With this award from the Major Research Instrumentation (MRI) program Professor Vincent Remcho and colleagues Chih-hung Chang, Jamie Kruzic, Mas Subramanian and John Conley from Oregon State University will acquire a high resolution field emission transmission electron microscope (TEM). The proposal will impact materials research in a large number of areas, including studies of ultra-high temperature alloys, advanced ceramics, steels, bulk metallic glasses, solar energy materials, thin film transistors, dielectrics, nonlinear optical materials, microfluidic devices for applications in chemical analysis, the effect of nanocrystals on polymer matrices, the composition of atmospheric aerosol particles, and the structures of novel marine organisms.A transmission electron microscope is one of the most powerful tools available for the characterization of materials. A beam of electrons penetrates a thin layer of sample resulting in an image of the sample. The electron microscope can provide higher resolution and maginfication than a microscope using light to probe the material. It can provide useful details of the material down to near atomic size levels. This instrumentation will provide microscopy training and research opportunities to large numbers of students across many fields including chemistry, biology, physics, materials and engineering.

有了这项来自主要研究仪器（MRI）计划的奖项，来自俄勒冈州州立大学的Vincent Remcho教授和同事Chih-hung Chang，Jamie Kruzic，Mas Subramanian和John Conley将获得高分辨率场发射透射电子显微镜（TEM）。 该提案将影响许多领域的材料研究，包括超高温合金、先进陶瓷、钢、大块金属玻璃、太阳能材料、薄膜晶体管、非线性光学材料、化学分析应用的微流体装置、纳米晶体对聚合物基质的影响、大气气溶胶颗粒的组成、和新型海洋生物的结构。透射电子显微镜是表征材料的最有力的工具之一。电子束穿透样品的薄层，产生样品的图像。电子显微镜可以提供比使用光探测材料的显微镜更高的分辨率和放大率。它可以提供材料的有用细节，低至接近原子大小的水平。该仪器将为包括化学、生物学、物理学、材料和工程学在内的许多领域的大量学生提供显微镜培训和研究机会。
