In this study,we have measured extended X-ray absorption fine structure(EXAFS)of CoHx under pressure,and hydrogenation process is discussed by the local structure around Co.
Periclase(MgO)is the compositional end-member of ferropericlase which is believed to be the major end-members of constituent mineral phases of the Earths lower mantle [1].
Olivine(Mg,Fe)2SiO4 with its high pressure polymorphs(β-wadsleyite,γ-ringwoodite)are the main mineral compositions in the upper mantle and the mantle transition zone.
The elastic properties of upper mantle minerals under simultaneous high-pressure and high-temperature conditions are required to interpret the seismic models of Earth.Among different petrologic models
Using multi-anvil high-pressure high-temperature(HP-HT)facilities,we have synthesized singlecrystalline samples of the recently discovered new iron oxide,Fe4O5 [1].Fe4O5 contains equal amounts of Fe2+
High pressure reaction sintering using toroidal-type chambers have been used to produce titanium matrix composites with a boride reinforcement phase,a material class with a high technological interest
Zeolitic imidazolate frameworks,including ZTF7,ZTF62 and ZTF4 have been investigated as a function of temperature and pressure to understand the relationship between their structural stabilities and t
Several hundred ab initio molecular dynamic(MD)simulations have been performed to obtain the pressure-temperature-volume(P-T-V)data of superfluid H2O,CO2,and H2O-CO2 mixtures.
