项目摘要

This energy dispersive X-ray spectrometer capable of detecting light elements and a computer work station with software capable of performing quantitative thin film chemical analysis will enable faculty and graduate students to perform quantitative thin film microchemical analysis at the University of Missouri-Rolla. This spectrometer is to be installed on an existing transmission electron microscope. Ancillary equipment that includes a TV camera, cold stage, hot stage and scanning transmission device are also requested. Current research is being performed on synthesis of: 1) novel electrodeposited shape memory alloys that cannot be produced by the standard thermal process, 2) ceramic superlattices that have unique electrical and optical properties, and 3) new rare earth magnetic materials that are technologically important. %%% An energy dispersive X-ray spectrometer capable of detecting light elements and a computer work station with software capable of performing quantitative thin film chemical analysis is requested.

Current research is being performed on electrodeposited shape memory alloys and ceramic superlattices, and new rare earth magnetic materials. Materials processing is a central theme in each of these projects and an analytically equipped transmission electron microscope is essential for the characterization of these new and exciting materials.

这种能够检测轻元素的能量色散 X 射线光谱仪和带有能够执行定量薄膜化学分析的软件的计算机工作站将使密苏里大学罗拉分校的教师和研究生能够执行定量薄膜微量化学分析。该光谱仪将安装在现有的透射电子显微镜上。还需要包括电视摄像机、冷台、热台和扫描传输装置等辅助设备。目前的研究正在进行合成：1）无法通过标准热工艺生产的新型电沉积形状记忆合金，2）具有独特电学和光学特性的陶瓷超晶格，以及3）技术上重要的新型稀土磁性材料。 %%% 需要能够检测轻元素的能量色散X射线光谱仪和具有能够进行定量薄膜化学分析的软件的计算机工作站。该光谱仪将安装在现有的透射电子显微镜上。目前的研究正在进行电沉积形状记忆合金和陶瓷超晶格以及新型稀土磁性材料。材料加工是每个项目的中心主题，配备分析设备的透射电子显微镜对于表征这些令人兴奋的新材料至关重要。
