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

该研究项目由几个项目组成，这些项目都有一个共同的主题，即了解高压和极端温度下凝聚态材料的化学、动力学、结构和电子特性。研究主要集中在五个问题领域：1。简单固体和固体混合物在高压下的熔化和其他相平衡2。在室温下对金属氮的研究超高压下的不饱和碳化合物苯的激波分解化学及激波前后的电子谱在极端条件下的x射线衍射重点是实验。然而，他们研究的许多系统相对简单，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在分子水平上对高应力的反应的理解。//

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. //
