Nass et al. [IUCrJ (2016), 3, 180–191] have demonstrated that serial femtosecond crystallography (SFX) data collected at X-ray free-electron lasers (XFELs) can be successfully phased using only the weak anomalous scattering from the native S atoms.

High-pressure single-crystal neutron Laue diffraction yields data suitable for fully anisotropic structure refinement, allowing joint X-ray and neutron studies of exactly the same sample. Remarkably, data completeness is similar to ambient-pressure measurements, despite the presence of a pressure cell.

A systematic analysis of anomalous diffraction data obtained by serial femtosecond crystallography at an X-ray free-electron laser is presented and sulfur SAD phasing of SFX data from thaumatin microcrystals is demonstrated.

A 3:1 stoichiometric co-crystal of benzene and ethane has been structurally characterized at 90 K using synchrotron powder X-ray diffraction following in situ crystal growth at 130 K. The conditions under which the co-crystal forms identify it as a potential evaporite material on the surface of Saturn's moon Titan.

The application of X-ray diffraction topography in space materials science has promoted the acquisition of fundamental knowledge of space as a new technological environment. It has allowed a better understanding of the processes occurring during melt crystallization and the improvement of terrestrial methods of crystal growth for growing more homogeneous crystals.

Two dipolar biphenyls show significant 180° orientational disorder resulting in bipolar as-grown crystals. An added symmetrical biphenyl interferes with polarity formation and inverts the initial bipolar state.
