Ambient pressure X-ray absorption spectroscopy at ME2-BL02B of SSRF and its application in catalysis

open access: yesHe jishu, 2021
BackgroundThe traditional soft X-ray absorption spectroscopy (XAS) method can only work under ultra-high vacuum conditions and cannot be used to detect changes in the electronic structure of samples under real conditions.

X-ray Absorption Spectroscopy of Phosphine-Capped Au Clusters

open access: yesInorganics, 2023
The structural determination of ultrasmall clusters remains a challenge due to difficulties in crystallisation. Often the atomically precise clusters undergo structural change under the influence of the environment.

Laboratory-based X-ray spectrometer for actinide science

open access: yesJournal of Synchrotron Radiation, 2023
X-ray absorption and emission spectroscopies nowadays are advanced characterization methods for fundamental and applied actinide research. One of the advantages of these methods is to reveal slight changes in the structural and electronic properties of ...

Gallium Selenide and Rubidium Iodide Filling of Single-Walled Carbon Nanotubes as p, and n-Dopant Chemical Compounds

open access: yesEngineering Proceedings, 2023
I filled the single-walled carbon nanotubes (SWCNTs) with gallium selenide (GaSe) and rubidium iodide (RbI) as p- and n-dopant chemical compounds. The filling was confirmed by high-resolution transmission electron microscopy.

Oxygen Hole Character and Lateral Homogeneity in PrNiO2+δ Thin Films

open access: yesFrontiers in Physics, 2022
Using x-ray absorption spectroscopy with lateral resolution from the submillimeter to submicrometer range, we investigate the homogeneity, the chemical composition, and the nickel 3d- oxygen 2p charge transfer in topotactically reduced epitaxial PrNiO2+δ

Combined X-ray absorption and SEM–EDX spectroscopic analysis for the speciation of thorium in soil

open access: yesScientific Reports, 2023
Mobility and bioavailability of radionuclides in the environment strongly depend on their aqueous speciation, adsorption behavior and the solubility of relevant solid phases. In the present context, we focus on naturally occurring Th-232 at a location in

The crucial contribution of X-ray fluorescence spectroscopy in medicine

open access: yesComptes Rendus. Chimie, 2021
This contribution tries to indicate to the clinician what kind of information can be investigated through X-ray fluorescence, what kind of information can be extracted from this spectroscopy and finally how it competes with other tools described in ...
