Recent advances in x-ray absorption spectroscopy
TL;DR: In this article, a review of the application of x-ray absorption spectroscopy to surface physics and magnetism of ultrathin 3D and 5D films is presented.
Journal ArticleDOI
XAFS study of adsorbed and mineral forms of phosphate
TL;DR: Phosphorus KXANES spectra for Fe-phosphates were characterized by a unique pre-edge feature near -3 eV (relative energy) that increased in intensity with increasing mineral crystallinity and was very weak for phosphate adsorbed on goethite.

In Situ X-ray Absorption Spectroscopy Studies of Nanoscale Electrocatalysts.
TL;DR: This paper reviews the literatures to-date on new applications of in situ XAS (e.g., single-atom catalysts, surface reactions, nanoparticle size, and site occupation) that traditional XAS has not touched and goes over the basic principles of XAS.

Curve fitting analysis of near‐edge core excitation spectra of free, adsorbed, and polymeric molecules
Duane A. Outka,Joachim Stöhr +1 more
TL;DR: In this paper, the deconvolution of both x-ray absorption (NEXAFS) and electron impact near-edge excitation spectra of free, chemisorbed, condensed, and polymeric molecules is considered.
