Abstract

On a charge: The experimental capacitance per cluster (C) as a function of charge state (z, see picture) confirms the quantized charging of "ligand-free" metal clusters in an ionic liquid. DFT calculations indicate a switch in orientation of the ionic shell around the clusters when the sign of the charge changes, and explain the maximum capacitance at zero charge.
