Unlocking Neptunium(IV) Aqueous Chemistry via Polyoxometalate-Mediated Reduction and Stabilization Open
Distinct from the rest of the periodic table, including its actinide neighbors, neptunium exhibits truly unique chemistry as its speciation and chemical behavior are dominated by the neptunyl(V) ion, i.e., NpO2+. Here, we describe the spon…
