Title: New Phases and Dissociation-Recombination of Hydrogen Deuteride to 3.4 Mbar

Abstract

We present infrared absorption studies of solid hydrogen deuteride to pressures as high as 340 GPa (100 GPa =1 Mbar) in a diamond anvil cell and temperatures in the range 5–295 K. Above 198 GPa the HD sample transforms to a mixture of HD, H2, and D2, interpreted as a process of dissociation and recombination. Three new phase lines are observed, two of which differ remarkably from those of the high-pressure homonuclear species, but none are metallic. The time-dependent spectral changes are analyzed to determine the molecular concentrations as a function of time; the nucleon exchange achieves steady state concentrations in ~20 h at ~200 GPa.

High-Pressure Hydrogen Interactions with Polyaminoborane and Polyiminoborane

Journal Article Chellappa, Raja S ; Autrey, Thomas ; Somayazulu, Maddury ; ... - Chemphyschem, 11(1):93-96

Ammonia borane [NH3BH3, AB] is a prototypical Lewis acid (BH3)"Lewis base (NH3) adduct that is a stable molecular crystal at ambient temperature and pressure.[1] Upon heating, AB releases H2 in an exothermic reaction to form polyaminoborane [(NH2BH2)x, PAB] at temperatures below 1208C and decomposes further to polyiminoborane [(NHBH)x, PIB] above 1208C (Scheme S1, Supporting Information).[2-4] The structure and dynamics of AB, PAB and PIB is influenced by dihydrogen bonding (DHB)[5, 6] arising from the electrostatic interactions between protonic (Hd+) and hydridic (Hd*) H atoms and dative bonding due to donation of non-bonding lone pair on nitrogen to the empty p-orbitalmore »« less

Pressure dissociation of solid nitrogen under 1 Mbar

Journal Article McMahan, A K ; LeSar, R - Phys. Rev. Lett.; (United States)

The zero-temperature transition pressure from molecular to monatomic nitrogen is predicted to be less than about 1 Mbar, and should be observable in diamond-anvil cells. This estimate is obtained from total-energy calculations in which compressed molecular nitrogen is found to dissociate into a simple cubic monatomic structure, slight distortions of which are common to other group-V elements. The calculated 35% volume change raises the possibility of a large barrier to dissociation and extensive regions of metastability.

Opposed type double stage cell for Mbar pressure experiment with large sample volume

Journal Article Kono, Yoshio ; Kenney-Benson, Curtis ; Shen, Guoyin - High Pressure Research

We report a new opposed type double-stage large volume cell has been developed to compress large volume samples to more than 100 GPa (Mbar) pressure. A pair of second-stage diamond anvils is introduced into the first-stage Paris-Edinburgh press. The double-stage large volume cell allows the generation of ultrahigh pressures using a large culet diameter of the second-stage diamond anvils (diameters of 0.5-1.2 mm). Pressure generation up to 131 GPa has been achieved by using the culet diameter of 0.5 mm. Sample volume of the double-stage large volume cell can be more than similar to 100 times larger than that ofmore »« less

Using Laser-driven Shocks to Study the Phase Diagrams Of Low-Z Materials at Mbar Pressures and eV Temperatures

Journal Article Celliers, P M ; Eggert, J H ; Hicks, D G ; ... - AIP Conference Proceedings

Accurate phase diagrams for simple molecular fluids and solids (H2, He, H2O, SiO2, and C) and their constituent elements at eV temperatures and pressures up to tens of Mbar are integral to planetary models of the gas giant planets (Jupiter, Saturn, Uranus and Neptune), and the rocky planets. Laboratory experiments at high pressure have, until recently, been limited to around 1 Mbar. These pressures are usually achieved dynamically with explosives and two-stage light-gas guns, or statically with diamond anvil cells. Current and future high energy laser and pulsed power facilities will be able to produce tens of Mbar pressures inmore »« less

Conductivity and dissociation in liquid metallic hydrogen and implications for planetary interiors

Journal Article Zaghoo, Mohamed ; Silvera, Isaac F. - Proceedings of the National Academy of Sciences of the United States of America

Liquid metallic hydrogen (LMH) is the most abundant form of condensed matter in our solar planetary structure. The electronic and thermal transport properties of this metallic fluid are of fundamental interest to understanding hydrogen’s mechanism of conduction, atomic or pairing structure, as well as the key input for the magnetic dynamo action and thermal models of gas giants. Here, we report spectrally resolved measurements of the optical reflectance of LMH in the pressure region of 1.4–1.7 Mbar. We analyze the data, as well as previously reported measurements, using the free-electron model. Fitting the energy dependence of the reflectance data yieldsmore »« less
