  • Synthesis and anticoagulant function of heparin containing block copolymers on polystyrene microspheres

    Creator:
    Fry, Allyson Kaye
    Abstract:
    Contact of blood with the surfaces of synthetic materials is associated with spontaneous protein adsorption, initiating platelet aggregation, the coagulation cascade, and the eventual development of a stable clot. Current therapy to inhibit implant-induced thrombosis is life-long administration of systemic anticoagulants. An alternative to the systemic administration of anticoagulant drugs...

  • Aroma compounds in sweet dry whey

    Creator:
    Mahajan, Shilpa S.
    Abstract:
    The objective of this study was to identify aroma volatiles in sweet whey powder. Volatiles were isolated by solvent extraction and solvent assisted flavor evaporation. Fractionation was followed to separate acidic volatiles from nonacidic volatiles. Gas chromatography/olfactometry and gas chromatography-mass spectrometry were used for the identification ofaroma compounds. Osme methodology...

  • Magnetic bead detection with ferromagnetic resonance for use in immuno-biosensor application

    Creator:
    Ghionea, Simon
    Abstract:
    The objective of this thesis is to introduce and demonstrate a novel magnetic bead detector based on inductive detection at the ferromagnetic resonance (FMR) frequency for use in bio-sensing applications. Detection ability is demonstrated through theoretical arguments, numerical computer simulations, and experimental characterization of micro-fabricated detectors. The detector is composed...

  • Applications of Holographic Optical Tweezers: Multiplexed Fluorescence Spectroscopy and the Micromechanics of Type-I Collagen

    Creator:
    Cibula, Matthew A.
    Abstract:
    The development and some applications of holographic optical tweezers (HOT) are presented. Our HOT system uses a spatial light modulator (SLM) to control the location and properties of the optical trap. We have developed a method for optimizing the diffraction efficiency of a SLM that can be applied in situ...

  • Studying fusion reactions for effect of PCN on heavy nucleus formation and for nuclear structure effects

    Creator:
    Naik, Radhika
    Abstract:
    The fusion reaction ²⁰⁸Pb (⁵⁰Ti, xn) ²⁵⁸⁻x Rf (x = 1-3) was studied to determine PCN (probability that the mononucleus system evolves to form a compound nucleus inside the fission saddle point) and to establish the value of Wsur (survival probability) for the given reaction experimentally. The fission excitation function...

  • Preparation and characterization of polymer-SiO₂ hybrids

    Creator:
    Ferguson, Morgan L.
    Abstract:
    In a search for designed materials that mimic those found in biological systems, combining polymers with inorganic materials in sol-gel chemistry processes has gained momentum in the research world since the 1990's. This work methodically investigated the properties of several related polymer-SiO₂ hybrids prepared by a simple methodology that could...

  • Optimization of cryoprotectant addition and removal procedures for vitrification of adherent mammalian cells

    Creator:
    Fry Davidson, Allyson
    Abstract:
    Cryopreservation of adherent cells may be advantageous for cell types that are difficult to preserve in suspension or when it is necessary to preserve characteristics of the adherent cultured cells. Vitrification is a promising procedure for the preservation of adherent cells that prevents ice crystal formation and the resulting dissociation...

  • Hydrolytic methods for the quantification of fructose-equivalents in herbaceous biomass

    Creator:
    Nguyen, Stefanie K.
    Abstract:
    A low, but significant, fraction of the carbohydrate portion of herbaceous biomass may be composed of fructose/fructosyl-containing components (“fructose equivalents”); such carbohydrates include sucrose, fructo-oligosaccharides, and fructans. Standard methods used for the quantification of structural-carbohydrate-derived neutral monosaccharide-equivalents in biomass are not particularly well suited for the quantification of fructose equivalents...

  • Functional transition metal oxides : structure-property relationships

    Creator:
    Smith, Andrew E.
    Abstract:
    Transition metal oxides are an important class of materials for the wide variety optical, electrical, dielectric, magnetic, and thermal properties observed. Their unique structure-property relationships allow for property tuning and often provide insight into the fundamentals of chemistry. The work in this thesis was focused on the design, synthesis and...

  • The effect of hopping technology on lager beer flavor and flavor stability and the impact of polyphenols on lager beer flavor and physical stability

    Creator:
    Aron, Patricia M.
    Abstract:
    Beer is one of the most extensively consumed beverages world-wide and it is almost always brewed with hops (Humulus lupulus, L.). Hops provide beer with bitterness, aroma, flavor and texture and also enhance specific beer properties such as foam stability, clarity (colloidal stability), color, flavor stability and microbial stability. Hops...
