  • Life cycle assessment of algal biofuels

    Creator:
    Kirby, Bryan L.
    Abstract:
    This thesis consists of three studies to better understand the environmental sustainability potential for algal-based biofuels. Initially, a comparison of recent life cycle assessments (LCA) of theoretical full-scale algal biofuel facilities was developed. These studies include varying boundaries and scope, functional units, and technology maturity assumptions. The comparison converted results...

  • Advection-diffusion in inertial flow through periodically converging-diverging tubes

    Creator:
    Lambert, Adam
    Abstract:
    A direct numerical simulation of advection-diffusion in a sinusoidal tube was carried out using the commercial finite-volume code STAR-CD. The Reynolds numbers varied from Re = 0.1 to Re = 14.5. At the larger Reynolds numbers, steady-state eddies formed in the diverging sections and significantly influenced the macroscale dispersion. Long...

  • Biomolecule detection by amplified photoluminescence of germanium doped diatom biosilica

    Creator:
    Gale, Debra K.
    Abstract:
    There is significant interest in the fabrication of nano- and micro-structured silica with spatially ordered features, which exhibit enhanced optoelectronic properties with application to the next generation of display devices, semiconductors, and sensors. Currents methods of fabrication employ top down processes which use extremes of temperature, pressure, and power. There...

  • Biological insertion of nanostructured germanium and titanium oxides into diatom biosilica

    Creator:
    Jeffryes, Clayton S.
    Abstract:
    There is significant interest in titanium oxide and germanium-silicon oxide nanocomposites for optoelectronic, photocatalytic, and solar cell applications. The ability of the marine diatom Pinnularia sp. to uptake soluble metal oxides from cell culture medium, and incorporate them into the micro- and nano-structure of their amorphous silica cell walls, called...

  • Numerical Methods for Upscaling Complex Transport Phenomena

    Creator:
    Taghizadeh, Ehsan
    Abstract:
    Transport phenomena specially the ones that occur in the various engineering disciplines such as tissue engineering and natural environment are often complex to analyze mostly due to the dynamic and geometric complexities; as such, they have been the subject of an active and intense area of research in past decades....

  • Models and Modeling in Capstone Physical and Virtual Laboratory Projects

    Creator:
    Nefcy, Erick J.
    Abstract:
    The research presented in this dissertation focuses on the model generation and modeling processes of student teams that participate in capstone, undergraduate engineering physical and virtual laboratory projects. The Heat Exchange Laboratory Project, the Ion Exchange Laboratory Project, and the Virtual Chemical Vapor Deposition (CVD) Laboratory Project provide the context...
