Bioremediation of chlorinated ethanes and ethenes in vertical flow engineered wetland systems
Sustainable treatment of chlorinated ethanes and ethenes contaminated groundwater using vertical flow engineered wetland systems were investigated in microcosm and column studies. Experiments on environmental and biogeochemical factors that affect system performance were conducted, and a numerical …

Model Chromia Surface Chemistry: C<sub>2</sub> Alkyl Fragment Reactions and Probe Molecule Interactions
The thermally induced reaction of chlorinated ethanes on the nearly-stoichiometric α-Cr₂O₃ (102) surface results in the formation of gas phase hydrocarbons including ethylene, ethane, acetylene, 2-butene, 2-butyne and dihydrogen, and deposition of surface chlorine adatoms. No surface carbon or …

Mathematical Modeling of Reductive Transformation Kinetics of Branched Degradation Pathways of Groundwater Contaminants
… such as chlorinated ethenes, chlorinated ethanes and nitroaromatic explosive compounds (e.g. 2,4,6-Trinitrotoluene (TNT)) degrade in the subsurface primarily by microbially catalyzed reductive transformation reactions. From a regulatory point of view, the capability to simulate the …

Towards next-generation degradable polymers via double amplification
… in order to synthesize tris(aminomethyl)ethanes from pentaerythritol. The result was a scalable, azide free route that produced tris(aminomethyl)ethanol as the trihydochloride salt in high yield. In addition to this approach, a novel route was explored beginning from hexamine to …
