Performance Of Carbon Aerogel/Fiber Paper As Capacitive Deionization Electrodes Under Variable Operating Conditions, Md Ashique Ahmed, Sanjay Tewari
Performance Of Carbon Aerogel/Fiber Paper As Capacitive Deionization Electrodes Under Variable Operating Conditions, Md Ashique Ahmed, Sanjay Tewari
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
The capacitive deionization has garnered renewed interested with recent modifications resulting in efficient (energy and cost) alternatives to desalinate brackish water (salt concentration less than 10 g/L). Recent research efforts, to improve the technology, have been focused mainly on electrode material development and modifications of operational parameters for optimized performance. This research is focused on performance evaluation of carbon aerogel/fiber paper as capacitive deionization electrodes under variable operating conditions. The main operational parameters that were varied are applied voltage, influent temperature and initial concentration. The highest adsorption capacity achieved in this on-going study is 4.61 mg/g at 33.5 oC with …

Phytovolatilization Of Organic Contaminants, Matt Limmer, Joel Gerard Burken
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
Plants can interact with a variety of organic compounds, and thereby affect the fate and transport of many environmental contaminants. Volatile organic compounds may be volatilized from stems or leaves (direct phytovolatilization) or from soil due to plant root activities (indirect phytovolatilization). Fluxes of contaminants volatilizing from plants are important across scales ranging from local contaminant spills to global fluxes of methane emanating from ecosystems biochemically reducing organic carbon. In this article past studies are reviewed to clearly differentiate between direct- and indirect-phytovolatilization and we discuss the plant physiology driving phytovolatilization in different ecosystems. Current measurement techniques are also described, …
