Gold extraction from oxide gold ores through glycine leaching
Revista de MetalurgiaThe use of glycine, a non-toxic and simple amino acid, has gained attention for gold extraction because of its selective dissolution of precious metals. This study explores gold extraction from oxide gold ore using non-analytical grade glycine at concentrations of 1-3 M and reaction times ranging from 4 to 60 hours. The pH was maintained at 11-12, with

Ti6Al4V‐Bioglass‐Copper Composites for Load‐Bearing Implants
Advanced Healthcare Materials, EarlyView.We have designed and manufactured a novel Ti64‐based composite by adding 45S5 bioglass (BG) and copper (Cu). Adding BG on titanium improves wear resistance and biocompatibility, whereas Cu addition improves mechanical strength while providing inherent lifelong bacterial resistance.
