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.

该奖项为阿贡国家实验室（芝加哥，IL）高级光子源（APS）的共享使用，最先进的组合拉曼和光谱系统的收购提供资金。 这一新系统将使研究具有独特物理和化学性质的材料以及新技术材料成为可能，并将先进的最先进技术结合在一台仪器中。这项工作对社会生活质量问题具有重要意义，如碳封存，环境修复，纳米材料的特性和地震发生。这项工作也将促进学生的发现和理解，作为拟议的研究的参与者。一个系统的可用性，能够伴随原位X射线衍射和光谱研究的材料在环境和极端的压力和温度条件（静态和动态），包括高空间分辨率的研究先进的和新合成的材料，将大大提高APS用户的研究能力。这一仪器将使我们能够在相关条件下研究合成样品以及研究天然矿物、岩石及其内含物，从而增进我们对行星内部的了解。同样，在高压和变温（低到很高）条件下的材料研究将揭示极端条件下凝聚态物质的物理和化学现象，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。对纳米材料等降维材料的研究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。
