A survey of the theory of diffraction symmetry involving anomalous scattering is given, and conditions for the occurrence of Bijvoet differences are discussed in detail. Some applications of Friedel-law violation, especially those to the determination of the space group and various kinds of Fourier techniques, are described.

We report enantiopure crystal growth and chiral helimagnetic ordering in chiral inorganic compounds CsCuCl3 with a chiral space group of right-handed P6122 or left-handed P6522. Our 2-step crystallization process makes it possible to grow centimeter sized enantiopure single crystals. Polarized neutron diffraction experiments probed that crystallographic chirality of CsCuCl3 strongly combined with helimagnetic chirality via Dzyalloshinskii-Moriya interaction.

We have prepared various ionic liquids containing cationic organometallic complexes, which exhibit intriguing physical properties and chemical reactivities. This review describes molecular design, preparation, and crystal structures of organometallic ionic liquids and related materials. Two topics are discussed, in which X-ray crystallography played an important role: magnetic-field effects on the crystallization of ferrocenium ionic liquids, and odd-even effects on the melting phenomenon of cobaltocenium ionic liquids.

Future of structural life science will continue to rely on crystallography using X-ray and electron beams. Multi-modal, multi spatio-temporal scale imaging will be the key to understanding complex biological phenomena at both fundamental biology and translational biomedical or industrial applications. This transformation is influencing the way structural and functional studies are carried out around the globe, and large insfrastructure facilities and institutions are developing new modus operandi to enable biology and medical communities accessing vast and diverse range of technologies, including X-ray, electron, photon, and neutron sources, and AI/ML.

I will describe the future direction of electron crystallography, by focusing on how electron beams contribute uniquely for atomic structure determinations. Both for electron diffraction and microscopy, the key lies on how we make the best use of dynamical scattering effects, which are significant for electrons compared with other probes including X-ray.

Current research in structural biology has advanced our insights much more than we expected 20 years ago. X-ray free-electron lasers and cryo-electron microscopy are technologies that have brought unprecedented achievements to researchers acquiring structural aspects of protein molecules at a higher level. This paper overviews current research in photosynthetic membrane proteins by utilizing these technologies and summarizes structural biology demands now encountering.

Recently, 2D detectors, such as IP (imaging plate) or CCD (chargecoupled device), become popular in single crystal data acquisition. As a practical guide, basic information is discussed on diffraction geometry and data processing of 2D detectors, in comparison with those of four-circle diffractometers. Main topics are a typical flow in data collection, indexing, evaluation of spot positions, data collection strategy, evaluation of integrated intensities, Lorentz factor, and determination of precise cell parameters.

TransLesion Synthesis (TLS) is a DNA damage tolerance mechanism that allows continued DNA synthesis, even in the presence of damaged DNA templates. In response to DNA damage, TLS polymerases are recruited to replication forks via interactions with ubiquitinated Proliferating Cell Nuclear Antigen (PCNA) involving PCNA-interacting protein box (PIP-box) and ubiquitin-binding domains (UBDs). We now report the first crystal structures of human PCNA in complex with three TLS polymerase peptides containing the non-canonical PIP-box. TLS polymerases interact with PCNA in different ways, both from one another and from canonical PIP-box peptides. Furthermore, we discuss these TLS polymerases interact with ubiquitinated PCNA.

Cothordoluminescence (CL) detection system was built up for a transmission electron microscope with scanning units, which enable us to take high-resolution CL images of crystal defects together with crystallographic information. Luminescence or non-luminescence centers localized at dislocations in III-V compound semiconductors, diamond and magnesium oxide were observed using this system. Their natures were studied through the analyses of the TEM and monochromatic CL images and spectral information of the CL light.

Many kinds of complicated crystal structures have appeared in the transition metal sulfide system. Simulation by the matrix method could explain the diffuse scattering observed in nonstoichiometric titanium sulfides with stacking faults, in Ti1.42S2 with short-range order of Ti vacancies, and in some channel-type composite crystals such as Ba0.7Cr2S3.7 with two-directional disorder of positions of filling columns. Crystal structures of incommensurate layered composite crystal (PbS) 1.12VS2, columnar composite crystals Ba10/9Fe2S4 and Ba9/8Fe2S4, and incommensurate columnar composite crystals SrxTiS3 (x=1.1-1.2) were successfully analyzed based on the superspace group approach.

A procedure for refining structural parameters and charge densities using convergent-beam electron diffraction (CBED) is described. The procedure is based on the nonlinear least-squares fitting between full dynamical calculations and energy-filtered intensities of two-dimensional higher-order Laue-zone (HOLZ) and zeroth-order Laue-zone (ZOLZ) CBED patterns.
