Author Correction: Electronic origin of hydrogen storage in MOF-covered palladium nanocubes investigated by synchrotron X-rays

Communications Chemistry, 2018
The previously published version of this Article contained an error in Fig. 1. In panel c, the thickness of the HKUST-1 layer (3 nm) was incorrectly labelled. This error has been corrected in both the PDF and HTML versions of the Article.

High frequency beam oscillation keyhole dynamics in laser melting revealed by in-situ x-ray imaging

Communications Materials, 2023
Beam oscillation is an attractive method to achieve melt pool and microstructure control in laser powder bed additive manufacturing. Here, in-situ X-ray imaging and high-fidelity modeling reveal the unique keyhole dynamics in a kHz laser oscillation mode.

X-RAY LASER RESEARCH AT PALAISEAU [PDF]

Le Journal de Physique Colloques, 1986
We present the soft X-ray laser experiments performed at Greco "Interaction Laser-Matière" (Palaiseau). They are mainly concerned with Lithium-like ions of aluminum in plasmas produced by 1.06 µ Nd-laser. We describe the experimental set-up which performs time-dependent gain measurements.

Altered chemistry of oxygen and iron under deep Earth conditions

Nature Communications, 2019
Iron oxides prevail in the deep Earth, at extreme pressures and temperatures, with different stoichiometries than in ambient conditions. Here, high-pressure synchrotron X-ray spectroscopic measurements reveal the oxidation states of Fe and O in iron ...
