摘要:... We present a combined DFT-assisted analysis based on both full-potential XANES simulation and Wavelet Transform Analysis (WTA) applied to computed EXAFS signals. The resulting theoretical insights set the bases for an easier and more robust interpretation of the XAS data coll...

摘要:... For all samples, including a non-heated one, X-ray absorption near edge structure (XANES) spectra were measured at the Ca-K-edge. Two of the characteristic features of these spectra were used for obtaining for the first time a calibration curve for determining the firing t...

摘要:Abstract(#br)X-ray absorption near-edge spectroscopy (XANES) is becoming an extremely popular tool for material science thanks to the development of new synchrotron radiation light sources. It provides information about charge state and local geometry around atoms of interest in ...

摘要:Abstract(#br)X-ray absorption near edge structure (XANES) measurement is one of the most powerful tools for the evaluation of a cation valence state. XANES measurement is sometimes the only available technique for the evaluation of the valence state of a dopant cation, which...

摘要:Abstract(#br)Sequential chemical extraction and synchrotron-based XANES spectroscopy techniques were used to identify P species in two ashes before and after addition to a prairie soil. The used ashes were: meat and bone meal ash (MBMA) and dried distillers grains ash (DDGA) plus...

摘要:Abstract(#br)In the last decade the appearance of progressively more sophisticated codes, together with the increased computational capabilities, has made XANES a spectroscopic technique able to quantitatively confirm (or discard) a structural model, thus becoming a new fundament...

摘要:... X-ray diffraction (XRD), X-ray absorption near edge structure (XANES), extended X-ray absorption fine structure (EXAFS) and photoluminescence (PL) measurements were performed to analyze the crystal structure, local atomic/electronic structure and luminescence properties of...

摘要:Abstract(#br)The effect of adventitious contamination on total-electron-yield XANES analysis of carbon species of diamond-like carbon (DLC) films was investigated. XPS and XANES measurements on a DLC sample with different amounts of contamination were carried out in the same anal...

摘要:... Soil P speciation was analyzed by P K-edge XANES spectroscopy and chemical fractionation, sorption isotherms were constructed, and dissolved P was measured as a function of pH. The XANES fitting results showed that organic P and P adsorbed to Fe and Al (hydr)oxides were commo...

摘要:Abstract(#br)Herein, we present Cu K-edge XANES (X-ray Absorption Near Edge Structure) simulations for different framework interacting Z-Cu II species proposed to form as an active site after high-temperature activation in Cu-exchanged chabazite zeolites, representing promising m...
