项目摘要

An integrated Scanning Electron Microscope (SEM) with multiple sensor capability and a carbon coater for sample preparation will be acquired at Sonoma State University (SSU). This SEM system will 1) increase the quality and diversity of data that will be collected and analyzed, 2) increase speed of data collection facilitating the faculty’s ability to establish collaborative relationships, 3) support existing curricular infrastructure and training of the next generation of scientists using modern technology and data acquisition techniques, 4) increase student diversity within the STEM disciplines, 5) facilitate and maintain industry partnerships and internship opportunities for students, and 6) foster an academically diverse user-base for electron microscopy at SSU. The proposed SEM and associated detectors have the potential to significantly impact 15 courses at SSU and approximately 500 student per year. In addition to the classroom environment, many of our science majors become involved in independent research as a capstone experience, and many of those students utilize the SEM facilities as part of their research. SSU is committed to educating persons of all backgrounds and is dedicated to increasing gender and ethnic diversity in the sciences. SSU is a federally recognized Hispanic-Serving Institution with an undergraduate population that is 33% Hispanic. This population is historically underrepresented in the STEM disciplines; however, having access to hands-on research opportunities with state-of-the-art equipment has proven to be an effective technique for recruiting underrepresented populations into STEM.The acquisition of the proposed SEM microanalysis system will greatly increase the quality and scope of the research agendas of the five investigators from the Geology, Physics, and Chemistry Departments, as well as faculty members from other departments at SSU (e.g., Biology, Anthropology, Geography, and Engineering Sciences). Specific research questions facilitated by this instrument include: 1) the long-term history of fault systems, 2) mechanisms of mountain building, 3) plate tectonic reconstructions, 4) self-assembly of nano-materials, 5) nano-sensor development, and 6) investigation into the properties of magnetic systems exhibiting spin frustration, which can be used to create all-magnetic computer architectures. This instrument expands the type of scientific questions that we can address and facilitates cross-disciplinary research within the university and with our collaborating institutions. The current system at SSU cannot be upgraded and has become unreliable/non-functioning in the past few years; it is frequently out of commission during repairs and no longer produces the quality of data necessary for conducting research. In addition to standard secondary electron imaging capabilities, Energy-Dispersive X-ray Spectrometry (EDS), Electron Backscatter Diffraction (EBSD), and Cathodoluminescence (CL) imaging capabilities are critical for SSU faculty research activities. Our research needs outstrip this SEM system because we need: 1) a faster, more sensitive SEM/EBSD system that can automate data acquisition schemes for large-area mapping, 2) an SEM/EDS system with increased resolution to resolve elemental distributions of nano-structures, 3) an integrated CL detector for imaging zoning in crystals associated with detrital zircon geochronology analyses, 4) a larger chamber for the analysis of geological materials, 5) integrated safety features to avoid sample-instrument collisions when training novice users, 6) an upgradable system that integrates with the continually evolving hardware and software industry and 7) to increase reliability for more dependable integration into curricular and research activities.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
索诺马州立大学(SSU)将购置一台具有多传感器功能的集成扫描电子显微镜(SEM)和一台用于样品制备的碳涂层器。该SEM系统将1)提高将收集和分析的数据的质量和多样性,2)提高数据收集的速度,促进教师建立合作关系的能力,3)支持现有的课程基础设施和使用现代技术和数据采集技术的下一代科学家的培训,4)增加STEM学科内的学生多样性,5)促进和维护行业合作伙伴关系和实习机会的学生,和6)促进学术多元化的用户群在SSU电子显微镜。拟议的SEM和相关的探测器有可能显着影响15门课程在SSU和每年约500名学生。除了课堂环境,我们的许多科学专业成为参与独立研究作为顶点的经验,和许多这些学生利用SEM设施作为他们的研究的一部分。SSU致力于教育各种背景的人,并致力于增加科学中的性别和种族多样性。SSU是联邦政府认可的西班牙裔服务机构,本科生人口中有33%是西班牙裔。这一群体在STEM学科中的代表性历来不足;然而,使用最先进的设备获得实践研究机会已被证明是招募代表性不足的人群进入STEM的有效技术。拟议的SEM微量分析系统的收购将大大提高地质,物理和化学系五名研究人员的研究议程的质量和范围,以及来自SSU其他部门的教职员工(例如,生物学、人类学、地理学和工程科学)。该仪器促进的具体研究问题包括:1)断层系统的长期历史,2)造山机制,3)板块构造重建,4)纳米材料的自组装,5)纳米传感器的开发,以及6)对表现出自旋挫折的磁性系统的性质的调查,这可用于创建全磁计算机架构。该工具扩展了我们可以解决的科学问题的类型,并促进了大学内和我们的合作机构的跨学科研究。SSU目前的系统无法升级,在过去几年中变得不可靠/无法运作;在维修期间经常无法使用,不再产生进行研究所需的高质量数据。除了标准的二次电子成像能力,能量色散X射线光谱仪(EDS),电子背散射衍射(EBSD)和阴极发光(CL)成像能力是至关重要的SSU教师的研究活动。我们的研究需要超越这个SEM系统,因为我们需要:1)更快、更灵敏的SEM/EBSD系统,其可以自动化用于大面积绘图的数据采集方案,2)具有提高的分辨率以解析纳米结构的元素分布的SEM/EDS系统,3)集成的CL检测器,其用于对与碎屑锆石地质年代学分析相关的晶体中的分区进行成像,4)用于分析地质材料的较大腔室,5)当训练新手用户时避免样品-仪器碰撞的集成安全特征,6)一个与不断发展的硬件和软件行业集成的可扩展系统,以及7)该奖项反映了NSF的法定使命,并被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准。
