[ 1 ] - Green Synthesis of Iron Oxide-Palladium Nanocomposites by Pepper extract and Its Application in Removing of Colored Pollutants from Water
Fe3O4 nanoparticles were synthesized in the presence of pepper extract as a capping agent via a hydrothermal method. Then palladium nanoparticles and Fe3O4-Pd nanocomposites were synthesized with the aid of pepper extract as a reducing agent. Vibrating Sample magnetometer illustrated that Fe3O4 nanoparticles have super paramagnetic behaviour. The photo catalytic behaviour of Fe3O4-Pd nanocompos...
[ 2 ] - Fe-Ag nanocomposite: Hydrothermal preparation of iron nanoparticles and silver dendrite like nanostructures
At the first stage Fe3O4 and Fe nanoparticles were synthesized via a simple hydrothermal method. Then silver nanoparticles and Fe-Ag nanocomposites were synthesized in the presence of NaBH4. The prepared products were characterized by X-ray diffraction pattern, scanning electron microscopy, and Fourier transform infrared spectroscopy. Vibrating Sample magnetometer illustrated that Fe nanopartic...
[ 3 ] - Synthesis and magnetic investigation of cobalt ferrite nanoparticles prepared via a simple chemical precipitation method
In this research cobalt ferrite (CoFe2O4) nano-crystalline powders were prepared by simple chemical precipitation method using cobalt sulfate. The CoFe2O4 nanoparticles were characterized by X-ray diffraction, scanning electron microscopy and Fourier transform infra-red spectroscopy. The crystallite size of CoFe2O4 nanoparticles was calculated by Debye–Scherrer formula. The effect of precursor...
[ 4 ] - Facile preparation of silver nanoparticles and antibacterial Chitosan-Ag polymeric nanocomposites
Silver nanostructures as an effective antibacterial materials were synthesized via three various hydrothermal, sono-chemical and microwave methods using water as a green solvent. Then Chitosan-Ag polymer based nanocomposites were made by a fast chemical procedure. The influence of power, temperature and time on the morphology and particle size of the products was investigated. Scanning electron...
[ 5 ] - Strontium hexa-ferrites and polyaniline nanocomposite: Studies of magnetization, coercivity, morphology and microwave absorption
In this work, the investigation of wave absorption, phase formation, crystal structure and magnetic properties of SrFe12O19 hexa-ferrites nanoparticles that synthesized by co-precipitation using a microwave heating system and polyaniline-SrFe12O19 was carried out by using a combination of vector network analyser (VNA), X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier tra...
