Leaching Properties of Estuarine Harbor Sediment Before and After Electrodialytic Remediation [PDF]
, 2007 Electrodialytic remediation (EDR) can be used to extract heavy metals from a variety of different media. In this work, contaminated harbor sediments from two locations in the United States and one in Norway were subjected to EDR, and were compared with ...

Uncertainty Quantification of geochemical and mechanical compaction in layered sedimentary basins [PDF]
, 2017 In this work we propose an Uncertainty Quantification methodology for sedimentary basins evolution under mechanical and geochemical compaction processes, which we model as a coupled, time-dependent, non-linear, monodimensional (depth-only) system of PDEs

pH as a Primary Control in Environmental Microbiology: 1. Thermodynamic Perspective
Frontiers in Environmental Science, 2018 pH influences the occurrence and distribution of microorganisms. Microbes typically live over a range of 3–4 pH units and are described as acidophiles, neutrophiles, and alkaliphiles, depending on the optimal pH for growth.

Modeling pN2 through Geological Time: Implications for Planetary Climates and Atmospheric Biosignatures [PDF]
, 2016 Nitrogen is a major nutrient for all life on Earth and could plausibly play a similar role in extraterrestrial biospheres. The major reservoir of nitrogen at Earth's surface is atmospheric N2, but recent studies have proposed that the size of this ...
