A multiscale approach has been used to link metal‐ion coordination with nanoscale structure to reveal the free‐energy balance that drives the phase transfer of neutral metal salts. This study gives structural insight into the intricate relationship between the hard metal‐ion complexation interactions and the soft long‐range interactions between aggregates. The cover art (by Sana Sandler, Argonne National Laboratory) depicts a malonamide amphiphile, which has been used to extract Eu(NO 3 ) 3 from water into oil, through the water–oil interface. Such metal separation techniques are important in the efficient reprocessing of nuclear waste and the refining of rare‐earth elements. For more details, see the Full Paper by R. J. Ellis, L. Berthon, P. Guilbaud et al. on page 12796 ff.
