Discovery of 203 K superconducrivity in compressed hydrogen sulfide(H2S)[1] has attracted a great interest on behavior of hydrogen compounds under high-pressure.
We investigate lattice thermal conductivity κ of MgSiO3 perovskite(pv)by ab initio lattice dynamics calculations combined with exact solution of linearized phonon Boltzmann equation.
A novel method for preparing transparent LaGdZr2O7 nanoceramics at relatively low temperatures(400-600℃),i.e.about 70%lower compared with other commonly used preparation methods,has been developed und
We conducted preliminary study on the propagtion of stress wave with phase transition under combined compression-shear loading with the critical criterion proposed by Guo et al[1],which considers both
The spin-orbital entangled state has been discovered in several iridium-oxide systems,which has brought a brand new SOC related physics and attracts a lot of attention.
2D alkylammonium lead iodide perovskites, (RNH3)2(CH3NH3)n-1PbnX3n+1, where R a alkyl or aromatic moiety, e.g., C4H9NH3+ (BA+) and C8H9NH3+ (PEA+), X is a halide ion, e.g., Cl-, Br-, I-; n is the numb
The physical properties of the high-pressure(HP)cubic phase of PbVO3 were investigated by experimental and theoretical studies.PbVO3 exhibits structural transition above 3 GPa from the tetragonal to t
