Single-crystal neutron structure analysis is a powerful technique to observe the position of hydrogen atoms in crystals with high accuracy and reliability because of its high sensitivity to hydrogen atoms. In Japan, the development of single-crystal neutron diffractometers for structure analysis has progressed since the 1990s at the JRR-3 research reactor. Subsequently, the construction of J-PARC MLF, a high intense spallation neutron source, started in the 2000s. The author has developed single-crystal neutron diffractometers at JRR-3 and MLF to make the single-crystal neutron structure analysis of organic and organometallic molecular crystals possible. In addition, the author has also been conducting research based on the reliable observation of hydrogen atoms in molecular crystals. This paper will review the recent development of single-crystal neutron diffractometers and studies in which hydrogen atoms play a crucial role.

The combination of small-angle X-ray solution scattering (SAXS) experiments and molecular dynamics (MD) simulations is now becoming a powerful tool to study protein dynamics in solution at an atomic resolution. We have developed a method called MD-SAXS, in which this combination is used with explicit evaluation of X-ray scattering from water molecules hydrating protein molecules. This method offers a link between low-resolution structural information from SAXS and the three-dimensional high-resolution structure. The study using MD-SAXS method revealed the importance of intrinsic dynamics of DNA-binding protein EcoO109I in its function.

Since the first crystal structure determination of protein by J. C. Kendrew in 1959, protein crystallography has been playing the leading role in the structural biology by various technology developments. Especially the utilization of synchrotron radiation from the 1990s brought innovative progress in this field on the data quality and the phasing method and had expanded the sample targets including membrane proteins and supra-molecular complexes. Here we will describe the outline and the future prospects of the protein crystallography from the role of synchrotron radiation and SPring-8.

Effective from 2021B, CryoTEM will be offered in addition to SPring-8 public beamlines for protein crystallography and BioSAXS beamlines. Two CryoTEMs, EM01CT(JEOL CRYO ARM 300), and EM02CT(JEOL CRYO ARM 200)are provided as auxiliary instruments for evaluating the properties of samples for crystallization, such as monodispersity and structural heterogeneity.

Described briefly are the present status of the experimental apparatus installed at the topography station and some user experimental results. At this station, it is possible to do the real time observation using VTR recording of topographic images of crystals either by direct method (saticon TV) or by indirect method (fluorescent film+TV) . Spot indexing of the Laue pattern and quick setting of the specimen orientation by computer has been developed. Many users have done various experiments since 1982 under various environmental conditions using white synchrotron radiation from normal bending magnet (BL-15) and wiggler magnet (BL-14) . Some examples of dynamic observations of the crystal imperfection, melting or solidification phenomenon, phase transition, and wall motion of the magnetic domain are shown.

A new method, called the direct derivation(DD) method, for quantitative phase analysis(QPA) can derive weight fractions of individual crystalline phases from sets of observed intensities and chemical composition data. The Patterson function plays an important role in replacing the sum of squared structure factors, calculated in the Rietveld method, with the sum of squared numbers of electrons belonging to the atoms in the chemical formula unit. Therefore, the DD method can conduct QPA of Rietveld equivalent without referencing to structure parameters. It can be applied to QPA of mixtures containing known structure, unknown structure, and high and low crystalline materials.
