The ab-plane optical conductivity of the Weyl semimetal TaP is calculated from the band structure and compared to the experimental data. The overall agreement between theory and experiment is found to be best when the Fermi level is slightly (20 to 6

The present laboratory diffraction contrast tomography suffers from poor spatial resolution – only grains larger than 40 µm can be reliably imaged. In this work, it is shown how this serious limitation can be lifted and the spatial resolution impr

Ubiquitous defects in polycrystalline powders and single crystals affect the pathways of polymorphic solid-to-solid phase transitions. Dependent on the density of crystal defects, the phase transition mechanism can be dominated by either the cooperat

The styryl and ester substituents are displaced to opposite sides of the plane through the pyridine ring while the acetyl group is rotated well out of that plane. In the crystal, inversion-related C—H⋯O hydrogen bonds form chains extending parall

Serial femtosecond crystallography is coming of age. Therefore, it is time to consider best practices and appropriate standards.
Serial femtosecond crystallography (SFX) at X-ray free-electron lasers (XFELs) is a novel tool in structural biology

The mechanism of a solid–solid phase transition in an RNA crystal is presented.
Solid–solid phase transitions (SSPTs) occur between distinguishable crystalline forms. Because of their importance in application and theory in materials science
