DOI: 10.1007/s10967-017-5659-2
Abstract: The effective capacitance of an aqueous solution containing the nanoscale uranyl peroxide cage cluster U60 (Li48K12[UO2(O2)(OH)]60(H2O)n, n ≈ 310) was measured using cyclic voltammetry. The potential window (50–90 mV) for the measurements precluded changes to the oxidation state… read more here.
