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.

隶属于印第安纳大学纳米级表征设施的技术Abstractresearchers要求支持X射线光电子光谱仪，该X射线光电光谱仪也配备了紫外光光谱光谱仪（UPS）。 X射线光电子光谱（XPS）是一种基于表面和材料研究的基本分析技术。它等效于有机化学家的核磁共振，提供了研究固体的元素组成和表面化学/电子状态信息的人。这种双重使用仪器将立即对研究产生直接影响，从有机或无机材料开发用于太阳能，化学感应和催化应用到涉及新材料的结构以及水或有机分子与表面的相互作用的基础研究。这些项目至关重要的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新方法。这种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，并解决了基本问题，同时也将我们的项目推向了满足社会需求的更多功能材料。从这些项目中获得的信息将产生广泛的影响，在包括有机/无机/固态化学，凝结物理学，表面科学，材料科学和地质科学在内的科学学科之间建立了联系。一般的AbstractNananoscience与材料的独特特性相关，其材料的独特特性少于尺寸的尺寸。衡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，包括能源生产，环境补救以及生物医学和信息技术至关重要。这些领域的研究是高度跨学科的，需要访问共享仪器来创建和表征纳米级材料。因此，印第安纳大学 - 布卢明顿（Bloomington）建立了共享设施，纳米级表征设施，并要求支持收购X射线光电子光谱仪进行研究和教育。该仪器还将配备紫外线光谱。现场X射线和紫外线光学光谱学将使与印第安纳大学的研究人员和学生更好地了解给定材料的结构和组成如何产生其独特的特性。此信息将允许在一系列应用中使用的纳米级材料更好地设计。该乐器的获取也将产生广泛的影响，在科学学科之间建立联系，有助于将NCF提升到世界一流的研究机构，增强了跨学科科学领域的本科和研究生培训，并为IU纳米科学中心中心的广泛宣传活动做出了贡献，在该活动中，与该地区和研究机构（包括HBCSUSES）（包括HBCCUS）（包括HEBCUS），KCRIANDIANS，KIDIANS，包括HEBCUS，kcus and Industrial k.12。
