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…
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-pressure structural study of a-Mn: solving a three decades-old mystery
Logan K. Magad-Weiss, Adebayo A. Adeleke, Eran Greenberg +3
Manganese, in the a-Mn structure, has been studied using synchrotron powder x-ray diffraction in a diamond anvil cell up to 220 GPa at room temperature combined with density functi…
A latent heat method to detect melting and freezing of metals at megabar pressures
Zachary M. Geballe, Nicholas Holtgrewe, Amol Karandikar +3
The high-pressure melting curves of metals provide simple and useful tests for theories of melting, as well as important constraints for the modeling of planetary interiors. Here,…
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…
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…
