The proposed methodology requires no equivalent circuit analysis or data fitting and is equally applicable to the strong coupling (diffusion-mediated) or weak coupling electron-transfer regimes.10920-10926engArtigo10.1021/ac402378nWOS:000327360900042Acesso restrito04770459067332540000-0003-2827-0208
