Small, fast and high contrast: Annular dark field dynamic transmission electron microscopy (ADF‐DTEM) can produce high‐contrast images of catalyst nanoparticles with 15 ns temporal resolution (see picture). The contrast improvement provided by this technique enables imaging studies on the dynamics of heterogeneous catalysts at unprecedented spatial and temporal resolution.
