XAFS Data Interchange: A single spectrum XAFS data file format

Journal of Physics: Conference Series, 2016
We propose a standard data format for the interchange of XAFS data. The XAFS Data Interchange (XDI) standard is meant to encapsulate a single spectrum of XAFS along with relevant metadata.

Revisiting the crystal structure of the equilibrium S (Al2CuMg) phase in Al–Cu–Mg alloys using X-ray absorption spectroscopy (XAFS) [PDF]

Materialia, 2019
Even though, the crystal structure of the intermediate (S') and the equilibrium S (Al2CuMg) phase were subject of many investigations by using mostly imaging or diffraction techniques, the results remain still controversial.

Dispersion and stability mechanism of Pt nanoparticles on transition-metal oxides

Scientific Reports, 2022
The heterogeneous catalysts of Pt/transition-metal oxides are typically synthesized through calcination at 500 °C, and Pt nanoparticles are uniformly and highly dispersed when hydrogen peroxide (H2O2) is applied before calcination.
