Time-resolved β-lactam cleavage by L1 metallo-β-lactamase
Nature Communications, 2022 Metallo-β-lactamases cleave β-lactam moiety of many broadly used antibiotics. Here the authors captured mechanistic details of the enzyme catalyzed reaction using time-resolved xray synchrotron serial crystallography.

Two-way tuning of structural order in metallic glasses
Nature Communications, 2020 While metallic glasses are expected to have tunable structures, these have rarely been demonstrated. Here, the authors combine temperature and pressure to show a two-way structural tuning in rare earth-based metallic glasses beyond the nearest-neighbor ...

Time Resolved Two Dimensional X-Ray Densitometry of a Two Phase Flow Downstream of a Ventilated Cavity [PDF]
, 2013 To measure the void fraction distribution in gas-liquid flows, a two-dimensional x-ray densitometry system was developed. This system is capable of acquiring a two-dimensional projection with a 225 cm2 area of measurement through 21 cm of water.

Coherent Compton X-Ray Sources [PDF]
Journal of X-Ray Science and Technology: Clinical Applications of Diagnosis and Therapeutics, 1994 Coherent x rays can be produced by scattering of laser light by a beam of relativistic electrons, provided that the electron beam is density modulated or the scattering is done at, or near, 90°. Since the coherent scattering is proportional to N 2 , where N is the number of electrons, and the

The novel high-pressure/high-temperature compound Co12P7 determined from synchrotron data
Acta Crystallographica Section E: Crystallographic Communications, 2020 The structural properties of cobalt phosphides were investigated at high pressures and temperatures to better understand the behavior of metal-rich phosphides in Earth and planetary interiors. Using single-crystal X-ray diffraction synchrotron data and a
