Assessing Chemical Dispersants Used During the Deepwater Horizon Oil Spill : Method Innovation and Application

Creator:: Perkins, Matt J.
Abstract:: Large quantities of the chemical oil dispersant Corexit were applied in the Gulf of Mexico (Gulf) in response to the Deepwater Horizon oil spill. Large data gaps regarding the potential transport, persistence and impact of Corexit in the Gulf existed at the time of the emergency response. Analytical methods for...

Interlayer Electronic Interactions in Twisted and Stacked Bilayer Graphene

Creator:: Patel, Hiral
Abstract:: The photophysical properties of two-dimensional (2D) layered van der Waals (vdW) materials, and their heterostructures are manifestly distinct from crystalline bulk materials. Recently, the discovery of new 2D vdW materials and strongly-bound interlayer excitons in these materials has created a new branch in nanoscience. As such, there are a number...

Toward making the invisible visible : studying science teaching self-efficacy beliefs

Creator:: Perkins, Catherine J.
Abstract:: This dissertation consists of two articles to be submitted for publication. The first, a literature review, makes visible common influences on science teaching self-efficacy beliefs and also points to potentially invisible validation concerns regarding the instrument used. The second investigates the participants' invisible science teaching self-efficacy beliefs and, through the...

Expanding the scope of a Diels-Alder approach to biaryl synthesis

Creator:: Schwartz, Johanna Perkins
Abstract:: A Diels-Alder approach to biaryls (DAB) has been applied towards the synthesis of highly substituted, programmable biaryl templates. Tri- and tetra-ortho-substituted biaryls can be produced in just three to four steps from commercially available materials utilizing the Diels-Alder [4+2] cycloaddition. The methods described herein will illustrate the ability of mono...

Model systems for structural investigations into peroxiredoxin catalysis, conformation change, and inactivation

Creator:: Perkins, Arden
Abstract:: Peroxiredoxin (Prx) enzymes catalyze the reduction of hydrogen peroxide, peroxynitrous acid, and organic peroxides, and are extremely efficient peroxidases, with k[subscript cat]/K[subscript M] on the order of 10⁷ - 10⁸ M⁻¹ s⁻¹. Besides their role in oxidative stress defense, evidence has accumulated that some eukaryotes, including humans, use Prxs as...

Effects of disturbance modes on mycorrhizal fungus communities at Crater Lake National Park

Creator:: Trappe, Matt
Abstract:: Crater Lake National Park presents an excellent opportunity for ecological research due to its relatively pristine landscape, the protection of its natural features, its infrastructure, and a Park administration supportive of scientific inquiry and restoration ecology. The research presented here examines the responses of fungi to various forms of perturbation....

Development of a Boiling Surface Effectiveness Parameter by Modeling and Quantifying the Net Coolant Flow Rate

Creator:: Harrison, Matt
Abstract:: Boiling dynamics and related heat transfer mechanisms have been widely studied for several decades. During that time, incredible progress has been made on quantifying bubble departure phenomena including growth rate, departure frequency, associated natural and forced convection, and radiation additions to the overall heat transfer rate. With this, the thermal...

A Regional-Scale Three-Dimensional Susceptibility Model for Enhanced Evaluation of Rainfall- and Seismically-Induced Landsliding

Creator:: Mathews, Nicolas
Abstract:: Shallow landslides are destructive natural hazards that result in widespread losses, both of infrastructure and lives, throughout the world. To help mitigate the impact of landslide hazards, they are commonly characterized across a regional scale by (1) their location and likelihood using susceptibility maps, (2) their magnitude and frequency using...

Synthesis and Solution Characterization of Metal-Oxo Photoresist Precursors

Creator:: Hutchison, Danielle C.
Abstract:: Metal-oxo clusters can be described as soluble pieces of metal-oxide frameworks. Currently, metal-oxo clusters are being considered as solution-based precursors for extreme ultraviolet (EUV, 13.5 nm) photoresist materials, which are a crucial component in the fabrication of microelectronic devices. Two different photoresist precursor systems have been investigated – alkyltin clusters...

The physiology ecology and run diversity of adult Pacific lamprey, Entosphenus tridentatus, during the freshwater spawning migration

Creator:: Clemens, Benjamin J.
Abstract:: Pacific lamprey, Entosphenus tridentatus, have shown recent and rapid declines in abundance. These anadromous fish return to streams where they mature, spawn and die. It has been inferred that Pacific lamprey enter freshwater and reside for ~ 1 year before spawning. This long exposure to the freshwater environment may affect...
