Implications of the iron oxide phase transition on the interiors of rocky exoplanets Article 11 February 2021 Melting phase relations in Fe–Si–H at high pressure and implications for Earth’s inner core crystallization Article Open access 15 June 2022 Heavy iron isotope composition of iron ...
Chemical-looping combustion (CLC) is a combustion technology with inherent separation of the greenhouse gas CO2. The technique involves the use of a metal oxide as an oxygen carrier that transfers oxygen from the combustion air to the fuel. The use of iron oxide as an oxygen carrier has been...
In this paper, a novel biocompatible magnetic iron oxide nanoparticles/hydrogel was synthesized based on the simultaneous formation of magnetic iron oxide nanoparticles (MION) and hydrogel based on poly (acrylic acid) grafted onto starch (PAA-g-starch). The structural, morphological and magnetic prope...
The geochemical kinetics relation for the conversion of Fe (OH)3(ferrihydrite) and Fe3(OH)8(hydromagnetite) to hematite and magnetite in the abovementioned reactions (2a and 2b, 3a and 3b) merits further explanation. In this regard, the primary phase of the original iron oxide in sediments...
a diffusion process, except for the slow reaction of Pb adsorption on the Fe oxides formed at the initial citrate/Fe(II) MR of 0.1, where the rate-limiting process was evidently a chemical process, which may involve bond breaking between the coprecipitated citrate ligand and Fe oxide. The...

Textile effluents contain dyes that negatively affect water bodies and inhibit photosynthesis by reducing sunlight penetration. This study investigated the adsorption capacity of an iron oxide sorbent immobilised on naturally derived carbon foam for the
The grafting density was estimated using the weight loss (loss-wt) and the surface area of IONPs determined by BET according to the following equation: Mnpolymer corresponds to the weight of polymer grafted. Na is Avogadro’s number and mNP is the mass of polymer-grafted iron oxide ...
Application of A Generalized Rate Equation to the Gaseous Reduction of Iron Oxide A generalized rate equation, based on the assumption that reduction is controlled by both the oxide/metal interfacial area and gas diffusion mechanisms, was applied to pure ferric-oxide pellets pellets of 7.5mm dia ...
