Seminar

Abstract

In recent years, electrochemical technologies have become increasingly important in
addressing global challenges such as sustainable energy production, corrosion prevention, and
advanced materials development. Achieving higher efficiency and longer material lifetimes
requires not only improved materials, but also a deeper understanding of how electrochemical
reactions occur. Traditional electrochemical methods, however, typically provide averaged
information over an entire surface, potentially masking localized activity and failure sites that
determine overall performance.
Scanning Electrochemical Cell Microscopy (SECCM) is a technique developed to overcome
this limitation by enabling spatially resolved electrochemical measurements. Using a
microscopic droplet of electrolyte as a movable reaction cell, SECCM allows localized
experiments to be performed point by point across a surface, generating functional maps of
activity, kinetics, and stability. This approach reveals inhomogeneities that remain inaccessible
to conventional measurements lacking spatial resolution and surface sensitivity. The key
concepts behind the technique and its capabilities will be introduced in an accessible way,
followed by an overview of recent developments and future directions. Together, these aspects
highlight how SECCM is expanding the way electrochemical processes are studied and
understood.

The seminar will be held in English.
