Isostructural phase transition and equation of state of type-I and type-VIII metallic sodium borosilicide clathrates
M. Demoucron, S. Pandolfi, Y. Guarnelli +10
Electronic properties of silicon-based clathrates can be tuned by boron incorporation into the silicon cage network. Sodium borosilicides clathrate outstands with uncommon stoichio…
Phase-channel dynamics reveal the role of impurities and screening in a quasi-one-dimensional charge-density wave system
M. D. Thomson, K. Rabia, F. Meng +3
We investigate the low-energy phase excitations of the quasi-one-dimensional charge density wave (CDW) in , by direct probing of infrared-a…
Revealing the complex nature of bonding in binary high-pressure compound FeO
E. Koemets, I. Leonov, M. Bykov +21
Extreme pressures and temperatures are known to drastically affect the chemistry of iron oxides resulting in numerous compounds forming homologous series FeOFeO…
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 fro…
Thermal expansion and compressibility of monogermanides of 3d-metals
G. A. Valkovskiy, E. V. Altynbaev, M. D. Kuchugura +10
Synchrotron diffraction as a function of temperature and pressure, specific heat, magnetic susceptibility and small-angle neutron scattering experiments have revealed an anomalous…
Superconductivity with Tc 116K discovered in antimony polyhydrides
K. Lu, X. He, C. L. Zhang +15
Superconductivity (SC) was experimentally observed for the first time in antimony polyhydride. The diamond anvil cell combined with laser heating system was used to synthesize the…
