“…115 One more thing needs to be considered about the nonlinear relationship between the applied potential and the measured current, which means there is no guarantee that the current will respond to the applied sinusoidal potential. 44 Aside from corrosion research, the MCC technique has also been successfully applied to investigate other interesting aspects, such as electrodeposition of pure metal (e.g., Cu 116−118 and Ni 119,120 ), surface modification, 121 electrochemical machining, 122−125 electrocatalyst materials screening, 70,75,126−128 localized anodizing, 129,130 and thin-film properties characterization. 53,131,132 Furthermore, a multiparallel microcell 120 and devices with an automatic test function 70,131,133 have been developed to achieve high-throughput localized electrochemical characterization, opening a new paradigm of electrochemical analysis.…”
