X-ray Absorption Fine Structure (XAFS) Analysis of Titanium-implanted Soft Tissue
Dental Materials Journal, 2007 Tissues contacting Ti dental implants were subjected to X-ray absorption fine structure (XAFS) analysis to examine the chemical state of Ti transferred from the placed implant into the surrounding tissue. Nine tissues that contacted pure Ti cover screws for several months were excised in a second surgery whereby healing abutments were set.

Measurements of photon interference X-ray absorption fine structure (πXAFS)
Journal of Synchrotron Radiation, 2001 Experimental data are presented which demonstrate the existence of a fine structure in extended X-ray absorption spectra due to interference effects in the initial photon state (πXAFS). Interference occurs between the incident electromagnetic wave and its coherently scattered waves from neighboring atoms.

X-ray excited optical luminescence (XEOL) detection of x-ray absorption fine structure (XAFS)
Journal of Chemical Physics, 1998The x-ray excited optical luminescence (XEOL) from a variety of rare-earth ions was used as a detection mode for the collection of L-edge x-ray absorption fine-structure (XAFS) data. In order to understand the source of the observed optical signal, advantage is taken of the known luminescent response of f ions in a variety of transparent host materials.

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.

Fourteenth International Conference on X-ray Absorption Fine Structure (XAFS-14)
Synchrotron Radiation News, 2010The university town of Camerino in central Italy hosted the Fourteenth International Conference on X-ray Absorption Fine Structure (XAFS-14) in July 2009. This historical town, surrounded by the rolling hills and beautiful countryside of the Marche region, was an ideal location for a stimulating conference, providing an optimal mix of good ...

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.
