Formation of mixed copper sulphide and silver sulphide layers on low density polyethylene film

The influence of sulphide transport on the growth and properties of copper sulphide films on copper

A Novel Technique for Silver Extraction from Silver Sulphide Ore

A novel technique for silver extraction from Ag2S is described. The method utilizes thiosulphate as complexing reagent and the redox reaction between SO2 added as Na2SO3 powder and H2S gas evolved. The parameters of the reaction such as pH, the reaction temperature, the complex equilibrium of Ag ion with thiosulphate and the solubility of Ag2S were investigated. Silver ions, obtained by this me...

Key parameters determining structure and properties of sulphide films formed on copper corroding in anoxic sulphide solutions

The corrosion behaviour of copper was studied in anoxic solutions containing different concentrations of sulphide (10–10 mol L) and chloride (0?1–5 mol L) under stagnant and controlled convective conditions. The main determinants of the structure and properties of the copper sulphide (Cu2S) films formed are the rate of sulphide transport to the surface relative to the rate of its interfacial re...

Colloidal synthesis and characterizations of wittichenite copper bismuth sulphide nanocrystals.

Wittichenite (Cu(3)BiS(3)) nanocrystals have been synthesized utilizing a hot-injection method. They have been characterized in detail. Cu(3)BiS(3) nanocrystals possessed a band gap of 1.56 eV, and the corresponding nanocrystal-film shows a clear photoresponse in I-V measurements. Our work illustrates that Cu(3)BiS(3) nanocrystals have potential in the application of solar cells.
