EXAFS study of nickel exchanged into zeolite Y [PDF]
, 1986 EXAFS and near edge spectroscopy were used to monitor changes i n Ni coordination as a function of treatment conditions after aqueous exchange into zeolite Y.

Amplitude reduction in EXAFS [PDF]
Journal of Synchrotron Radiation, 1999 In real systems, inelastic processes remove photoelectrons from the elastic scattering channel. This reduces the amplitude of the EXAFS causing disagreement between the experimental and theoretically predicted amplitudes. Traditionally these discrepancies were treated by including two semi empirical reduction factors in the data analysis: a mean tree ...

Dopant site selectivity in BaCe0.85M0.15O3-δ by extended x-ray absorption fine structure [PDF]
, 2005 Rare earth doped BaCeO3 has been widely investigated as a proton conducting material. Trivalent dopants are generally assumed to fully occupy the Ce4+-site, and thereby introduce oxygen vacancies into the perovskite structure. Recent studies indicate the

LOCAL DISTORTIONS AND VOLUME CHANGES IN SEMICONDUCTORS - DONORS IN SILICON [PDF]
, 2002 Experiments giving impurity-induced lattice distortion can measure quite distinct quantities. In particular EXAFS (extended X-ray fine structure) measures nearest-neighbour distances, whereas both volume changes and recent spectroscopic data measure long-

Quick-EXAFS implementation on the general purpose EXAFS beamline at ESRF [PDF]
Journal of Synchrotron Radiation, 2011 The new implementation of QEXAFS acquisition on the general purpose EXAFS beamline BM29 at the European Synchrotron Radiation Facility is presented. By adopting a continuous-scan mode, a high signal-to-noise ratio can be maintained, together with a fixed exit beam and full compatibility with step-by-step operation, while reducing acquisition times to a

Cogent Engineering, 2020 This work advances the anharmonic correlated Einstein model to investigate how pressure and temperature affect the Debye–Waller factor and thermodynamic parameters of an intermetallic alloy. By using the anharmonic correlated Einstein model in extended X-

Physical Review Research, 2023 We develop a self-consistent Maxwell-Bloch formalism for the interaction of x-rays with two-dimensional crystalline materials by incorporating the Bloch theorem and Coulomb many-body interaction. This formalism is illustrated for graphene, by calculating
