项目摘要
Technical abstractThe interdisciplinary multi-user Electron Microscopy Facility at Trinity College seeks funds to acquire a modern analytical variable-pressure Scanning Electron Microscope (SEM) to serve as a critical research tool for imaging and elemental analysis of materials and life science specimens from across the sciences. The requested SEM will play an important and complementary role in Trinity?s existing EM Facility which currently comprises two Transmission Electron Microscopes including an analytical TEM/(S)TEM, a wide range of specimen preparation tools, and a failing 24-year-old SEM with diminished functionality. The new SEM will serve researchers from diverse fields working on projects that include the study of placental morphology in viviparous reptiles (Biology), microparticulates in lake sediments (Environmental Science), archeological artifacts (Chemistry and Classics), nanowire characterization (Physics), and soft condensed matter (Engineering).The requested variable-pressure SEM with X-ray Energy Dispersive Spectroscopy and Micro X-ray Fluorescence will meet the research and pedagogical needs of the sciences at Trinity and facilitate greater exposure of scientific principles and advanced scientific instrumentation to more faculty, students and collaborators. It will be used by faculty and undergraduates in the sciences and in other disciplines for research and research training. It will support education by its use in undergraduate courses and laboratory modules tailored to each science department or program and the inclusion of undergraduates in faculty research. The ease of use and broad analytical capabilities of this instrument will enable examination of specimens ranging from geological samples to biological tissues, from archeological artifacts to fabricated nanowires and foams, with a high degree of spatial resolution in both imaging and analytical applications. It will support increased numbers of users and types of scientific investigation by Trinity researchers in Biology, Environmental Science, Chemistry, Neuroscience, Engineering and Physics, by collaborators in neighboring institutions, and in established outreach programs that include undergraduate and graduate students as well as high school and grammar school students and their teachers.Non-technical abstractThe interdisciplinary multi-user Electron Microscopy Facility at Trinity College seeks funds to acquire a modern analytical variable-pressure Scanning Electron Microscope (SEM) to serve as a critical research tool for imaging and elemental analysis of materials and life science specimens from across the sciences.The requested SEM will meet the research and pedagogical needs of the sciences at Trinity and facilitate greater exposure of scientific principles and advanced scientific instrumentation to more faculty, students and collaborators. This SEM is an advanced scientific tool which enables high-resolution imaging of structures far too small to be visualized by the unaided eye or even with a light microscope. Various detectors make possible complex and complementary compositional analysis of a wide range of sample types. Insights gathered with this instrument result in a better understanding of a material?s structural/functional relationships at the nano-level in studies involving biology (such as cells and organs, insects, plants, bacteria), the physical sciences (such as ceramics, semiconductors, plastics, rocks) and environmental science (such as sediments, atmospheric pollutants, and geologic history). Incorporating the SEM into both research and credited college courses exposes students across scientific disciplines and the humanities to the theoretical basis and applications of advanced scientific instrumentation, including proper scientific data collection and analysis and the presentation of research results.
技术摘要跨学科的多用户电子显微镜设施在Trinity学院寻求资金,以获得一个现代化的分析变压扫描电子显微镜(SEM),作为一个重要的研究工具,成像和元素分析的材料和生命科学标本从整个科学。所要求的SEM将在Trinity中发挥重要的补充作用?的现有EM设施,目前包括两个透射电子显微镜,包括分析TEM/(S)TEM,广泛的样品制备工具,和一个失败的24岁的SEM功能减弱。新的扫描电镜将为来自不同领域的研究人员提供服务,这些研究项目包括胎生爬行动物的胎盘形态学研究(生物学),湖泊沉积物中的微粒(环境科学),考古文物(化学和经典),纳米线表征(物理),和软凝聚态物质(工程)。所要求的变压扫描电镜与X射线能量色散光谱和微X-射线衍射。射线荧光将满足Trinity的科学研究和教学需求,并促进更多的教师,学生和合作者更多地接触科学原理和先进的科学仪器。它将被科学和其他学科的教师和本科生用于研究和研究培训。它将通过在本科课程和针对每个科学部门或计划的实验室模块中使用以及将本科生纳入教师研究来支持教育。该仪器的易用性和广泛的分析能力将使从地质样品到生物组织,从考古文物到制造的纳米线和泡沫的标本的检查,在成像和分析应用中具有高度的空间分辨率。它将支持生物学、环境科学、化学、神经科学、工程和物理学领域的Trinity研究人员,以及邻近机构的合作者,以及包括本科生和研究生以及高中和文法学校的学生和他们的老师在内的既定推广计划。Trinity学院的电子显微镜设施寻求资金,以获得现代分析变压扫描电子显微镜(SEM)作为一个关键的研究工具,用于对来自各个科学领域的材料和生命科学标本进行成像和元素分析。所要求的SEM将满足Trinity的科学研究和教学需求,促进更多的科学原理和先进的科学仪器接触更多的教师,学生和合作者。该扫描电镜是一种先进的科学工具,能够对肉眼甚至光学显微镜无法观察到的小结构进行高分辨率成像。各种检测器可以对各种样品类型进行复杂和互补的成分分析。用这种仪器收集的见解可以更好地理解材料?在涉及生物学(如细胞和器官、昆虫、植物、细菌)、物理科学(如陶瓷、半导体、塑料、岩石)和环境科学(如沉积物、大气污染物和地质历史)的研究中,纳米级的结构/功能关系。将SEM纳入研究和学分制大学课程,使学生跨越科学学科和人文学科,接触先进科学仪器的理论基础和应用,包括适当的科学数据收集和分析以及研究结果的展示。
