Raman spectroscopy is a critical tool used to study bonding between atoms, which allows direct interrogation of both ordered and disordered systems. Such studies often provide new understanding of the atomic-scale origins of the function and properties of materials for next-generation applications. The proposed research, largely within a materials science department, will focus on ceramics and glasses used in energy storage and renewable energy, transportation, energy conversion, health care and defense. Unique to the proposed research is the ability to perform studies at the highest temperatures currently attainable - and with positional resolution using 3-D mapping. By direct examination of materials in-situ or under operating conditions, the research teams aim to uncover new atomic scale processes that can in turn be used to make transformational progress in materials discovery and design. In addition to the research applications, the instrument will be used in graduate and undergraduate laboratory courses, providing a range of baccalaureate and graduate students with training and experience in state-of-the-art materials characterization. With integration into the High Temperature Materials Testing Laboratory (HTMT) and the new Advanced Manufacturing Laboratory (AML) at Alfred University, the Raman spectrometer will be professionally marketed for use by industry and is expected to draw additional corporate users. Alfred University's strong history of industrially-funded research includes collaborations with 50 companies, and these links are expected to draw a continuous stream of corporate Raman users, with new users attracted to campus for Raman studiesRaman spectroscopy is a critical tool for uncovering the structural origins of materials properties and processing dynamics, especially when performed under conditions of controlled temperature or gaseous environment (in-situ) or under operating conditions (operando). In the atmosphere of a materials science department, high temperature Raman spectroscopy can be enabling in building comprehensive models of cation or anion disorder, defects in 2-D oxide nanosheets and related nanomaterials, glass devitrification, materials degradation mechanisms, residual stress, and similar problems. The Raman microprobe will be equipped with 3-D mapping and temperature-controlled chambers to enable discovery of new mechanisms that may lead to transformational progress in the fields of energy, environment and health care.

拉曼光谱是研究原子间键合的重要工具，它可以直接研究有序和无序体系。这些研究通常为下一代应用提供对材料功能和性质的原子尺度起源的新理解。 拟议中的研究主要在材料科学系内进行，将重点关注用于储能和可再生能源、交通、能源转换、医疗保健和国防的陶瓷和玻璃。 这项研究的独特之处在于能够在目前可达到的最高温度下进行研究，并使用3-D映射进行位置分辨率。 通过在原位或操作条件下直接检查材料，研究团队的目标是发现新的原子尺度过程，这些过程可以反过来用于在材料发现和设计方面取得变革性进展。 除了研究应用外，该仪器还将用于研究生和本科生实验室课程，为一系列学士和研究生提供最先进材料表征方面的培训和经验。随着与阿尔弗雷德大学的高温材料测试实验室（HTMT）和新的先进制造实验室（AML）的集成，拉曼光谱仪将被专业地推向市场，供行业使用，预计将吸引更多的企业用户。阿尔弗雷德大学在工业资助研究方面的强大历史包括与50家公司的合作，这些联系预计将吸引持续的企业拉曼用户，新用户被吸引到校园进行拉曼研究拉曼光谱是揭示材料特性和加工动力学的结构起源的关键工具，特别是当在受控温度或气体环境条件下（原位）或在操作条件下（操作）进行时。在材料科学部门的气氛中，高温拉曼光谱可以在建立阳离子或阴离子无序、2-D氧化物纳米片和相关纳米材料中的缺陷、玻璃失透、材料降解机制、残余应力和类似问题的综合模型中实现。该拉曼微探针将配备3D绘图和温控室，以发现可能导致能源，环境和医疗保健领域变革性进展的新机制。
