The combination of spectroscopy and microscopy enables unprecedented insights into the molecular and crystal structures of organic and inorganic materials, and their interfaces. This is relevant to the field of biomaterials in general and biominerals in particular.

Progress in the theory and interpretation of XANES
Coordination Chemistry Reviews, 2005There has been substantial progress in recent years, both in the theory and in ab initio codes for calculations of X-ray absorption spectra (XAS), and in particular, the near edge structure (XANES). This progress is a sequel to the successful development of the theory and interpretation of extended X-ray absorption fine structure (EXAFS).

Application of XANES in gamma dosimetry
Applied Radiation and Isotopes, 2019The thermoluminescence material, CaSO4:Dy, is widely used for the dosimetry of ionizing radiation due to its high sensitivity, low fading and wide dose range from μGy to few tens of gray. However, its application is limited at high doses due to non-linear and saturation effects. In this paper, X-ray Absorption Near Edge Structure (XANES) studies at the

In this short review of recent advances in XANES we have discussed the use of this spectroscopy to probe the geometry of local structure via multiple scattering effects in the real space and and the local partial unoccupied density of states in metals via the band structure approach.

Fast XANES perturbation schemes
Surface Science, 1985Abstract We investigate the applicability of renormalized forward scattering perturbation theory and single scattering approximations to the calculation of near-edge X-ray absorption spectra. We show that judicious combined use of these schemes can result in savings of computer time of almost an order of magnitude.

SbSI and Sb2S3, representative compounds of the AVBVICVII and A V 2 B VI 3 groups respectively, have awakened a remarkable interest for their physical and mechanical properties related to the low dimensional structure.

Abstract X-ray-absorption near edge structure (XANES) poses many theoretical challenges and a general quantitative theory remains elusive. We have studied structural contributions to XANES based on high-order multiple-scattering (MS) calculations, including X-ray polarization. Ab initio MS calculations of XANES are presented using a code FEFF6X, that

In this chapter we will cover the features close to an absorption edge, often called XANES (but sometimes NEXAFS). XANES is an acronym for X-ray Absorption Near-Edge Structure. This is usually considered the region around the absorption edge where there are dramatic changes in the density of states and/or individual transition intensities, so that a ...

Aluminium coordination in tektites: A XANES study
American Mineralogist, 2000Al K-edge XANES spectra were recorded for six tektites to obtain information on the local structure around Al. Albite, grossular, and andalusite were used as reference materials for Al in fourfold, sixfold, and five+sixfold coordination, respectively.
