Environmental Transformations in Hydrophobicity of TiO2 P-25 Nanoparticles in Alsea River Waters

Creator:: Boenisch, Kylie
Abstract:: Hydrophobic titanium dioxide (TiO2) nanoparticles (NPs) are prevalent in industry and manufacturing. They are known for their white pigmentation, are found in sunscreens, paints, cosmetics, and are frequently used in wastewater treatment. Understanding the physicochemical properties of TiO2 P-25 NPs, such as hydrophobicity, are essential when determining their fate, transport,...

Are they what they eat? A stable GIT microbiome characterized in P. resecata

Creator:: Gustafson, Tarah N.
Abstract:: Intertidal herbivores, such as isopods, help regulate and contribute to nutrient cycling and organic carbon flow through the trophic levels in estuaries and coastal ecosystems. Though much is known about the microbiomes of macrophyte leaves that serve as the primary food source for isopods, and (to a lesser extent) the...

Interface Analysis of Titanium Dioxide and Graphene

Creator:: Frazier, Devon Paige
Abstract:: Titanium dioxide, in the anatase form, is a photocatalyst and has applications in water pollution reduction. Efficiency can be improved with a graphene substrate, which delays electron-hole recombination and may reduce the band gap. In this work, we determine if graphene can also act as a morphactant, changing the shape...

The Crystal Structure of the Potential Drug Target Mycoplasma pneumoniae Glycerol 3-Phosphate Oxidase

Creator:: Palioca, Callia K.
Abstract:: Mycoplasma pneumoniae is the primary cause of community-acquired pneumonias, including what is commonly known as walking pneumonia. This disease affects people from all demographics, but especially children and older adults. Outbreaks are a significant public health concern and work to develop new pharmacological agents is currently being researched. How M....

Examination of Dielectric Properties of BaTiO3-SrTiO3 Based Systems

Creator:: Trobough, Nathaniel D.
Abstract:: This thesis examines the dielectric properties of two systems based on the perovskite materials barium titanate and strontium titanate. A solid solution was created starting with these base materials and then adding varying amounts of bismuth-zinc titanate and sodium niobate. These compositions were calcined and sintered at temperatures determined to...

Peptide Non-planarity Regained

Creator:: Biel, Justin T.
Abstract:: The planar peptide model has guided our understanding and interpretation of protein crystal structures since its origin in the 1950s. It is well understood that deviations from this model occur, but the majority of peptides are planar, as measured by the standard omega torsion angle. Here, we report the first...

Perspectives on a Community Forest : A Practice in Nature Writing

Creator:: Hadella, Lucia C.
Abstract:: The McDonald Forest is one of the Oregon State University Research Forests, owned by the College of Forestry and located approximately seven miles northwest of the heart of Corvallis. I took four hikes on the McDonald Forest at four major recreation destinations: Oak Creek, Dimple Hill, Lewisburg Saddle, and Peavy...

Partial Characterization of the Danio rerio and Xenopus tropicalis MT-‐Ox Enzyme Involved in Gadusol Biosynthesis

Creator:: Roemelt, Taylor
Abstract:: Ultraviolet (UV)-protective compounds, such as mycosporine-like amino acids (MAA) are critical for the survival of marine organisms exposed to high-solar radiation. A chemically similar compound, gadusol, was discovered in eggs of the atlantic cod in 1980, and was originally thought to be derived from MAAs that had been ingested. However,...

Tracking the Range Expansion of a Native Bee, the Squash Bee, Eucera (Peponapis) pruinosa; (Hymenoptera: Apidae) in Oregon using Community Science

Creator:: Jones, Miranda L.
Abstract:: The foraging distance of bees has been intensely studied. In contrast, little is known about the factors that determine bee dispersal distance, especially on large spatial scales. Eucera (Peponapis) pruinosa is a wild ground nesting bee that exclusively collects pollen from squash in the genus Cucurbita. Although the bee occurs...

The Effects of Temperature and Working Electrode Material on the Power Output of a Hydroxymethylfurfural Fuel Cell

Creator:: Breen, Joshua P.
Abstract:: The need for clean energy continues to rise as the earth’s non-renewable resources continue to be depleted to satisfy energy demands. One plausible renewable energy source exists in biomass-powered fuel cells.¹ While there are several ways to convert sugars to energy, one interesting approach is to convert the sugars to...
