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.

该奖项是根据 2009 年美国复苏和再投资法案（公法 111-5）提供资金的。通过重大研究仪器 (MRI) 计划的这一奖项，天普大学化学系将获得一台透射电子显微镜 (TEM)，用于跨学科纳米材料研究。 将从此次收购中受益的研究活动的具体例子包括土壤和水生系统中纳米颗粒相变的研究； 构成聚合物电解质膜（PEM）燃料电池的纳米结构； 用于光学应用的功能化纳米粒子； 用于肿瘤热疗的功能化顺磁纳米粒子； 同型半胱氨酸水平升高导致生物组织和细胞的形态变化。透射电子显微镜是一种广泛使用的技术，可提供通过样品传输的电子束相互作用形成的薄样品的图像。 TEM 提供比光学显微镜更高的分辨率。 它用于材料研究和生物领域等，以高分辨率检查这些材料的结构和性能。 TEM 的收购将有利于化学、生物学、地球与环境科学、物理、机械、土木与环境工程、放射学和医学药理学系本科生和研究生的研究和培训。
