In this study, Zinc Oxide nanoparticles (ZnONPs) were synthesized by chemical method and their antibacterial efficiency against a clinical isolate of Staphylococcus aureus was studied. The Zinc Oxide nanoparticles have shown a commendable inhibition effect on the growth of most notorious bacterial pathogen S.aureus. The nanoparticles size and shapes were characterized by trans...

FePt/iron oxide core/shell nanoparticles are synthesized by a two step polyol process with 1,2hexadecanediol as the reducing reagent. Monodispersed 2.6-nm FePt nanoparticles are first obtained by reduction of iron(III) acetylacetonate and platinum(II) acetylacetonate. These preformed FePt nanoparticles are then used as seeds and an iron oxide shell is formed in the second synthesis step. The ro...

use of zinc and iron oxide are common in the desulfurization process from natural gas. in thisresearch, after determinations of the size and specifications through tem and xrd for each of the metaloxides, two different size ratios were used, 0.66 for zinc oxide and 0.142 for iron oxide. further, absorption of sulfur compounds in gas (hydrogen sulfide (h2s), carbonyl sulfide (cos), methyl mercap...

The iron oxide nanoparticles have been synthesized in co-precipitation method using aqueous solution of ferric and ferrous ions with sodium salt. The synthesis of iron-oxide nanoparticles were validated by UV-Visible spectroscopy which showed higher peak at 370 nm as valid standard reference. An average size of iron oxide nanoparticle found by diffraction light scattering (DLS) particle size an...

Iron oxide impregnated casein nanoparticles (IOICNPs) were prepared by in-situ precipitation of iron oxide within the casein matrix. The resulting iron oxide impregnated casein nanoparticles (IOICNPs) were characterized by Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FTIR), Vibrating sample magnet...

nanotechnology researchers have identified a wide range of nanoparticle applications that may have an important role in medicine and treatment of diseases. due to lack of detailed documentation about the toxicology of zinc oxide (zno) nanoparticles, this study was aimed to evaluate the absorption of zno nanoparticles in hearts of female nmri mice. overall, 20 adult nmri female mice were studied...

iron oxide (fe2o3) is widely used as a catalyst, pigment and gas sensitive material.  in this article, α-fe2o3 nano-rods were first synthesized via a simple chemical method using iron(iii) nitrate 9- hydrate (fe(no3)3.9h2o) as precursor. xrd pattern showed that the iron oxide nanoparticles exhibited alpha-fe2o3 (hematite) structure in nanocrystals. the single-phase α- fe2o3 nano-rods were prepa...

magnetic nanoparticles can bind to different drug delivery systems and can be used for drug targeting to a specific organ by using an external magnetic field as well as used in hyperthermia by heating in alternating magnetic fields. the characteristics of iron oxide nanoparticles are significantly affected by particle size, shape and zeta potential, among which the particle size plays the most ...
