Effect of ball milling parameters on the particle size in
Abstract A model describing the mechanical comminution (ball milling) of crystals to nanocrystalline powders is proposed. It is shown that a fraction of the energy deposited in the processed material is spent for the creation of microstresses ɛ which slows down the comminution process.

Anti‐aldol products with up to >99 enantiomeric excess (ee) have been obtained by proline catalysis in excellent yields under experimentally simple solvent‐free conditions.Efficient mixing of all the components is accomplished by applying a mechanochemical technique (ball milling). The catalysis is air and moisture tolerant and can be performed with non‐purified starting materials.
