MRI: Acquisition of an X-ray Photoelectron Spectrometer for Characterization of Next-Generation Materials

这一重大研究仪器奖支持收购多用户XPS仪器，为加州大学戴维斯分校和大戴维斯地区的大量科学家提供服务。X射线光电子能谱(XPS)是一种表面敏感技术，可以提供有关材料、化学品和器件的化学成分的详细信息。因此，XPS测量数据对于理解和发展化学、物理、环境和工程研究中的材料是非常重要的。该仪器将对来自三个机构的超过33名教职员工的研究产生积极影响，并加强加州大学戴维斯分校的研究基础设施和教育推广。它将加快目前的进展，并使研究有新的方向。十多个项目将受到影响，包括可再生燃料的研究以及下一代电子产品的制造和优化。该仪器还将有助于发现更有效的太阳能转换设备，并将使化学工业中使用的催化剂性能的基础研究成为可能。这一仪器将对下一代科学家的教育和培训产生强大的影响。加州大学戴维斯分校的许多研究生和本科生课程都讲授与XPS相关的概念，注册这些课程的学生现在将有机会参与该仪器的实际动手实验。今年夏天，该仪器将向物理系和化学系NSF-REU(本科生研究经验)项目的本科生提供。将创建新的学习单元，并将其纳入高中暑期推广计划COSMOS(加州数学和科学暑期学校)。此外，该仪器将服务于作为MURPPS(少数族裔本科生参与自然科学)、CAMP(加州少数族裔参与数学、科学和工程联盟)和加州大学LEADS(加州大学弱势学生领导力计划)计划的经济困难和少数族裔学生进入校园的学生。为加强加州大学戴维斯分校和北加州萨克拉门托地区的材料科学研究和教育活动，提议购置一台X射线光电子能谱工具(XPS)。XPS工具将实现空间分辨的化学状态分析，探测分辨率从0.1%到1原子百分比，成像分辨率为1微米。收购XPS将为加州大学戴维斯分校的材料研究增加一个关键的新维度，该园区拥有成功应用和运营所需的专业知识和基础设施。XPS将影响177多名直接用户的材料研究和培训活动，这些用户正在研究和开发用于工业应用和可再生能源技术的新型下一代材料。它将促进加州大学戴维斯分校的校园研究基础设施和教育推广，加快当前的进展，并使材料研究的新方向成为可能。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。

This Major Research Instrumentation award supports the acquisition of a multi-user XPS instrument to serve a large community of scientists at the University of California Davis and in the greater Davis area. X-ray Photoemission Spectroscopy (XPS) is a surface sensitive technique that can provide detailed information about the chemical composition of materials, chemicals and devices. Therefore, data from XPS measurements is of great importance to the understanding and development of materials in chemical, physical, environmental, and engineering research. The instrument will positively impact the research of over 33 faculty members from three institutions and enhance the research infrastructure and educational outreach of UC Davis. It will accelerate current progress and enable new directions in research. More than ten projects will be affected, including research on renewable fuels and the manufacture and optimization of next generation electronics. The instrument will also aid the discovery of more efficient devices for solar energy conversion and it will enable fundamental research on the properties of catalysts used in chemical industry. This instrument will have a strong impact on the education and training of the next generation of scientists. Concepts related to XPS are taught in many graduate and undergraduate courses at UC Davis, and students enrolled in these classes will now have the opportunity to engage in hands-on actual experiments with the instrument. During the summer, the instrument will be made available to undergraduate students in the NSF-REU (Research Experiences for Undergraduates) program in Physics and Chemistry departments. New learning modules will be created and integrated into the high school summer outreach program COSMOS (California Summer School for Mathematics and Science). Additionally, the instrument will serve economically disadvantaged and minority students that come to campus as part of the MURPPS (minority undergraduate research participation in the physical sciences), CAMP (California alliance for minority participation in math, science and engineering), and UC LEADS (UC Leadership program for disadvantaged students) programs. Acquisition of an X-ray Photoemission Spectroscopy tool (XPS) is proposed to enhance materials science research and educational activities at UC Davis and in the Northern California Sacramento region. The XPS tool will enable spatially resolved chemical state analysis with a detection resolution from 0.1 to 1 atomic percent and an imaging resolution of 1 micron. Acquisition of an XPS will add a critical new dimension to materials research on the UC Davis campus, where expertise and infrastructure for the successful application and operation is available. XPS will impact the materials research and training activities of over 177 direct users who are working in research and development of novel, next-generation materials for industrial applications and renewable energy technologies. It will boost the campus research infrastructure and educational outreach of UC Davis, accelerating current progress and enabling new directions in materials research.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.
