Metal-organic Frameworks (IMAGE) University of Chicago Caption This simplified illustration depicts the triangular pyramidal structure of a metal-organic framework binding pocket designed to collect uranium atoms. The framework is displayed both before (left) and after binding with the atom, represented here as an orange sphere. Such MOFs show promise for extracting uranium from seawater.
