The cover picture shows the
transfer of uranium peroxide capsule-like clusters from water (blue) to organic solvent (purple). Each capsule contains 20–35 uranium atoms, and therefore the phase
transfer that is depicted here occurs with high efficiency. This new uranium separation process could be employed in the various steps of the
nuclear fuel cycle, which include mining, fuel reprocessing, and separation of wastes. Details are discussed in the article by M. Nyman et al. on page 39 ff (DOI:
10.1002/ejic.201601219). For more on the story behind the cover research, see the Cover Profile (DOI:
