A three electrode-measurement unit with 33 microdisk electrode-array (MDA) as working electrode was constructed by lithograpy. Its electrochemical behavior was observed. The results of the oxidation of ferrocene in CH3CN-H2O mixed media demonstrate that high quality electrochemical data for the system without supporting electrolyte can be achieved with the MDA unit constructed in the present work.

ACCORDING to Tanabe’s definition, all materials possessing the basic strength （H-） over 26.5 are superbases. However, most of superbases known up to now, including CaO and SrO evacuated at 1173 K, K or Na metal supported on KOH/γ-Al2O3, etc. are extremely sensitive to CO2 or H2O in the atmosphere, which limits their application in industrial scale.

Abstract: KF/Al2O3 reached maxinmun activity at the pretreatment temperature(Tp) of 623K or 723K in Ibuters isomerization at 273K. according to the amount of KF loaded. Further increment of Tp lowered the activity of KF/Al2O3 due the suppression of [Al-OHF]strong basic sites through dehydroxylation. Changes in the state and function ofF caused the deactivation of KF/Al2O3 at high Tp.

目的:了解缺氧诱导因子1αmRNA和蛋白质在大鼠急性缺血心肌组织中表达的变化规律。方法:实验在南通大学生物技术系,江苏省神经生物学重点实验室完成。①实验分组:雄性SD大鼠78只,其中42只大鼠随机分为7组,每组6只,分别设为空白对照组(0h)和缺血0.5h,1h,1.5h,2h,3h,4h组,检测缺氧诱导因子1αmRNA表达变化。另外36只大鼠随机分为6组,每组6只,分别设为空白对照组(0h)和缺血1h,2h,4h,5h,6h组,检测缺氧诱导因子1α蛋白表达变化。②实验方法:通过结扎大鼠左冠状动脉前降支,构建左室心肌缺血模型。术中心电图等证明结扎成功后,分别在上述不同时间点取缺血心肌组织,分别运用反转录聚合酶链式反应法和免疫组织化学方法检测缺血心肌组织中缺氧诱导因子1αmRNA和蛋白质的表达变化。结果:缺氧诱导因子1αmRNA和蛋白质在正常大鼠心肌中微量表达,心肌缺血后表达明显增高,并随缺血时间变化而变化。0.5h缺氧诱导因子1αmRNA表达显著增加(P<0.05),1.0～2.0h达到高峰(P<0.01),以后逐渐下降并趋向基线。心肌缺血后1h缺氧诱导因子1α蛋白质表达明显上升(P<0.05),4h达到高峰(P<0.01),随缺血时间延长表达回降。结论:缺氧诱导因子1α在缺血心肌组织中高表达。缺氧诱导因子1α在大鼠缺血心肌组织中表达的上调,可能参加了心肌缺血的代偿机制,有助于改善心肌供血。

The present paper covers the reactions of M￣+ +CH_4→M￣+CH_2+H_2(M=Sc,Y,La)investigated theoretically using ab initio MO methods and reaction channels onthe singlet potential energy surfaces (PESs) examined and discusses the reactionmechanism. The results indicate that the formation of M￣+CH_2 is primarily via a sin-glet H M￣+ CH_3 intermediate,followed by a four-center elimination of H_2,all ofthese reactions have negative activation energies and the trend of reactivity is La￣+>Sc￣+>Y￣+.
