Polyaniline is a polymer material that has unique physical and even chemical properties, especially in its electrical properties. PANi synthesis can be carried out by electrochemical oxide reaction methods. The purposes of this study are to synthesize / Fe 3 O 4 composites reactions measure their conductivity. This research begins with the iron (Fe ) from natural sand then followed using copret...

The principal aim of this research is the application of Fe3O4 (MNPs) in the synthesis of some indole derivatives. Fe3O4 MNPs were prepared by Co-Precipitation method from the reaction of FeCl2.4H2O and FeCl3.6H2O in ammonia solution. Morphology and structure of Fe3O4 MNPs were determined by FT-IR, X-Ray diffraction (XRD), transmission electron microscopy (TEM) and scanning electron microscopy ...

The public is increasingly exposed to various engineered nanomaterials because of their mass production and wide application. Even when the biological effects of nanomaterials have been assessed, the underlying mechanisms of action in vivo are poorly understood. The present study was designed to seek a simple, effective, and oxidative stress-based biomarker system used for screening toxicity of...

Nitrate is a noxious and persistent oxyanion in drinking waters. It themed as one of the most common water quality violations worldwide. electrocatalytic reduction appears to be viable solution. However, use platinum group elements (PGEs) electrocatalysts must avoided due their high cost limited availability. In this study, earth-abundant nano-Fe3O4 electrodes were synthesized surpass those imp...

Marine concrete structures are subject to the action of multiple environments during their service time. This leads increased deterioration in durability marine concretes under combined bending load and dry–wet cycles, salt freeze–thaw spray erosion. The main reason for damage above three is Cl- attack. free content (Cl-f) diffusion coefficient (Df) can explain concrete. paper considers actual ...

Foodborne illness outbreaks have significantly impacted public health. The contact antibacterial nanomaterials may potential migration of and thus bring safety concerns. In this work, we develop photo-triggered nano-generators for on-demand release essential oil vapor to achieve a non-contact strategy between target bacteria. This nano-generator (Fe3O4@[email protected]/carvacrol, FPZC) is comp...

Magnetic iron oxide (Fe3O4) in nano form has been synthesized by a simple wet chemical method involving co-precipitation using salt and ammonium hydroxide as precipitating agents. Characterization of the nanoparticles were carried out XRD, FTIR, FESEM VSM techniques. Crystallite sizes determined from XRD data found to be between 6.8 12.6 nm with face center cubic crystal structures. The lattice...

In this work, palladium (II) chloride-supported-N-(dipyridine-2-ylmethyl)-3-(silica-magnetite)propan-1-amine (nano-Fe3O4@SiO2@dipy@PdCl2) as a new nanostructured catalyst was prepared and its structure completely studied by different techniques and then successfully tested on Heck and Suzuki reactions.

fe3o4-containing cotton-like mesoporous silica system (fe3o4@ncsm) was studied with regard to its performance towards the photodecolorization of bromothymol blue (btb) aqueous solution. the surface properties of the functionalized catalyst were analyzed by a series of characterization techniques like ftir, xrd, bet, sem and tem. the n2 adsorption–desorption analysis shows that the mesostructure...
