MRI: Acquisition of a Scanning X-ray Photoelectron Spectrometer Microprobe (sXPS-u) for Research and Education at the University of Nevada, Reno

该合同支持内华达大学里诺分校（UNR）的扫描x射线光电子光谱仪微探针（sXPS-u）的采购。sXPS-u系统允许表征各种材料，并为研究人员提供材料的化学组成。这样的系统对于诸如冶金、腐蚀、航空航天、纳米材料、催化、采矿、汽车、人类学、地质学、电子和先进制造业等一系列主题的科学进步至关重要，特别强调能源产生和存储主题，如地热、核能、太阳能和电池技术。sXPS-u仪器用于培训数百名不同水平的学生，以帮助培养下一代工程师，科学家和发明家。来自UNR、其他学术机构和国家实验室的大量教师和科学家可以使用spps -u系统20%的时间。来自行业的用户，从跨国公司到小型企业和UNR孵化器中的初创企业，通过内华达州材料表征（MCNV）分享30%的时间，内华达州材料表征（MCNV）是UNR致力于为行业提供材料表征服务的实体。该工具在若干课程中使用，以加强开发计划署的教育和培训。具体来说，正在开发专门的课程模块，向学生展示在表面分析中使用sXPS-u。在科学和工程领域，女性和未被充分代表的少数族裔是扩大她们参与和帮助内华达州发展多元化劳动力的特别目标。XPS提供了化学形态（成键或氧化态）、分子成键信息、带隙和价带性质。获得sXPS-u系统大大有利于下列联合国研究计划署核心资助的研究项目（占总使用量的50%）：开发用于能源效率、轻型车辆和下一代发电厂的新型金属材料，了解极端环境下金属的腐蚀，开发先进电池，改进电催化，开发动态窗口，优化废旧核燃料的后处理/管理，理解纳米结构的电化学，以及纳米-水-食物-能源关系的项目。该项目由材料研究部和促进竞争研究的既定计划（EPSCoR）共同资助。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This award supports the acquisition of a Scanning X-ray Photoelectron Spectrometer Microprobe (sXPS-u) at the University of Nevada, Reno (UNR). The sXPS-u system allows characterization of various materials and provides researchers with the chemical makeup of materials. Such a system is critical for scientific advances in a range of topics such as metallurgy, corrosion, aerospace, nanomaterials, catalysis, mining, automotive, anthropology, geology, electronics and advanced manufacturing, with a special emphasis on energy generation and storage topics such as geothermal, nuclear, solar, and battery technology. The sXPS-u instrument is used to train hundreds of students at various levels to help prepare the next generation engineers, scientists, and inventors. A large number of faculty and scientists from UNR, other academic institutions and national laboratories have access to 20% of the time on the sXPS-u system. Users from industry, ranging from multinational corporations to small businesses and startups in the UNR incubator share 30% of the time through the Materials Characterization Nevada (MCNV), an UNR entity dedicated to providing materials characterization services to industry. The instrument is used in several courses to enhance education and training at UNR. Specifically, dedicated course modules are being developed to demonstrate the use of sXPS-u in surface analysis to students. Women and underrepresented minorities in science and engineering are particularly targeted to broaden their participation and help develop a diverse workforce for Nevada. XPS provides both the chemical speciation (bonding or oxidation state), the molecular bonding information, bandgap and valence band properties. The acquisition of the sXPS-u system greatly benefits the following core-funded research projects at UNR (50% of total usage): development of new metallic materials for energy efficiency, lightweight vehicles, and next-generation power plants, understanding corrosion of metals in extreme environments, development of advanced batteries, improving electrocatalysis, developing dynamic windows, optimization of reprocessing/management of used nuclear fuel, comprehending electrochemistry of nanostructures, and projects at the nano-water-food-energy nexus. This project is jointly funded by the Division of Materials Research, and the Established Program to Stimulate Competitive Research (EPSCoR).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.
