Microwave-Assisted Synthesis and Chemical Modulation of MOF-74(Ni)

Creator:: Aldossary, Abdulrahman N.
Abstract:: Metal-organic frameworks (MOFs) are crystalline porous material distinguished for high free empty volume and pore tunability. MOF-74(Ni) was previously shown to be effective in adsorbing carbon dioxide, methane, and hydrogen. Microwave-assisted synthesis of MOF-74(Ni) was shown to lower reaction time from days to hours. In this thesis, experimental conditions of...

Investigation of MoS2 with Ambient Pressure X-ray Photoelectron Spectroscopy

Creator:: Dardzinski, Derek P.
Abstract:: Molybdenum disulfide (MoS2) has potential applications as a low-cost catalyst for the hydrogen evolution reaction (HER). Defects on MoS2, such as edge sites and sulfur vacancies, are known to be the major active sites for HER. Controlling the formation of these defects allows for the enhancement in reactivity of MoS2...

UV-assisted lipoic acid ligand exchange of copper indium disulfide-zinc sulfide core-shell quantum dots

Creator:: Porth, Lane D.
Abstract:: Water-soluble quantum dots obtained through ligand exchange are widely applicable for biological imaging and marking, LEDs, and photovoltaics. Lipoic acid (LA) was reduced to dihydrolipoic acid (DHLA) using 365-nm soft UV light in a process known as photoligation, and ligand exchange with dodecanethiol-capped CuInS₂-ZnS core-shell quantum dots occurred. The reaction...

Metabolomic Analysis of Oregon Coast Sediment Pore Waters using Ultrahigh Resolution Mass Spectrometry

Creator:: Merlo, James B.
Abstract:: One of the principal drivers of climate change is the concentration of greenhouse gases such as CO2 in the atmosphere. A large portion of this CO2 ends up in the waters off the continental coasts where it transforms into biomass. The major sink for this matter is the ocean sediments...

Reactive Phase Change Materials for Enhanced Thermal Energy Storage

Creator:: Drake, Griffin S.
Abstract:: Effective storage and release of low-to-moderate temperature thermal energy (e.g. solar thermal or geothermal) could be transformational for applications such as space heating/cooling, domestic hot water, or off-grid cooking. Good candidates for thermal energy storage in this temperature range include latent heat storage (LHS) systems and thermochemical energy storage (TCES)...

Environmental Transformations of Nanoparticles in Natural Water Systems using a Hydrophobic and Hydrophilic Dye Assay

Creator:: Turnquist, Macklin C.
Abstract:: Nanoparticles (NPs) are generally defined as particles <100 nanometers (nm) in size in one dimension. Despite increasing industrial usage of TiO2 NPs in sunscreens, cosmetics, and water remediation little is known of their environmental behavior. The primary goal of this research was to develop a rapid method for determining the...

A Fabrication Process and Analysis of ZnO-ZnS-Sb₂S3₃ Thin Film Solar Cells

Creator:: Catherall, David
Abstract:: The purpose of this research is to provide a simple fabrication method for zinc oxide and antimony sulfide based thin film solar cells. Both a ZnO nanorod electron conducting structure and a stibnite absorber show promise in a solar cell. Initial attempts at using only ZnO and Sb2S3, however, resulted...

Surface Structure Sensitivity to Fuel Adsorption on Pt(111) and Pt(100) and Carbon-Oxygen Bond Breakage at the Anode of a Direct Dimethyl Ether Fuel Cell

Creator:: Schneider-Coppolino, Merissa
Abstract:: As conventional energy sources begin to deplete, the need for alternative, renewable energy becomes more necessary. Dimethyl ether (DME) fuel cells are a promising energy source that could fulfill these demands. Compared to well-known fuel cell fuels, such as methanol, DME has a low toxicity and high energy density. Experimental...

The Stability, Toxicity, and Reactivity of Zero Valent Iron Nanoparticles

Creator:: Bulovsky, Hannah G.
Abstract:: Zero valent iron nanoparticles effectively remediate groundwater contaminants due to their catalytic properties and enhanced surface area. However, these properties contribute to particle agglomeration, decreasing their effectiveness. In this study, we examined the effect of two stabilizing agents (gum arabic (GA) and sodium carboxymethyl cellulose (CMC)) on particle stability, toxicity,...

Alteration of flower color in Solanum lycopersicum through ectopic expression of a gene for capsanthin-capsorubin synthase from Lilium lancifolium

Creator:: Jeknic, Stevan
Abstract:: Tomato flowers (Solanum lycopersicum) were used as a model system to investigate flower color modification by alteration of the carotenoid biosynthetic pathway, due to their ease of transformation and short time from seed to flowering. Tomato flowers are naturally bright yellow, primarily due to the accumulation of violaxanthin. Violaxanthin is...
