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:
