Describes several specific spectrometric techniques that are very useful in elucidating the fundamental nature of matter: EXAFS--Extended X-Ray Absorption of Fine Structure; SEXAFS--which is EXAFS applied to Surface Phenomena; and XANES--X-Ray Absorption Near Edge Structures. Articles explain the phenomena and describe examples of X-ray absorption applications in several fields, including

Real-space multiple-scattering theory of EXAFS and XANES . J. J. Rehr, J. J. Kas and F. D. Vila. Nordita School on Photon -Matter Interaction Stockholm, Sweden Oct 3-7, 2016 EXAFS and XANES are becoming interdis­ ciplinary methods used in solid-state physics, biology, and chemistry, and are making impressive contributions to these branches of science. The present book gives a panorama of the research activity in this field. The theory of EXAFS was first formulated by Kronig (1931), and the theory of XANES by Kossel (1920).

Summary. The binding of Mn 2+ ions to ATP molecules has been studied by means of the fine-structure analysis of X-ray absorption spectra (EXAFS and XANES) at the K-edge of Mn using the synchrotron, radiation facility PULS in Frascati.

The bulk structural properties of the nickel cobaltite, NiCo 2 O 4, prepared by the thermal decomposition of carbonates, sol–gel methods, and the decomposition of hydroxides, have been examined by X-ray powder diffraction (XRD) and X-ray absorption spectroscopy (EXAFS and XANES).

Pd/H-Beta catalysts with different silica-to-alumina ratio prepared by an impregnation method have been studied by XANES/EXAFS, IR, XRD and TEM.

Samples annealed for 5 h at temperatures between 250 ~ to 600 ~ have been studied. The XANES and EXAFS data are compatible with the existence of Ni 2+ and Ni 3+. The structural data indicate that Co is present as Co 2+ and Co 3+.The bulk cation distribution appears to be dependent on the synthesis procedure. The results of the surface examination by X-ray photoelectron spectroscopy Advantages of XANES vs. EXAFS • Spectra simpler to measure than EXAFS: features intense, concentrated in small energy region.

EXAFS/XANES is a method often used to study copper, but it has seldom been used in research regarding copper ruby glass. An exception is the study by Nakai 

2014-10-31 Solution XANES and EXAFS analysis of active species of titanium, vanadium complex catalysts in ethylene polymerisation/dimerisation and syndiospecific styrene EXAFS and XANES structural characterization of bimetallic AuPd vapor derived catalysts.

Apparently the conceptual principles of these two systems are technically the same, which is one of the limitations of this definition, because there is no clear principle definition to distinguish these two systems.

During the lectures, the information content of XANES and EXAFS was covered, as well as important considerations for planning these types of experiments; the lectures were also recorded and are available for download. hiXAS offers a complete lab-based solution for Extended X-ray Absorption Fine Structure (EXAFS) and X-ray Absorption Near Edge Structure (XANES) measurements. In a compact footprint, it integrates x-ray tube source, high-resolution spectrometer, and hybrid detector together with a software suite to control instrument functions and analyze data.

contribute to the absorption cross section. XANES, x-ray absorption near edge structure, is sometimes also called NEXAFS, near edge x-ray absorption fine structure. It is defined as partial analysis of x-ray absorption, and the range of XANES is between the threshold and where EXAFS begins. The full EXAFS spectrum for NiO NPs has been simulated by Anspoks et al.
