Cryo-coherent diffractive imaging of biological samples with X-ray free-electron lasers

Recent developments in the imaging of biological samples using the X-ray free-electron laser at the SACLA facility are highlighted.

Cryogenic coherent X-ray diffraction imaging of biological samples at SACLA: a correlative approach with cryo-electron and light microscopy

Cryogenic coherent X-ray diffraction imaging can be used for structural analysis of unstained, non-crystalline, whole biological samples such as cells and cell organelles. This article reports on current and future applications of cryo-coherent diffraction imaging with the X-ray free-electron laser (XFEL) at the Japanese XFEL facility, SACLA, and demonstrates the merit of a correlative approach with cryo-electron and light microscopy.

Bragg–von Laue diffraction generalized to twisted X-rays

An X-ray method of structure determination for some important noncrystalline structures is proposed.

On the possibility of using X-ray Compton scattering to study magnetoelectrical properties of crystals

The possibility of using X-ray Compton scattering to reveal antisymmetric components of the electron momentum density, as a fingerprint of magnetoelectric sample properties, is investigated experimentally and theoretically by studying the polar ferromagnet GaFeO₃.

Dynamic quantum crystallography: lattice-dynamical models refined against diffraction data. I. Theory

A new refinement approach based on lattice dynamics derived from periodic ab initio calculations is described. The approach is tested on high-resolution diffraction data for urea.

Three-dimensional propagation in near-field tomographic X-ray phase retrieval

An extension of phase retrieval algorithms for near-field X-ray (propagation) imaging to three dimensions is presented, enhancing the quality of the reconstruction by exploiting previously unused three-dimensional consistency constraints.

Anion order in perovskites: a group-theoretical analysis

All aristotypes of anion superstructures in the perovskite family of crystals are established. The calculated structures of some anion superstructures are reported.

Ab initio structure determination of nanocrystals of organic pharmaceutical compounds by electron diffraction at room temperature using a Timepix quantum area direct electron detector

A specialized quantum area detector for electron diffraction studies makes it possible to solve the structure of small organic compound nanocrystals in non-cryo conditions by direct methods.

Wiener index on rows of unit cells of the face-centred cubic lattice

The Wiener index of various graphs represents a structure compactness measure of the graph. The face-centred cubic lattice is one of the most usual crystal lattices; in this paper, the Wiener index of its graph is computed having unit cells in a row.

Analysis of multicrystal pump–probe data sets. II. Scaling of ratio data sets

The crucial need for scaling of multicrystal data sets and for the correction of the light-induced response anisotropy inside a data set in time-resolved pump–probe crystallography is discussed. An application of methods developed is presented.
