With support from the Major Research Instrumentation (MRI) Acquisition Program, the Department of Chemistry at the University of Texas, Austin will obtain an X-ray Photoelectron Spectrometer. This equipment will enhance research at a consortium that includes five other institutions: the University of Texas at San Antonio, Trinity University (in San Antonio), Southwestern University (in Georgetown), Texas State University (in San Marcos) and Baylor University (in Waco). The instrument will be used for a broad range of studies that focus on catalysis, electronic and photonic materials, environmental studies, fuel cell research, and biological materials. The X-ray photoelectron spectrometer enables researchers to probe the surface composition and the oxidation state of chemical elements in soft (organic) and hard (inorganic) materials. The instrument is configured to provide depth profiling and imaging capability. The imaging resolution will be approximately at the micrometer scale. This allows researchers to correlate chemical and physical properties with chemical composition. The instrument will be automated so that off-site users will be able to collect and analyze their data from their home institution at the completion of the sample run. The majority of the studies will be focused on energy-related studies, particularly catalysis, and environmental research. Undergraduate and graduate research students from the geographic area clustered around Austin will benefit from the training afforded by this remotely accessible instrument. UT (Austin) will introduce this technique into a new pilot program, first year undergraduate laboratory, that will have students engaged in research problems.

在主要研究仪器 (MRI) 采购计划的支持下，德克萨斯大学奥斯汀分校化学系将获得一台 X 射线光电子能谱仪。 该设备将加强一个联盟的研究，该联盟包括其他五家机构：德克萨斯大学圣安东尼奥分校、三一大学（位于圣安东尼奥）、西南大学（位于乔治城）、德克萨斯州立大学（位于圣马科斯）和贝勒大学（位于韦科）。 该仪器将用于广泛的研究，重点关注催化、电子和光子材料、环境研究、燃料电池研究和生物材料。 X射线光电子能谱仪使研究人员能够探测软（有机）和硬（无机）材料的表面成分和化学元素的氧化态。 该仪器配置为提供深度剖析和成像功能。 成像分辨率大约为微米级。 这使得研究人员能够将化学和物理特性与化学成分相关联。 该仪器将实现自动化，以便场外用户能够在样品运行完成后从其所在机构收集和分析数据。 大部分研究将集中在与能源相关的研究，特别是催化和环境研究。 来自奥斯汀周边地理区域的本科生和研究生将受益于这种远程访问仪器提供的培训。 UT（奥斯汀）将把这项技术引入一个新的试点项目，即一年级本科生实验室，让学生参与研究问题。
