MRI: Acquisition of a Low-Voltage Transmission Electron Microscope (TEM) to Enable Chemistry Research and Training at Central Pennsylvania Undergraduate Institutions

该奖项由主要研究仪器（MRI）和化学研究仪器（CRIF）计划支持。有了它，马歇尔学院的富兰克林教授凯瑟琳普拉斯和同事克劳德·约德和詹妮弗·莫福德获得了透射电子显微镜（TEM）。 TEM发射一束电子穿过一层薄薄的材料。 电子束与物质相互作用产生视觉图像，类似于显微镜。这些图像对于研究材料的化学性质非常重要。它们揭示了结构的细节，例如纳米颗粒或蛋白质的大小和形状。 这些信息有助于研究人员了解材料的特性并加以改进。这一收购加强了本科生在研究方面的培训。 该仪器主要用于四个本科院校，富兰克林和马歇尔学院，奥尔布赖特学院，乌尔辛学院和米勒斯维尔大学。购买这种电子显微镜旨在加强研究，特别是在以下领域：（a）合成纳米材料，用于研究与分子或细胞接触的纳米颗粒的性质，（B）用于调节阳离子交换的等离子体半导体纳米颗粒，（c）通过合成铁-钼-硫化物纳米颗粒来研究钼在海洋沉积物中的积累，（d）磷灰石材料中的离子取代，（e）金属纳米颗粒作为碳纳米管生长的催化剂，（f）碳纳米管和氧化石墨烯作为运输四环素抗生素的载体，（g）等离子体金属纳米颗粒和（h）模块蛋白质以及它们如何在细胞内移动。

This award is supported by the Major Research Instrumentation (MRI) and the Chemistry Research Instrumentation (CRIF) Programs. With it, Professor Katherine Plass from Franklin & Marshall College and colleagues Claude Yoder and Jennifer Morford acquire a transmission electron microscope (TEM). A TEM sends a beam of electrons through a thin layer of material. The electron beam interacts with the substance to produce a visual image, similar to a microscope. These images are important for research on the chemical properties of materials. They reveal details of the structure, such as size and shape of a nanoparticle or a protein. This information helps researchers understand the material's properties and improve them. The acquisition enhances the training of undergraduates in research. The instrument is used at four primarily undergraduate institutions, Franklin and Marshall College, Albright College, Ursinus College and Millersville University. The acquisition of this electron microscope is aimed at enhancing research, especially in areas such as: (a) the synthesis of nanomaterials for the study of the properties of nanoparticles interfacing with molecules or cells, (b) plasmonic semiconducting nanoparticles used to modulate cation exchange, (c) studies of molybdenum accumulation in marine sediments by synthesizing iron-molybdenum-sulfide nanoparticles, (d) ion substitution in apatite materials, (e) metal nanoparticles as catalysts for carbon nanofiber growth, (f) carbon nanotubes and graphene oxide as vectors for transporting tetracycline antibiotics, (g) plasmonic metal nanoparticles and (h) modular proteins and how they move within cells.
