Theoretical investigation of thermal disorder in CuCo alloys

Results in Physics, 2020
In this work, we investigate thermal disorder in intermetallic CuCo alloys by extending the anharmonic correlated Einstein model in extended X-ray absorption fine structure (EXAFS) theory.

Laboratory EXAFS facilities [PDF]

, 1988
This chapter has demonstrated that high quality XANES and EXAFS spectra can be collected with laboratory EXAFS facilities. The limitations of these facilities have been discussed and it has been shown that synchrotronlike reso lutions, which are ...

Unveiling the local structure of the amorphous metal $$\text {Fe}_{(1-x)}\text {Zr}_x$$ Fe ( 1 - x ) Zr x combining first-principles-based simulations and modelling of EXAFS spectra

Scientific Reports, 2023
Amorphous alloys exhibit useful properties such as the excellent soft magnetic behaviour of Fe-based metallic glasses. The detailed structure of amorphous $$\text {Fe}_{(1-x)}\text {Zr}_x$$ Fe ( 1 - x ) Zr x with x = 0.07, 0.10, and 0.20 is in this work ...

STRUCTURAL STUDY OF BIS(2,6-BIS(PYRAZOL-3-YL)PYRIDINE)NICKEL(II) BY CALORIMETRY AND EXAFS SPECTROMETRY

Indonesian Journal of Chemistry, 2010
The main aim of this work is to reveal the complex formation of 2,6-bis(pyrazol-3-yl)pyridine, bpp, with nickel(II) perchlorate in DMF by calorimetric stepwise complex formation and then followed by EXAFS spectrometry.

X-ray absorption spectroscopy of lanmodulin-derived peptides bound to rare earth elements

Journal of Synchrotron Radiation
A sustainable and robust supply chain of rare earth elements (REEs) is necessary to meet our consumer, national security and clean energy goals. However, current intra-REE separation technologies (e.g.
