This work shows that combining helical acquisition mode with synchrotron radiation propagation-based imaging computed tomography is a powerful tool for tissue engineering applications with image qualities of high contrast, low noise level and, most importantly, fewer ring artifacts.

The structures of apo and holo mutants of alginate lyase A1-III revealed a large open/closed conformational change of lid loop. The closed lid loop is involved both in the binding of substrate and catalysis of the enzyme.

An automatic 3D image registration method is implemented for correcting unanticipated sample deformation during nano-resolution spectro-tomography experiments. This method significantly improves the quality of the spatially resolved XANES spectra, which fingerprints the local chemistry.

Site-specific X-ray triggered photo-oxidation combined with temperature-controlled crystallography can provide a powerful means to reveal structural mechanisms of macromolecular function for cysteine-dependent enzymes.

A bidirectional scanning method designed for scanning transmission X-ray microscopy (STXM) with an S-shaped moving track is presented. This work removes the limitations on bidirectional scanning caused by motor backlash and vibration, and significantly improves the efficiency of STXM experiments.

This paper proposes a separation method for images composed of the superposition of a steady background and several foreground patterns with different subpixel motions. Application to the correction of X-ray radiographs allows moving particles that pollute the reconstruction to be erased.
