当作世界讲述自己的一个媒介,唯有如此才能以体验的方式接近艺术的本质,这也正是他存在主义艺术论的目的和意义。
