This work presents Fe3O4 and AgFe nanoparticles with an average diameter of 25 and 15 nm synthesized by chemical reduction of corresponding salts under a mild condition. Cubic crystal structure and spherical shape of the nanoparticles were studied by X-ray diffraction, Field emission SEM and energy-dispersive spectroscopy analysis. For biomedical applications, the nanoparticles were tested against bacteria E.coli and results revealed AgFe nanoparticles
Pulsed plasma in liquid is a simple, ecologically friendly, cost-efficient method based on electrical discharge between two metal electrodes submerged into a dielectric liquid. We synthesized carbon-encapsulated Fe (Fe@C) magnetic nanoparticles with low cytotoxicity using pulsed plasma in a liquid. Body-centered cubic Fe core nanoparticles showed good crystalline structures with an average size between 20 and 30 nm were encapsulated in onion-like carbon coatings with a thickness of 2–10 nm. Thermal gravimetric analysis showed a high stability of the as-synthesized samples under thermal treatme ...Daha fazlası
Pulsed plasma between two Zn rods submerged into aqueous solution of cetyl trimethylammonium bromide (CTAB) and sodium dodecyl sulphate (SDS) surfactants resulted in formation of pure ZnO nanorods, while the pulsed plasma between two Zn rods in water without surfactant yielded a mixture of ZnO and Zn nanoparticles. Carbon coated ZnO nanorods with about 20 nm thickness and 150 nm length were synthesized by this method using different surfactant materials such as CTAB and SDS. Cu nanoparticles of about 10 nm in size were also synthesized by the pulsed plasma in aqueous solution of 0.2 % gelatine ...Daha fazlası
