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…

High-temperature superconductivity on the verge of a structural instability in lanthanum superhydride

Dan Sun, Vasily S. Minkov, Shirin Mozaffari +5

A possibility of high, room-temperature superconductivity was predicted for metallic hydrogen in the 1960s. However, metallization and superconductivity of hydrogen are yet to be u…

High-pressure synthesis of Dirac materials: layered van der Waals bonded BeN polymorph

Maxim Bykov, Timofey Fedotenko, Stella Chariton +17

High pressure chemistry is known to inspire the creation of unexpected new classes of compounds with exceptional properties. Here we report the synthesis at ~90 GPa of novel beryll…

High-pressure polymeric nitrogen allotrope with the black phosphorus structure

Dominique Laniel, Bjoern Winkler, Timofey Fedotenko +6

Studies of polynitrogen phases are of great interest for fundamental science and for the design of novel high energy density materials. Laser heating of pure nitrogen at 140 GPa in…

Novel rhenium carbides at 200 GPa

Saiana Khandarkhaeva, Timofey Fedotenko, Maxim Bykov +7

Laser heating of rhenium in a diamond anvil cell to 3000 K at about 200 GPa results in formation of two previously unknown rhenium carbides, hexagonal WC-type structured ReC and or…
