In article number 1703615 , Dale L. Huber and co‐workers form nanoparticles directly from bulk metal using ultrasound. The method occurs in water and is applicable to a number of different metals and alloys. Any bulk metal form factor can be used, as long as there is a sufficiently large planar surface to induce asymmetric cavitation bubble collapse. The method is then applied to the recovery of gold from a cellular SIM card in the form of gold nanoparticles.
