Abstract: To avoid the high purity reagents and high energy consumption involved in the manufacturing of lithium-ion battery anode materials, Sb2S3 nanorods/porous-carbon anode was prepared... conductivity. However, the reported Sb2S3-based anode materials were largely synthesized with high-purity metal or metal salt as the raw materials, thereby inevitably extending the preparation duration......
in annealed Cu/Sn bulk couples with high-purity Cu and Sn plates. Their result implies that void formation is primarily due to the Kirkendall effect, as a result of the imbalance in migration... changes the electrical characteristics of the interconnects because these compounds, in general, are brittle and have high electrical resistivities[7-8]. The microstructure and phase composition......

A biomaterial has to possess the attributes of suitable properties, excellent biocompatibility, high corrosion resistance, high wear resistance and osteointegration [2]. 70%-80% of implants are made of metallic......
presented in the raw material or oxides formed during grinding. High-purity (>99%) natural calcite and dolomite were used in this study. All other chemicals were used in analytical grades. Fig. 1... oxidation can be a possible alternative to acidic oxidation specifically in the case of high carbonate refractory gold ores to avoid high acid consumption and also to suppress elemental sulfur formation......
process is suppressed by increasing c((NH4)2SO4) at high over-potential, at which the formation of columnar grains with higher hydrogen contents becomes prevailing. Key words: ammonium sulfate; manganese electrodeposition; hydrogen evolution; stainless steel cathode 1 Introduction Electrowinning (EW) is preferably used for extracting high-purity manganese (Mn) from aqueous solution [1,2......
