Gold Nanocrystals Direct observation for growth and etching of colloidal nanocrystals will likely benefit rational design of specific nanoparticles. In this study, the graphene liquid cell electron microscopy not only provides the environment for growth and oxidative etching of colloidal gold nanocrystals, but also proves whole process from growth to etching. Direct observation demonstrates different kinetics at each step. More details can be found in article number 1800949 by Sang Yun Kim, Jong Min Yuk, and co‐workers.
