Surface-optimized core–shell nanocomposites (Fe3O4@MnxFeyO4) for ultra-high uranium sorption and low-field separation in water

In this work, we systematically design and synthesize manganese ferrite coated superparamagnetic magnetite nanocrystals, with oleylphosphate bilayer surface coatings (Fe₃O₄@Mn_xFe_yO₄@OP), for ultra high capacity uranium sorption and low-field magnetic-based separation in water.
