Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2005
We report the results of the intermediate valence compound EuCu2Si2 local electron and crystalline structure studies by means of L3-Eu XANES and K-Cu EXAFS spectroscopy. Temperature dependence of the europium valence has been defined. In EXAFS studies, we have analyzed Cu atoms local environment and have revealed bond length and rigidity parameters of ...

XAFS Studies of Fe−SiO2 Fischer‐Tropsch Catalyst During Activation in CO, H2, and Synthesis Gas
ChemCatChem, 2019Highly dispersed catalysts are widely used in industry and academia because of their large surface active sites. However, the predominant short‐range ordered structures in catalysts cannot be revealed by bulk characterization tools.

Molecular Dynamics Simulations and XAFS (MD-XAFS)
2016MD-XAFS (Molecular Dynamics X-ray Adsorption Fine Structure) makes the connection between simulation techniques that generate an ensemble of molecular configurations and the direct signal observed from X-ray measurement. Due to the fact that the signal is most sensitive to the structure nearest to a photoelectron source, an understanding of XAFS signal

In-situ XAFS and SERS study of self-healing of passive film on Ti in Hank's physiological solution
, 2019The self-healing of passive film on Ti after being damaged in Hank's physiological solution greatly fluctuates with time and its mechanism has been investigated by in-situ X-ray absorption fine structure spectroscopy (XAFS) and surface enhanced Raman ...

Abstract We present an X-ray absorption study of zinc selenide at the Zn and Se K-edges. The analysis of the X-ray absorption fine structure (XAFS) was done in the framework of the multiple-scattering theory. The total XAFS signals have been obtained; they are in good agreement with the experimental data.

XAFS in dilute magnetic semiconductors
Dalton Transactions, 2013X-Ray absorption fine structure (XAFS) spectroscopy has experienced a rapid development in the last four decades and has proved to be a powerful structure characterization technique in the study of local environments in condensed matter. In this article, we first introduce the XAFS basic principles including theory, data analysis and experiment in some
