Imaging of chirality domains: Resonant circularly polarized X-ray diffraction distinguishes crystalline enantiomers (see picture). Control of the penetration depth and microfocusing of X-rays leads to a new visualization technique of the three-dimensional chirality-domain morphology, providing support to the increasing demand for the improvement of inorganic chiral crystal engineering.
