Abstract

Hydrogen Detection

By combining electron loss spectroscopy with in-situ gas TEM, hydrogen concentration is measured in a model system consisting of cubic palladium nanoparticles, with a lateral resolution down to 4 nm. The versatility of in-situ TEM allows to link together microstructure, hydrogen concentration and local strain, opening up a new chapter in hydrogen research.

局部氢浓度和分布在Pd纳米颗粒：原位STEM-EELS方法（小16/2025）

氢的检测通过结合电子损失光谱和原位气体透射电镜，在一个由立方钯纳米颗粒组成的模型系统中测量氢的浓度，横向分辨率低至4纳米。原位透射电镜的多功能性可以将微观结构、氢浓度和局部应变联系在一起，为氢研究开辟了新的篇章。更多内容见文章编号2407092，Svetlana Korneychuk及其同事。
