An equal-molar mixture of silver chloride (AgCl) and copper (Cu) was ground in atmosphere conditions using a planetary ball mill to investigate mechanochemical (MC) reaction for preparation of silver powders. The reaction causes the mixture of AgCl and Cu to change the composition of the mixture, such as silver (Ag) and cuprous chloride (CuCl). Through the leaching with ammonium hydroxide solution (1 mol), CuCl can be separated from MC product, so that pure Ag powders can be obtained as the final product. Moreover, polyvinylpyrrolidone (PVP) was used as the additive not only to improve dispersion of Ag pow- der during MC process, but also to control surface oxidation of Ag powders, prepared as the final product.

This study thus set out to empirically analyze connections between the success factors of marketing and management performance in the silver industry. For that purpose, the investigator analyzed relations between independent variables, which include such success factors of marketing as market segmentation, product mix, customer relational management, brand asset, price strategy, and marketing information system, and dependent ones, which include financial and non-financial management performance. Those results partially support the hypothesis that the six success factors of marketing set in the study have effects on financial and non-financial management performance in the silver industry. Customer relational management had the biggest influence, being followed by brand asset and price strategy in the order. Those results indicate that companies need to consider customer relational management, brand asset, and price strategy before other success factors of marketing to achieve financial and non-financial management performance in the silver industry.

The extraction of precious metals from aqueous solutions is performed by using a photoredox reaction with a Q-switched Nd:YAG laser. The metallic silver was efficiently precipitated and extracted from the silver nitrate solution by laser photolysis. An optimum reaction condition for silver extraction was determined by adjusting various experimental factors such as type of reducing agent, type of acids and reaction time. The composition of the reaction product was analyzed and it was identified as metallic silver, not other molecular types. The photoreaction of chromium(III) chloride in an acidic aqueous solution was also investigated. The 355 nm laser light was better suited for the reaction of silver nitrate as well as chromium(III) chloride in an acidic solution compared to the 532 nm light.

This study was aimed to investigate the antibacterial efficiency of silver nano-particles and the dyeing properties of a brushed warp-knitted fabric. The properties of the brushed warp-knitted fabric containing silver nano-particle by field production processes were evaluated by analyzing its silver contents, antibacterial activity, color difference, exhaustion curve, fastness and tearing strength. Bacterial reduction ratio amounts to 91.4 and 99.9 for Staphylococcus aureus and Klebsiella pneumoniae respectively. As the brushed pile length of its fabrics is longer, the exhaution rate of disperse dye becomes higher. The brushing process of its fabrics reduces the tearing strength. The results indicate that the brushed warp knitted fabric containing silver nano-particle can be a practically promising product.
