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.

获取扫描电子显微镜，用于入门/高级 课程工作和教师/本科生研究：生物学， 地质科学，人类学。 仪器： 生物系的扫描电子显微镜（SEM）已经使用了15年。最近的故障（破裂的扫描/物镜线圈）和不可用的更换零件或维修的可能性，使显微镜无法操作。生物学和地质科学的主要用户建议更换无法操作的仪器，并在新仪器中加入能量色散X射线（EDX）分析系统。 研究训练 Geneseo是一所主要的本科院校，对教师和学生的研究有着坚定的承诺。拟议的SEM将被用于几门课程，作为指导研究，本科论文的主要工具，并作为教师和本科生研究项目的研究工具。利用SEM的课程包括：普通生物学实验室（Biol 118;实验室演示），显微镜技术（Biol 378），生物技术：电子显微镜（Biol 390）和无脊椎动物古生物学（GSci 361）。在这些课程中，每年有25-75名学生参加和/或接受仪器操作培训。定向研究（生物382，399，GSCI 399，ANTH 399）和其他学生研究项目将包括学生使用和培训的重要部分。在这些调查中，学生在适当的监督下使用SEM来追求个人或项目研究目标。(In自SEM故障以来的最后一年，12名地质学课程或项目的学生有理由使用SEM进行微体化石和沉积颗粒或结构研究。 Geneseo的教师研究包括利用电子显微镜的几个领域;需要采购新仪器以获得外部资金和继续研究。教师教学和研究包括：古近纪灵长类动物进化（海葵），寄生虫学（班多尼），斑马贻贝幼虫形态学（博世），绿色藻类的鞭毛装置（箍），微体古生物学和黑色页岩研究（过），植物-细菌关系（西蒙），和孢粉学（矛）。EDX系统将应用于鸟类磁感应（Beason）、沉积物中的古磁组构（Brennan）、膨润土和洞穴衬里表征（Over）以及细菌生态系统（Simon）的研究。此外，SEM-EDX的研究潜力将增加，以纳入更广泛的研究。 为新的SEM提供资金将导致对高分辨率，高对比度显微镜至关重要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。六个主要用户目前有研究资金，四个项目直接涉及利用SEM的研究;所有主要用户都有正在审查或准备的提案，将利用SEM和/或EDX系统。
