Measuring the Electric Field Dependence of Photocurrent Quantum Yield in Suspended Carbon Nanotube pn Junctions

Creator:: McCulley, Daniel R.
Abstract:: In nanoscale materials, the Coulombic interaction between electrons are stronger than in bulk materials. These stronger interactions, caused by confinement and reduced dielectric screening, have interesting consequences for light-matter interactions. In carbon nanotubes (CNTs), strong interactions can enhance the impact ionization process, and thus assist photocurrent generation in CNTs. Conversely,...

Mechanisms that influence the posttranslational modification of the GluN2B subunit in the aged brain

Creator:: Zamzow, Daniel R.
Abstract:: Memory is essential to everyday life. As we age, deficits in memory become apparent. The toll of age-related cognitive impairment can be devastating to families and costly to society. The NMDA receptor is a molecule in the brain that is instrumental in the formation of memories. The receptor is particularly...

Determinants of household vehicle miles traveled in Oregon

Creator:: Holder, Daniel R.
Abstract:: This study models the household demand for vehicle miles traveled with a focus on the effects from bicycle ridership and transit ridership. Through the use of data from the Oregon Household Activity Survey collected on behalf of the Oregon Department of Transportation, evidence is found that households participating in bicycle...

Estimation of global arable and irrigable land using GIS

Creator:: Wise, Daniel R.
Abstract:: As part of a study to determine the history and potential for conflict in international freshwater basins, an estimate was made of the location of arable and irrigable land in the world. Knowledge about the world's arable and irrigable land was desired since this information could be an indicator of...

A study of high shear multiphase flow in a microchannel

Creator:: Morse, Daniel R.
Abstract:: Microscale fluid processes are an increasingly important subgroup of fluid mechanics. Applications for heat transfer and micro-electro-mechanical devices use flows on the scale of less than one hundred microns. This study is part of a larger work in which a multiphase, high shear environment is studied in a microchannel that...

Towards autonomous irrigation : comparison of two moisture sensing technologies, irrigation distribution analysis, and wireless network performance at an ornamental container nursery

Creator:: Bailey, Daniel R.
Abstract:: As ornamental container nurseries face diminishing water allocations, many are looking to automated irrigation solutions to increase their water application efficiency. This thesis presents the findings of a study conducted at a commercial container nursery to determine 1) whether a capacitance or load cell sensor was better suited for monitoring...

Nitrogen management and variety selection for dryland production of hard red winter wheat in northeastern Oregon

Creator:: Jepsen, Daniel R.
Abstract:: Proper nitrogen (N) management and variety selection are important for profitable hard red winter (HRW) wheat production in the dryland growing regions of northeastern Oregon. In these dryland systems, N management for grain yield and grain protein concentration (GPC) is challenging due to climatic and year-to-year variation in production environments....

Experiments on a low aspect ratio wing at low Reynolds numbers

Creator:: Morse, Daniel R.
Abstract:: At the start of the 21st century much of the focus of aircraft design has been turned to unmanned aerial vehicles (UAVs) which generally operate at much lower speeds in higher risk areas than manned aircraft. One subset of UAVs are Micro Air Vehicles (MAVs) which usually are no larger...

Extremely efficient photocurrent generation in carbon nanotube photodiodes enabled by a strong axial electric field

Creator:: McCulley, Daniel R., Senger, Mitchell J., Bertoni, Andrea, and Perebeinos., Vasili
Abstract:: Carbon nanotube (CNT) photodiodes have potential to convert light into electrical current with high efficiency. However, previous experiments have revealed photocurrent quantum yield (PCQY) well below 100%. In this work, we show that axial electric field increases the PCQY of CNT photodiodes. In optimal conditions our data suggest PCQY >...

Acetylene Inhibition of Azotobacter vinelandii Hydrogenase: Acetylene Binds Tightly to the Large Subunit

Creator:: Sun, Jin-Hua, Hyman, Michael R., and Arp, Daniel J.
Abstract:: Acetylene is a slow-binding inhibitor of the Ni- and Fe-containing dimeric hydrogenase isolated from Azotobacter vinelandii. Acetylene was released from hydrogenase during the recovery from inhibition. This indicates that no transformation of acetylene to another compound occurred as a result of the interaction with hydrogenase. However, the release of C2H2...
