EDTA-functionalized Fe3O4 nanoparticles Abstract: This study analyzes the synthesis and characterization of functionalized Fe3O4 nanoparticles by ethylenediaminetetraacetic acid (EDTA). The syntheses were performed using the co-precipitation method under different experimental conditions: nitrogen atmosphere versus ambient atmospheric […]
A versatile approach for the preparation of ceramics with porosity gradient: by using manganese and tin oxides as a model Abstract: Porous ceramics that exhibit porosity gradient are considered promising materials from the industrial point of […]
Blue and red light photoluminescence emission at room temperature from CaTiO3 decorated with α-Ag2WO4 Abstract: CaTiO3 (CT) and α-Ag2WO4 (AW) semiconductors are widely known for their interesting electrical and photoluminescence (PL) properties. In this study, we decorated CT with AW […]
