We observe chemical reactions and structural changes in natural and artificial systems while they take place. We probe advanced 2D materials, metal complexes and metalloproteins, to understand their transformations and how they function. Ultrafast pulses from X-ray lasers and lab sources give us the high-speed X-ray vision to watch the inner workings of electrons, atoms, and molecules in real time.
