This award is jointly supported by the Major Research Instrumentation and the Chemistry Research Instrumentation Programs. The University of Texas at El Paso is acquiring an X-ray photoelectron spectrometer (XPS) to support the research of Professor XiuJun Li and colleagues Carlos Cabrera Martinez, Jorge Gardea-Torresdey, Hongmei Luo, and Sreeprasad Sreenivasan. This instrument facilitates research in the areas of chemistry, materials science, and physics. XPS spectra are produced by irradiating a sample with X-rays that have sufficient energy to eject electrons. Next, the kinetic energy of the electrons is measured and subsequently related to their binding energy. These data can be related to the chemical elements in the sample and effects from their bonding environment. This instrument enhances the educational, research, and teaching efforts of students at all levels in many departments and broadly impacts research in the fields of catalysis, sensing, energy materials, magnetic materials, and additive manufacturing. The instrument is leveraged in many courses including a new course focused on surface analysis. The award for the XPS is aimed at enhancing research and education at all levels to explore advanced surface chemistry, new properties of advanced materials and sensors through systematic characterization of elemental, chemical, and structural information by this instrument, thus meeting the research and educational needs of the southwest region. Research focuses on investigations relevant to catalysis, electrocatalysts for water electrolysis, photovoltaic applications. It also assists in studies involving nanostructure catalysts relevant to fuel cells and investigations of novel energy storage materials. Other studies focus on understanding structural and compositional impacts on doped graphene quantum dots for electrocatalysis, sensing and quantum science; nanoparticle transport in plant structures; 3D printed non-oxide ceramics; and magnetic nanoparticles for nanoelectronics, data storage devices and quantum computing.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.

该奖项由主要的研究工具和化学研究工具计划共同支持。德克萨斯大学埃尔帕索分校正在收购X射线光电子光谱仪（XPS），以支持Xiujun Li和同事Carlos Cabrera Martinez，Jorge Gardea-Torresdey，Hongmei Luo和Sreeprasad Sreenivasan的研究。该仪器促进了化学，材料科学和物理领域的研究。 XPS光谱是通过用具有足够能量排出电子的X射线照射样品来产生的。接下来，测量电子的动能并随后与它们的结合能有关。这些数据可能与样品中的化学元素及其键合环境的影响有关。该工具可以在许多部门的各个层面上增强学生的教育，研究和教学工作，并广泛影响催化，感应，能源材料，磁性材料和添加剂制造领域的研究。该仪器在许多课程中都利用了，包括专注于表面分析的新课程。 XP的奖项旨在通过该乐器通过系统地表征元素，化学和结构信息来探索各个层次的研究和教育，以探索先进的表面化学，高级材料和传感器的新特性，从而满足西南地区的研究和教育需求。研究重点是与催化，电解电解的电催化剂有关的研究，光伏应用。它还有助于研究涉及与燃料电池相关的纳米结构催化剂的研究以及对新型储能材料的研究。其他研究着重于理解对电催化，传感和量子科学的掺杂石墨烯量子点的结构和组成影响。植物结构中的纳米颗粒运输； 3D打印的非氧化陶瓷；和用于纳米电子学，数据存储设备和量子计算的磁性纳米颗粒。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响评估标准通过评估来支持的。
