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.
Experimental methods to permit dynamic x-ray diffraction measurements,with picosecond temporal resolution,in laser experiments were developed and used to examine lattice deformation in shocked aluminu
Shock wave action combined with shock-induced chemical reaction and phase transition in materials can lead to their obvious changes of physical and chemical properties.
Poor transport critical current density,jc,is a limiting factor for future applications of polycrystalline high-Tc superconductors,where jc is strongly depressed by grain boundary weak links.
