Global scientific exchange has been profoundly perturbed by the COVID-19 pandemic, altering user travel behaviours and accelerating the use of remote access. Combined with the advent of artificial intelligence (AI), these trends together can change how large-scale user scientific facilities are used by the community and managed by operators.

The phenomenon and definition of isostructurality are discussed. It deserves reconsideration regarding the aspects of symmetry, measure of similarity and formation of supramolecular interactions.

This commentary describes a novel method for serial electron diffraction data collection in electron crystallography, utilizing a scanning transmission electron microscope to rapidly obtain patterns with low radiation dose. This approach, demonstrated with zeolite samples, has the potential to provide highly automated and rapid structures from nanocrystalline materials.

Interoperability of scientific data within crystallography has been achieved to a high level by the adoption of standard exchange formats and protocols. Extending such interoperability across other disciplines is a goal of the International Science Council Committee CODATA, to which the IUCr has been a leading contributor. Our article combines a description of the importance of interoperability for addressing grand challenges with a desire to stimulate the crystallographic community to continue exploring this topic.

A deep-learning method is applied to separate the components of diffuse scattering from chemical short-range order and the molecular form factor. The method is validated against a large simulated dataset and further tested on a real example, resulting in output components of sufficient quality to use for quantitative analysis.

The most stable transtrans conformation of the di­ethyl ether molecule hinders its aggregation due to restricted access to the oxygen atom. This hindrance can be removed by conformational transformation under high pressure.

An implementation of scanning transmission electron microscopy serial electron diffraction (SerialED) through scripting is proposed. SerialED and continuous-rotation electron diffraction refinement results for the structure of zeolite Y are compared, and the structure of beam-sensitive ZSM-25 is solved by direct methods from electron diffraction data for the first time.

A method is described for determining the 3D structure of a sample from X-ray free-electron laser single-particle diffraction patterns by analyzing different orders of spatial correlations of diffraction intensities.

The alignment and self-assembly behavior of silica–nickel Janus particles in an external magnetic field were probed by ultra small-angle X-ray scattering. A theoretical framework is provided for the quantitative interpretation of the observed anisotropic scattering features.

Grazing-incidence total X-ray scattering allows for orientational pair distribution function analysis of indium oxide thin films with only a single measurement. Elucidation of information such as effects of film anisotropy on bond lengths in specific orientations relative to the substrate and determination of orientation in X-ray amorphous films is demonstrated.
