Thin films of physical mixture Hausmannite Mn3O4 and lithium (Li) are synthesized by spray pyrolysis technique. Structural, morphological, optical, electrical, wettability, photocatalytic properties have been investigated. X-ray diffraction (XRD) Raman spectra, Scanning electron microscope (SEM) images, electrical measurements show that Li nanoparticles formed both on top surface the film insid...

Manganese oxides were synthesized during 40 min at 140 ºC via Microwave-Assisted Hydrothermal (MAH) method and treated different temperatures in order to evaluate the phase evolution using structure refinement (Rietveld method). The samples obtained heat defined by means of thermal analysis (160 ºC, 480 715 870 920 1150 ºC) analyzed X-Ray Diffractometry (XRD), Fluorescence (XRF), Fourier Transf...
