    Dec 20, 2019· Mixing solid reactants in aball millis a promising means of avoiding the copious solvent waste associated with most chemical syntheses. Kubota et al. now report that adding a piezoelectric catalyst to the mix can promote bond formation through apparent electron transfer cycles (see the Perspective by Xia and Wang). Specifically, barium titanate activates aryl diazonium salts toward ...

    By contrast, attritionmillingrelies on a horizontal rotating vessel filled with a size-reduction solution. Treated to grinding media, the materials tend to be turned into free-flowing, spherical particles. This method, which includes theball mill, canreduce1,000 micron (20-mesh) particles of friable materials down to less than 1 micron.
