Enhanced leaching of manganese from low-grade pyrolusite using ball milling and electric field
Ecotoxicology and Environmental Safety, 2021 In this study, electric field and ball milling were used to leach Mn2+ from low-grade pyrolusite (LGP). The effects of current density, reaction time, reaction temperature, ball-to-powder weight ratio, and ball milling time on the leaching efficiency of ...

A Ball Milling Enabled Cross-Electrophile Coupling [PDF]
Organic Letters, 2021 The nickel-catalyzed cross-electrophile coupling of aryl halides and alkyl halides enabled by ball-milling is herein described. Under a mechanochemical manifold, the reductive C-C bond formation was achieved in the absence of bulk solvent and air/moisture sensitive setups, in reaction times of 2 h. The mechanical action provided by ball milling permits
