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.

该资助探索了在扫描透射电子显微镜中分析小于一纳米的小区域的定量方法。 在这项研究的更新中，研究人员结合扫描透射电子显微镜的最新进展，继续对微衍射数据进行定量解释。 纳米晶体、层状材料和颗粒/网络结构可通过扫描透射电子显微镜技术进行分析。 应该改进用于表征小颗粒和薄膜的仪器和技术，并增进对催化剂性质的理解。
