Shannon sampling based approach for the structural solution of nano‐objects by laboratory and synchrotron SAXS data

open access: yesJournal of Applied Crystallography, Volume 59, Issue 4, Page 1170-1183, August 2026.
We present a model‐independent approach based on the Shannon sampling theorem to retrieve key structural parameters of proteins and core–shell micelles directly from small‐angle X‐ray scattering (SAXS) profiles. By bypassing the pair distribution function, the method overcomes q‐truncation artifacts and provides reliable mass, size and aggregation ...

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 ...

Tetragonal distortion of the multiferroic compound α‐LiFe5O8 from first‐principles calculations

open access: yesJournal of Applied Crystallography, Volume 59, Issue 4, Page 1307-1318, August 2026.
First‐principles calculations suggest the tetragonal space group P43212 for the multiferroic compound α‐LiFe5O8, with a direct band gap smaller than that in its widely known cubic space group P4332. The tetragonal lattice distortion a > c is explained by relatively strong antiferromagnetic exchange interactions parallel to the c axis and by Fe–O–Fe ...

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 ...
