The mobilization of heavy metals from contaminated soil using low molecular weight organic acids

Creator:: Kang, Sun Ki
Abstract:: More than 30,000 potential Superfund sites have been identified. Heavy metals are contaminants at many of these Superfund sites. The average cost of cleanup a single-typical Superfund site currently stands at $20 million, and it is expected that the cost may escalate to $50 million within the next decade. Problems...

Hydrogen Interaction with Platinum and Palladium Surfaces

Creator:: Boechler, Amanda N.
Abstract:: Platinum and palladium surfaces are utilized as catalytic surfaces in the chemical industry. Understanding how hydrogen atoms interact with the metal surfaces will allow for further advancement in this area. Specifically, the interaction of hydrogen on the surface and subsurface of these metals was investigated using density functional theory calculations...

Design of a heat exchanger network to challenge controller design methods

Creator:: Pashak, Jeffrey J.
Abstract:: A simple heat exchanger network has been studied as an example of a dynamically interactive process. The process is relatively simple, requiring only temperature measurements and flow rate manipulations. Equations are presented for the design of a physical process having a specified steady-state Relative Gain Array and specified dynamic characteristics....

Aerobic cometabolism of chlorinated aliphatic hydrocarbons by a butane-grown mixed culture : transformation abilities, kinetics and inhibition

Creator:: Kim, Young
Resource Type:: Dissertation
Full Text:: . Williamson and Dr. Gregory Rorrer for their helpful input. I would also like to thank Dr. Mark Dolan for his

Lead-user research in the wood window value chain

Creator:: Kamke, Kathryn Jean
Abstract:: Lead-user research is a relatively new marketing research technique, and it has not seen much use in the forest sector. Lead-user research is designed to capture not just the needs of the customer in their own voice but also to involve actual users of goods and/or services in their development....

Suspect Screening of Hydrocarbon surfactants in AFFFs and AFFF-Contaminated Groundwater by High Resolution Mass Spectrometry

Creator:: Garcia, Raymmah A.
Abstract:: Aqueous film forming foams (AFFFs) are proprietary mixtures containing hydrocarbon surfactants and per-and polyfluoroalkyl substances (PFASs) that are used to extinguish hydrocarbon-based fuel fires. There is limited information on hydrocarbon surfactants in AFFFs and AFFF-contaminated groundwater even though they are more abundant (5-10% w/w) than PFASs (0.9-1.5% w /w) in...
Resource Type:: Masters Thesis

Techno-economic analysis of algal lipid fuels

Creator:: Xiang, Xuwen
Abstract:: A techno-economic analysis (TEA) was performed to evaluate the technology, cost, and resource use for algal biofuel production based on today’s economics and technology. The basic goal of this study is to develop a model to calculate the mass and energy balances and costs to produce 10 million gal of...

An investigation of chitosan for sorption of radionuclides

Creator:: Holfeltz, Vanessa Elaine
Abstract:: Chitosan is a biopolymer resulting from the deacetylation of chitin, the second most abundant biopolymer in nature. Chitosan has been successfully used in systems to remove metal ions and other pollutants from wastewater. Chitosan has shown promise as a sorbent for radionuclides in some aqueous waste streams. The sorption of...

Selective self-assembly of biogenic silica assisted by layer-by-layer deposition and inkjet printing

Creator:: Wang, Wei
Abstract:: Nature is an inspirational source of silica structures that possess unique optical properties. A few classes of organisms fabricate metal oxides with nanoscale features by a bottom-up self assembly process. In particular, diatoms are a prolific class of single-celled algae that possess silica shells or “frustules” with intricate submicron scale...

Fabrication and characterization of ferrimagnetic film for RF/microwave crosstalk suppression

Creator:: Su, Yu-Wei
Abstract:: The primary goal of this thesis is to fabricate a magnetic film between the coplanar transmitted stripline for crosstalk suppression. Crosstalk is caused from undesired inductive and capacitive coupling of signals between two conductors. The effective crosstalk suppression results from the inductive coupling of circuit elements through the lossy properties...
