Grinding enhances the magnetic hardness of …

The investigation of influences of the grinding method on the crystal samples of compound 1 reveals that the coercivity increases from ∼2.5 Oe to 44.0 Oe upon a grinding treatment for 180 minutes. The results demonstrate that compound 1 can vary from a soft magnet to a hard magnet simply by manually grinding the crystal samples to the nanoscale.

Mechanochemical synthesis is staging a comeback, however, largely thanks to the burgeoning interest in sustainable chemistry. Most mechanochemistry techniques use little or no solvent. ''Solvent is the largest mass in a [traditional] chemical reaction and removing that mass inherently makes things greener,'' explains James Mack, a chemistry professor at the University of Cincinnati in the US.
