Powder diffraction is a widespread technique found in academic, forensic, industrial research and quality-control laboratories the world over. The recent article by Kabova et al. [(2025), Acta Cryst. C81, 559–569] provides step-by-step guidance on how to proceed and the software the authors use, from sample preparation and the powder diffraction measurement itself, to the verification of the final structure.

We describe an efficient algorithm to compute the bridge length estimating the size of a complete isoset invariant, which classifies all periodic point sets under Euclidean motion.

Mechanically flexible single crystals are emerging as a useful class of materials due to their unique combination of crystallinity and molecular-scale responses to applied mechanical stress. In this t...

Single crystal diffraction analysis remains the gold standard for the three-dimensional atomic structure characterization of framework materials such as metal–organic frameworks, covalent organic fram...
