Abnormal Infrared Effects (AIREs) of nm-Ru/GC Electrode Towards CO Adsorption in Alkaline Solutions

研制纳米级厚度的Ru薄膜电极 ,并运用电化学原位FTIR反射光谱研究碱性介质中CO的吸附。检测到CO以线型吸附态为主 ,但也存在少量桥式吸附态 ,分别在 196 0和 1780cm-1附近给出红外吸收谱峰。发现纳米Ru膜电极具有异常红外效应 ,即CO谱峰方向倒反 ,强度增强和半峰宽增加。测得在碱性溶液中吸附态CO的红外吸收被增强了 33倍 ,其增强因子是酸性溶液中的两倍左右。The adsorption of CO on electrode of nanometer thin film of Ru in 0 1 mol·L -1 NaOH solution was studied by using in situ FTIR spectroscopy.The results revealed that the adsorbed CO in alkaline solutions is mainly in linear bonded form that yields IR absorption at around 1 960 cm -1 ,and a small portion of bridge bonded CO was also determined near 1 780 cm -1 .The band centers of CO L and CO B have been red shifted respectively about 50 and 60 cm -1 in comparision with the values measured in acid medium.The enhancement factor of IR absorption of CO on nm Ru/GC electrode has been measured at 33 in 0 1 mol·L -1 NaOH solution,which is more than 2 times larger than the value determined in a 0 1 MH 2SO 4 solution.国家自然科学基金!(2 98330 60 );; 教育部科学技术重点研究项目!(991 77)资

电视新闻收视率:质量为王——美国地方电视新闻质量危机调查报告

美国的地方电视新闻已经走到了十字路口。观众正在放弃传统媒体,更多地转向了因特网。正如10年前,有线电视的出现导致电视新闻网失去了大量的观众一样。然而电视工业对此所做出的反应却使它走上了一条致命的错误之路。一项针对美国地方电视台新闻的研究揭示出这样一种情况:现在地方电视台新闻节目的经营方

Abnormal infrared effects (AIREs) of nm-Ru/GC electrode towards CO adsorption in alkaline solutions

The adsorption of CO on electrode of nanometer thin film of Ru in 0.1 mol.L-1 NaOH solution was studied by using in-situ FTIR spectroscopy. The results revealed that the adsorbed CO in alkaline solutions is mainly in linear bonded form that yields IR absorption at around 1 960 cm(-1), and a small portion of bridge bonded CO was also determined near 1 780 cm(-1). The band centers of COL and COB have been red-shifted respectively about 50 and 60 cm(-1) in comparision with the values measured in acid medium. The enhancement factor of IR absorption of CO on nm-Ru/GC electrode has been measured at 33 in 0.1 mol.L-1 NaOH solution, which is ;more than 2 times larger than the value determined in a 0.1 MH2SO4 solution

生物行为变化研究的新模式——工蜂

蜜蜂群体由1只蜂王、几百只雄蜂和数千只工蜂组成,工蜂数量巨大,除蜂王和雄蜂共同完成生殖任务,巢内外活动均由工蜂完成,其行为呈现多样性。工蜂发育经过卵、幼虫、蛹、成虫4个阶段,其活动范围由温度、湿度相对稳定的巢内环境发展到复杂的巢外自然环境。随发育阶段和生活环境的变化,工蜂的生理、行为等方面也发生相应变化,这种变化为综合研究生物行为的分子机理提供了可能。又因工蜂数量多、体积较大易于观察、标记、饲养管理简单,而且目前对其形态、发育、生理、分子生物学、神经、社会生态等各方面的研究比较充分,所以工蜂成为研究生物体行为变化、发育机理和个体与群体关系的理想模式生物。该文介绍工蜂活动由巢内发展到巢外时出现的一系列变化以及部分变化的机制,主要包括行为的变化、激素的分泌、代谢活动、飞行能力、神经系统等
