The exchange interactions JNN and JNNN are determined by the intermixing of the 3d8(Ni2+) and 2p(O2−) states, which can be directly accessible by the X-ray absorption near-edge-structure (XANES) spectroscopy, being sensitive to a variation of the local electronic and atomic structures ...

edge (4038 eV) to investigate Ca speciation in soils. We present Ca K-edge XANES spectra of standard compounds with relevance in soils (e.g. calcite, dolomite, hydroxyapatite, anorthite, clay mineral-adsorbed Ca; Ca oxalate, formate, acetate, citrate, pectate, phytate). Calcium XANES spectra...
=0.00, 0.25, 0.50 and 0.75) system has been carried out with Fe K-edge X-ray absorption spectroscopic studies. It is found out that the Fe ions are placed in two different symmetric sites, such as tetrahedral and octahedral sites in the compounds from Fe K-edge X-ray absorption near ...
Li K-edge XANES and Li(1s) XPS spectra of various lithium complexes can be measured under the suitable measuring conditions. A great variety of spectra have been obtained. Li K-edge XANES spectra are shown in Fig. 2. They have four or five peaks ...
为阐明KCO微立方体在K+吸收/释放时的电荷补偿机制,我们收集了原位XAS谱,如XANES。随着电势从1.7升高到4.0 V,Co K-edge谱线明显向高能区域移动(~1.3 eV),表明Co3+氧化为Co4+。KCO微立方体的原子间距离信息也通过EXAFS光谱得以揭示。在充电过程中,我们在KCO微立方体的第一个TM-O配位壳层中观察到傅里叶变换幅...
High-resolution B K-edge X-ray absorption near-edge structure (XANES) spectra of K 2 O-SiO 2 -B 2 O 3 -P 2 O 5 glasses are reported using synchrotron radiation. Two prominent features, peak a at about 194.0 eV and peak b at about 198.0 eV, are observed.
