Solid hydrogen is the solid state of the element hydrogen, achieved by decreasing the temperature below hydrogen's melting point of 14.01 K (−259.14 °C; −434.45 °F).
27 Μαΐ 2007 · We have systematically investigated the zero-temperature phase diagram of solid hydrogen using first-principles density functional theory (DFT) electronic-structure methods4, including the...
21 Ιουλ 2016 · The solid hydrogens are dominated by quantum effects, the most out standing property being that the rotation of the molecules is free down to the lowest temperatures, in the sense that the rotational quantum number J characterizing the rotational motion of the free molecules remains a good quantum number in all of the solid-state phases ...
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.
25 Σεπ 2019 · Our knowledge of celestial bodies such as the Sun, which is about 75% hydrogen 1, relies on understanding the properties of this element at extreme temperature and pressure.
29 Ιαν 2020 · Solid hydrogen should exhibit a high level of electrical conduction that should then decrease as the sample temperature is raised. However, even with experimental techniques developed in the...
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.
