CRIF:MU: Acquisition of a Cyber Enabled 500 MHz Solid State NMR Spectrometer

在化学研究仪器和设施：多用户计划（CRIF:MU）的支持下，爱荷华大学化学系将获得一台网络支持的500 MHz固态核磁共振（NMR）光谱仪。该光谱仪将用于化学科学的研究项目，包括：1)无机纳米结构和聚合物网络的合成和表征；2)环境界面的表面吸附和表面反应；3)利用溶致液晶系统研究纳米结构聚合物；4)沸石和介孔二氧化硅材料的研究；5)氟表面活性剂和多氯环境污染物的表征；6)利用核磁共振活性核（Si， F）作为标签监测固态反应性和自组装。核磁共振（NMR）光谱学是化学家分析材料最广泛使用的工具。它用于识别未知物质，并提供有关分子和材料中原子的排列和连通性的信息，即它们的结构。与广泛使用的溶液核磁共振相比，固态核磁共振需要特殊的仪器和技术。它提供了晶体和非晶体材料、聚合物和表面的化学键、结构和原子环境的关键信息。这个分光仪将加强爱荷华州许多促进本科生和研究生教学的项目。它将协助来自其他地区的本科生校园的用户的研究和教学活动，这些用户将在周末使用该仪器，通过一个外展计划，提供先进的仪器，以促进跨机构的合作，并鼓励这些机构的学生对研究生事业的兴趣，包括一些有大量未被充分代表的少数民族。

With support from the Chemistry Research Instrumentation and Facilities: Multiuser program (CRIF:MU), the Department of Chemistry at the University of Iowa will acquire a cyber enabled 500 MHz solid state nuclear magnetic resonance (NMR) spectrometer. The spectrometer will be used for research projects in the chemical sciences including: 1) synthesis and characterization of inorganic nanostructures and polymeric networks, 2) surface adsorption and surface reactions of environmental interfaces, 3) studies of nanostructured polymers using lyotropic liquid crystalline systems, 4) studies of zeolites and mesoporous silica materials, 5) characterization of fluorinated surfactants and polychlorinated environmental contaminants, and 6) monitoring solid state reactivity and self assembly using NMR-active nuclei (Si, F) as tags. Nuclear magnetic resonance (NMR) spectroscopy is the most broadly used tool available to chemists for the analysis of materials. It is used to identify unknown substances and to provide information on the arrangement and connectivity of atoms in molecules and materials i.e. their structures. Solid state NMR requires special instrumentation and techniques compared to the more widely used NMR of solutions. It provides critical information on the chemical bonding, structure and atomic environment in both crystalline and non-crystalline materials, polymers and on surfaces. This spectrometer will enhance many Iowa programs that promote teaching and learning of undergraduates and graduate students. It will assist the research and teaching activities of users from other regional undergraduate campuses who will use this instrument on weekends through an outreach program that provides access to advanced instrumentation to promote cross institutional collaborations and encourage interest in graduate careers of students at these institutions including several with large numbers of underrepresented minorities.
