Novel bio-relevant monometallic Schiff base complexes of the type, [Cu(L-1)(2)] (1), [Zn(L-1)(2)]center dot 2H(2)O (2), [Cu(L-2)(2)]center dot 2H(2)O (3) and [Zn(L-2)(2)]H2O (4) [L-1 =(E)-3-( ( (3-chloro-4-hydroxyPhenyl)imino)methyl)naphthalen-2-ol ...
The evolution of the structure of a flexible Cu-MOF, {[Cu(bpy)(H2O)2(BF4)2](bpy)} (bpy = 4,4′-bipyridine), upon dehydration and rehydration was studied by thermogravimetric analysis (TGA), infrared (IR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and ...
Ab initio studies on the structures and vertical electron detachment energies of copper-water negative ion clusters Cu(H2O)n and CuOH(H2O)n1 The equilibrium geometries of Cu (H O) and CuOH (H O) ( n=1 and 2) negative ion clusters have been optimized by performing ab initio calculations ...
[Cu(cyc len)(H2O)]2+(cyc len=1,4,7,10-四氮杂环十二烷)是一种新型的大环配合物.在其实验所测晶体结构基础上,文章运用量子化学密度泛函理论中的B3LYP/6-31G(d)方法,对其结构参数进行优化和频率分析,结果表明优化结构为稳定结构,且与实验吻合良好.最后,对配合物的前沿分子轨道及自然电荷布居进行了分析....
The high H2O and oxidation state inferred for the Kal-e-Kafi adakitic magmas, which increased SO2/H2S ratios (Burnham, 1979), give them considerable ore-forming potential, because they keep ore-forming components, such as Cu, Au, and S, in the melt, enabling them to partition efficiently ...
Formate stability Charge transfer Hybridization Non-axial Cu d–orbital 1. Introduction Formate is a key stable intermediate, which is directly involved in many industrially important reactions for example in the synthesis of methanol from syngas (H2/CO2/CO) [1], [2]. In this reaction, the for...
即猝灭剂浓度降低,FAM-DNA的荧光强度又有所增加.结果表明,荧光强度的增加值会受反应时间,维生素C浓度等的影响.针对实验各个条件进行优化.在优化后的条件下,利用荧光光谱建立了一种较为简单的检测Cu^2+浓度的方法,在Cu^2+浓度为5.0×10^-9 mol/L^-1×10^-6 mol/L的范围内,有较好的线性关系,相关线性系数r...
H2O absorption can also be excluded because it is again not possible to account for the suppression of the complete crystal. Such conjecture is reasonable because the crystals are sealed in vacuum during ageing. The STM measurements are able to reveal the presence of defects and yield more ...
(C9H3O6)2(H2O)3]}n, aka Cu-BTC) is one of the very first permanently porous MOFs, which has been widely studied for multiple applications [12–14] The microporosity and tunable functionality of MOFs make them ideal template precursors to fabricate various transition...
(ZnO NPs, dispersion 20 wt. % in H2O), hexamethylenetetramine (HMTA, purity >99%), Zinc nitrate hexahydrate (Zn(NO3)2·4H2O, 99%), Copper(II) nitrate hydrate (Cu(NO3)2.H2O, 99.999%) were purchased from Sigma-Aldrich. Gold pellets evaporation materials (Au, purity of 99.99%) were ...
