Structural diversity of molecular nitrogen on approach to polymeric states
Alexander F. Goncharov, Iskander G. Batyrev, Elena Bykova +7
Nitrogen represents an archetypal example of material exhibiting a pressure driven transformation from molecular to polymeric state. Detailed investigations of such transformations…
Assessing the stability fields of molecular and polymeric CO2
Alexander F. Goncharov, Elena Bykova, Maxim Bykov +4
We investigated the stability of polymeric CO2 over a wide range of pressures, temperatures, and chemical environments. We find that the I-42d polymeric structure, consisting of a…
Structure and vibrational properties of methane up to 71 GPa
Maxim Bykov, Elena Bykova, Chris J. Pickard +4
Single-crystal synchrotron X-ray diffraction, Raman spectroscopy, and first principles calculations have been used to identify the structure of the high-pressure (HP) phase of mole…
Synthesis and structure of carbon doped H3S compounds at high pressure
Alexander F. Goncharov, Elena Bykova, Maxim Bykov +4
Understanding of recently reported putative close-to-room-temperature superconductivity in C-S-H compounds at 267 GPa demands reproducible synthesis protocol as well as knowledge o…
Structure and composition of C-S-H compounds up to 143 GPa
Elena Bykova, Maxim Bykov, Stella Chariton +7
We synthesized two C-S-H compounds from a mixture of carbon and sulfur in hydrogen and from sulfur in mixed methane-hydrogen fluids at 4 GPa. X-ray synchrotron single-crystal diffr…
Stabilization of hexazine rings in potassium polynitride at high pressure
Yu Wang, Maxim Bykov, Elena Bykova +6
Polynitrogen molecules represent the ultimate high energy-density materials as they have a huge potential chemical energy originating from their high enthalpy. However, synthesis a…
