Figure 5: Imbibition kinetics versus cyclohexane.

(a) Mass, m, versus time, t, for experiments at various constant values of the electrode potential, as indicated by labels. Solid lines are straight lines of best fit. (b) Response of imbibition to step potentials. Symbols and left ordinate: mass, m, evolution with time, t, during imbibition of 1 M KOH into cyclohexane-saturated nanoporous gold. The potential was stepped as indicated by the dashed line and right ordinate. The black solid line is a guide to the eye.
