carboxylato–Cu(II) complexes of type [Cu2(RCOO)4] and their benzothiazole adducts [Cu2(RCOO)4bt2] (bt = benzothiazole, R = CH3(CH2)n−2, n = 12, 14, 16, 18) form the main objectives of this study. The studied carboxylato–Cu(II) complexes are formed from dimeric units to polymeric chains (chromofor CuO5). The structural changes are due to coordination of ligand (benzothiazole). The polymeric chains of carboxylato–Cu(II)

Abstract Results are presented on the temperatures, enthalpies, and entropies of the phase transitions of the even chain length copper(II) carboxylates from decanoate to octadecanoate. The dodecanoate, tetradecanoate and hexadecanoate melt directly from crystal to isotropic liquid. However, with the decanoate and octadecanoate, an intermediate phase is observed between solid and isotropic liquid. Tentative
摘要 给出了偶数链长羧酸铜 (II) 从癸酸到十八酸的相变的温度、焓和熵的结果。十二酸、十四酸和十六酸直接从晶体熔化成各向同性液体。然而,对于癸酸酯和十八酸酯,在固体和各向同性液体之间观察到中间相。对中间阶段进行了初步分配。报告了固体羧酸铜 (II) 的电子和红外光谱。在这两种情况下,光谱都提供了清晰的证据,证明每个羧酸铜系统的头基区域中至少有两个铜离子。

simple one-step electrodeposition process is developed for the fabrication of superhydrophobicsurfaces on a series of substrates such as copper, titanium, iron, zinc, aluminum, and stannum. The hierarchical micro- and nanostructures endow these surfaces with excellent super-hydrophobicity and the resulting surfaces show superhydrophobicity even for some corrosive liquids including salt solutions and

metal-based material as the electrocatalyst in the oxygen reduction reaction has gained great attention for fuel cell application. In this report, a facileapproach has been developed for the synthesis of copper myristate strips. The as-synthesized material has demonstrated its electrocatalytic activity towards oxygen reduction reaction. This study opens up a new scope for the use of straight chain copper
