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.

该奖项得到了主要的研究工具（MRI），化学研究工具（CRIF）计划和刺激竞争研究（EPSCOR）的既定计划的支持。特拉华大学及其同事劳尔·洛博（Raul F Lobo），约翰·F·拉伯特（John F Rabolt），托马斯·汉森（Thomas E Hanson）和乔斯琳·阿尔坎塔拉·加西亚（Jocelyn Alcantara-Garcia）的卡尔·布克斯（Karl Booksh）教授已经获得了原子力量拉曼显微镜。拉曼显微镜是表面和大量样品的主要特征技术。使用激光，显微镜扫描样品，该样品产生振动光谱数据，从而提供有关材料的化学信息。原子力显微镜（AFM）还使用小探头或尖端扫描样品，以提供有关地面，硬度，电气和热性能等表面的信息。在AFM-RAMAN显微镜中将两种技术组合在一起，提供了来自样品相同区域的两种类型的信息。它在纯净和应用科学和工程的研究努力中广泛应用。 一个重要的应用是在研究表面上使用催化剂将甲烷转化为甲醇等化学物质的研究。显微镜将使表面物种的反应与反应条件的关系进行研究，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所学院，13个系以及特拉华州立大学（DSU，A HBCU）和Winterthur博物馆的用户。拉曼显微镜将显着使UD和DSU的女性，少数和初级教师受益。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得到极大的增强。该提案旨在增强各级研究和教育。三层同轴电素聚合物纳米纤维的结构和形态正在投资中，并分析了高抗拉力强度聚合物。 正在研究表面的化学修饰，含铜沸石催化剂上的甲烷激活以及木质纤维素生物量向化学物质和燃料的催化转化。 分层半导体纳米复合材料的合成是从该仪器中受益的另一个研究领域。 探索了环境样品中的微生物铁和硫 - 氧化和生物矿物组成，并在叶绿体曲霉中的硫代谢机制和控制。 Winterthur博物馆保护部内的Winterthur科学研究和分析实验室正在使用显微镜提供的非破坏性器乐技术在对艺术和文化遗产的分析中提供的。该奖项反映了NSF的法定任务，并通过使用该基金会的知识优点和广泛影响来评估NSF的法定任务。
