Ultra-fast yttrium hydride chemistry at high pressures via non-equilibrium states induced by x-ray free electron laser
Emily Siska, G. Alexander Smith, Sergio Villa-Cortes +24
Controlling the formation and stoichiometric content of desired phases of materials has become a central interest for the study of a variety of fields, notably high temperature sup…
Ethane and methane at high pressures: structure and stability
Elissaios Stavrou, Alexander A. Maryewski, Sergey Lobanov +4
We have performed a combined experimental and theoretical study of ethane and methane at high pressures up to 120 GPa at 300 K using x-ray diffraction and Raman spectroscopy and th…
Theoretical and experimental evidence of a site-selective Mott transition in Fe2O3 under pressure
E. Greenberg, I. Leonov, S. Layek +6
We provide experimental and theoretical evidence for a novel type of pressure-induced insulator-metal transition characterized by site-selective delocalization of the electrons. Mö…
Synthesis of Polar Ordered Oxynitride Perovskite
Muhtar Ahart, Maddury Somayazulu, Rajasekarakumar Vadapoo +5
For decades, numerous attempts have been made to produce polar oxynitride perovskites, where some of the oxygen are replaced by nitrogen, but a polar ordered oxynitride has never b…
Melting of B12P2 boron subphosphide under pressure
Vladimir L. Solozhenko, Vladimir A. Mukhanov, Petr S. Sokolov +3
Melting of boron subphosphide (B12P2) to 26 GPa has been studied by in situ synchrotron X-ray powder diffraction in a laser-heated diamond anvil cell, and by quenching and electric…
Pressure, stress, and strain distribution in the double-stage diamond anvil cell
Sergey S. Lobanov, Vitali B. Prakapenka, Clemens Prescher +5
Double stage diamond anvil cells (DAC) of two designs have been assembled and tested. We used a standard symmetric DAC as a primary stage and CVD microanvils machined by a focused…
Backbone NxH Compounds at High Pressures
Alexander F. Goncharov, Nicholas Holtgrewe, Guangrui Qian +11
Optical and synchrotron x-ray diffraction diamond anvil cell experiments have been combined with first principles theoretical structure predictions to investigate mixed N2 and H2 u…
Unexpected stable stoichiometries of sodium chlorides
Weiwei Zhang, Artem R. Oganov, Alexander F. Goncharov +7
Sodium chloride (NaCl), or rocksalt, is well characterized at ambient pressure. Due to the large electronegativity difference between Na and Cl atoms, it has highly ionic chemical…
Unexpected stable stoichiometries of sodium chlorides
Weiwei Zhang, Artem R. Oganov, Alexander F. Goncharov +5
At ambient pressure, sodium, chlorine, and their only known compound NaCl, have well-understood crystal structures and chemical bonding. Sodium is a nearly-free-electron metal with…
