Thermal expansion of FeWO4 (ferberite) and FeWO4:Fe2WO6 (7:1): a comparative X‐ray and neutron diffraction study

open access: yesJournal of Applied Crystallography, Volume 59, Issue 4, Page 1238-1246, August 2026.
Temperature‐dependent single‐crystal X‐ray, powder X‐ray and neutron diffraction measurements reveal the thermal expansion behavior of FeWO4 from 2 to 1123 K. Significant differences between natural ferberite and a FeWO4:Fe2WO6 composite highlight the influence of multiphase and microstructural effects on derived thermoelastic parameters.The thermal ...

Improving polarized neutron reflectometry experiments on soft‐matter samples: optimization of the solid substrate structure

open access: yesJournal of Applied Crystallography, Volume 59, Issue 4, Page 1192-1199, August 2026.
We demonstrate a Fisher‐information‐based strategy for optimizing the solid substrate structure in polarized neutron reflectometry experiments on soft‐matter samples. The approach identifies magnetic reference layer designs that improve experimentally accessible information and provides a general framework for more efficient reflectometry experiment ...

Integrated analysis with iCM‐SANS, SAXS and MD simulations for dynamics of multi‐domain proteins

open access: yesJournal of Applied Crystallography, Volume 59, Issue 4, Page 1270-1281, August 2026.
Segmental deuteration, combined with inverse contrast‐matching small‐angle neutron scattering (iCM‐SANS) and small‐angle X‐ray scattering (SAXS), provides structural constraints that improve discrimination of conformation ensembles of multi‐domain proteins derived from molecular dynamics (MD) simulations.Multi‐domain proteins (MDPs) adopt diverse ...

High‐pressure and high‐temperature polymorphism of Na2CO3 up to 10 GPa

open access: yesActa Crystallographica Section B, Volume 82, Issue 4, Page 410-415, August 2026.
Two new high‐pressure phases, ϵ and ϵ‐II, observed during in situ experiments, complete the high‐pressure phase diagram of Na2CO3 and show that both the incommensurate γ phase and the ϵ phase are stable over a wider pressure–temperature range under mantle‐relevant conditions.We report two new high‐pressure polymorphs of sodium carbonate, ϵ and ϵ‐II ...
