The perovskite-type AgTaO3 crystals were prepared by mild hydrothermal method and determined by powder X-ray diffraction. Rietveld refinement indicates that AgT
A facile method for the synthesis of 2,3,3',4'-biphenyltetracarboxylic dianhydride(a-BPDA) was reported,which comprises the steps of the dehalogenative
