XFEL and HHG interaction with matter: Effects of ultrashort pulses and random spikes

Matter and Radiation at Extremes, 2021
The theory of photoionization describing the interaction of x-ray free-electron laser (XFEL) pulses and high-harmonic-generated (HHG) radiation is generalized to ultrashort laser pulses, where the concept of the standard ionization probability per unit ...

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.

Effect of Adatom Energy on the Interfacial and Surface Morphology of Pulsed DC Sputtered Ruthenium Thin Films

Surface and Interface Analysis, Volume 58, Issue 5, Page 326-333, May 2026.
ABSTRACT In the present study, we have analyzed the growth profile of ruthenium (Ru) thin films, deposited using pulsed direct current (DC) magnetron sputtering technique, by varying the sputtering voltages in the range of 150–420 V. The grazing incidence X‐ray reflectivity (GIXRR), time‐of‐flight secondary ion mass spectrometry (ToF‐SIMS), and atomic ...
