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.

该重大研究仪器(MRI)奖支持购买拉曼光谱系统，该系统与原子力显微镜集成在一起，能够进行三维结构和拉曼映射，能够从低温到高温操作(77？1800K)，配备了五种不同的拉曼探测波长，并与泵浦激光的额外集成路径对准。拉曼光谱系统将对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在内的广泛研究项目产生重大影响并使之成为可能。它还将在验证计算纳米科学倡议方面发挥重要作用。该仪器还将促进对超高温和极端化学环境下的拉曼过程的理解，以及促进集成拉曼-原子力显微镜过程和尖端增强拉曼散射的领域，拉曼光谱是表征物质频率、能量和指纹的一种强大技术。该仪器将安置在威尔斯多夫大厅，这是一个最近建成的致力于尖端、多学科研究的设施，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。将利用该仪器的现有研究项目是跨学科的，连接了工程学院和艺术与科学学院的各个系，范围从基础科学和材料发现到供水中的污染物检测。该工具将融入本科生和研究生阶段多个班级的课堂和实验室讨论和活动，涉及六个学科，从而影响到不同的受众。还将鼓励在现有的REU和RET计划中使用这一工具，这些计划针对的是代表性不足的群体，并使他们接触到尖端研究。
