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 · The low-pressure phase I of solid hydrogen, which consists of freely rotating molecules on a hexagonal close-packed lattice 2, transforms at pressures of about 110 GPa to the broken-symmetry...
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.
21 Ιουλ 2016 · At energies below the electronic excitation energy, the thermal and spectroscopic pro perties of these solids are determined by the translational, rotational, and intramolecular vibrational motions of the interacting molecules.
28 Ιουλ 2015 · Pc -48 can account for the occurrence of stiff and soft vibronic modes in phase IV, and its stabilization by temperature. Finally, we consider the Cmca -4 structure 33, which has weaker molecular...
11 Απρ 2002 · Here we report optical measurements of solid hydrogen up to a pressure of 320 GPa at 100 K.
18 Μαρ 2020 · We present simulated x-ray diffraction patterns (XRD) from molecular dynamics studies of phase transformations in hydrogen at room temperature. Phase changes can be easily identified in simulation, by directly imaging the atoms and measuring correlation functions.
