Performance improvement of an X‐ray ionization beam position monitor for soft X‐ray free‐electron lasers

Journal of Synchrotron Radiation, EarlyView.
The performance evaluation and improvement of an X‐ray ionization beam position monitor for soft X‐ray free‐electron lasers is presented.An X‐ray ionization beam position monitor (XIBPM) has been developed and evaluated for beam position diagnostics at a soft X‐ray free‐electron laser (FEL).

It started off as a Cys, how did it end up like this? Identifying the extent of unmodelled oxidatively modified cysteines within the Protein Data Bank

Acta Crystallographica Section D, EarlyView.
This work examines data contained within 118 215 structures in the Protein Data Bank for unmodelled difference density concomitant with unmodelled oxidatively damaged cysteines. This analysis demonstrates that site‐specific oxidation of residues is a phenomenon of which the experimenter should be aware, and highlights the need for a suitable detection ...

Development of a multi-functional chamber for resonant X-ray scattering experiments in the tender X-ray regime at the PAL-XFEL

Journal of Synchrotron Radiation
The hard X-ray undulator line at Pohang Accelerator Laboratory X-ray Free Electron Laser (PAL-XFEL) provides a wide range of photon energies encompassing both the tender (2–5 keV) and hard (5–15 keV) X-ray regimes.

Comparing single-shot damage thresholds of boron carbide and silicon at the European XFEL

Journal of Synchrotron Radiation
Xray free-electron lasers (XFELs) enable experiments that would have been impractical or impossible at conventional X-ray laser facilities. Indeed, more XFEL facilities are being built and planned, with their aim to deliver larger pulse energies and ...

Ultrafast Charge Carrier Dynamics in Layered CuO‐TiO2 Heterostructure via Time‐Resolved Soft X‐Ray Absorption Spectroscopy

Advanced Materials Interfaces, Volume 13, Issue 11, 9 June 2026.
Schematic illustration of the carrier dynamics in the layered CuO∖TiO2 heterostructure. ABSTRACT Understanding the ultrafast carrier dynamics at the p‐n heterojunctions is indispensable for designing efficient photocatalysts. In this work, we used element‐specific time‐resolved soft X‐ray absorption spectroscopy (tr‐XAS) to investigate the ultrafast ...

Photoisomerization detected in a fully wavelength‐tunable rhodopsin mimic system

Acta Crystallographica Section D, Volume 82, Issue 6, Page 664-671, June 2026.
The mechanism of retinal photoswitching is illuminated in a designed rhodopsin mimic. Two mechanisms, a conventional cis–trans isomerization and an unprecedented `photodehydration', are observed at atomic resolution in single crystals.We describe the photoisomerization of the retinylidene protonated Schiff base in human retinol‐binding protein II ...

The structure of intact and active Photosystem II from Arabidopsis thaliana at 2.44 Å resolution

New Phytologist, Volume 250, Issue 5, Page 3014-3025, June 2026.
Summary Photosystem II (PS II) is a large membrane‐bound protein complex that catalyses light‐driven water oxidation in plants and cyanobacteria. The structure of PS II is well studied in cyanobacteria; however, there are very few PS II structures from plants.
