A further development in atomic force microscopy now makes it possible to simultaneously image the height profile of nanometer-fine structures as well as the electric current and the frictional force at solid-liquid interfaces. A team from the Helmholtz-Zentrum Berlin (HZB) and the Fritz Haber Institute (FHI) of the Max Planck Society has succeeded in analyzing electrocatalytically active materials and gaining insights that will help optimize catalysts. The method is also potentially suitable for studying processes on battery electrodes, in photocatalysis or on active biomaterials.
