FeOOH instability at the lower mantle conditions
E. Koemets, T. Fedotenko, S. Khandarkhaeva +12
Goethite, α-FeOOH, is a major component among oxidized iron species, called rust, which formed as a product of metabolism of anoxygenic prokaryotes (1, 2) inhabiting the Earth from…
B1-B2 phase transition in MgO at ultra-high static pressure
Natalia Dubrovinskaia, Sylvain Petitgirard, Stella Chariton +6
Studies of the behaviour of solids at ultra-high pressures, those beyond 200 GPa, contribute to our fundamental understanding of materials properties and allow an insight into the…
Evidence for pressure induced polarization rotation, octahedral tilting and reentrant ferroelectric phase in tetragonal (Pb0.5Bi0.5)(Ti0.5Fe0.5)O3
Pragya Singh, Chandan Upadhyay, Zuzana KonÔpková +2
Despite the technological significance of the tetragonal PbTiO3 for the piezoelectric transducer industry, its high pressure behaviour is quite controversial as two entirely differ…
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…
