In electron microscopy the principle of reciprocity is often used to imply time reversal symmetry. While this is true for elastic scattering, its applicability to inelastic scattering is less well established. From the second law of thermodynamics, t...

Oxychalcogenides containing transition metal or p block cations have potential for thermoelectric, photocatalytic and magnetic applications but the synthetic pathways to these quaternary phases are not fully understood. This presents a challenge to t... Read More about La₂O₂MQ₂ phases: stability and synthetic challenges.

Three‐dimensional electron diffraction (3D‐ED) is a powerful technique for crystallographic characterization of nanometre‐sized crystals that are too small for X‐ray diffraction. For accurate crystal structure refinement, however, it is important tha... Read More about Modelling dynamical 3D electron diffraction intensities. I. A scattering cluster algorithm.

The strong interaction of high‐energy electrons with a crystal results in both dynamical elastic scattering and inelastic events, particularly phonon and plasmon excitation, which have relatively large cross sections. For accurate crystal structure r... Read More about Modelling dynamical 3D electron diffraction intensities. II. The role of inelastic scattering.
