Chemistry by color: The first dynamic study using X-ray diffraction computed tomography investigates the evolving chemistry and structural changes during the preparation of a millimeter-sized industrial hydrogenation catalyst body (see picture; time evolves from left to right, and different colors represent different phases). The method has potential for chemical imaging of materials within bulk objects undergoing physicochemical changes.
