X-Ray sum frequency generation; direct imaging of ultrafast electron dynamics [PDF]
, 2018 X-ray diffraction from molecules in the ground state produces an image of their charge density, and time-resolved X-ray diffraction can thus monitor the motion of the nuclei.

Crystal structure of 3-bromo-2-hydroxybenzonitrile
Acta Crystallographica Section E: Crystallographic Communications, 2015 The crystal structure of the title compound, C7H4BrNO, has been determined, revealing a partial molecular packing disorder such that a 180° rotation of the molecule about the phenol C—O bond results in disorder of the bromine and nitrile groups.

The Limits of X-ray Diffraction Theory
Crystals, 2023 X-ray diffraction theory allows the interpretation of experiments to build a structural model that fits the collected data. As with any experimental science, the observations are subject to uncertainty through the instrument and user limitations ...

X-ray diffraction study of cadmium hydroxyapatite [PDF]
, 2005 Solid solutions of cadmium and calcium hydroxyapatite [Ca10−x Cdx (PO4)6 (OH)2 (0 ≤ x ≤ 10)] were synthesized by a wet process in a basic medium. The lattice dimensions of these compounds vary linearly with the atom percent cadmium.

Progress and Poverty—1965 Version [PDF]
, 1965 The first hard X-ray laser, the Linac Coherent Light Source (LCLS), produces 120 shots per second. Particles injected into the X-ray beam are hit randomly and in unknown orientations by the extremely intense X-ray pulses, where the femtosecond-duration X-
