Single-crystal x-ray diffraction structures of covalent organic frameworks
Covalent organic frameworks writ large Covalent organic framework (COF) materials have been difficult to characterize structurally and to exploit because they tend to form powders or amorphous materials. Ma et al.

Diffractive X-Ray Telescopes [PDF]
Diffractive X-ray telescopes using zone plates, phase Fresnel lenses, or related optical elements have the potential to provide astronomers with true imaging capability with resolution several orders of magnitude better than available in any other waveband.

This study presents recent developments and applications of ultrafast X-ray diffraction. These include optical pump/X-ray probe experiments for performing ultrafast X-ray spectroscopy, time-resolved X-ray diffraction for the investigation of electronically induced solid-liquid phase transformations in semiconductors, and time-resolved X-ray diffraction

Subpicosecond X-ray diffraction
With the advent of ultrashort (subpicosecond) high-power lasers it is now possible to create intense bursts of X-rays with subpicosecond durations. An analysis of the temporal response of diffraction of such X-rays by crystals in both the dynamical and kinematic regime is presented. It is also shown that under certain conditions the temporal resolution
