这项重大研究仪器（MRI）奖支持收购一个拉曼光谱系统，该系统与原子力显微镜集成，能够进行三维结构和拉曼映射，能够进行低温到高温操作（77？1，800 K），配备有用于拉曼探测的五个不同波长，并与用于泵浦激光器的附加集成路径对准。 该拉曼光谱系统将显著影响并实现广泛的研究项目，包括纳米材料合成和组装、碳检测和识别以及化学和生物传感。 它还将在验证计算纳米科学倡议方面发挥重要作用。 该仪器还将推进对超高温和极端化学环境下的拉曼过程的理解，沿着进一步推进集成拉曼原子力显微镜过程和尖端增强拉曼散射领域。拉曼光谱是表征物质频率、能量和指纹的强大技术。 该仪器将被安置在Wilsdorf Hall，这是一个最近完成的设施，致力于尖端的多学科研究，并在弗吉尼亚大学纳米材料表征设施（NMCF）的现有基础设施下积极管理，运营和支持。 将利用该仪器的现有研究重点是跨学科的，连接工程学院和艺术与科学学院的各个部门，范围从基础科学和材料发现到供水中的污染物检测。 该工具将被整合到课堂和实验室的讨论和活动在多个类在本科和研究生水平的组合，跨越六个学科，从而影响不同的观众。 在现有的可再生能源大学和可再生能源技术方案中也将鼓励使用这一工具，这些方案以代表性不足的群体为目标，使他们接触最前沿的研究。

This Major Research Instrumentation (MRI) award supports acquisition of a Raman spectroscopy system that is integrated with an atomic force microscope, capable of three-dimensional structural and Raman mapping, capable of cryogenic to high temperature operation (77 ? 1,800 K), outfitted with five different wavelengths for Raman probing, and aligned with an additional integrated path for a pump laser. The Raman spectroscopy system will significantly impact and enable a wide range of research projects, including nanomaterial synthesis and assembly, carbon detection and identification, and chemical and biological sensing. It will also play an important role in the validation of computational nanoscience initiatives. The instrument will also advance the understanding of Raman processes at ultra-high temperatures and extreme chemical environments, along with furthering the field of integrated Raman-atomic force microscopy processes and tip-enhanced Raman scatteringRaman spectroscopy is a a powerful technique for characterizing frequencies, energies, and fingerprints of matter. This instrument will be housed in Wilsdorf Hall, a recently completed facility dedicated to cutting-edge, multidisciplinary research and actively managed, operated, and supported under the existing infrastructure of the Nanoscale Materials Characterization Facility (NMCF) at the University of Virginia. Existing research thrusts that will utilize the instrument are interdisciplinary, connecting various departments in the Engineering School and the College of Arts and Sciences, and range from basic science and materials discovery to contaminant detection in water supplies. The instrument will be integrated into a combination of classroom and laboratory discussions and activities in multiple classes at both the undergraduate and graduate levels, spanning six disciplines, thus impacting a diverse audience. The use of this instrument will also be encouraged in existing REU and RET programs, which target underrepresented groups and expose them to cutting edge research.
