CAREER: Structure, Defects, and Chemistry of Transition Metal Oxide Surfaces

该学院早期职业发展（CAREER）项目的目标，在分析和表面化学计划的支持下，是具有广泛的科学和技术应用的过渡金属氧化物表面的表面化学，结构和缺陷的表征。 Diebold教授和她在杜兰大学的本科生和研究生将在这项工作中使用一系列表面表征技术，包括扫描隧道显微镜，X射线光电子能谱，离子散射光谱和热解吸光谱。 这个CAREER研究项目的目的是在原子水平上探测这些氧化物表面的缺陷形成和反应性，为理解这些表面发生的化学反应奠定基础。 除了学生参与这项研究的教育推力涉及一个新的表面科学课程的发展，以补充实验室的经验和推广和指导计划围绕建立一个移动的扫描隧道显微镜实验室为中心。 过渡金属氧化物表面用于制造气体传感器、催化剂、防腐涂层和环境降解系统。 迪博尔德教授和她的学生在杜兰大学将应用几种表面光谱方法，提供原子尺度的空间分辨率的化学，结构和过渡金属氧化物表面的缺陷的研究与支持这个职业研究项目。 在这些氧化物表面发生的化学反应高度依赖于那里存在的结构。 这些结构如何控制这些化学反应的知识将通过这项工作产生。 这个动手实验计划将对从事该项目的本科生和研究生产生积极的教育影响。 将开发便携式扫描隧道显微镜实验和其他表面科学实验，为新奥尔良和密西西比三角洲地区的高中生带来这项工作的兴奋。 这项活动将提高这些学生对科学职业生涯中可能经历的兴奋的认识。

The objective of this Faculty Early Career Development (CAREER) project, supported in the Analytical and Surface Chemistry Program, is the characterization of the surface chemistry, structure, and defects of transition metal oxide surfaces that have broad scientific and technological application. Professor Diebold and her undergraduate and graduate students at Tulane University will use a range of surface characterization techniques in this work including scanning tunneling microscopy, X-ray photoelectron spectroscopy, ion scattering spectroscopy, and thermal desorption spectroscopy. The aim of this CAREER research project is to probe the formation of defects and the reactivity of these oxide surfaces at the atomic level to establish a foundation for understanding the chemistry that occurs at these surfaces. Educational thrusts beyond involvement of students in this research involve the development of a new surface science course to complement the laboratory experience and an outreach and mentoring program centered around the establishment of a mobile scanning tunneling microscopy laboratory. Transition metal oxide surfaces are used in the fabrication of gas sensors, catalysts, coatings for corrosion protection, and environmental degradation systems. Professor Diebold and her students at Tulane University will apply several surface spectroscopic methods that provide atomic scale spatial resolution to the study of the chemistry, structure, and defects of transition metal oxide surfaces with support of this CAREER research project. The chemistry that occurs at the surfaces of these oxides is highly dependent on the structures that exist there. Knowledge of how these structures control these chemical reactions will be produced by this work. This hands-on experimental program will have a positive educational impact on the undergraduate and graduate students working on this project. Portable scanning tunneling microscopy experiments and other surface science experiments will be developed to bring the excitement of this work to high school students in the New Orleans and Mississippi Delta areas. This activity will raise these students' awareness of the excitement that can be experienced in a scientific career.
