  • The role of manganese peroxidase in biomass conversion technologies

    Creator:
    Yee, Kelsey L.
    Abstract:
    Currently, the technologies used to separate lignocellulosic biomass into its component parts (cellulose, hemicellulose, and lignin) and enzymatically hydrolyze the cellulose to glucose for conversion to ethanol could be improved economically and in terms of efficiency. A major impediment to utilizing the biomass is the presence of residual lignin. The...

    Creator:
    Devin, Jennifer N.
    Abstract:
    Assembly and genotyping of polyploid genomes poses many problems due to the complex nature of polyploid data, including the inability to determine allelic dosage and mixed inheritance patterns. This study was the first application of POLiMAPS genotyping on whole genome sequences without using cross information. In this study, whole genome...

  • Use of orthogonal collocation in the dynamic simulation of staged separation processes

    Creator:
    Matandos, Marcio
    Abstract:
    Two basic approaches to reduce computational requirements for solving distillation problems have been studied: simplifications of the model based on physical approximations and order reduction techniques based on numerical approximations. Several problems have been studied using full and reduced-order techniques along with the following distillation models: Constant Molar Overflow, Constant...

  • New application of crystalline cellulose in rubber composites

    Creator:
    Bai, Wen
    Abstract:
    Rubber without reinforcement has limited applications. The strength of reinforced rubber composites can be ten times stronger than that of unreinforced rubbers. Therefore, rubber composites are widely used in various applications ranging from automobile tires to seals, valves, and gaskets because of their excellent mechanical elastic properties. Silica and carbon...

  • Physical and numerical approximations of reactive distillation dynamics

    Creator:
    Pavarajarn, Varong
    Abstract:
    Two approaches to reduce computational requirements for solving reactive distillation problems have been studied: simplification of the model using physical assumptions and numerical approximation using an orthogonal collocation technique. The results of a full-order model with time dependent stage molar holdups was compared to published steady-state experimental data and was...

  • Oxidation Energies of Chromium and Tungsten Substituted Ni (111) Surfaces

    Creator:
    Roth, Anika
    Abstract:
    The corrosion and heat resistance properties of nickel alloys are hallmarks of their importance in infrastructure and industrial catalysis processes, but these properties are highly dependent on the chemical composition of the alloy surface. Density functional theory was used for analysis of surface oxidation of four combinations of chromium and...

  • Classifying the toxicity of pesticides to honey bees via support vector machines with random walk graph kernels

    Creator:
    Yang, Ping
    Abstract:
    Pesticides benefit agriculture by increasing crop yield, quality, and security. However, pesticides may inadvertently harm bees, which are valuable as pollinators. Thus, candidate pesticides in development pipelines must be assessed for toxicity to bees. Leveraging a data set of 382 molecules with toxicity labels from honey bee exposure experiments, we...

  • Development of solution-based reaction processes for micro- and nano-structured semiconductors

    Creator:
    Lee, Doo-Hyoung
    Abstract:
    The focus of this study is to develop a general and low-cost solution-based process to fabricate micro- and nano-structured semiconductors that are suitable for electronics. This process uses simple metal halide precursors dissolved in a solvent (organic or aqueous) and is capable of forming uniform and continuous thin films via...

    Abstract:
    This research details laboratory assessment of bacterial hydrophobicity, variations in bacterial adhesion properties with growth and extended starvation as well as extension of this assay to colloidal hydrophobicity measurement. Hydrophobicity is an integral component of surface interactions and has been studied extensively for its role in a number of engineering...
