Serial crystallography on in vivo grown microcrystals using synchrotron radiation

open access: yesIUCrJ, 2014
Crystal structure determinations of biological macromolecules are limited by the availability of sufficiently sized crystals and by the fact that crystal quality deteriorates during data collection owing to radiation damage. Exploiting a micrometre-sized

Coherence of femtosecond single electrons exceeds biomolecular dimensions

open access: yes, 2013
Time-resolved diffraction and microscopy with femtosecond electron pulses provide four-dimensional recordings of atomic motion in space and time. However, the limited coherence of electron pulses, reported in the range of 2–3 nm, has so far prevented the

Recent results in time resolved serial femtosecond crystallography at XFELs

open access: yesCurrent Opinion in Structural Biology, 2020
Time-resolved serial femtosecond crystallography (tr-SFX) methods exploit slurries of crystalline samples that range in size from hundreds of nanometers to a few tens of micrometers, at near-physiological temperature and pressure, to generate atomic resolution models and probe authentic function with the same experiment. 'Dynamic structural biology' is

Convergent-beam attosecond x-ray crystallography

open access: yesStructural Dynamics
Sub-ångström spatial resolution of electron density coupled with sub-femtosecond to few-femtosecond temporal resolution is required to directly observe the dynamics of the electronic structure of a molecule after photoinitiation or some other ultrafast ...

Serial millisecond crystallography of membrane and soluble protein microcrystals using synchrotron radiation

open access: yesIUCrJ, 2017
Crystal structure determination of biological macromolecules using the novel technique of serial femtosecond crystallography (SFX) is severely limited by the scarcity of X-ray free-electron laser (XFEL) sources. However, recent and future upgrades render

Soft x-ray absorption spectroscopy of metalloproteins and high-valent metal-complexes at room temperature using free-electron lasers [PDF]

open access: yes, 2017
X-ray absorption spectroscopy at the L-edge of 3d transition metals provides unique information on the local metal charge and spin states by directly probing 3d-derived molecular orbitals through 2p-3d transitions.
