The oxidation balance is arguably one of the most important parameters during pyrometallurgical processes. In many cases, iron abundant multivalent element present in silicate slags. Within these molten oxide mixtures, oxygen dominated by relative fractions Fe3+ and Fe2+ present. Measuring concentration ferrous ferric quenched slags can provide useful information about state liquid slag at mome...

In order to investigate the effect of magnesium oxide (MgO) and iron oxide (Fe2O3) ‎nanoparticles (NPs) on physiological traits and the yield of sour tea (Hibiscus Sabdariffa L.), a ‎factorial experiment was conducted in a randomized complete block design (RCBD) with four ‎replications in 2018. MgO and Fe2O3 were used in concentrations of 0.01% and 0.03% as foliar ‎application. The results show...

Iron oxide nanoparticles (IONPs) are chemically inert materials and have been mainly used for imaging applications and drug deliveries. However, the possibility whether they can be used as therapeutic drugs themselves has not yet been explored. We reported here that Fe2O3 nanoparticles (NPs) can protect hearts from ischemic damage at the animal, tissue and cell level. The cardioprotective activ...

Sol-gel thin films containing Fe2o3 were deposited onto glass substrates by the dip-coating method at room temperature. Fe2O3 enriched with the isotope 57Fe was embedded in two kinds of matrices: zinc oxide (ZnO) and silica (SiO2). X-ray diffraction (XRD) was used for morphology and structure determination of the nanostructures and showed that the ZnO exhibit a wurtzite form when the film is an...

Recently Fe2O3 NPs (iron oxide nanoparticles) have been extensively used in medical imaging and in industry also. As a result, people are increasingly exposed day by day to those nanoparticles. The adverse effect of Fe2O3 NPs is not so significant at lower doses but at higher doses Fe2O3 NPs causes significant damage to cells. The present study investigates the cell signaling mechanism of Fe2O3...

Nanostructured Iron Oxide with different morphologies of rod-like and granular have been suc-cessfully prepared via a solid-state reaction in the presence of NaCl, NaBr, NaI and NaN3, respectively. The added salts not only prevent a drastic increase in the size of the products but also provide suitable conditions for the oriented growth of primary nanoparticles. The formation mechanisms of thes...

Iron (III) oxide (Fe2O3) is an excellent material for absorbing visible light from the solar spectrum because of its suitable band gap. However, due to low mobility and high bulk carrier recombination, the photoconversion efficiency of iron (III) oxide has been proven to be very poor. Fabrication of nanostructured iron oxide can potentially compensate for the material’s poor properties. In this...

The magnitude and temperature-sensitivity of oxygen isotope fractionation in ferric oxide-water systems remain uncertain. In this study, three different synthetic methods are used to investigate the temperature dependence of the fractionation between water and hematite, akaganeite, and goethite at near-surface temperatures. Our results reveal two similarities among these ferric oxide-water syst...

In this experimental work, Manganese oxide (MnO2), Zinc oxide (ZnO), Iron oxide (Fe2O3) and Magnesium chloride (MgCl2) were used as activating flux to investigate the effects for SS 304 in tungsten inert gas (TIG) welding. Ultimate tensile strength, percentage elongation, Penetration depth and width were studied of material SS 304. The experimental results indicated that the MnO2 and Fe2O3 flux...

Iron oxide (Fe2O3) nanoparticles were synthesized by a simple approach using sodium borohydride (NaBH4) and Iron chloride hexahydrate (FeCl3.6H2O). Their physicochemical properties were characterized by high resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM), X-ray diffraction (XRD) and electron dispersive spectroscopy (EDS). XRD pattern showed that the iron...
