MRI:Acquisition of an UV-Vis and X-ray Photoelectron Spectroscopy (UPS/XPS) for Research and Education in Electronics and Advanced Materials

该项目的目标是通过购买最先进的紫外线和X射线光电子能谱(UPS/XPS)仪器，推动韦恩州立大学(WSU)在电子学、传感器、纳米材料、催化和能源领域的研究和教育。特别是，拟议的UPS/XPS将被用作几个项目的启动工具，这些项目迫切需要拟议的仪器以高灵敏度和空间分辨率表征材料表面的物理和化学特征。UPS/XPS将显著提高西澳州立大学在广泛领域的研究质量和生产率。收购UPS/XPS将为WSU在设备、材料、生物医学和能源研究方面提供协同机会。还将提高本科生和研究生的科研培养质量。总而言之，这项拟议的UPS/XPS仪器预计将影响来自20个研究小组的100多名用户。对于当地工业来说，它将成为先进电池制造的资源，对密歇根州东南部的经济增长至关重要。WSU将利用现有的科学、技术、工程和数学(STEM)项目招收来自少数族裔、女性和残疾学生等代表性不足群体的学生。UPS/XPS是了解材料合成以及物理和/或化学处理中的表面化学的独特而宝贵的工具。它是研究新材料的功函数和价带，量化样品表面顶部2-10 nm内的化学元素和原子成键的重要工具。该仪器具有4种独特的功能，包括(1)化学测量中的灵敏定量，(2)扫描XPS微探针分析，(3)紫外光电子能谱，和(4)微区深度剖析。因此，收购UPS/XPS将显著提高华盛顿州立大学正在进行的研究的质量和生产率，研究领域广泛，从下一代电子产品的开发(例如，石墨烯以外的2D材料、原子层沉积)到生物医学应用(例如，生物传感、护理设备)，再到能源应用(例如，催化、燃料电池、锂离子电池、绿色化学和可持续性)。我们的长期目标是加强华盛顿州立大学的研究设施，以支持研究和教育，向密歇根州东南部的科学界提供最先进的表征设备，并通过提供实践学习体验，加强大底特律地区研究生、本科生和高中生的研究和教育/培训。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

The objective of this project is to advance research and education in the areas of electronics, sensors, nanomaterials, catalysis, and energy at Wayne State University (WSU) through the acquisition of a state-of-the-art ultraviolet and X-ray photoelectron spectroscopy (UPS/XPS) instrument. Particularly, the proposed UPS/XPS will be used as an enabling tool for several projects which urgently need the capability of the proposed instrument to characterize the physics and chemistry of material surfaces with high sensitivity and spatial resolution. UPS/XPS will significantly improve the quality and productivity of research at WSU in a broad range of areas. The acquisition of UPS/XPS will permit synergistic opportunities for device, material, biomedical, and energy research at WSU. It will also enhance the quality of research training of undergraduates and graduate students. Together, this proposed UPS/XPS instrument is expected to impact more than 100 users from 20 research groups. For local industry, it will serve as a resource for advanced battery manufacturing critical to the economic growth of southeastern Michigan. Students from underrepresented groups including minorities, women, and students with disabilities will be recruited using existing science, technology, engineering, and mathematics (STEM) programs at WSU. UPS/XPS is a unique and invaluable tool to understand surface chemistry in material synthesis as well as physical and/or chemical treatments. It is an essential tool to study the work function and valence band of new materials and to quantify chemical elements and the bonding of atoms within the top 2 nm to 10 nm of the sample surface. The proposed instrument enables 4 unique capabilities, including (1) sensitive quantification in chemical measurements, (2) scanning XPS microprobe analysis, (3) UV Photoelectron Spectroscopy, and (4) micro area depth profiling. Therefore, the acquisition of UPS/XPS will significantly improve the quality and productivity of on-going research at WSU in a broad range of areas from the development of next-generation electronics (e.g., 2D materials beyond graphene, atomic layer deposition) to biomedical applications (e.g., biosensing, point-of-care devices) and to energy applications (e.g., catalysis, fuel cells, lithium ion batteries, green chemistry, and sustainability). Our long-term goals are to strengthen WSU research facilities in order to support research and education, to offer state-of-the-art characterization equipment to the scientific community of southeastern Michigan, and to enhance research and education/training of graduate, undergraduate, and high-school students in the greater Detroit area by offering hands-on learning experience.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.
