Purpose. Research on the process intensification of gold-bearing product hydrometallurgical processing based mechanochemical milling initial sulphide material. Methods. Mechanochemical activating (oxidation) concentrate under conditions superfine milling, sulphite-thiosulphate leaching milled after liquid phase separation. The float sample with a particle size -0.074 mm, Au content is 15.5 g/t ...

Ratio blends of PLGA/PCL: (0:10), (1:9), (2:8), (3:7), (4:6), (5:5), (6:4), (7:3), (8:2), (9:1), and (10:0) were spin-coated to produce thin films; surface topographies were determined using interferometric microscopy. It was demonstrated that micro-wells of a defined size (150 mm) were present in all PCL dominant PLGA/PCL systems. Stratification of PLGA with PCL enabled the formation of that s...

A simple and eco-friendly route to gold–NHC complexes bearing different thiosugars is reported.
