ball grinding mechanochemical

Ball-free mechanochemistry: in situ real-time monitoring. Mechanochemical techniques (e.g. planetary and vibratory ball milling, grinding, etc.) are a useful method for multi-component, one-pot syntheses of a wide range of compounds and materials. 1 The mechanosynthesis of multi-component organic materials is believed to proceed via fluid-like intermediate phases.
