  • Feasibility study for the use of a fuel cell to process landfill gas at Coffin Butte Landfill : hydrogen sulfide (H2S) detection and removal

    Creator:
    Tuinstra, Hannah May
    Abstract:
    Pacific Northwest Generating Cooperative (PNGC) operates the Landfill Gas to Energy Facility at Coffin Butte Landfill in Corvallis, OR. At this facility, three internal combustion engines use the landfill gas (predominantly methane and carbon dioxide) as fuel to turn generators that produce enough electricity to power 1,800 average sized homes....

  • Photoactuated Droplet Microfluidics

    Creator:
    Frederick, Ryan T.
    Abstract:
    A system of Photoactuated Droplet Microfluidics (PDM), in which a droplet of fluid is moved by way of the manipulation of the wettability of a spiropyran functionalized surface via irradiation with ultraviolet and visible light, was proposed. The photochromic behaviors of several species of spiropyran were studied and a procedure...

  • Interface Analysis of Titanium Dioxide and Graphene

    Creator:
    Frazier, Devon Paige
    Abstract:
    Titanium dioxide, in the anatase form, is a photocatalyst and has applications in water pollution reduction. Efficiency can be improved with a graphene substrate, which delays electron-hole recombination and may reduce the band gap. In this work, we determine if graphene can also act as a morphactant, changing the shape...

  • Frequency-Dependent Rheological Characterization of Viscoelastic Materials Using Magnetic Nanoparticle Probes

    Creator:
    Myers, Renee C.
    Abstract:
    Extending rheological characterization methods to very small length scales is of interest. AC susceptometry using magnetic nanoparticle probes has been proposed for measurement of frequency-dependent rheological properties at the nanoscale. As this technique has been primarily used for ideally Newtonian fluids, this research aimed to extend this technique to viscoelastic...

  • Lead(II) Extraction with Electrospun Spiropyran Functionalized PMMA Nanofibers

    Creator:
    Fuchs, Brian K.
    Abstract:
    A system to reversibly extract Pb²⁺ ions from aqueous solutions using spiropyran functionalized nanofibers was proposed. Spiropyrans are photochromic compounds which undergo a conformational change that alters their physical properties and makes Pb²⁺ binding possible upon irradiation with UV light (365 nm). Irradiation with green light (525 nm) reverses this...
