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.

凭借主要研究工具（MRI）和化学研究工具和设施（CRIF）计划的奖项，俄亥俄州立大学（OSU）的L. Robert Baker教授和同事Umit Ozkan，Gerald Frankel，Anne Co和David Cole获得了一份X射线光电子光谱仪（XPS）在近乎环境压力下进行操作，而不是标准XPS的更常见的高空操作。这些仪器使用X射线从表面弹出电子。检测和分析电子以识别此类表面的元素和化学组成。该表面敏感的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。它满足了学术界和行业的需求，以探测与化学相关条件下固体和液体表面的化学细节。 OSU的研究人员和大约十几个地区机构使用了该工具，包括在STEM领域提供代表性不足的少数民族的行业和机构。该参与产生了重大的区域影响。在研究项目，实验室课程和讲习班中，对本科生和研究生进行了培训。该奖项旨在增强OSU的各个级别的研究和教育，尤其是在：（a）研究固体电解质相间和界面离子溶剂化的领域，（b）探测催化，电催化和氧化物燃料电池，（c）分析材料降解和腐蚀，以及（d）研究地球科学和地球化学。
