Superconductivity up to 243 K in yttrium hydrides under high pressure
P. P. Kong, V. S. Minkov, M. A. Kuzovnikov +9
The discovery of high-temperature conventional superconductivity in H3S with a critical temperature of Tc=203 K was followed by the recent record of Tc ~250 K in the face-centered…
Anomalous high-temperature superconductivity in YH
Ivan A. Troyan, Dmitrii V. Semenok, Alexander G. Kvashnin +16
Pressure-stabilized hydrides are a new rapidly growing class of high-temperature superconductors which is believed to be described within the conventional phonon-mediated mechanism…
Revealing the complex nature of bonding in binary high-pressure compound FeO
E. Koemets, I. Leonov, M. Bykov +21
Extreme pressures and temperatures are known to drastically affect the chemistry of iron oxides resulting in numerous compounds forming homologous series FeOFeO…
B1-B2 phase transition in MgO at ultra-high static pressure
Natalia Dubrovinskaia, Sylvain Petitgirard, Stella Chariton +6
Studies of the behaviour of solids at ultra-high pressures, those beyond 200 GPa, contribute to our fundamental understanding of materials properties and allow an insight into the…
High-pressure synthesis of ultraincompressible hard rhenium nitride pernitride Re(N)N stable at ambient conditions
Maxim Bykov, Stella Chariton, Hongzhan Fei +17
Here we report the synthesis of metallic, ultraincompressible (bulk modulus = 428(10) GPa) and very hard (nanoindentation hardness 36.7(8) GPa) rhenium (V) nitride pernitri…
