[ 1 ] - Synthesis and characterization of Pt3Co bimetallic nanoparticles supported on MWCNT as an electrocatalyst for methanol oxidation

The impregnation method was used to synthesize Pt and Pt3Co supported on MWCNTs applying NaBH4 as the reducing agent. The structure, morphology, and chemical composition of the electrocatalysts were characterized through SEM, XRD, and EDX. X-ray diffraction showed a good crystallinity of the supported Pt nanoparticles on the composites and showed the formation of Pt3<...

[ 2 ] - The Effect of Cross-Rolling Process on Nanostructure of Al 1050 Alloy

The cross-rolling is a new process that results in significant evolutions in microstructure of the metallic sheets. In this study, an aluminium 1050 sheet was rolled up to 95% reduction in cross directions for ten passes. The rolled samples were investigated by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The rolled samples possess a high dislocation density and ultra-fin...

[ 3 ] - Green synthesis of Ag/Fe3O4/ZrO2 nanocomposite using aqueous Centaurea cyanus flower extract and its catalytic application for reduction of organic pollutants

In this work, at first, nano ZrO2 and Fe3O4/ZrO2 nanocomposite were prepared by sol-gel and co-precipitation methods, respectively. Then, Ag nanoparticles (Ag NPs) were mixed with themin environmentally friendly and mild conditions using C. cyanus flower extract as a reducing and stabilizing agent. The synthesized nanocomposites were characte...
