MRI: Acquisition of a Scanning Electron Microscope/Scanning Transmission Electron Microscope

德克萨斯大学奥斯汀分校化学系将为德克萨斯中部学术科学和工程界获得一台场发射扫描电子显微镜/扫描透射电子显微镜（FE-SEM/STEM）。该仪器将对多个领域的研究产生重大影响，从药物输送系统中的软组织应用，到通过催化，探测硅藻和水泥基材料的细胞壁，以及分析燃料电池材料的纳米结构。此外，它将填补一个关键的空白，在表征纳米尺度的材料使用一个骨干，用户友好的仪器，吸引了工程，材料科学和自然科学学科的强烈需求。扫描电子显微镜/扫描透射电子显微镜是一种强大的工具，用于成像从纳米颗粒到聚合物和薄膜的各种材料。该仪器提供了这些材料的拓扑结构和成分信息。它是研究此类材料性能和行为的重要分析工具。这是一项联合奖励，包括来自德克萨斯材料研究所（TMI）和纳米与分子科学与技术中心（CNM）附属的14个不同部门的11个研究小组作为主要用户和46个研究小组作为次要用户，以及德克萨斯纪念博物馆和休斯顿德克萨斯大学健康科学中心的外部用户。德克萨斯大学奥斯汀分校还将允许学生进入附近地区规模较小的德州大学。该仪器将用于学士、硕士、博士和博士后学生的研究训练，从而为他们在科学和工程领域的职业生涯做好准备。

The Department of Chemistry at the University of Texas at Austin will acquire a field emission scanning electron microscope/scanning transmission electron microscope (FE-SEM/STEM) for the central Texas academic science and engineering community. This instrument will significantly impact several areas of research ranging from soft tissue applications in drug delivery systems, on through catalysis, to probing the cell walls of diatoms and cement-based materials and analyzing the nanostructure of fuel cell materials. Furthermore it will fill a crucial gap in characterizing materials with nanoscopic dimensions using a work-horse, user friendly instrument that draws strong demand across engineering, materials science and natural science disciplines.A scanning electron microscope/scanning transmission electron microscope is a powerful tool for imaging a wide range of materials ranging from nanoparticles to polymers and films. The instrument provides topological and compositional information of these materials. It is an essential analytical tool in research on the properties and behavior of such materials. This is a consortium award that involves 11 research groups as major users and 46 research groups as minor users at UT-Austin from 14 different departments affiliated with the Texas Materials Institute (TMI) and the Center for Nano and Molecular Science and Technology (CNM), as well as, outside users at the Texas Memorial Museum, and the UT Health Science Center at Houston. UT-Austin will also enable access to smaller Texas universities in the nearby area. The instrument will be used by BS, MS, PhD and post doctoral students in their research training, thus preparing them for careers in science and engineering with state of the art technology.
