Acquisition of Scanning Electron Microscope for Introductory/Advanced Course Work and Faculty/Undergraduate Research: Biology, Geological Sciences, Anthropology

获得扫描电子显微镜用于入门/高级课程作业和教师/本科生研究：生物学，地质科学，人类学。仪器设备：生物学系的扫描电子显微镜（SEM）已经使用了15年。最近的故障（扫描/物镜线圈破裂）和无法获得更换部件或修理的可能性使显微镜无法操作。生物和地质科学领域的主要用户建议更换不能使用的仪器，并在新仪器中加入能量色散x射线（EDX）分析系统。Geneseo主要是一所本科院校，致力于教师和学生的研究。提议的扫描电镜将在几门课程中使用，作为指导研究，本科论文的主要工具，以及作为教师和本科生研究项目的研究工具。利用扫描电镜的课程包括：普通生物学实验室（生物118；实验室演示），显微镜技术（生物378），生物技术：电子显微镜（生物390）和无脊椎古生物学（GSci 361）。在这些课程中，每年有25-75名学生被介绍或接受仪器操作方面的培训。指导研究（Biol 382, 399, Gsci 399, Anth 399）和其他学生研究项目将占学生使用和培训的很大一部分。在这些调查中，学生在适当的监督下使用SEM来追求个人或项目的研究目标。（自从去年扫描电镜崩溃以来，在地质学课程或项目中有12名学生有理由使用扫描电镜进行微化石和沉积颗粒或结构研究。）Geneseo的教师研究包括几个利用电子显微镜的领域；为了获得外部资金和继续进行研究，需要采购一种新的仪器。教师的教学和研究包括：古近系灵长类动物进化（Anemone）、寄生虫学（Bandoni）、斑马贻贝幼虫形态学（Bosch）、绿藻鞭毛装置（Hoops）、微古生物学和黑色页岩研究（Over）、植物-细菌关系（Simon）和孢粉学（Spear）。EDX系统将应用于鸟类的磁传感（Beason）、沉积物中的古磁结构（Brennan）、膨土和洞穴衬里表征（Over）以及细菌生态系统（Simon）等研究。此外，将增加SEM-EDX的研究潜力，以纳入更广泛的研究。对新型扫描电镜的资助将导致对高分辨率、高对比度显微镜必不可少的生物和环境的持续研究。该工具将成为学生和教师研究的一个组成部分，并作为鼓励代表性不足的群体从事科学和工程职业的工具。6个主要用户目前有研究经费，4个项目与利用SEM的研究直接相关；所有主要用户都有正在审查或准备的建议书，将利用电子扫描管理系统和/或电子数据处理系统。

Acquisition of scanning electron microscope for introductory/advanced course work and faculty/undergraduate research: Biology, Geological Sciences, Anthropology. Instrumentation: The scanning electron microscope (SEM) housed in the Department of Biology has been in service for fifteen years. Recent breakdown (cracked scanning/objective coils) and unavailability of replacement parts or possibility of repair has made the microscope inoperable. The major users in Biology and Geological Sciences propose to replace the inoperable instrument and incorporate an Energy Dispersive X-Ray (EDX) analysis system in a new instrument. Research and Training Geneseo is a primarily undergraduate institution with a strong commitment to faculty and student research. The proposed SEM would be utilized in several courses, as a primary instrument in directed studies, undergraduate theses, and as a research instrument for faculty and undergraduate research projects. Courses that utilize the SEM included: General Biology Laboratory (Biol 118; laboratory demonstration), Microscope Techniques (Biol 378), Biological Techniques: Electron Microscopy (Biol 390), and Invertebrate Paleontology (GSci 361). In these courses 25-75 students are introduced annually and or trained in operation of the instrument. Directed studies (Biol 382, 399, Gsci 399, Anth 399) and other student research projects will comprise a significant portion of student use and training. In these investigations students under an appropriate level of supervision use the SEM to pursue individual or project research goals. (In the last year since the SEM breakdown twelve students in geology course or projects have had reason to use an SEM for microfossil and sedimentary particle or fabric studies.) Faculty research at Geneseo encompasses several fields that utilize electron microscopy; procurement of a new instrument is required for attainment of external funds and continued research. Faculty teaching and rese arch include: Paleogene primate evolution (Anemone), parasitology (Bandoni), Zebra mussel larva morphology (Bosch), flagellar apparatus of green algae (Hoops), micropaleontology and black shale studies (Over), plant-bacteria relations (Simon), and palynology (Spear). An EDX system will be applied in research involving magnetic sensing in birds (Beason), paleomagnetic fabric in sediments (Brennan), bentonite and burrow lining characterization (Over), and bacterial ecosystems (Simon). In addition the research potential of the SEM-EDX will be increased to incorporate a broader range of studies. Funding for a new SEM will lead to continued study of organisms and environments where high resolution, high contrast microscopy is essential. The instrument will be an integral part of student and faculty research and serve as a tool for encouraging under-represented groups to pursue careers in science and engineering. Six of the major users currently have research funding, four projects are directly related to studies that utilize the SEM; all major users have proposals under review or in preparation that will utilize the SEM an/or EDX system.
