Iron (Fe) is the fourth most abundant element in the earth's crust and plays important roles in
both biological and chemical processes. The redox reactivity of various Fe (II) forms has …

Mixed-valent iron [Fe (II)-Fe (III)] minerals such as magnetite and green rust have received a
significant amount of attention over recent decades, especially in the environmental …

Iron-based materials, as a series of effective persulfate (PS) activators, have been utilized
extensively in PS-based advanced oxidation processes. However, there are some ambiguity …

Magnetite nanoparticles (MNPs) are ubiquitous components of the subsurface environment,
and increasing attention has been paid to MNPs due to their highly reductive and …

Using the isotope specificity of 57Fe Mössbauer spectroscopy, we report spectroscopic
observations of Fe (II) reacted with oxide surfaces under conditions typical of natural …

Energetic materials comprise both explosives and propellants. When released to the
biosphere, energetics are xenobiotic contaminants which pose toxic hazards to ecosystems …

Herein, a multifunctional magnetic β-cyclodextrin/graphitic carbon nitride catalyst (Fe 3 O
4@ β-CD/gC 3 N 4) was fabricated for PCBs degradation in wastewater. The catalysts were …

Electroactive microorganisms, which possess extracellular electron transfer (EET)
capabilities, are the basis of microbial electrochemical technologies (METs) such as …

Results from enriched 57Fe isotope tracer experiments have shown that atom exchange can
occur between structural Fe in Fe (III) oxides and aqueous Fe (II) with no formation of …

While most published studies used buffers to maintain the pH, there is limited knowledge
regarding the reactivity of nanoscale zerovalent iron (NZVI) in poorly buffered pH systems to …
