Observation of high-temperature superconductivity in compressed sulfur hydrides has generated an irresistible wave of searches for new hydrogen-containing superconductors.
A -200 K superconducting phase in dense hydrogen sulfide is an important milestone for the searching novel superconductor with high critical temperature [1,2].
Decreasing the sintering temperature is an effective method to inhibit the diamond particles grew up during the synthesis of PCD,but the composites sintered at low temperature have low bending strengt
High-pressure structures of tantalum hydrides were investigated over a wide pressure range of 0-300 GPa by utilizing the evolutionary structure searches.
The high pressure structural behavior of transition metal dichalchogenides NbSexTe2-x(x=2,1.5)was investigated using powder X-ray diffraction technique and a diamond anvil cell.
