Copper-based catalysts (Cu/ZnO and Cu/ZnO/Al2O3) are the basis of the industrial methanol synthesis and methanol oxidation and are important components of fuel cell technology. For the preparation of these catalysts, metal–organic chemical vapor deposition (MOCVD) technique has proven its potential. Furthermore, studying synergistic metal–support interactions, strategies can be developed to gai...
Copper nano/microparticles were synthesized in octadecene at 290 °C by thermal decomposition method. acetate monohydrate, stearic acid, and 1-octadecanol used as copper precursor, capping mild reducing agents, respectively, the synthesis. Borosilicate glass substrates submerged into reaction solution during synthesis coated nano/ microparticles. Thermal coating techniques combined this study. t...
Although the positive relationship between copper and Alzheimer's disease (AD) was reported by a lot of epidemiological data, the mechanism is not completely known. Copper is a redox metal and serves as a mediator of inflammation. Because the homeostasis of copper is altered in Aβ precursor protein (APP) and presenilin 1 (PS1) transgenic (Tg) mice, the using of copper chelators is a potential t...
The reaction of a silyl dienolate, Cu(II) salt and TBAT yielding the corresponding copper dienolate is addressed. A combined NMR cyclic voltammetry analysis first highlight role in to Cu(I) reduction structure precatalytic species. From these results second set theoretical studies enable determination mechanism formation catalytic Finally, we showed that catalyst promote E/Z s-cis/s-trans equil...
Zincian georgeite, an amorphous copper-zinc hydroxycarbonate, has been prepared by co-precipitation using acetate salts and ammonium carbonate. Incorporation of zinc into the georgeite phase and mild ageing conditions inhibits crystallisation into zincian malachite or aurichalcite. This zincian georgeite precursor was used to prepare a Cu/ZnO catalyst, which exhibits a superior performance to a...
nano structured materials have wide range of applications due to their interesting size-dependent chemical and physical properties compared to particles of size in the range of micrometer. copper oxide nano materials are of interest on account of their potential uses in many technological fields. in this study cuo nanoparticles were synthesized via simple sol gel method using basic cuso4 as we...

Previous attempts in producing light absorbing materials with bandgaps near the 1.37 eV efficiency optimum have included the partial substitution of gallium or aluminum for indium in the CIS system. The most efficient of these solar cells to date have had absorber layers with bandgaps < 1.2 eV. It is logical that an even smaller substitutional atom, boron, should lead to a wider bandgap with a ...
in this investigation, cuins2 ternary compound was synthesized by injection of thiourea solution into a hot copper-indium solution. the cucl, incl3 along with (sc (nh2)2) were used as a precursor dissolved in high boiling point solvent such as oleylamine (ch(ch2)17nh2) and oleic acid (ch(ch2)16cooh) as a coordination solvent and capping agent, respectively. the size, distribution and shape were...
