最近Khalil Amine 大叔就在 nature energy上提出了目前对锂离子电池最先进的表征技术手段:in situXAFS, in situTEM, in situNMR, in situ XRD, in situSEM, operandoDEMS(原位差分电化学质谱)等等,反正一句话 in situ/operando 这单词不管和哪个技术结合,哪个技术就能开花结果。当然,近几年大家也一定在不同的杂...
In situ TEM studies of the nature of precipitates in preliminary thermal annealing-induced colonies in Cz-silicon crystalThe behaviour of colonies of precipitate particles has been studied in Czochralski-grown silicon by in-situ annealing (850掳C for 10h). The rate of particle growth was estimated...
原位透射电子显微学(in-situTEM)是指直接在原子层次观察样品在力、热、电、磁作用下以及化学反应过程中的微结构演化及进行表征的过程,近年来成为材料研究的热门领域。 与原位对应的非原位(ex-situ)是指实验过程是在电镜外完成,实验完成后再将样品放进电镜中观察,通过对比实验前和实验后样品的图像来推断实验过程中样...

To show the evolution of atomically dispersed Pt species, we have chosen an area showing only the presence of a few Pt clusters without Pt nanoparticles to perform the in situ TEM experiments. When the sample was exposed to H2 (0.1 torr) at 350 °C, a few Pt clusters (below 0....
Figure 5.15.TEM in situ deformation experiment of a predeformed Cu single crystal at 293 K. 200 kV. Foil plane (564): (a) and (b) two successive positions of the cross-slipping dislocation (labelled 1 and 2, respectively); (c) corresponding schematics. T is the tensile axis. ...
deformation behavior, in-situ microcompression of Mg [21¯1¯0] pillars of various sizes from 0.5 μm to 4 μm was carried out in a scanning electron microscope (SEM) and also in a transmission electron microscope (TEM), covering strain rates from 10−4 to 10−2 s−1. ...
X-ray absorption spectroscopy (XAS) has become an indispensable tool to in situ investigate dynamic natures of electrocatalysts but still suffers from limited energy resolution, leading to significant electronic transitions poorly resolved. Herein, we highlight advanced X-ray spectroscopies beyond ...
