Subnanometer Crystalline Regions using Coherent Electron Microdiffraction

这笔赠款探索了对扫描电子显微镜中小于一纳米的小区域进行分析的定量方法。在这项新的研究中，研究人员继续对显微衍射数据进行定量解释，并结合扫描电子显微镜的最新进展。利用扫描电子显微镜技术对纳米晶体、层状材料和颗粒/网络结构进行了分析。应改进表征小颗粒和薄膜的仪器和技术，并促进对催化剂性质的理解。

This grant explores quantitative approaches to the analysis of small regions less than one nanometer in the scanning transmission electron microscope. In this renewal of the research the investigators continue their quantitative interpretation of microdiffraction data combined with recent advances in scanning transmission electron microscope. Nanocrystals, layered materials, and particle/network structures are subject to analysis by scanning transmission electron microscope techniques. Improved instrumentation and techniques for characterizing small particles and thin films should result as well as advancing understanding of the nature of catalysts.
