Structural, morphological, electrical, and dielectric properties of the compound SmxSr1-xMnO3, prepared by solid-state reaction and annealed at 650oC for 8 hours, were investigated. X-ray diffraction results showed that the sample has a monoclinic structure with a Sm0.025Sr0.975MnO3 phase. SEM results showed plate-like …

Herein, Co- and Mg-doped CuO nanostructures have been hydrothermally synthesized. The X-ray diffraction technique has been employed for investigating the phase purity and crystal structure, where formation of a typical single phase monoclinic CuO structure has been confirmed. Sharp and intense diffraction …
