Organic carbon-rich sediments are enriched in several redox-sensitive and stable sulfide-
forming trace metals (TM) and form an important sink in global TM cycles. In today's ocean …

Abstract Sulfate-reducing bacteria (SRB), a group of anaerobic prokaryotes, can use sulfur
species as a terminal electron acceptor for the oxidation of organic compounds. They not …

Biomineralization is a critical process controlling the biogeochemical cycling, fate, and
potential environmental impacts of heavy metals. Despite the indispensability of extracellular …

We measured solid-phase Mo and U concentrations in marine sediments from the
California, Mexico, Peru, and Chile margins to ascertain the behavior of Mo and U during …

Given the scale of the contamination associated with 60 years of global nuclear activity, and
the inherent high financial and environmental costs associated with invasive physical and …

Biological reduction of soluble uranium from U (VI) to insoluble U (IV) coupled to the
oxidation of an electron donor (hydrogen or organic compounds) is a potentially cost …

Abstract 230Th normalization is a valuable paleoceanographic tool for reconstructing high‐
resolution sediment fluxes during the late Pleistocene (last~ 500,000 years). As its …

The sandstone-hosted Qianjiadian uranium deposit, hosted in the Upper Cretaceous Yaojia
Formation in the Qianjiadian area, Songliao Basin, NE China, has been studied for over …

We have used scaling kinetics and the concept of kinetic competence to elucidate the role of
hemeproteins OmcA and MtrC in iron reduction by Shewanella oneidensis MR-1. Second …

Flow-through sediment column experiments examined the reoxidation of microbially
reduced uranium with either oxygen or nitrate supplied as the oxidant. The uranium was …
