Atomic resolution tomography of a Au@Ag nanorod heterostructure. (a) Three orthogonal slices through the reconstruction show the core–shell structure of the nanorod. The atomic lattice can be resolved in all three slices. (b, c) Detailed view of the slices through the reconstruction perpendicular to and parallel to the major axis of the nanorod.37 Copyright 2013, American Chemistry Society.
