Trace Element Cycling during Iron(II)-activated Recrystallization of Iron(III) Oxide Minerals
Biogeochemical iron cycling initiates secondary abiotic reactions between aqueous Fe(II) and Fe(III) oxide minerals, which results in dynamic recrystallization via simultaneous Fe(II) oxidative adsorption and Fe(III) reductive dissolution. Fe(III) oxide minerals are abundant in soils, sediments, …

Iron (III) Oxide and Copper (II) Oxide Mediated Formation of PCDD/Fs from Thermal Degradation of 2-MCP and 1,2-DCBz
… constitutes a major toxic component of environmental pollutants. Generally, it is well established that transition metal-mediated reactions account for the majority of PCDD/F emissions from combustion sources. Specifically, both copper and iron ions, which occur abundantly in combustion …

Formation of Environmentally Persistent Free Radicals on the Surface of Iron Oxide and Interior of Montmorillonite Clay
<p>Environmentally persistent free radicals (EPFRs) are a new class of pollutants known to damage the lungs and heart, as well as catalyze the formation of toxic compounds such as dioxins and furans. EPFRs are known to form on metal oxide nanoparticles’ surface, including iron (III) oxide, and …

The catalytic oxidation of manganese in water treatment clarification processes
… The extent of adsorption is determined by pH, iron and manganese concentrations. Manganese adsorption is relatively insensitive to the concentration of other cations and anions present in natural water, although large increases in ionic strength increase the adsorption ratio. As pH and …

Clay mineral catalysed oxidation of phenols
… project was to grow a series of nanoparticulate iron(III) oxides within aluminosilicate clay minerals (Fulacolor™ and bentonite) and employ them as oxidation catalysts for phenolic compounds using hydrogen peroxide as oxidant in Fenton or photo-Fenton processes. Thermal degradation of phenol …

Optimization of Quinone-Based, Extracellular Electron Transfer Mediators for Bioelectronic Applications
… The library was screened in a high-throughput iron(III) oxide nanoparticle reduction assay, and top performers were evaluated in a bioelectronic system (BES). It was found through screening that Ndh2-dependent EET in L. plantarum activity strongly correlates to a mediators' lipophilicity [LogD …

Investigation of Size Specific Fe2O3 nanoparticles: Towards Single Nanoparticle Resolved Spectro-ptychography
… nanoparticle resolved spectro-ptychography. Iron oxide nanoparticles, specifically 𝛼-Fe2O3 were used because they are well characterized, have a sharp core edge, and the ptychography imaging detector is sensitive to X-rays at this energy. Therefore, iron oxide nanoparticles were ideal to …
