    Research: Electron Microscopy

    Electron microscopy is and advanced tool for investigating the structure of materials. In electrocatalysis, this technique is used not only to study the catalyst structure at the level of atoms, but also to follow the structural changes of the materials caused by electrocatalytic activity.
