  • Supercritical fluid impregnation with biocides of wood using temperature reduction

    Creator:
    Kang, Sung-Mo
    Abstract:
    Supercritical fluid (SCF) impregnation is a promising preservative treatment method, however, the development of SCF processes has been slowed by a limited understanding of the process. Developing a better understanding of the effects of various process parameters on treatment results would allow for a more rational development of SCF impregnation....

  • On the study of WEC prototype advancement with consideration of real-time life extending control

    Creator:
    Stillinger, Chad J.
    Abstract:
    Renewable energy is a topic of significant interest and importance in the world today. Ocean wave energy, particularly in areas such as the Oregon Coast, has considerable potential as a renewable resource. However, to rightly evaluate the overall cost of energy for wave energy converters, survivability and maintenance issues must...

  • Enhancement and modeling of cryogenic solid-state hydrogen storage systems with a novel microchannel thermal management device

    Creator:
    Loeb, Christopher S.
    Abstract:
    Compact storage systems demonstrating increased hydrogen storage capacity are the key to advancing the growth of the hydrogen economy throughout the world and reducing the global dependence on fossil fuels for transportation. The use of highly porous adsorbent materials for reversible hydrogen storage is a promising pathway towards achieving storage...

  • Relations between Physical Fitness and School-Day Physical Activity Behavior in Children with Autism Spectrum Disorder

    Creator:
    Tyler, Kiley J.
    Abstract:
    Background. Autism spectrum disorder (ASD) is characterized by impairments in social-communicative deficits and restricted and repetitive behaviors, interests, or activities (APA, 2013). While current estimates suggest 1 in 68 children are diagnosed with ASD, more alarming statistics indicate 1 in 50 school-aged children live with the disorder (Blumberg, Bramlett, Kogan,...

  • Continuous and rapid synthesis of nanoclusters and nanocrystals using scalable microstructured reactors

    Creator:
    Jin, Hyung Dae
    Abstract:
    Recent advances in nanocrystalline materials production are expected to impact the development of next generation low-cost and/or high efficiency solar cells. For example, semiconductor nanocrystal inks are used to lower the fabrication cost of the absorber layers of the solar cells. In addition, some quantum confined nanocrystals display electron-hole pair...

  • Aqueous chemistries for oxide electronics

    Creator:
    Meyers, Stephen T.
    Abstract:
    The variegated aqueous chemistries of metal cations are applied to the design and synthesis of non-toxic solution precursors suitable for additive printing of large-area oxide electronics. Polycondensation behaviors of aqueous Al+3 and PO4 +3 are manipulated in the deposition of atomically smooth amorphous aluminum oxide phosphate (AlPO) dielectric films. AlPO...

  • Hydrological and biogeochemical dynamics of nitrate production and removal at the stream – ground water interface

    Creator:
    Zarnetske, Jay P.
    Abstract:
    The feedbacks between hydrology and biogeochemical cycling of nitrogen (N) are of critical importance to global bioavailable N budgets. Human activities are dramatically increasing the amount of bioavailable N in the biosphere, which is causing increasingly frequent and severe impacts on ecosystems and human welfare. Streams are important features in...

  • Aging and performance evaluation of marine antifouling coatings

    Creator:
    Bunn, Malachi D.
    Abstract:
    Marine biofouling is a major problem in many industries. Shipping has been afflicted with reduced vessel speed and hindered maneuverability due to organisms attaching since the dawn of sailing. To date, the primary method developed to prevent fouling is the application of biocide laden coatings with various release mechanisms. Mass...

  • Nonthermal Plasma Microreaction Engineering for Gas and Liquid Processing

    Creator:
    Pommerenck, Justin
    Abstract:
    Atmospheric pressure plasma is non-thermal at millimeter to micrometer separations. It represents an alternative low exergy initiator of many chemical reactions. In many instances heat, light or sound are not efficient providers of the necessary energy to overcome chemical activation barriers. The focus of this research is applying dc nonthermal...

  • Inductors in high-performance silicon radio frequency integrated circuits : analysis, modeling, and design considerations

    Creator:
    Lutz, Richard D., Jr
    Abstract:
    Spiral inductors are a key component of mixed-signal and analog integrated circuits (IC's). Such circuits are often fabricated using silicon-based technology, owing to the inherent low-cost and high volume production aspects. However, semiconducting substrate materials such as silicon can have adverse effects on spiral inductor performance due to the lossy...
