With support from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Chemistry Department at Princeton University will upgrade their high resolution electron microscope. This equipment will facilitate research in the following areas: a) the application of structural analysis by electron diffraction of nanometer-size crystals of transition metal oxides; b) the use of electron diffraction to determine the structure of beam sensitive biochemical compounds important in photosynthesis; and c) the use of exit wave reconstructions from through focus high resolution electron microscopic images to determine atomic arrangements with a much higher accuracy. This equipment will have a significant impact on cutting-edge research projects across a wide range of disciplines at Princeton, including materials chemistry and biochemistry. In addition, the equipment will make the instrument more user-friendly, so that it will be more accessible to students. The PI will introduce a new course in structure determination using high resolution transmission electron microscopy.

在化学研究仪器和设施（CRIF）计划的支持下，普林斯顿大学化学系将升级他们的高分辨率电子显微镜。 这一设备将促进以下领域的研究：a）通过电子衍射对过渡金属氧化物纳米晶体进行结构分析; B）利用电子衍射确定对光合作用重要的光束敏感的生化化合物的结构;以及c）使用来自通过聚焦的高分辨率电子显微镜图像的出射波重建来确定具有高得多的精度 该设备将对普林斯顿大学材料化学和生物化学等多个学科的前沿研究项目产生重大影响。 此外，这些设备将使该仪器更加方便用户，使学生更容易使用。 PI将介绍一个新的课程，在结构测定使用高分辨率透射电子显微镜。
