XAFS for Characterization of Nanomaterials
2016X-ray absorption fine structure (XAFS) spectroscopy studies the modification of the X-ray absorption coefficient, above the absorption edge of a specific element, due to the presence of neighboring atoms and delivers information on materials nano- and electronic structure.

Refinements in the theory of XAFS (x-ray absorption fine structure) are discussed. These include spherical wave corrections and multiple scattering contributions. The conventional theory, with these refinements included, can be recovered using effective scattering amplitudes, appropriate Debye-Waller factors, and many-body amplitude reduction factors.

Owing to its element specific and short-range nature, core-level X-ray absorption spectroscopy (XAS) is now widely used to elucidate the local structural, vibrational, and other physical properties of complex, aperiodic materials. In this Chapter we review the current theory of XAS including both extended (EXAFS) and near-edge (XANES) properties ...

Changes of structure and chemical states of catalysts have been successfully observed with XAFS under reaction conditions. Nowadays, a XAFS spectrum can be obtained even within several milliseconds by using quick XAFS (QXAFS) and dispersive XAFS (DXAFS) techniques.

Applications of XAFS to Nanostructures and Materials Science
2014I will firstly illustrate the role and the characteristics of XAFS as a probe of the local structure in materials and nano science. I will then provide a brief review of the use of the method in these fields, basing the discussion both on results which have stood the test of time and recent papers.
