This award is supported by the Major Research Instrumentation (MRI), the Chemistry Research Instrumentation (CRIF) programs and the Established Program to Stimulate Competitive Research (EPSCoR). Professor Karl Booksh from the University of Delaware and colleagues Raul F Lobo, John F Rabolt, Thomas E Hanson and Jocelyn Alcantara-Garcia have acquired an atomic force Raman microscope. Raman microscopy is a principal characterization technique for both surfaces and bulk samples. Using a laser, the microscope scans a sample which produces vibrational spectroscopic data providing chemical information about the material. An atomic force microscope (AFM) also scans a sample using a small probe or tip to provide information about the surface such as topography, hardness, electrical and thermal properties. Combining the two techniques in an AFM-Raman microscope provides both types of information from the same regions of the sample. It has wide application in research endeavors across the pure and applied sciences and engineering. An important application is use in the investigation of converting methane to chemicals such as methanol using a catalyst on a surface. The microscope will enable study of the reaction of surface species as a function of reaction conditions to optimize the yield of valuable products. The acquisition will impact 5 colleges, 13 departments at the University of Delaware (UD) and users at Delaware State University (DSU, an HBCU) and the Winterthur Museum. The Raman microscope will significantly benefit female, minority, and junior faculty at both UD and DSU. The research and training of a significant number of female and underrepresented minority students will also be greatly enhanced.The proposal is aimed at enhancing research and education at all levels. The structure and morphology of trilayer coaxial electrospun polymer nanofibers is under investiation, and analysis of high tensile strength polymers. Chemical modification of surfaces, methane activation over copper-containing zeolite catalysts and catalytic conversion of lignocellulosic biomass to chemicals and fuels is being studied. Synthesis of hierarchical semiconducting nano-composites is another research area to benefit from the instrument. The microbial iron- and sulfur-oxidation and biomineral composition in environmental samples is explored, and mechanisms and control of sulfur metabolism in chlorobaculum tepidum. The Winterthur Scientific Research and Analysis laboratory within the Department of Conservation at Winterthur Museum is using the non-destructive instrumental technique afforded by the microscope in the analysis of works of art and cultural heritage.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项得到了主要研究仪器 (MRI)、化学研究仪器 (CRIF) 计划和刺激竞争性研究既定计划 (EPSCoR) 的支持。特拉华大学的 Karl Booksh 教授及其同事 Raul F Lobo、John F Rabolt、Thomas E Hanson 和 Jocelyn Alcantara-Garcia 获得了一台原子力拉曼显微镜。拉曼显微镜是表面和块状样品的主要表征技术。显微镜使用激光扫描样品，产生振动光谱数据，提供有关材料的化学信息。原子力显微镜 (AFM) 还使用小探针或尖端扫描样品，以提供有关表面的信息，例如形貌、硬度、电性能和热性能。在 AFM-拉曼显微镜中结合这两种技术可以提供来自样品相同区域的两种类型的信息。它在纯科学和应用科学与工程的研究工作中有着广泛的应用。 一个重要的应用是研究使用表面催化剂将甲烷转化为甲醇等化学品。该显微镜将能够研究表面物质的反应作为反应条件的函数，以优化有价值产品的产量。此次收购将影响特拉华大学 (UD) 的 5 个学院、13 个系以及特拉华州立大学 (DSU，HBCU) 和温特图尔博物馆的用户。拉曼显微镜将使 UD 和 DSU 的女性、少数族裔和初级教师受益匪浅。对大量女性和代表性不足的少数族裔学生的研究和培训也将大大加强。该提案旨在加强各级的研究和教育。三层同轴电纺聚合物纳米纤维的结构和形貌正在研究中，并对高拉伸强度聚合物进行了分析。 正在研究表面化学改性、含铜沸石催化剂上的甲烷活化以及木质纤维素生物质催化转化为化学品和燃料。 分级半导体纳米复合材料的合成是受益于该仪器的另一个研究领域。 探索环境样品中的微生物铁氧化和硫氧化以及生物矿物质组成，以及绿藻硫代谢的机制和控制。 温特图尔博物馆保护部内的温特图尔科学研究和分析实验室正在使用显微镜提供的非破坏性仪器技术来分析艺术品和文化遗产。该奖项反映了 NSF 的法定使命，并被认为是值得的通过使用基金会的智力优势和更广泛的影响审查标准进行评估来提供支持。
