A New Scanning Electron Microscope for Carleton College Will Study Big Scientific Questions and Train Young ScientistsThis award will be used to purchase a new scanning electron microscope (SEM) at Carleton College. The faculty at Carleton and nearby St. Olaf college will use the SEM to continue excellent training and education to the next generation of scientists with classes and research. The new SEM will be used to address scientific problems in the Earth sciences including the geologic history of western North America and Alaska, studies of ancient climates, and large faults similar to the San Andreas Fault in California. This equipment will also help answer questions in chemistry that will help to produce useful chemical products and will help describe air pollution. In addition, the instrument will be used to train undergraduate students in state-of-the-art analytical techniques.Carleton College will use this Major Research Instrumentation award to acquire a new variable pressure scanning electron microscope (SEM), color cathodoluminescence (CL) detector, and electron-backscatter diffraction (EBSD) system. This new facility will allow the faculty at Carleton and nearby St. Olaf College to continue to offer high-quality and effective training of the next generation of scientists through authentic research activities in courses and through advanced undergraduate research including senior thesis research projects. The capabilities of the new SEM facility will help address outstanding scientific questions in the Earth sciences including the plate tectonic history of western North America and Alaska, the reconstruction of past climate and seawater properties, and the behavior of large scale faults similar to the San Andreas Fault in California. This equipment will also help answer fundamental questions in chemistry that have implications for the use of inexpensive mixed metal oxide thin films as catalysts for the photoelectrochemical production of valuable chemical products, and for the characterization of particulate matter in air pollution associated with cooking in Ethiopia and other developing countries. The acquisition of the new SEM will enhance research and research training at Carleton and St. Olaf. It will improve the research capacity of at least seven faculty members, four departments and two colleges, 15 courses, and about 700 students. The SEM will occupy a newly renovated space in Carleton`s new Science Complex. One of the primary goals for the Science Complex is to bring together faculty and students from a variety of disciplines into collaborative spaces where our disciplinary and multidisciplinary research efforts are more visible to one another. The new SEM will foster research collaboration between Carleton and St. Olaf. The instrument will be very important to the new and growing Environmental Studies Department at St. Olaf, which made three new tenure-track hires in 2017. Because St. Olaf has no formal geology department, collaboration with Carleton offers an extended community of St. Olaf faculty and students interested in the Earth sciences. In addition, having a modern SEM facility available to support new faculty at St. Olaf will also allow them to build course-based research activities into their growing Environmental Studies major.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.

卡尔顿学院的新扫描电子显微镜将学习大科学问题和训练年轻科学家，这将用于在卡尔顿学院购买新的扫描电子显微镜（SEM）。卡尔顿和附近的圣奥拉夫学院的教职员工将使用SEM继续对下一代科学家进行课程和研究的良好培训和教育。新的SEM将用于解决地球科学中的科学问题，包括西部北美和阿拉斯加的地质历史，对古代气候的研究以及类似于加利福尼亚州圣安德烈亚斯断层的大缺点。该设备还将有助于回答化学问题，这些问题将有助于生产有用的化学产品，并有助于描述空气污染。此外，该仪器将用于培训本科生的最先进的分析技术。卡尔顿学院将使用该重大研究仪器奖获得新的可变压力扫描电子显微镜（SEM），颜色降压发光（CL）探测器（CL）探测器和电子 - 贝克斯克斯特衍射（EBSD）系统。这个新设施将使卡尔顿和附近的圣奥拉夫学院的教师通过课程中的真实研究活动以及包括高级论文研究项目（高级论文研究项目）继续为下一代科学家提供高质量和有效的科学家培训。新的SEM设施的能力将有助于解决地球科学中的杰出科学问题，包括西部北美和阿拉斯加的板块构造历史，过去气候和海水物业的重建以及与加利福尼亚州圣安德烈亚斯断层类似的大规模断层的行为。该设备还将有助于回答化学中的基本问题，这些问题对使用廉价的混合金属氧化物薄膜作为催化剂的光电化学生产以及对埃塞俄比亚和其他发展中国家烹饪相关的空气污染的表征。新SEM的获取将在Carleton和St. Olaf增强研究和研究培训。它将提高至少七名教职员工，四个学院和两所大学，15个课程和约700名学生的研究能力。 SEM将在卡尔顿的新科学综合体中占据新装修的空间。科学综合体的主要目标之一是将各种学科的教职员工和学生聚集到协作空间中，在这些空间中，我们的学科和多学科研究工作更加可见。新的SEM将促进卡尔顿和圣奥拉夫之间的研究合作。该工具对于圣奥拉夫的新的和不断发展的环境研究部将非常重要，该部门在2017年创造了三名新的终身制员工。由于圣奥拉夫没有正式的地质部门，因此与卡尔顿的合作提供了圣奥拉夫教职员工和对地球科学感兴趣的学生的扩展社区。此外，拥有现代的SEM设施来支持圣奥拉夫的新教师还将使他们能够在其不断增长的环境研究专业的专业中建立基于课程的研究活动。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子的评估来支持的，并具有更广泛的影响。
