MRI: Acquisition of an X-ray Photoelectron Spectrometer for Research and Education

技术摘要附属于印第安纳大学纳米尺度表征设备的研究人员请求支持购买也配备有紫外线光电子能谱(UPS)的X射线光电子能谱仪。X射线光电子能谱(XPS)是表面和材料研究的基本分析技术。它相当于有机化学家的核磁共振，为那些研究固体的人提供了表面的元素组成和化学/电子状态信息。这一两用仪器将直接影响从用于太阳能的有机或无机材料的开发、化学传感和催化应用，到涉及新材料结构确定和水或有机分子与表面相互作用的基础研究。这些项目的关键是准备材料的化学和电子状态信息，其中XPS和UPS是用于获取此类信息的最先进方法。这一仪器将使我们能够阐明我们正在研究的纳米材料的复杂结构-功能关系，解决基本问题，同时推动我们的项目朝着满足社会需求的更多功能材料方向发展。从这些项目中获得的信息将产生广泛的影响，在有机/无机/固态化学、凝聚态物理、表面科学、材料科学和地质科学等科学学科之间建立联系。一般摘要纳米科学关注的是尺寸小于百万分之一米的材料的独特性质。测量和理解与这类材料相关的基本现象的能力对于推进现代科学的许多领域至关重要，包括能源生产、环境补救以及生物医学和信息技术。这些领域的研究是高度跨学科的，需要使用共享仪器来创建和表征纳米材料。因此，印第安纳大学布鲁明顿分校建立了一个共享设施--纳米表征设施，并请求为购买一台用于研究和教育的X射线光电子能谱仪提供支助。该仪器还将配备紫外光电子能谱。现场X射线和紫外光电子能谱将使印第安纳大学的研究人员和学生能够更好地了解给定材料的结构和组成如何产生其独特的性质。这些信息将允许更好地设计在一系列应用中使用的纳米材料。收购这台仪器也将产生广泛的影响，在科学学科之间建立联系，帮助将NCF提升为世界级的研究设施，加强跨学科科学方面的本科生和研究生培训，并促进广泛的外联活动，在这些活动中，印第安纳大学的纳米科学中心与地区学术和研究机构(包括HBCU)、工业团体、K-12教育工作者和校园组织建立了合作伙伴关系。

Technical AbstractResearchers affiliated with Indiana University's Nanoscale Characterization Facility request support for the acquisition of an X-ray Photoelectron Spectrometer, also equipped with Ultraviolet Photoelectron Spectroscopy (UPS). X-ray Photoelectron Spectroscopy (XPS) is a fundamental analytical technique for surface and materials-based research. It is the equivalent of nuclear magnetic resonance to organic chemists, providing those studying solids with elemental composition and chemical/electronic state information of surfaces. This dual-use instrument will have immediate impact on research ranging from the development of organic or inorganic materials for solar energy, chemical sensing, and catalytic applications to fundamental studies involving structure determination of new materials and the interactions of water or organic molecules with surfaces. Critical to these projects is chemical and electronic state information for prepared materials, of which XPS and UPS are the state-of-the-art methods used to obtain such information. This instrumentation will allow us to elucidate the complex structure-function relationships of the nanomaterials we are studying, addressing fundamental questions while also propelling our projects forward towards more functional materials that address societal needs. The information garnered from these projects will have broad impacts, forging links between scientific disciplines that include organic/inorganic/solid-state chemistry, condensed matter physics, surface science, material science, and the geological sciences.General AbstractNanoscience is concerned with the unique properties of materials with sizes less than about a millionth of a meter. The ability to measure and understand the fundamental phenomena associated with such materials is essential to advancing many areas of modern science, including energy production, environmental remediation, and biomedical and information technology. Research in these fields is highly interdisciplinary and requires access to shared instrumentation for creating and characterizing nanoscale materials. Thus, Indiana University - Bloomington has established a shared facility, the Nanoscale Characterization Facility, and is requesting support for the acquisition of an X-ray Photoelectron Spectrometer for research and education. This instrument also will be equipped with Ultraviolet Photoelectron Spectroscopy. On-site X-ray and Ultraviolet Photoelectron Spectroscopy will allow researchers and students affiliated with Indiana University to better understand how the structure and composition of a given material give rise to its unique properties. This information will allow for the better design of nanoscale materials used in a range of applications. The acquisition of this instrument will also have broad impacts, forging links between scientific disciplines, helping to elevate the NCF to a world-class research facility, enhancing undergraduate and graduate training in interdisciplinary science, and contributing to broad outreach activities in which the IU's Nanoscience Center partners with regional academic and research institutions (including HBCUs), industrial groups, K-12 educators, and campus organizations.
