SECCM
Scanning electrochemical cell microscopy (SECCM) is a scanning probe technique which shrinks the conventional electrochemical cell down to the size of a droplet at the end of a capillary. The droplet is lowered onto many different points on the surface where electrochemical measurements such as linear sweep voltammetry (LSV) or cyclic voltammetry (CV) can be performed.
Our group works to develop SECCM such as through coating the surface in oil to preserve it over long experiment times or modelling the effects of using a high voltage scan rate when performing fast LSV or CV measurements. We primarily use SECCM to study the corrosion of metal alloys such as aluminium and stainless steel. For recent publications from our group on the subject see below:
