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…
Superconductivity at 253 K in lanthanum-yttrium ternary hydrides
Dmitrii V. Semenok, Ivan A. Troyan, Alexander G. Kvashnin +14
Polyhydrides offer intriguing perspectives as high-temperature superconductors. Here we report the high-pressure synthesis of a series of lanthanum-yttrium ternary hydrides: cubic…
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…
Novel hydrogen clathrate hydrate
Yu Wang, Konstantin Glazyrin, Valery Roizen +8
We report a new hydrogen clathrate hydrate synthesized at 1.2 GPa and 298 K documented by single-crystal X-ray diffraction, Raman spectroscopy, and first-principles calculations. T…
Hot Hydride Superconductivity above 550 K
A. D. Grockowiak, M. Ahart, T. Helm +9
The search for room temperature superconductivity has accelerated dramatically in the last few years driven largely by theoretical predictions that first indicated alloying dense h…
Pressure induced lattice expansion and phonon softening in layered
Pinku Saha, Bishnupada Ghosh, Aritra Mazumder +2
We report high pressure X-ray diffraction and a detailed systematic Raman measurements on sample, which is mechanically exfoliated from a single crystal. A few new Bragg pe…
