Deglitching procedure for XAFS

Journal of Synchrotron Radiation, 2001
A computer program for eliminating artifacts such as glitches and Bragg peaks of the polarized XAFS spectra is presented. It permits to easily locate and to eliminate from the EXAFS spectra the additional signals originated from the Bragg scattering by crystalline samples.

X-ray Absorption Fine Structure (XAFS) Studies of Oxide Glasses—A 45-Year Overview

Materials, 2018
X-ray Absorption Fine Structure (XAFS) spectroscopy has been widely used to characterize the short-range order of glassy materials since the theoretical basis was established 45 years ago.

29Si solid state NMR and Ti K-edge XAFS pre-edge spectroscopy reveal complex behavior of Ti in silicate melts

Progress in Earth and Planetary Science, 2020
An understanding of the mechanisms of Ti is incorporation into silicate glasses and melts is critical for the field of petrology. Trace-element thermobarometry, high-field-strength element partitioning, and the physical properties of magmas are all be ...

Slow crossover in YbXCu4 intermediate valence compounds [PDF]

, 2001
We compare the results of measurements of the magnetic susceptibility Chi(T), the linear coefficient of specific heat Gamma(T)=C(T)/T and 4f occupation number nf(T) for the intermediate valence compounds YbXCu4 (X = Ag, Cd, In, Mg, Tl, Zn) to the ...

Development of XAFS theory

Journal of Synchrotron Radiation, 2003
A major goal of theoretical simulations of X-ray absorption fine structure (XAFS) is to provide calculations for the interpretation and analysis of experimental data in terms of geometrical and electronic information. The extended region or EXAFS (50-2000 eV above an absorption edge) contains geometric information about the pair distribution function ...

Pd-catalyzed decarbonylation of furfural: Elucidation of support effect on Pd size and catalytic activity using in-situ XAFS

Journal of Catalysis, 2019
Palladium (Pd) clusters on zirconia (ZrO2) and single Pd atoms on ceria (CeO2) exhibited high catalytic activity and selectivity for decarbonylation of furfural to furan without additives in the liquid phase. To study the active size of Pd and changes in

Operando XAFS Studies on Rh(CAAC)-Catalyzed Arene Hydrogenation

ACS Catalysis, 2019
Rh K-edge X-ray absorption fine structure (XAFS) spectroscopy was used to examine the Rh-catalyzed arene hydrogenation of diphenyl ether by a combination of stoichiometric reactions of [(CAACCy,Dipp)Rh(COD)Cl] (Rh–Cl) (CAACCy,Dipp = cyclic alkyl amino ...

Correlated local distortions of the TlO layers in Tl$_2$Ba$_2$CuO$_{y}$: An x-ray absorption study

, 1994
We have used the XAFS (x-ray-absorption fine structure) technique to investigate the local structure about the Cu, Ba, and Tl atoms in orthorhombic Tl-2201 with a superconducting transition temperature T$_c$=60 K.
