2019年4月5日 · XAS observations indicate that the carboxylic groups of the bacterial fraction and the ferric hydroxyl groups of the Fe/Al hydroxide are mainly responsible for Pb adsorption to …

2023年10月15日 · Elucidation of elemental speciation at low concentration in complex matrices by XAS is shown. Pb/Zn smelter slag is a hazardous industrial waste from the Imperial Smelting …

One example is Pb. On the main XAS page there is a figure showing all the absorption edges of Pb that are in the X-ray range. At CAMD the L and M edges are available for research.

For the first time combined X-ray absorption spectroscopy (XAS) and X-ray diffraction (XRD) experiments were carried out to probe the short- and long-range order in lanthanum-modified …

1994年8月8日 · In situ X-ray absorption spectroscopy (XAS) was used to study the structure of adsorbed Pb on carbon-supported Pt in 1 M HClO 4 + 5 × 10 −3 M Pb 2+, in the potential …

Our calculations of the p-DOS show that the top of the valence band (VB) is composed of Br 4p orbitals, with a non-negligible proportion of Pb 6s orbitals and a minor contribution of Pb 6p ...

2010年11月16日 · The quantitative analysis of soil samples XANES allowed to individuate four components as the main responsible for Pb retention in calcareous soils: the carbonate …

XAS（synchrotron X-ray absorption spectroscopy）以X射线光子能量作为变量，测定材料的X射线吸收系数。 每个吸收边与材料中存在的特定原子有关，更具体地说，与将特定原子核轨道电 …

Pb is Copper structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Pb is bonded to twelve equivalent Pb atoms to form a mixture of corner, edge, …

We have investigated the local electronic structure of PbCrO3 by conducting x-ray absorption spectroscopy at the lead L3 and chromium L2,3 edges. We found that lead is divalent and …
