Aromatic-degrading Sphingomonas isolates from the deep subsurface [PDF]
An obligately aerobic chemoheterotrophic bacterium (strain F199) previously isolated from Southeast Coastal Plain subsurface sediments and shown to degrade toluene, naphthalene, and other aromatic compounds (J.

This table of contents illustrates that the mechanism for mitigating Sr segregation depends strongly on the chemistry of the coating layer. HfO2 electrostatically stabilizes the surface by lowering the surface oxygen vacancies, which serve as the driving force for Sr migration. On the other hand, Al2O3 and Fe2O3 react with segregated Sr to form Sr‐Al‐O

The ability of microorganisms to thrive under oxygen-free conditions in subsurface environments relies on the enzymatic reduction of oxidized elements, such as sulfate, ferric iron or CO2, coupled to the oxidation of inorganic or organic compounds.

Biological Effects of Dispersants and Dispersed Oil in Surface and Deep Ocean Species [PDF]
Beginning with the use of industrial-strength detergents, dispersing agents have been employed in spill response for decades. The Corexit series of agents in common use today generally consist of non-ionic and/or anionic surfactants in a solvent base ...

Modeling the Offshore Export of Subantarctic Shelf Waters From the Patagonian Shelf [PDF]
It has been suggested that the Subtropical Shelf Front (STSF) could be a preferential site for the detrainment of Subantarctic Shelf Water (SASW) and related planktonic shelf species onto the open SW Atlantic Ocean.

Microbial ecology of the deep terrestrial subsurface
Abstract The terrestrial subsurface hosts microbial communities that, collectively, are predicted to comprise as many microbial cells as global surface soils. Although initially thought to be associated with deposited organic matter, deep subsurface microbial communities are supported by chemolithoautotrophic primary production, with ...

Polymorph‐Specific Electronic Transduction in WO3 during Molecular Sensing
Metal‐oxide polymorphs with similar surface chemistry can nevertheless exhibit distinct sensing properties. In γ‐ and ε‐WO3, analyte adsorption appears comparable; yet, only ε‐WO3 induces a pronounced lattice electronic perturbation that accommodates charge in sub‐conduction band minimum states.
