The reaction couple can be regarded as a semi-infinite diffusion couple and the growth rates for the intermetallic copper-zinc compounds ?, ?, and ? are determined for the chosen boundary conditions. The structures of the reaction zones are described. From the kinetics of the system it is ...
Principal component analysis (PCA) reveals that wurtzite-type phase is the major cationic zinc component in this system (Supplementary Figs.5and6, Supplementary Note 1). Besides the partial oxidation of the copper–zinc alloy after switching to the CO2/H2reaction mixture, an immediate formation of...

摘要: ► Cu is efficiently leached from copper-zinc waste by H2SO4 solutions with Fe3+ ions. ► Fe3+ ions inhibit zinc and iron leaching from converter slag flotation tailings. ► Copper and zinc leaching is controlled by chemical reaction on the particle surface....
A full-length cDNA of 803 base pairs encoding a putative copper/zinc−superoxide dismutase (Cu/Zn-SOD) from Epinephelus malabaricus was cloned by the polymerase chain reaction approach. Nucleotide sequence analysis of this cDNA clone revealed that it comprises a complete open reading frame coding ...

COBALT(II), NICKEL(II), COPPER(II) AND ZINC(II) COMPLEXES OF 14 TO 16-MEMBERED TETRAAZAMACROCYCLES BEARING DIAMIDE GROUPS - SYNTHESIS AND CHARACTERIZATION A new series of 14 to 16-membered tetraazamacrocyclic complexes bearing diamide groups have been prepared by the condensation reaction of o-...
Heavy metals are essential for many organisms in trace amounts, but they may become toxic in high concentrations12. Coexistence of antibiotics and heavy metals, including copper (Cu), zinc (Zn), cadmium (Cd), chromium (Cr), and lead (Pb) have been detected with high concentrations in waste...
The copper- and zinc-containing superoxide dismutase can catalyze the oxidation of ferrocyanide by O⨪2 as well as the reduction of ferricyanide by O⨪2. Thus, it can act as a superoxide dismutase (SOD), a superoxide reductase (SOR), and a superoxide oxidase (SOO). The human manganese...
