Grazing‐incidence scattering surveyed: towards reference methods for alignment and calibration

open access: yesJournal of Applied Crystallography, Volume 59, Issue 4, Page 1247-1253, August 2026.
With the recent gain in popularity of grazing‐incidence instruments, harmonization is needed to establish intercomparability. This review of existing instruments and methods highlights the diversity of approaches in the community and is a first step towards reference methods.Grazing‐incidence small‐angle scattering (GISAS) is a relatively young ...

Measurements and scaling of X‐ray total scattering from single crystals

open access: yesJournal of Applied Crystallography, Volume 59, Issue 4, Page 1224-1237, August 2026.
A measurement protocol and data reduction workflow are presented for obtaining single‐crystal X‐ray total‐scattering datasets on an absolute scale, capturing both Bragg and diffuse intensities from the same dataset. The study demonstrates consistency between scale factors derived from Bragg refinements and from spherical integration of the total ...

Gas‐controlled capillary spinner for time‐resolved powder X‐ray diffraction under dynamic conditions

open access: yesJournal of Applied Crystallography, Volume 59, Issue 4, Page 1359-1363, August 2026.
The newly developed gas‐controlled capillary spinner enables continuous high‐speed sample rotation during in situ powder X‐ray diffraction under dynamic gas conditions. By improving the uniformity of the diffraction intensity, this system enables reliable millisecond time‐resolved structural analysis for operando studies.A gas‐controlled capillary ...

Deciphering unusually large modulations in two related organic hydroxy channel structures

open access: yesActa Crystallographica Section B, Volume 82, Issue 4, Page 375-390, August 2026.
Two related organic hydroxy‐channel compounds are shown to have unusually large structural modulations.The incommensurately modulated structures of two related organic hydroxy‐channel compounds [(R)‐1‐(1,3‐dihydroxypropan‐2‐yl)‐3‐(octan‐2‐yl)urea, 1; 1‐(1,3‐dihydroxypropan‐2‐yl)‐3‐octylurea, 2] have been determined and compared to the structure of a ...

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 ...

Mapping structure–property relationships in a 6‐oxo‐verdazyl radical by variable pressure crystallography and density functional theory

open access: yesActa Crystallographica Section B, Volume 82, Issue 4, Page 416-432, August 2026.
For the first time, the structural response to pressure of a verdazyl radical crystal has been studied. Computational modelling revealed changes in electronic and magnetic properties as a result of a structural phase transition.The response of the 1,5‐tolyl‐3‐phenyl‐6‐oxo‐verdazyl radical (pTolOV) to pressure in the crystalline state has been ...

Coupled intra‐ and inter‐tunnel short‐range order in hollandites: a case study of mannardite Ba[(Ti4+)6(V3+)2]O16

open access: yesActa Crystallographica Section B, Volume 82, Issue 4, Page 439-446, August 2026.
Single‐crystal X‐ray diffuse scattering combined with Monte Carlo simulations and 3D‐ΔPDF analysis reveals complex short‐range order in mannardite, involving coupled Ba–Ba interactions within and between tunnels and framework relaxation.Mannardite, Ba[(Ti4+)6(V3+)2]O16, a mineral of the hollandite supergroup, is characterized by a tunnel structure ...
