Big Reaction: Nanoscale etching a penny

My lab is located at the Lawrence Berkeley National Laboratory (LBL), just up the hill from UC Berkeley. The lab is home to a wide range of cool research and cutting edge technology. The demo shown here, produced by the Molecular Foundry at LBL, showcases two different techniques for creating nanoscale features.
