Spectroscopic, Electrochemical, and Kinetic Trends in Fe(III)–Thiolate Disproportionation Near Physiological pH

, 2023
In addition to its primary oxygen-atom-transfer function, cysteamine dioxygenase (ADO) exhibits an understudied disproportionation reaction (ADO-Fe(III)-SR → ADO-Fe(II) + ½ RSSR) with its native substrates.

Hydrologic Alteration and Enhanced Microbial Reductive Dissolution of Fe(III) (hydr)oxides Under Flow Conditions in Fe(III)-Rich Rocks: Contribution to Cave-Forming Processes

Frontiers in Microbiology, 2021
Previous work demonstrated that microbial Fe(III)-reduction contributes to void formation, and potentially cave formation within Fe(III)-rich rocks, such as banded iron formation (BIF), iron ore and canga (a surficial duricrust), based on field ...

Electrochemical Monitoring of Reduction and Binding of Iron Amyloid-β Complexes at Boron-Doped Diamond Electrode

International Journal of Electrochemical Science, 2012
The amino acid residues for reduction and binding of amyloid–β peptide (Aβ)–Fe(III) complexes were investigated mainly by voltammetry at boron-doped diamond electrodes. Distinguished from natural Fe(III)–Aβ(1–16) complex, the recovering redox behavior of

Reductive reactivity of iron(III) oxides in the east china sea sediments: characterization by selective extraction and kinetic dissolution. [PDF]

PLoS ONE, 2013
Reactive Fe(III) oxides in gravity-core sediments collected from the East China Sea inner shelf were quantified by using three selective extractions (acidic hydroxylamine, acidic oxalate, bicarbonate-citrate buffered sodium dithionite).

New insight into iron biogeochemical cycling in soil-rice plant system using iron isotope fractionation

Fundamental Research, 2021
Iron (Fe) migration in soil-plants is a critical part of Fe biogeochemical cycling in the earth surface system. Fe isotope fractionation analysis in the soil-rice system is promising for quantitatively assessing various pathways and clarifying Fe ...

Dissimilatory Fe(III) Reduction Controls on Arsenic Mobilization: A Combined Biogeochemical and NanoSIMS Imaging Approach

Frontiers in Microbiology, 2021
Microbial metabolism plays a key role in controlling the fate of toxic groundwater contaminants, such as arsenic. Dissimilatory metal reduction catalyzed by subsurface bacteria can facilitate the mobilization of arsenic via the reductive dissolution of ...

Ocean Acidification Effect on the Iron-Gallic Acid Redox Interaction in Seawater

Frontiers in Marine Science, 2022
Ocean acidification impacts the iron (Fe) biogeochemistry both by its redox and its complexation reactions. This has a direct effect on the ecosystems due to Fe being an essential micronutrient.
