Multimegabar Research: X-ray and Optical Studies

9530634鲁夫这个研究项目将把分子固体的静态压力范围从230Gpa扩大到460Gpa以上，并将提供对氢、氧、氮以及碱氢化物的新形式的研究。目标是制造和研究固体原子金属氢、氧和氮。研究氢化物的目的是为了更多地了解氢化物离子的性质。将使用X射线衍射和光学研究、拉曼光谱、吸收光谱和反射光谱。将强调微小型化，将金刚石顶尖减少到20微米，耐火垫片材料的初始样品孔直径为6微米。这个研究项目计划制造固体原子金属氢，它被预测为高温超导体。该项目还计划形成氧和氮的固体原子金属。其目的是为理解这些独特的新金属提供坚实的基础。为了实现这些目标，该项目计划将研究分子固体的压力范围扩大一倍，达到460 Gpa(或4.6 Mbar或460万大气压)，高于地核的压力。这项研究的目的之一是确定金属氢能否在大气压下持续存在。如果达到这一目标，可能会有一些独特的应用。***

9530634 Ruoff This research project will extend the static pressure range on molecular solids to above 460 GPa - from 230 GPa - and will provide a study of new forms of hydrogen, oxygen, and nitrogen as well as alkali hydrides. The objective is to make and study solid atomic metallic hydrogen, oxygen and nitrogen. The study of hydrides has the intent of learning more about the nature of the hydride ion. X-ray diffraction and optical studies, Raman, absorption, and reflection spectroscopy will be used. Microminiaturization will be emphasized with diamond anvil tips reduced to 20 micrometers and initial sample hole diameters in the refractory gasket material of 6 micrometers. %%% This research project plans to make solid atomic metallic hydrogen that has been predicted to be a high temperature superconductor. Solid atomic metals of oxygen and nitrogen are also planned to be formed during this project. The intent is to provide a strong fundamental basis for the understanding of these unique new metals. To achieve these goals this project plans to double the pressure range to which molecular solids have been studied to reach 460 GPa (or 4.6 Mbar or 4.6 million atmospheres) which is greater than the pressure at the earth's core. An objective of this research is to determine whether metallic hydrogen can persist at atmospheric pressure. If this objective is met there may follow some unique applications. ***
