  • Synthesis and characterization of magnetic composite materials

    Creator:
    Kimmell, Robert
    Abstract:
    Iron epoxy composite materials were made and their relative magnetic permeability was measured. A measurement device was created to measure the relative magnetic permeability for the specific application. This device proved to be accurate and reliable. The magnetic properties of composite materials have been shown to be controllable, with a...

  • The adsorption of human recombinant factor VIII in the presence of the nonionic triblock surfactant Pluronic® F-68 at the air-water interface

    Creator:
    Alkhatib, Aveen K.
    Abstract:
    The adsorption behavior of a human recombinant Factor VIII (rFVIII) in the presence of the nonionic, poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) triblock surfactant Pluronic® F-68 was evaluated by dynamic air-water tensiometry. Surface tension kinetics were recorded for F-68 in the absence of protein at concentrations ranging from 0 to 10,000...

  • Analytical determination of copper speciation in Oregon highway runoff

    Creator:
    Sprick, Matthew S.
    Abstract:
    Low concentrations of dissolved copper have been shown to adversely affect the olfactory system of endangered salmonids, impairing their ability to avoid predators and likely increasing predation. It is believed that only the free ionic (Cu2+ free) and weakly complexed forms are bioavailable to organisms; these forms typically account for...

  • The effect of coagulation conditions on floc size distribution and morphology : implications for downstream treatment processes

    Creator:
    Maguire, Ian R.
    Abstract:
    Coagulation and flocculation are commonly used in drinking water treatment as a means of destabilizing and aggregating particles and promoting adsorption of dissolved organic carbon (DOC). In practice, jar tests are used to determine optimal conditions for the removal of turbidity and DOC. However, beyond the inferences that can be...

  • Mass transfer of urea, creatinine and vitamin B-12 in a microchannel based membrane separation unit

    Creator:
    Warner-Tuhy, Alana
    Abstract:
    Micro energy and chemical systems (MECS) are microfluidic systems where energy and chemical processes can be intensified by decreasing the characteristic length. This project focused on bulk fluid processing using MECS technology to intensify the mass transport of a dialyzer. The objective of this project was to design a model...

  • Experimental approach for the determination of lignin modification by manganese peroxidase

    Creator:
    Goby, Jeffrey D.
    Abstract:
    Degradation of lignin to simpler compounds is desirable for removing residual lignin during paper manufacture and accessing biomass carbohydrates for biofuel production, among other purposes. Lignin transformation using enzymes found in white rot fungi, some of nature's most efficient lignin-degrading organisms, offers a more environmentally benign, selective, and possibly less...

  • Effect of cosputtered catalyst on growth and alignment of carbon nanotubes by plasma enhanced chemical vapor deposition

    Creator:
    Gunderson, Eric P.
    Abstract:
    The effect of cosputtered catalyst on growth and alignment of carbon nanotubes (CNTs) grown by plasma enhanced chemical vapor deposition (PECVD) was investigated. Aligned CNTs were observed using a cosputtered catalytic metal deposited directly on boro-aluminosilicate glass. Catalytic metal alloys were sputtered directly onto the substrate using magnetron sputtering. Deposition...

  • Statistical analysis and speciation modeling of copper in Oregon highway runoff

    Creator:
    Bloomquist, Don J.
    Abstract:
    Low levels of copper have been shown to impair the olfactory system of threatened and endangered (T&E) salmon, decreasing their predator avoidance behavior and likely increasing mortality. However, only dissolved copper (dissCu) present as the cupric ion (Cu2+) and weakly complexed species are truly bioavailable. Previous studies indicate the vast...

  • Functional polymers and proteins at interfaces

    Creator:
    Schilke, Karl F.
    Abstract:
    Functional polymers and proteins at interfaces and surfaces are of fundamental importance for biomaterials, biocatalysis and microreactor applications. Candida antarctica lipase B immobilized on poly-DL-tryptophan tethers showed 30x higher specific activity in aqueous and non-aqueous media than the same enzyme adsorbed or covalently bound directly to the surface. An excess...

  • Prediction of mass transfer performance of microchannel dialyzersusing deconvolution of impulse-response experiments

    Creator:
    Anderson, Eric K.
    Abstract:
    The parallel implementation of a large number of functional units is necessary for any industrial scale microfluidic process. The concept of a 'numbering up' strategy where a single highly optimized functional unit that has a low individual production is replicated a large number of times to create a device that...
