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.
A comparison of the different conformations adopted by C-glycosylated mannosides in FimH crystal structures is reported together with the investigation of new interactions.
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.
The change in the crystal structure of polymer-grafted nanoparticles during uniaxial stretching was investigated by simultaneous ultra-small-angle X-ray scattering and stress–strain measurement.
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.
