Advanced Solvent Purification Process Design using Aspen HYSYS and Feasibility Studies

Creator:: Meeuwsen, Rachel M.
Abstract:: High purity isopropyl alcohol (IPA) is utilized in silicon wafer manufacturing in cleaning and drying processes. With the ever-decreasing die size, there is an increased need for even higher purity chemicals. This process was designed to further purify a 250,000 lbs/month stream high purity isopropyl alcohol stream for use in...

Inferring Patterns and Processes of Emergence in Clonal Phytophthora Epidemics using Population Genomic Approaches

Creator:: Cauldron, Nicholas C.
Abstract:: Oomycete and fungal pathogens threaten food, fiber, and forests around the world. With climate change, these pathogens are expected to emerge more frequently. Evolution can facilitate their emergence through mechanisms such as mutations that change or expand host range. Characterizing evolutionary mechanisms in plant pathogens will contribute to our ability...

A catchment-scale assessment of stream temperature response to contemporary forest harvesting in the Oregon Coast Range

Creator:: Kevin Bladon, Nicholas Cook, Jeffery Light, and Catalina Segura
Abstract:: Historical forest harvesting practices were reviewed in the original Alsea Watershed Study where they found increased energy loading to the stream and produced higher stream temperatures. This was an important early research site that led to the development of contemporary forest management practices to protect water quality and fish habitat...

Solvent and Dispersion Effects on the Hydrodeoxygenation of Acetic Acid on a Pd(111) Model Surface

Creator:: Rebarchik, Michael A.
Abstract:: Increased dependence on fossil fuels and concerns of anthropogenic climate change have led to increased interest in alternative energy sources. Liquid fuels derived from renewable raw materials have gained attention in recent years due to their similarity to petroleum-based fuels. Biofuels derived through hydrodeoxygenation have been found to be one...

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...

Prionitis and herbivore interactions of Oregon’s rocky intertidal tidepools

Creator:: Patrick, Nicholas J. Jr.
Abstract:: The study related the density of herbivores to the length and density of Prionitis spp. in Oregon’s coastal tidepools. Oregon’s coastal rocky intertidal tidepools contain a variety of species interactions, including algal grazing by herbivores. The red branched algae Prionitis spp. is found throughout the rocky intertidal in the low...

Wave Energy Converter Archetypes and Power Performance Representation

Creator:: May-Varas, Nicholas and Robertson, Bryson
Abstract:: There is a continuing and increasing need to develop renewable energy technologies that are efficient, cost-effective and produce usable forms of energy. Wave energy converters (WECs) have an opportunity to play a key and significant role in the integration of renewable energy technologies on a commercial scale. It is estimated...

Coastal protection and conservation on sandy beaches and dunes : Context-dependent tradeoffs in ecosystem service supply

Creator:: Ruggiero, Peter, Seabloom, Eric W., Hacker, Sally D., Biel, Reuben G., and Cohn, Nicholas
Abstract:: Managing multiple ecosystem services (ESs) across landscapes presents a central challenge for ecosystem-based management, because services often exhibit spatiotemporal variation and weak associations with co-occurring ESs. Further focus on the mechanistic relationships among ESs and their underlying biophysical processes provides greater insight into the causes of variation and covariation among...

Using SIMD and SIMT vectorization to evaluate sparse chemical kinetic Jacobian matrices and thermochemical source terms

Creator:: Curtis, Nicholas J., Niemeyer, Kyle E., and Sung, Chih-Jen
Abstract:: Accurately predicting key combustion phenomena in reactive-flow simulations, e.g., lean blow-out, extinction/ignition limits and pollutant formation, necessitates the use of detailed chemical kinetics. The large size and high levels of numerical stiffness typically present in chemical kinetic models relevant to transportation/power-generation applications make the efficient evaluation/factorization of the chemical kinetic...

Experiments with Seasonal Forecasts of ocean conditions for the Northern region of the California Current upwelling system

Creator:: Siedlecki, Samantha A., Kaplan, Isaac C., Hermann, Albert J., Nguyen, Thanh Tam, Bond, Nicholas A., Newton, Jan A., Williams, Gregory D., Peterson, William T., Alin, Simone R., and Feely, Richard A.
Abstract:: Resource managers at the state, federal, and tribal levels make decisions on a weekly to quarterly basis, and fishers operate on a similar timeframe. To determine the potential of a support tool for these efforts, a seasonal forecast system is experimented with here. JISAO’s Seasonal Coastal Ocean Prediction of the...
