Metallic Hydrogen Sublattice and Proton Mobility in Copper Hydride at High Pressure

Thomas Meier, Florian Trybel, Giacomo Criniti +9

Atomic and electronic structures of Cu2H and CuH have been investigated by high pressure NMR spectroscopy, X-ray diffraction and ab-initio calculations. Metallic Cu2H was synthesiz…

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…

Polytypism of Incommensurately Modulated Structures of Crystalline Bromine upon Molecular Dissociation under High Pressure

Yuqing Yin, Andrey Aslandukov, Maxim Bykov +14

Polytypism of incommensurately modulated structures was hitherto unobserved. Here, we found the phenomenon in simple halogen systems of bromine and iodine upon molecular dissociati…

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…

Pressure induced Hydrogen-Hydrogen interaction in metallic FeH revealed by NMR

Thomas Meier, Florian Trybel, Saiana Khandarkhaeva +8

Knowledge of the behavior of hydrogen in metal hydrides is the key for understanding their electronic properties. So far, no experimental methods exist to access these properties b…

Fe0.79Si0.07B0.14 metallic glass gaskets for high-pressure research beyond 1 Mbar

Weiwei Dong, Konstantin Glazyrin, Saiana Khandarkhaeva +5

A gasket is an important constituent of a diamond anvil cell (DAC) assembly, responsible for the sample chamber stability at extreme conditions for x-ray diffraction studies. In th…
