Speciation using X-ray absorption fine structure (XAFS)
Review Journal of Chemistry, 2015X-ray absorption fine structure (XAFS) spectroscopy is in use as a unique fingerprinting technique. By employing spectra of well-defined chemical species (standards), XAFS can be analyzed for speciation, i.e., identification and quantification of the different chemical species present in a sample.

X–ray absorption fine structure (XAFS) of Si wafer measured using total reflection X–rays
Spectrochimica Acta, Part B: Atomic Spectroscopy, 1999Abstract Extended X–ray absorption fine structure (EXAFS) and X–ray absorption near edge structure (XANES) spectra of a Si wafer are measured using grazing incidence X–rays. The spectra are measured using the total electron yield method. Fourier transform of the measured EXAFS oscillation is compared among different glancing angles.

In this study, X-ray absorption fine structure (XAFS) spectroscopy has been used to further elucidate the binding mechanisms of Zn(II) to calcium silicate hydrate (C-S-H), the quantitatively most important cement mineral. Such knowledge is essential for the assessment of the longterm behavior of cement-stabilized waste materials. XAFS spectra of the Zn(

Abstract X-ray absorption fine structure (XAFS) spectroscopy has proven to be a valuable tool in defining valence states of multivalent elements in minerals and glasses that can then be used as oxybarometry proxies. First row transition multivalent elements Ti, V, Cr, and Fe are common targets.

X-Ray Absorption Fine Structure (Xafs) Studies Of Cobalt Silicide Thin Films
MRS Proceedings, 1998ABSTRACTCobalt silicide thin films, prepared on Si(100) wafers, have been studied by X-ray absorption near edge structures (XANES) at the Si K-, L2,3 and Co K-edges utilizing both total electron (TEY) and fluorescence yield (FLY) detection as well as extended X-ray absorption fine structure (EXAFS) at the Co K-edge.
