Contaminant Mass Transfer During Boiling In Fractured Geologic Media, Fei Chen
Contaminant Mass Transfer During Boiling In Fractured Geologic Media, Fei Chen

Remediation of fractured geologic media contaminated with chlorinated volatile organic compounds that diffuse into the matrix is challenging using isothermal methods. Due to the low permeability of the matrix material and uncertainty of fracture networks, it is difficult to flush the system with any type of fluid or deliver remediation agents into the matrix. However, thermal methods have some promises. When the matrix is heated above water boiling temperature, depressurization in the fractures may trigger water boiling in the matrix, which, as a result, generates a large volumetric steam flow toward adjacent fractures, stripping the adsorbed or dissolved volatile contaminants …

To date, all attempts to isolate PCB dechlorinators using traditional isolation techniques have failed. In addition, the study of PCB dechlorinating organisms has been hampered because researchers were unable to grow the organisms in sediment-free, defined media. Three microbial species capable of reductive dechlorination of polychlorinated biphenyls have been identified. These three species are from two phylogenetically distinct branches, Dehalococcoides (Bedard et al., 2007) and the DF-1/o-17 group (Wu et al., 2002a; Cutter et al., 2001). The three cultures from which polychlorinated biphenyl dechlorinators have been identified used similar strategies to 'wean' the microbes from the sediments. In this research, …

Retrievals from Earth observation satellites are widely used for many applications, including analyzing dynamic lands and measuring atmospheric components. This research aims to evaluate appropriateness of using satellite retrievals to facilitate understanding characteristics of Southeast Asian (SEA) surface air pollution, attributed to regional biomass burnings and urban activities. The studies in this dissertation focused on using satellite retrievals for 1) mapping potential SEA air pollution sources; which are forests, rice paddies, and urban areas, 2) understanding dynamic optical characteristics of SEA biomass-burning aerosols, and 3) inferring surface ozone level. Data used in this study were from three NASA's Earth Observing …
