Femtosecond X-ray diffraction from two-dimensional protein crystals

X-ray diffraction patterns from two-dimensional (2-D) protein crystals obtained using femtosecond X-ray pulses from an X-ray free-electron laser (XFEL) are presented. To date, it has not been possible to acquire transmission X-ray diffraction patterns from individual 2-D protein crystals due to radiation damage. However, the intense and ultrafast pulses generated by an XFEL permit a new method ...

Fabrication of two-dimensional hard X-ray diffraction gratings

Hard X-ray grating interferometry has shown promising results in phase and scattering imaging, as well as in metrology applications. Recently, the technique has been extended to two dimensions, recording the full phase gradient vector and a directional scattering signal. Here, we present a process for fabricating the key optical elements required for this technique: phase and absorption grating...

X-ray diffraction from microtubules.

X-ray diffraction patterns from sperm-tail microtubules indicate that subunits with a 40 to 50 A packing diameter form filaments, alternately half-staggered, parallel to the tubule axis. A 12-or a 13-stranded structure fits best with the X-ray diagram. The strongest bonding is that between units within a longitudinal filament; the weaker lateral interactions are disrupted by drying. Microtubule...
