Chemical reactions at solid‐liquid‐gas interfaces can be observed directly at the nanoscale by utilizing a novel in situ imaging technique named liquid cell transmission electron microscopy (LCTEM). In this work, etching of gold at a solid‐liquid‐gas interface is investigated in situ by LCTEM. A dedicated reaction mechanism involving the interaction between particle and nanobubble is proposed. Subsequent growth of gold nanoparticles is observed and modeled. More details can be found in article number 1901027 by Andreas Hutzler, Birk Fritsch, and co‐workers.
