Schematic of the SECCM setup and imaging modes. (A) Experimental setup (bottom) and resulting measurement data (top). Simultaneous topography and activity mapping consisting of 7200 individual points. Reproduced from Wahab, O. J.; Kang, M.; Meloni, G. N.; Daviddi, E.; Unwin, P. R. Anal. Chem.2022, 94 (11), 4729–4736 (ref (223)) under CC BY 4.0 license. (B) Operation modes showing the single- and double-barrel SECCM configuration (top) and the hopping and constant-distance modes (bottom). (C) Model measurement snippets, demonstrating various electrochemical techniques that can be applied in a localized manner using the SECCM platform.
