18 Μαρ 2020 · Phase changes can be easily identified in simulation, by directly imaging the atoms and measuring correlation functions. We show that the room-temperature XRD patterns for hydrogen phases I, III, IV, and V are very similar.
8 Απρ 2024 · In this study, starting from the phase I of solid hydrogen—free-rotator hcp structure, we conduct extensive ab initio molecular dynamics calculations to simulate the cooling, heating, and equilibrium processes within a pressure range of 80–260 GPa.
We report a phase diagram mapping for solid hydrogen based on several thousands of Raman spectroscopic data points obtained at simultaneous high-pressure and -temperature (PT) experiments.
1 Φεβ 2020 · Hydrogen is expected to display remarkable properties under extreme pressures and temperatures stemming from its low mass and thus propensity to quantum phenomena.
26 Ιαν 2017 · Metallic hydrogen may be a room-temperature superconductor and metastable when the pressure is released and could have an important impact on energy and rocketry. We have studied solid molecular hydrogen under pressure at low temperatures.
27 Μαΐ 2007 · We have systematically investigated the zero-temperature phase diagram of solid hydrogen using first-principles density functional theory (DFT) electronic-structure methods 4, including...
6 Οκτ 2020 · Quantum phase diagram of high-pressure hydrogen. Evidence for supercritical behaviour of high-pressure liquid hydrogen. Introduction. Since the discovery of solid molecular hydrogen in...
