Observing the movements of single atoms at the surface of a solid is one of the ultimate goals of microscopy. On page 1971 , Günter Möbus and co‐workers use atomic‐resolution aberration‐corrected transmission electron microscopy to monitor the inherent instability of CeO 2 (100) surface facets of a nanoparticle. The image series shows a hopping sequence of Ce atoms. Catalysis and other surfaceactivity‐related application fields of ceria will benefit from this study.
