MRI: Acquisition of X-Ray Photoelectron Spectrometer for Discovering New Phenomena with In Situ Studies

通过主要研究仪器（MRI）和化学研究仪器和设施（CRIF）项目的奖励，俄亥俄州立大学（OSU）的L. Robert Baker教授和他的同事Umit Ozkan、Gerald Frankel、Anne Co和David Cole获得了一台x射线光电子能谱仪（XPS），它可以在接近环境压力的环境下工作，而不是更常见的标准XPS的高真空操作。这些仪器利用x射线从物体表面射出电子。电子被检测和分析，以确定这些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。它服务于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要。该仪器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，包括为STEM领域中代表性不足的少数民族服务的行业和机构。这种参与产生了重大的区域影响。本科生和研究生经过培训，可以在研究项目、实验课程和研讨会中使用该仪器。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相和界面离子溶剂化，(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，以及(d)研究地球科学和地球化学。

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.
