Jujube (Ziziphus jujuba Mill.) has long been used for human consumption and medicinal purposes in China. It is recommended for some diseases in which radical species are produced as a result of oxidative stress. However, the systematic study on the antioxidant capacities of various tissues of jujube is still lacking.

The difference in speeds between balls and jars produces an interaction between frictional and impact forces, which releases high dynamic energies. The interplay between these forces produces the high and …

Ball mills can reduce particles to nano sizes, the process is very important in creating powders used in hi-tech industries (e.g. alumina). Ball mills are slow compared to other methods of grinding, it could take hours, for example, to grind all the particles in a clay to minus 200 mesh. Industrial mills seeking nano-sizes might run 24 hours or ...
