Lime application effects on soil aggregate properties: Use of the mean weight diameter and synchrotron-based X-ray mu CT techniques

Creator:: Ferreira, Talita R., Pires, Luiz F., Wildenschild, Dorthe, Brinatti, Andre M., Borges, Jaqueline A. R., Auler, Andre C., and dos Reis, Aline M. H.
Abstract:: The hierarchical organization of aggregates in soil is responsible for the presence of inter and intra-aggregate pores. This research aimed to investigate effects of soil surface liming, considering lime rates of 0, 10 and 15 t ha(-1), on the intra-aggregate porous system of soil aggregates with equivalent diameters of 2-4...

Electronic structure-selectivity trends for electrocatalytic nitrate reduction to ammonium on 3d transition metals

Creator:: Marks, Rylee
Abstract:: Nitrate is a toxic surface and ground water contaminant that poses human-health and ecological hazards. Contamination is anthropogenically sourced to over-amendment of ammonia-based fertilizers, in turn generated by the most carbon intensive chemical process in use today. Electrochemical approaches offer a green alternative to transform harmful waste nitrate into value-added...

Exploring Colloid Transport in Unsaturated Porous Media Using X-Ray Microtomography

Creator:: Brueck, Chris L.
Abstract:: Understanding the mechanisms controlling colloid transport and deposition in the vadose zone is an important step in protecting our water resources. Colloid transport in unsaturated porous media was studied using X-Ray Microtomography (XMT), which is a non-destructive imaging technique that provides three-dimensional images at a resolution on the order of...

Interfacial Relaxation and Two-Fluid Flow in Porous Media: A Fast X-Ray Microtomography Study

Creator:: Meisenheimer, Douglas E.
Abstract:: The flow of multiple immiscible fluids within a porous medium controls many natural and engineered systems in the environment including: geologic CO2 sequestration, enhanced oil recovery from underground reservoirs, and contaminant remediation of groundwater. The need to understand how fluids are transported and distributed in these processes is important for...

Development of an anammox HDH enzyme assay to characterize heavy metal inhibition with protection tests

Creator:: Qiao, Guancheng
Abstract:: Removing nitrogen from wastewater is critical to avoid eutrophication of receiving waters. Due to its potential economic benefits, the use of anammox bacteria to remove nitrogen from wastewater is gaining in popularity. Anammox bacteria utilize NO₂- to oxidize NH₄+ to N₂. However, anammox bacteria are sensitive to a wide variety...

Analyzing the Relationship between Capillary Pressure, Saturation, and Interfacial Area for a Three-Phase Flow System in Porous Media

Creator:: Paustian, Rebecca L.
Abstract:: Multi-phase flow in porous media includes many instances of subsurface flow. Three-phase flow in particular is important in situations of enhanced oil recovery, CO2 sequestration, and groundwater remediation. Many studies have been performed on how two fluid phases (oil/water or air/water) behave in porous media, but very few studies exist...

Multi-Technique Characterizations of Natural and Biomimetic Adhesives

Creator:: Fowler, James E.
Abstract:: There have been many attempts to characterize and mimic natural fluid-based adhesive systems. However, very few of these studies have examined surface or interfacial interactions between adhesive and substrate. Furthermore, until now no study has used a combination of surface analytical and kinematic techniques to determine the precise chemical mechanisms...

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...

Exploration of Simultaneous Anammox and Denitrification (SAD) Biofilm Processes for Nitrogen Removal

Creator:: Hilliard, Richard F.
Abstract:: Anammox (anaerobic ammonium oxidation) bacteria are capable of providing low-cost nitrogen removal for numerous types of wastewaters. However, low growth rates cause long startup-times and inhibition by oxygen and metabolic substrates necessitate close process control to maintain performance. Incorporation of Simultaneous Anammox and Denitrification (SAD) into constructed wetlands could provide...

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...
