A novel polyarylene sulfide,polyarylene sulfide sulfone imide,was polymerized with a new monomer(Dichlorodiimide)and sodium sulfide by taking high temperature(2
Polycrystalline samples La0.67-xDyxCa0.3MnO3 (x=0~0.6) were prepared by traditional solid-state reaction method. The magnetization and resistivity of the samples
