同步辐射XAFS数据处理干货，教你用同步辐射玩转材料科学！_同 …
2023年9月4日 · 其实XANES和EXAFS是对测出来的XAFS谱图能量区进行的一个划分，XANES (X-ray Absorption Near Edge Structure )是X射线近边吸收精细结构谱，而EXAFS (Extended X-Ray Absorption Fine Structure)是X射线延展边或者说拓展边吸收精细结构谱。 一般测试都是完整的XAFS谱。 以Cu-Foil为例，即以铜单质标样的XAFS谱为例来说， 以E0=8979ev为边，划分为三个区，如下图所示： 这样看是不是很清晰了呢？
CRESTS计划全球500 a以来的AMO与PDO重建数据报告
太平洋年代际震荡（pdo）与大西洋多年代际震荡（amo）作为全球年代际变化的主要模态，在全球气候变化研究中具有重要地位。 目前已有不少古气候记录用于重建过去500—1000 a以来的PDO和AMO变化。
Energy-Dispersive XAFS Studies on the Spontaneous Dispersion of PdO …
2004年5月20日 · Spontaneous dispersion and clustering processes of Pd were measured by means of the energy-dispersive EXAFS method. The spontaneous dispersion of bulky metal Pd into highly dispersed PdO was directly observed on the H-type zeolite in the atmosphere of O2.
