Geochemical controls of the microbially mediated redox cycling of uranium and iron
(Georgia Institute of Technology, 2018-04-05)
Mining and processing of uranium ore, followed by improper disposal and aging nuclear waste infrastructure, have left behind a legacy of uranium contamination across the United States. Uranium bioreduction, an in situ ...
The biogeochemical source and role of soluble organic-Fe(III) complexes in continental margin sediments
(Georgia Institute of Technology, 2014-09-10)
In the past couple of decades, the discovery that iron is a limiting nutrient in large regions of the ocean has spurred much research into characterizing the biogeochemical controls on iron cycling. While Fe(II) is soluble ...
Soluble organic-Fe(III) complexes: rethinking iron solubility and bioavailability
(Georgia Institute of Technology, 2011-11-22)
The bioavailability of iron is limited by the solubility of Fe(III) at circumneutral pH. In the High Nutrient-Low Chlorophyll (HNLC) zones of the ocean, the natural or anthropogenic addition of iron stimulates primary ...
Importance of manganese oxides in carbon remineralization in river-dominated continental margins and the biogeochemical cycling of arsenic
(Georgia Institute of Technology, 2020-03-25)
Manganese oxides (MnO2) are ubiquitous in the environment and play an important role in the transformation and transport of contaminants in the environment and the biogeochemical cycling of carbon. This study investigated ...
