项目摘要

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.

技术摘要印第安纳大学纳米表征设施的研究人员请求支持购买一台 X 射线光电子能谱仪，该仪还配备了紫外光电子能谱 (UPS)。 X 射线光电子能谱 (XPS) 是表面和材料研究的基本分析技术。对于有机化学家来说，它相当于核磁共振，为研究固体的人们提供元素组成和表面化学/电子状态信息。这种两用仪器将对各种研究产生直接影响，从用于太阳能、化学传感和催化应用的有机或无机材料的开发，到涉及新材料结构测定以及水或有机分子与表面相互作用的基础研究。这些项目的关键是制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。该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，同时也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、凝聚态物理学、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独特的性质尺寸小于百万分之一米的材料。测量和理解与此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、环境修复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级材料。因此，印第安纳大学伯明顿分校建立了一个共享设施，即纳米级表征设施，并请求支持购买用于研究和教育的 X 射线光电子能谱仪。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附属的研究人员和学生更好地了解给定材料的结构和成分如何产生其独特的性能。这些信息将有助于更好地设计用于一系列应用的纳米级材料。该仪器的获得也将产生广泛的影响，在科学学科之间建立联系，帮助将 NCF 提升为世界一流的研究机构，加强跨学科科学的本科生和研究生培训，并为印第安纳大学纳米科学领域的广泛外展活动做出贡献。该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合作。
