Rheological Techniques in Characterization and Aiding in the Modification of Soft Matter

Creator:: Daalkhaijav, Uranbileg
Abstract:: Soft matter encapsulates a large array of materials ranging from electronics, plastics, and cosmetics to the biofluids making up all organisms. One of the most important properties of these materials that dictate their functionality is their rheology, which is the flow and deformation behavior in response to stress. The focus...

Production of biohydrodeoxygenated diesel in a novel microscale reactor : Experiments and modeling

Creator:: Atadana, Frederick Williams
Abstract:: Microscale reactors operate in sub millimeter space dimensions. Their small length scale enables process intensification of mass, heat and momentum transport that influence reaction rates. Hence it's possible to observe the true intrinsic reaction kinetics occurring for a set of reactions. In this work a novel microscale reactor for producing...

Removing Chemical Oxygen Demand (COD) Assay Interference from Landfill Leachate Samples Treated with Fenton's Reagents

Creator:: Palmer, Matthew
Abstract:: Incompatibility between Fenton’s Reagents and a potassium dichromate COD test provides interference that prevent accurate measurements of the concentration of organics from oxidized samples. Several treatment options were tested to remove this interference. Oxidation of reagents was eliminated as a potential method for removal of interference due to sample contamination....

The effect of coagulation conditions on floc size distribution and morphology : implications for downstream treatment processes

Creator:: Maguire, Ian R.
Abstract:: Coagulation and flocculation are commonly used in drinking water treatment as a means of destabilizing and aggregating particles and promoting adsorption of dissolved organic carbon (DOC). In practice, jar tests are used to determine optimal conditions for the removal of turbidity and DOC. However, beyond the inferences that can be...

Reversible Covalent Immobilization of Desferrioxamine B (DFOB) on Aminated Polystyrene Beads for Citrate-Bound Fe(III) Chelation

Creator:: Touma, Jad G.
Abstract:: The immobilization of chelators to solid supports has recently gained renewed interest due to the increasing biomedical and environmental applications made possible by these molecules’ ability to bind Fe(III) and other metal ions. The uses of immobilized chelators have expanded to include the treatment of metal overload in serum, the...

Photocatalytic Treatment of Stormwater Runoff using Puralytics LilyPad

Creator:: Laurance, Jon
Abstract:: Stormwater picks up pollutants as it flows over impervious surfaces before ending up in water resources. Best management practices are implemented to remove pollutants from stormwater. Puralytics manufactures a stormwater treatment product called the LilyPad. The LilyPad consists of a titanium dioxide nanoparticle photocatalyst immobilized on polypropylene substrate. Treatment of...

The effects of engineered coatings and natural organic matter on nanoparticle aggregation

Creator:: McDowell, Shannon A.
Abstract:: In order to better predict the aggregation state of nanomaterials, the factors that influence aggregation must be understood. The combined effects of natural and engineered coatings have been shown to factor into nanoparticle aggregation behavior in preliminary research. In this study, aggregation behaviors of gold nanoparticles with two different engineered...

Comparison of Experimentally-determined and Model-estimated Attachment Efficiency for Predicting Nanoparticle Aggregation

Creator:: Kennard, Jasmin J.
Abstract:: The widespread use of engineered nanoparticles (ENPs) in industrial applications and consumer products makes their release to the environment inevitable. Understanding the aggregation behavior of ENPs is crucial to understanding their fate, transport and toxicology in aquatic systems. This study investigated the comparability of experimentally-determined and model-estimated attachment efficiencies for...

Production of biodiesel from soybean oil in a micro scale reactor

Creator:: Al-Dhubabian, Ahmad A.
Abstract:: Biodiesel has become a more attractive fuel in recent years because of its environmental benefits and the fact that it is made from renewable resources. More importantly, biodiesel is becoming economically attractive with the current oil prices which are expected to stay high in the future. Currently, biodiesel is produced...

Heat and mass transfer in Kroll process titanium sponge during salt evaporation

Creator:: Hill, S. D.
Abstract:: Laboratory experiments were conducted to study those factors which control the rate at which salts, such as magnesium chloride and sodium chloride, are removed from titanium sponge. The sponge was prepared by reducing titanium tetrachloride with either magnesium or sodium, and the resulting sponge salt mixtures were treated by vacuum...

Effect of cosputtered catalyst on growth and alignment of carbon nanotubes by plasma enhanced chemical vapor deposition

Creator:: Gunderson, Eric P.
Abstract:: The effect of cosputtered catalyst on growth and alignment of carbon nanotubes (CNTs) grown by plasma enhanced chemical vapor deposition (PECVD) was investigated. Aligned CNTs were observed using a cosputtered catalytic metal deposited directly on boro-aluminosilicate glass. Catalytic metal alloys were sputtered directly onto the substrate using magnetron sputtering. Deposition...

Inhibition, gene expression and modeling of ammonia oxidation in biofilms of Nitrosomonas europaea

Creator:: Lauchnor, Ellen Grace
Abstract:: This dissertation explores the physiology and gene expression of the ammonia-oxidizing bacterium Nitrosomonas europaea in surface-associated bacterial communities, or biofilms. Biofilms of N. europaea were cultivated in drip flow reactors for several weeks and gene expression microarrays were used to detect 240 genes differentially expressed between the mature biofilms and...

Experimental and numerical analysis of transport in saturated heterogeneous media

Creator:: Harrington, Stephanie J.
Abstract:: The conventional advection-dispersion equation cannot adequately describe all processes driving solute transport in heterogeneous systems. This dissertation focuses on the individual influences of both chemical (Chapter 2) and physical processes (Chapters 3 and 4) which affect solute transport. In Chapter 2 we analyzed uranium transport in natural sediment using the...
