Chemical crystallography by serial femtosecond X-ray diffraction

WebApr 19, 2016 · Serial femtosecond crystallography (SFX) uses an X-ray free-electron laser to extract diffraction data from crystals not amenable to conventional X-ray light sources owing to their small size or radiation sensitivity. However, a limitation of SFX is the high variability of the diffraction images that are obtained. As a result, it is often difficult to … WebGeometric Crystallography - Feb 06 2024 In the last decade mathematical crystallography has found increasing interest.

Miller indices form a notation system in crystallography for lattice planes in crystal (Bravais) lattices. In particular, a family of lattice planes of a given (direct) Bravais lattice is determined by three integers h, k, and ℓ, the Miller indices. They are written (hkℓ), and denote the family of (parallel) lattice planes (of the given Bravais lattice) o… WebMar 25, 2024 · Indexed images refer to images in which the input unit cell parameter and information about the crystal system match. The indexing rate (ratio) is a statistic obtained by dividing the number of indexed images that match the input crystal information by the total number of hit images.
