The temperature dependences of the reduction potentials (E degrees') of wild-type human myoglobin (Mb) and three site-directed mutants have been measured by the use of thin-layer spectroelectrochemist...
We explores Hamiltonian reduction in pulse-controlled finite-dimensional quantum systems with near-degenerate eigenstates. A quantum system with a non-degenerate ground state and several near-degenera...
Perovskite-type Pr2-xSrxCoO4\pm l mixed oxides were prepared by different calcination temperatures and were investigated by XRD, BET, TPD, TPR and XPS methods. These catalysts possess high catalytic a...
摘要 A combination of sodium borohydride and a catalytic amount of indium(III) chloride in acetonitrile reduces imines formed in-situ from aldehydes and amines to the corresponding functionalised second...

期刊信息 篇名 The reduction of cycling capacity degradation of Mg-Ni-based electrode alloys by Fe substitution 语种 英文 撰写或编译 作者 Zhang Yao, Chen Li-xin, Lei Yong-quan 第一作者单位 刊物名称 Int. J. of Hydrogen Energy 页面 ...
采用羰基金属化合物低温合成法制备了不同掺杂元素的M-Ru-Se(M=Fe,W,Mo)簇合物,并应用旋转圆盘电极电位扫描法测试簇合物的电催化活性及其抗甲醇性,采用TEM、XRDEDS技术表征催化剂的微观形貌、结构和组成。结果显示,掺杂过渡元素对簇合物的催化活性及其抗甲醇性有明显的影响,其中Mo-Ru-Se的还原电流最高,催化活性最高,W-Ru-Se次之,Fe-Ru-Se最低;电解质中加入甲醇后,W...
The effect of platinum loading on the performance of oxygen reduction over Ru-based cluster catalyst in acid electrolytes has been studied by rotating disk electrode. The Pt-Mo-Ru-Se catalysts were s...
采用微波加热合成法制备了CoTMPP/BP电化学氧还原催化剂。采用旋转圆盘电极(RDE)研究了BP2000碳载体经30% H2O2或6 mol·L-1 HNO3化学预处理后对催化剂氧还原催化活性的影响,并且在PEM燃料电池工作站上测试了不同CoTMPP/BP催化剂的燃料电池单电池性能。结果表明,碳载体经过化学预处理后催化剂性能有显著的提高,并且30% H2O2处理效果更好。采用IR、XRD和XPS...
Reductions of benzene, toluene, ortho-xylene, cumene, anisole and benzoic acid to corresponding nonconjugated dienes were realized at room temperature by gas NH3 and Li. The reduced products were easi...
A simple, sensitive and rapid spectrophotometric method for the determination of tinidazole (TZ) and metronidazole (MZ) in pure as well as in dosage form is described. The method is based on the reduc...
It was observed that in toluene solution, excess 1-methyl-imidazole (Melm) reduces dichloro 5, 10, 15, 20 tetraphenyl-porphinatoplatinum(IV) (PtTPPCl2) to tetraphenylporphinato-platinum(II) (PtTPP) au...
