Back-Cover-Page: Nanoporous gold, prepared by electrochemical dissolution of Ag from commercial white gold leaf, was investigated by HAADF-STEM tomography. The picture shows a surface-rendering of a fully connected network structure composed of single-crystalline gold ligaments and pores reconstructed in three dimensions. The study advertises the power of electron tomography as an emerging tool for elucidating the three-dimensional microstructure of materials with a nanoscale resolution. Further Information can be found in the paper by Rösner et al. on page 535.
