该合同为阿贡国家实验室（芝加哥，伊利诺伊州）先进光子源（APS）的共享使用、最先进的联合拉曼和光学光谱系统的采购提供资金。这个新系统将能够研究具有独特物理和化学性质的材料，以及新的技术材料，将先进的技术结合在一个仪器中。这项工作对碳固存、环境修复、纳米材料特性和地震产生等社会生活质量问题具有重要意义。这项工作也将促进学生作为拟议研究的参与者的发现和理解。能够同时在环境和极端压力和温度条件下（静态和动态）对材料进行原位x射线衍射和光谱研究的系统的可用性，包括对先进和新合成材料的高空间分辨率研究，将大大提高APS用户的研究能力。通过研究相关条件下的合成样品和天然矿物、岩石及其内含物，该仪器将增强我们对行星内部的理解。同样，在高压和变温度（低到很高）条件下研究材料，将有助于理解凝聚态物质在极端条件下的物理和化学现象，包括相变和化学反应，为在极端条件下合成新材料提供基础。研究降维材料，如纳米材料，将促进我们对其电子和振动特性的理解，这是设计新的先进技术设备的关键信息。

This award provides funding for the acquisition of a shared-use, state-of-the-art combined Raman and optical spectroscopy system at the Advanced Photon Source (APS), Argonne National Laboratory (Chicago, IL). This new system will enable study of materials with unique physical and chemical properties, as well as novel technological materials, with advanced state-of-the-art techniques combined in a single instrument. This work has important implications to societal quality-of-life issues such as carbon sequestration, environmental remediation, properties of nanomaterials and earthquake generation. This work will also advance discovery and understanding by students as participants in the proposed research.The availability of a system capable of concomitant in-situ X-ray diffraction and spectroscopy studies of materials at ambient and extreme pressure and temperature conditions (static and dynamic), including high spatial resolution studies of advanced and newly synthesized materials, will greatly enhance research capabilities of APS users. This instrumentation will enhance our understanding of planetary interiors by enabling studies of synthetic samples at the relevant conditions and of naturally-occurring minerals, rocks and their inclusions. Similarly, study of materials under conditions of high pressures and variable temperatures (low to very high) will be revealing for understanding of physical and chemical phenomena in condensed matter under extreme conditions including phase transitions and chemical reactions which provide a basis for synthesis of new materials under extreme conditions. Study of materials with reduced dimensionality, such as nanomaterials, will advance our understanding of their electronic and vibrational properties, crucial information for designing new advanced technology devices.
