Zinc sulfide (ZnS) & zinc oxide (ZnO) nanoparticles was evaluated for their antimicrobial activity against four pathogenic strains. ZnS&ZnO nanoparticles were synthesized by simple aqueous chemical reaction in an aqueous solution. The main advantage of these nanoparticles (size of 10-30 nm) was that simply could be prepared by using cheap precursors in a cost effective and high throughput manne...

We present an interdisciplinary overview of material engineering and emerging applications of iron oxide nanoparticles. We discuss material engineering of nanoparticles in the broadest sense, emphasizing size and shape control, large-area self-assembly, composite/hybrid structures, and surface engineering. This is followed by a discussion of several non-traditional, emerging applications of iro...

The special application of iron-manganese oxide nanocatalysts has been investigated in decomposition of hydrogen peroxide. In this research, iron-manganese oxide nanocomposites were synthesized by co-precipitation, sol-gel and mechanochemical methods using iron (III) nitrate, iron (II) sulfate and manganese (II) nitrate as starting materials. These nanocomposites were prepared on the variou...

Recently, there has been a great deal of interest in the use of the medicinal plants with high antioxidant compounds for curing liver injuries induced by hepatoxcitic agents. This study was to assess the protective effect of Carum carvi L. essential oil (E.O) on the hepatoxitic rats induced by overdose of iron oxide nanoparticles (NPs). The rats were distributed to 4 groups. In negative control...

Abstract Zinc ferrite nanoparticles were obtained by chemical methods (co-precipitation and thermal decomposition of metalorganic compounds) systematically probed with volume (XRD, VSM), microscopic (TEM) element sensitive probes (ICP-OES, Mössbauer Spectroscopy, XPS, XAFS). Magnetic studies proved the paramagnetic response stoichiometric ZnFe 2 O 4 (ZF) nanoparticles, while superparamagnetic b...

Recently, magnetic iron oxide particles have been emerged as significant nanomaterials due to its extensive range of application in various fields. In this regard, synthesis of iron oxide nanoparticles with desirable properties and high potential applications are greatly demanded. Therefore, investigation on different iron oxide phases and their magnetic properties along with various commonly u...

This thesis deals with the synthesis, characterisation, and some applications of ferrimagnetic iron oxide nanoparticles. The iron oxide systems presented in this work are Fe3O4, γ-Fe2O3, NixFe3−xO4, CoxFe3−xO4. Iron oxide nanoparticles were prepared using chemical synthesis methods. Nanoparticles with a narrow size distribution were synthesised using zone confinement methods such as nanoemulsio...

In this study, undoped ZnO and doped with Fe and Mn nanostructures were synthesized by hydrothermal method. The morphology of nanostructures was characterized by Scanning Electron Microscope. The electrochemical response of the carbon paste electrode modified with nanoparticles of ZnO and also ZnO doped with Fe and Mn toward levodopa (L-Dopa) was studied. Studies of cyclic voltammetry using pro...
