Synchrotron X-ray Absorption Spectroscopy Study of Local Structure in Al-Doped BiFeO3 Powders

open access: yesNanoscale Research Letters, 2019
The Al-doped BiFeO3, i.e., BFA x O powder samples with x = 0, 0.025, 0.05, and 0.1, were prepared via the hydrothermal route. The effects of Al substitution on the structural, electrical, and optical properties of BFA x O samples were investigated. It is

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

open access: yesScientific 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.

X-ray absorption fine structure (XAFS)-based radionuclide research at the KIT Light Source

open access: yesSafety of Nuclear Waste Disposal, 2023
Abstract. In the past two decades, X-ray absorption spectroscopy (XAS) and related synchrotron-based radionuclide speciation techniques have become indispensable, supporting open issues in fundamental radiochemistry and nuclear waste disposal alike. Physicochemical structure information – encoded in the element-specific X-ray absorption fine structure (
