Ball Milling Towards Green Synthesis RSC Publishing

Ball milling has emerged as a powerful tool over the past few years for effecting chemical reactions by mechanical energy. Allowing a variety of reactions to occur at ambient temperatures and in solvent free conditions, ball milling presents a greener route for many chemical processes. Compared to the use of microwave and ultrasound as energy sources for chemical reactions, ball milling is not
