Chemistry and Dynamics of Solids under High Pressures and other Extreme Conditions

这项研究计划由几个具有共同主题的项目组成，了解凝聚材料在高压和极端温度下的化学、动力学、结构和电子性质。研究集中在五个方面：1.简单固体和固体混合物在高压下的熔融和其他相平衡2.在室温下寻找金属氮3.极高静压下的不饱和碳化合物4.苯的冲击分解化学和激波前后的电子能谱5.极端条件下的X射线衍射。然而，他们研究的许多系统都相对简单，因为它们的性质可以由理论家建模。他们试图以足够的精度确定这些材料在高压下的行为，以测试这些模型的准确性，从而有助于提高他们对材料如何在分子水平上响应高应力的理解。//

This research program consists of several projects with a common theme, understanding the chemistry, dynamics, structures, and electronic properties of condensed materials under high pressures and, often, extremes of temperature. The research centers on five problem areas: 1. Melting and Other Phase Equilibria of Simple Solids and Solid Mixtures at High Pressures 2. A Search for Nitrogen Metal at Room Temperature 3. Unsaturated Carbon Compounds at Very High Static Pressures 4. Shock-Decomposition Chemistry of Benzene and Electronic Spectra from and behind Shock Fronts 5. X-Ray Diffraction under Extreme Conditions The emphasis is experimental. However, many of the systems they study are relatively simple in the sense that their properties can be modeled by theorists. They attempt to determine how these materials behave at high pressures with sufficient precision to test the accuracy of these models and, thereby, to contribute to improving their understanding of how materials respond to high stresses on the molecular level. //
