MRI: Acquisition of a Confocal Micro-Raman Spectrometer

该主要研究仪器奖将获得一台拉曼光谱仪，用于达拉斯-沃斯堡大都会中心的研究、教育和更广泛的影响。拉曼光谱利用光的非弹性散射来探测气体、液体和固体中分子振动的能量。这些振动的能量可以揭示物质的化学、结构和热性质的丰富知识，具有纳米级的分辨率。这些细节对于克服从行星科学到纳米技术等许多科学和工程领域的一些最大挑战至关重要。该仪器将位于大都会中心的南卫理公会大学，为附近的学术、工业和文化机构提供研究和教育机会。在南卫理公会大学，从仪器中提取的知识将通过卡鲁斯工程教育研究所支持K-12科学、技术、工程和数学课程。除此之外，它还将加强该地区许多博物馆的艺术品保护工作。拉曼光谱学将有助于计算化学、行星科学、古生物学和纳米电子学领域的基础和应用研究。在计算化学领域，它将为振动光谱的理论研究提供实验对应物，包括高精度计算光谱或解码复杂光谱中潜在化学键的新方法。在行星科学领域，它将提供纳米级地质特征的细节，揭示诸如大陆地壳演化和大型陨石撞击等戏剧性事件的见解。拉曼光谱还将有助于探索天体的矿物学，比如土星的卫星土卫六，它与地球的大气层有着惊人的相似之处。在古生物学领域，它将识别生物分子，从而可以推断关于化石的颜色、体温和史前环境的新知识。在纳米技术领域，它将支持电子和量子器件的新型二维晶体和异质结构的发展。拉曼测温也将使研究人员能够探测这些器件的自热和散热，这可能是现代纳米电子学发展的最大障碍。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This Major Research Instrumentation award is to acquire a Raman spectrometer for research, education, and broader impacts in the Dallas-Fort Worth Metroplex. Raman spectroscopy uses the inelastic scattering of light to probe the energy of molecular vibrations in gases, liquids, and solids. The energy of these vibrations can reveal a wealth of knowledge on the chemical, structural, and thermal properties of matter, with nanoscale resolution. Such details are essential to overcoming some of the greatest challenges in many fields of science and engineering, spanning from planetary sciences to nanotechnology. The instrument will be located at Southern Methodist University, in the heart of the Metroplex, providing research and educational opportunities to nearby academic, industrial, and cultural institutions. At Southern Methodist University, knowledge distilled from the instrument will support K-12 science, technology, engineering, and mathematics programs through the Caruth Institute for Engineering Education. In addition to this, it will bolster artwork conservation efforts at the many museums in the region.Raman spectroscopy will contribute to fundamental and applied research in areas of computational chemistry, planetary sciences, paleontology, and nanoelectronics. In the field of computational chemistry, it will provide an experimental counterpart to theoretical research on vibrational spectra, including new methods of computing spectra with extreme accuracy or decoding the underlying chemical bonds in complex spectra. In the field of planetary sciences, it will provide details on nanoscale geological features, unlocking insights into dramatic events like the evolution of continental crust and large meteorite impacts. Raman spectroscopy will also aide in exploring the mineralogy of celestial bodies, like Saturn’s moon, Titan, which possesses striking similarities to Earth’s atmosphere. In the field of paleontology, it will identify biomolecules, which can infer new knowledge on the color, body temperature, and prehistoric environment of fossils. In the field of nanotechnology, it will support the development of new two-dimensional crystals and heterostructures for electron and quantum devices. Raman thermometry will also enable researchers to probe self-heating and heat dissipation in these devices, which is perhaps the largest obstacle to progressing modern nanoelectronics.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.
