In this study we present a three-step process for the low-temperature chemical bath deposition of crystalline ZnO films on glass substrates. The process consists of a seeding step followed by two chemical bath deposition steps. In the second step (the first of the two bath deposition steps), a natural polysaccharide, namely hyaluronic acid, is used to manipulate the morphology of the films. Pre...

Leaching mechanism of zinc oxide is important not only to understand zinc smelting process but also to develop of new zinc recycling process. Recycling of zinc is mainly done by treatment of electric arc furnace dust (EAF dust). In Japan pyro metallurgical process is enhanced for EAF dust treatment, however only zinc oxide can be recovered by pyro metallurgical process. Hydro metallurgical proc...

cutaneous lesions in fishes due to viral, bacterial, parasitic, mechanical and chemical agents are very common, leading to severe infection and high mortality. the aim of this research was to investigate the effect of long term bath of zinc sulfate (15 and 23 ppm), healing of cutaneous lesions caused by surgical incision in carps. in this study, 210 carps were disinfected by 3% salt solution fo...

Thin films of zinc sulfide (ZnS) with different concentrations acetate have been made by chemical bath deposition technique in acidic medium (pH = 5) on glass substrate using and sodium as sources Zn+2 ion S?2 ion, respectively, ethylenediaminetetraacetate complexing agents sulfuric acid to adjust pH value at a constant temperature 85°C, the time 90 minutes was used. The effect concentration me...

Two histidines are known to be essential for zinc potentiation of rat P2X2 receptors, but the chemistry of zinc coordination would suggest that other residues also participate in this zinc-binding site. There is also a second lower affinity zinc-binding site in P2X2 receptors whose constituents are unknown. To assess whether the extracellular acidic residues of the P2X2 receptor contribute to z...
