The paper shows overall quality of Cr/Be X-ray multilayer mirrors and gives estimated values of roughness and material intermixing separately.

An optimization procedure of an aerodynamic lens injector with variable geometry is presented using our previously developed numerical-simulation framework. The simulation results are validated by performing experiments on gold and sucrose nanoparticles. This work is envisioned to be an important step toward high-resolution single-particle imaging enabled by high-density beams of small nanoparticles, which are created by injectors optimized for size and material of the nanoparticles as well as for the experimental conditions.

An approach to optimization of the measurement configuration in X-ray diffraction by maximization of Fisher information is proposed. The developed technique is applied to high-resolution X-ray diffraction measurements and microstructure analysis.

The single-crystal growth of Gd₄Ga₂O₉ with the optical floating zone technique is reported. Abundant structural information through powder X-ray diffraction combined with Rietveld refinement has been obtained. Magnetic susceptibility and heat capacity measurements suggest an antiferromagnetic phase transition and strong magnetic frustration characteristics.

Two examples of twinning, by metric and reticular merohedry, in uranyl-oxide minerals demonstrate the care that must be taken during structural studies of (not only) such complex materials. This contribution also demonstrates the possibilities of the Jana2020 program in revealing twinning from subsequent refinement.

For aqueous solutions in quasi-elastic neutron scattering (QENS) studies, Al alloys with higher Al content, boehmite coating, reduced surface area and reduced concentrations of dissolved oxygen tended to be resistant to corrosion. QENS measurements of the empty sample cells revealed that (1) the profile of the cell fabricated with copper-free Al alloy showed a minor scattering vector dependence and (2) reducing the real surface area of the Al surface effectively suppresses its scattering intensity.

A method is presented for subtracting the pairwise correlations of a pressure-transmitting medium from neutron pair distribution functions obtained under hydro­static compression, and applied to Ni, MgO and α-quartz.

The structure of copper tellurite glasses has been investigated by neutron diffraction.

It is pointed out that ab initio indexing of electron backscatter diffraction (EBSD) patterns belongs to the field of indexing single-crystal diffraction data, and the problem can be solved on the same principles as indexing of patterns of other types. It is shown that EBSD-based data can be indexed by programs designed for X-ray data.

The linear-algebraic approach to finding cooperative rigid-unit modes in interconnected networks has been greatly improved.

The electro-optical and gyration parameters of a lead germanate ferroelectric single crystal in the direction perpendicular to the optical axis have been investigated by a high-accuracy polarimetric technique.

ISOTILT is a user-friendly web-based software package for discovering the cooperative rigid-unit modes in materials whose structures contain interconnected networks of rigid units.

Peak profile functions in powder diffraction are presented with the support of Mathematica scripts, easily usable by interested readers, to explore the effect of different instrumental and microstructural parameters. Subsequent articles will illustrate the most common aberrations to the measured patterns and then total scattering methods.

A method is presented for the self-consistent description of the variations of unit-cell parameters of crystals with pressure and temperature.

This article describes recent developments on the SWING beamline for biological small-angle X-ray scattering (BioSAXS) experiments.
