Slice by slice atom probe tomography data from a Au@Ag core–shell nanoparticle reveals the arrangement of the atoms throughout the particle. The Cover Picture shows the distribution of Au (yellow) and Ag (gray) atoms within a 15 nm nanoparticle, determined with near‐atomic resolution by T. Maschmeyer and co‐workers in their Communication on page 11190 ff. The elements are not evenly distributed across the surface, a result of surface morphology and of residues from the particle synthesis.
