Upgrade of the High Resolution Electron Microscope

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。该设备将促进以下领域的研究：a)过渡金属氧化物纳米晶体电子衍射结构分析的应用；B)利用电子衍射确定在光合作用中重要的光束敏感的生化化合物的结构；c)通过聚焦高分辨率电子显微镜图像的出口波重建，以更高的精度确定原子排列。该设备将对普林斯顿大学广泛学科的前沿研究项目产生重大影响，包括材料化学和生物化学。此外，该设备将使仪器更加人性化，从而使学生更容易使用。学院将开设一门利用高分辨率透射电子显微镜进行结构测定的新课程。

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.
