surface charges ( 20.8 mV) outperformed the other iron oxide samples having different morphologies like hexagonal ( 13.8 mV), oval ( 13.4 mV), and agglomerated nanoparticles (+ 12 mV) in the methylene blue degradation with ~ 86% of degradation observed for a very low catalyst loading of 10...
Iron oxides, composed of two of the most abundant elements in the Earth’s interior, are fundamentally important materials both for basic science and applied technologies1. The first-known magnetic mineral, magnetite (Fe3O4), was the only simple mixed-valent iron oxide known until recently, and...
Phase transitions that occur in materials, driven, for instance, by changes in temperature or pressure, can dramatically change the materials’ properties. Discovering new types of transitions and understanding their mechanisms is important not only from
Kinetic Monte Carlo model of charge transport in hematite (α-Fe2O3) into iron oxide minerals via abiotic and biotic electron transfer processes is one of the key factors that control the reductive dissolution of such ... S Kerisit,KM Rosso - 《Journal of Chemical Physics》 被引量: 70发表...
Significant reductions in interstitial iron (Fei) concentrations occur during annealing Fe-containing silicon wafers with silicon nitride films in the temperature range of 250°C–700°C. The silicon nitride films are known to release hydrogen during the annealing step. However, in co-annealed samples...
The oxidation state of a transition metal in a crystal lattice is conventionally viewed as reflecting physical ionization: electrons have been transferred to or from the atom, leaving a point-like charged entity (ion). Such a picture is still sometimes i

A blended charge for use as a decarburizing addition to a steelmaking batch comprises 50 to 95% by weight of an iron-carbon alloy and 5 to 50% by weight oxide material. The oxide material includes free metal oxides in excess of 0.25% by ... GA Dorofeev,SZ Afonin,YV Utkin,... - ...
