MRI: Acquisition of a Transmission Electron Microscope for Multidisciplinary Research

该奖项是根据2009年《美国复苏和再投资法案》(Public Law 111-5)资助的。在主要研究仪器(MRI)项目的资助下，坦普尔大学化学系将获得一台用于跨学科纳米材料研究的透射电子显微镜(TEM)。将从这项收购中受益的研究活动的具体例子包括：研究土壤和水系统中纳米颗粒的相变；组成聚合物电解质膜(PEM)燃料电池的纳米结构；用于光学应用的功能化纳米颗粒；用于肿瘤热疗的功能化顺磁纳米颗粒；以及由于同型半胱氨酸水平升高而导致的生物组织和细胞的形态变化。透射式电子显微镜是一种广泛使用的技术，它提供由穿过样品的电子束相互作用形成的薄样品的图像。瞬变显微镜比光学显微镜具有更高的分辨率。它被用于材料研究和生物等领域，在高分辨率下检测这些材料的结构和性能。收购TEM将有利于化学、生物、地球和环境科学、物理、机械、土木和环境工程、放射学和医学药理学等系的本科生和研究生的研究和培训。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).With this award from the Major Research Instrumentation (MRI) program, the Department of Chemistry at Temple University will acquire a Transmission Electron Microscope (TEM) for use in interdisciplinary nanomaterials research. Specific examples of research activities that will benefit from this acquisition include the study of phase transformation of nanoparticulate in soil and aquatic systems; nanostructures that make up polymer electrolyte membrane (PEM) fuel cells; functionalized nanoparticles for optical applications; functionalized paramagnetic nanoparticles for hyperthermia treatment of tumors; and morphological changes of biological tissues and cells that result from elevated levels of homocysteine.Transmission electron microscopy is a widely used technique that provides an image of a thin sample formed from the interaction of a beam of electrons transmitted through the specimen. A TEM provides higher resolution than optical microscopes. It is used in materials research and biological fields among others to examine the structure and properties of these materials under high resolution. The TEM acquisition will benefit research and the training of undergraduate and graduate students in the Departments of Chemistry, Biology, Earth and Environmental Science, Physics, Mechanical, Civil and Environmental Engineering, Radiology, and Pharmacology in Medicine.
