Figure 5

Ratio of measured capacitance after to before the dealloying step. The capacitance ratio as a function of the copper composition (at.%) removed in the dealloying step. Negative Cu removed indicates that Ni was selectively removed in the dealloying step rather than Cu. The dashed line indicates identical measured capacitances before and after dealloying.
