With this award from the Major Research Instrumentation (MRI) and Chemistry Research Instrumentation and Facilities (CRIF) Programs, Professor L. Robert Baker from Ohio State University (OSU) and colleagues Umit Ozkan, Gerald Frankel, Anne Co and David Cole have acquired an X-ray photoelectron spectrometer (XPS) which operates at near ambient pressures instead of the more usual high-vacuum operation of standard XPS. These instruments use X-rays to eject electrons from surfaces. The electrons are detected and analyzed to identify the elemental and chemical composition of such surfaces. This surface-sensitive probe is used to study electronic devices, batteries, fuel cells, sensors, corrosion, materials degradation, catalytic reactions and geochemistry. It serves the need in academia and industry to probe chemical details of solid and liquid surfaces under chemically-relevant conditions. The instrument is used by researchers at OSU and about a dozen regional institutions including industries and institutions serving underrepresented minorities in STEM fields. This participation generates a significant regional impact. Undergraduate and graduate students are trained to use the instrument in research projects, laboratory coursework and workshops. The award is aimed at enhancing research and education at all levels at OSU, especially in areas such as: (a) studying solid electrolyte interphase and interfacial ion solvation, (b) probing catalysis, electrocatalysis, and solid oxide fuel cells, (c) analyzing materials degradation and corrosion, and (d) studying earth science and geochemistry.

俄亥俄州立大学 (OSU) 的 L. Robert Baker 教授及其同事 Umit Ozkan、Gerald Frankel、Anne Co 和 David Cole 获得了主要研究仪器 (MRI) 和化学研究仪器和设施 (CRIF) 项目颁发的这一奖项，获得了一台 X 射线光电子能谱仪 (XPS)，它在接近环境压力下运行，而不是在标准 XPS 的更常见的高真空操作下运行。这些仪器使用 X 射线从表面喷射电子。检测和分析电子以识别此类表面的元素和化学成分。这种表面敏感探针用于研究电子设备、电池、燃料电池、传感器、腐蚀、材料降解、催化反应和地球化学。它满足学术界和工业界在化学相关条件下探测固体和液体表面的化学细节的需求。该工具由俄勒冈州立大学和大约十几个地区机构的研究人员使用，其中包括为 STEM 领域代表性不足的少数群体提供服务的行业和机构。这种参与产生了重大的区域影响。本科生和研究生接受过在研究项目、实验室课程和研讨会中使用该仪器的培训。该奖项旨在加强俄勒冈州立大学各级的研究和教育，特别是在以下领域：(a) 研究固体电解质界面和界面离子溶剂化，(b) 探测催化、电催化和固体氧化物燃料电池，(c) 分析材料降解和腐蚀，(d) 研究地球科学和地球化学。
