  • Multi-Technique Characterizations of Natural and Biomimetic Adhesives

    Creator:
    Fowler, James E.
    Abstract:
    There have been many attempts to characterize and mimic natural fluid-based adhesive systems. However, very few of these studies have examined surface or interfacial interactions between adhesive and substrate. Furthermore, until now no study has used a combination of surface analytical and kinematic techniques to determine the precise chemical mechanisms...

  • Processing of nanoscale materials

    Creator:
    Hostetler, Eric B.
    Abstract:
    The motivation for undertaking this research was to increase the understanding of processing colloidal semiconductor nanocrystals and thin films metallic glasses to enable their wider application in future devices. This research covered two unique materials, lead selenide (PbSe) nanocrystals and thin film metallic glass alloy of zirconium copper aluminum nickel...

  • 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...

  • Novel Approaches to Porous Material Discovery

    Creator:
    Sturluson, Arni
    Abstract:
    Uses for materials with a large surface area and high porosity have grown sig-nificantly in recent years. Porous materials have found usage in applications such as separation, gas storage, sensing, purification and more, prompting researchers to find and discover numerous new porous materials to suit a specific purpose. Hundreds of...

  • Functional materials for advanced energy and electronic devices

    Creator:
    Flynn, Brendan T.
    Abstract:
    Advances in energy technologies and electronics have typically occurred through either heightened performance or cost reduction. This dissertation explores both routes through a series of fundamental material studies that may contribute to the enabling of next generation devices. Solution based syntheses and deposition of chemical products offer a low cost...

  • 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...

  • Continuous Flow Microwave-Assisted Synthesis as a Potentially Scalable Nanomanufacturing Approach

    Creator:
    Albuquerque, Gustavo Henrique T. C. de
    Abstract:
    The development of nanomaterials and the potential enhancement of their chemical, mechanical, electrical, and optical properties have led to the investigation of methods for their synthesis at lower cost with enhanced performance for next generation devices. Along with the pursuit of new materials that exhibit properties of interest, industry requires...

  • Binding of bacterial lipopolysaccharide by the cationic amphiphilic peptide WLBU2 at interfaces

    Creator:
    Ryder, Matthew P.
    Abstract:
    Passage of blood through a sorbent device for removal of bacteria and endotoxin by specific binding with immobilized, membrane-active, bactericidal peptides holds promise for treating severe blood infections. Peptide insertion in the target membrane and stable binding is desirable, while membrane disruption and release of degradation products to the circulating...

  • Investigation of oxide semiconductor based thin films : deposition, characterization, functionalization, and electronic applications

    Creator:
    Rajachidambaram, Meena Suhanya
    Abstract:
    Nanostructured ZnO films were obtained via thermal oxidation of thin films formed with metallic Zn-nanoparticle dispersions. Commercial zinc nanoparticles used for this work were characterized by microscopic and thermal analysis methods to analyze the Zn-ZnO core shell structure, surface morphology and oxidation characteristics. These dispersions were spin-coated on SiO₂/Si substrates...

  • Predicting the Effect of Local Conditions on Metal-oxides: Pt/γ-Al₂O₃ Interface and Degradation of α-Cr₂O₃ Passive Film

    Creator:
    Oware Sarfo, Kofi
    Abstract:
    Metal-oxides are very important in industrial applications such as thermal barrier coatings, corrosion protection, and heterogeneous catalysis. The wide variety of applications for metal-oxides are derived from the array of properties of metal-oxides. It is, therefore, important to understand and predict the conditions of synthesis and operation to optimize the...
