Accepted 11 February 2021

New perspectives in macromolecular powder diffraction using single-photon-counting strip detectors: high-resolution structure of the pharmaceutical peptide octreotide


Accepted 9 February 2021

Crystal symmetry for incommensurate helical and cycloidal modulations

A classification of the symmetry of magnetic modulations is presented. Helical magnetic ordering is possible only in magnetic superspace groups with proper rotations only, i.e. from classes 1, 2, 222, 4, 422, 3, 32, 6 and 622. Cycloidal modulations are possible in groups from crystal classes 1, 2, m and mm2.

Accepted 28 January 2021

X-ray dynamical diffraction Talbot effect behind a crystal in free space

The dynamical diffraction Talbot effect behind a crystal in free space is considered. The theoretical predictions of the effect are confirmed by numerical calculations.

Accepted 7 December 2020

Symmetry relations in wurtzite nitrides and oxide nitrides and the curious case of Pmc21

Binary and multinary nitrides in a wurtzitic arrangement are very interesting semiconductor materials. The group–subgroup relationship between the different structural types is established.
