MRI: Acquisition of a Three-Dimensional Multi-Wavelength Raman Spectrometer for the Nanotechnology Characterization

该主要研究仪器（MRI）奖支持采购拉曼光谱系统，该系统集成了原子力显微镜，能够三维结构和拉曼映射，能够低温到高温操作(77 ？1800 K)，配备了五个不同波长的拉曼探测，并与一个泵浦激光器的附加集成路径对齐。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，碳检测和鉴定，以及化学和生物传感。它还将在计算纳米科学计划的验证中发挥重要作用。该仪器还将推进对超高温和极端化学环境下拉曼过程的理解，同时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的研究。该仪器将被安置在Wilsdorf大厅，这是一个最近完成的设施，致力于前沿，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，操作和支持。利用该仪器的现有研究重点是跨学科的，连接了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。该仪器将被整合到本科和研究生阶段的课堂和实验室讨论以及多个班级的活动中，涵盖六个学科，从而影响不同的受众。现有的REU和RET计划也将鼓励使用这一工具，这些计划针对代表性不足的群体，并使他们接触到前沿研究。

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.
