In this paper, the magnetite nanoparticles have been successfully synthesized by using a new water cores of water-of-oil (W/O) microemulsion method. The structure and composition of particles are characterized by XRD and FTIR, which shows the sample is composed of magnetite. TEM image shows ...
Hematite (α-Fe2O3) and magnetite (Fe3O4) nanowires with the diameter of about 100 nm and the length of tens of micrometers have been selectively synthesized by a microemulsion-based method in combination of the calcinations under different atmosphere. The effects of the precursors, annealing...
Iron oxide is a mineral compound that shows different polymorphic forms, including hematite (α-Fe2O3), magnetite (Fe3O4) and maghemite (γ-Fe2O3). Solid propulsion technology nanoparticulate materials, such as hematite and maghemite, exhibit high performance on thermal decomposition of ammonium ...

Periodontitis, one of the most prevalent dental diseases, causes the loss of bone and gum tissue that hold teeth in place. Several bacteria, commonly present in clinically healthy oral cavities, may induce and perpetuate periodontitis when their concentr
Superparamagnetic magnetite nanoparticles (MNPs) were prepared via improved chemical co-precipitation method [26]. According to this method, 3.17 g of FeCl2 · 4H2O (0.016 mol) and 7.68 g of FeCl3 · 6H2O (0.008 mol) were dissolved in 50 ml of deionized water, su...
self-assembly of magnetic nanoparticles and a surface-priming copolymer polystyrene-block-poly(acrylic acid) (PS-b-PAA) in aqueous medium, followed by an easy silanization reaction with a silane precursor MPTMS to grow a silica shell on the interface of magnetite micelles at ambient temperature. ...

chitosan loaded with ZnO nanoparticles showed stronger antimicrobial activity againstE. coliandS. aureusthan the activities recorded by chitosan without modification [60]. Moreover, the activity of composite magnetite/guar gum/chitosan to inhibit the growth of Gram-positive and Gram-negative bacteria was...
Silica-Coated Magnetite nanoparticles (SMNP) recently gained much attractions in biomedical, environmental, construction and nuclear applications. SMNP can overcome the limitations of bare magnetic iron oxide nanoparticles (MNP) such as agglomeration, dissolution and leaching in aqueous and biological ...
