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.
14 Αυγ 2023 · 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. Information about phase behavior in the range of 300 K up to the melting line and 0--300 GPa for hydrogen has remained almost unknown to date; therefore ...
20 Νοε 2019 · Extensive experimental and theoretical studies have been devoted to determining the high-pressure phase diagram of hydrogen. We present evidence of a phase at a higher pressure than phase III and below the pressure of the recently observed phase of metallic hydrogen (495 GPa).
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.
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.
28 Ιουλ 2015 · Several crystalline phases of solid molecular H have been observed in diamond anvil cell experiments carried out at pressures up to over 300 GPa (refs 11, 12, 13, 14, 15, 16, 17, 18, 19).
