  • Fabrication of a flexible glucose sensing catheter for human implantation

    Creator:
    Matthews, David J.
    Abstract:
    Flexible electronics processing techniques were applied to integrate a glucose sensor with a hormone-delivery catheter in order to create a cheap and minimally invasive method for patients with type 1 diabetes to continually monitor and control their blood sugar levels. Ultimately, this work intends to move toward the development of...

  • The Effect of Surface Finish on Ball Grid Array Lead Free Solder Joints

    Creator:
    Casali, Dick R.
    Abstract:
    As microelectronic parts trend smaller so do their solder joints. The surface finish on a copper pad is expected to become a significant part of the total solder joint volume and therefore affect mechanical properties of the smaller solder joints. Two sample geometries and four different surface finishes for tin-silver-copper...

  • Conversion of glucose to hydrogen gas by supercritical water in a microchannel reactor

    Creator:
    Goodwin, Aaron K.
    Abstract:
    Glucose was gasified in supercritical water within a microchannel reactor at 650°C – 750°C, and 250 bar to yield H2 rich gas with a low concentration of CO. The feed glucose concentration was 0.1 M. Two microchannel reactor configurations were tested at fluid residence times ranging from 0.5 sec to...

  • Synthesis and characterization of Pb(Zr,Ti)O₃ thin films for microelectromechanical systems

    Creator:
    Brookshire, Kirsten L.
    Abstract:
    Pb(Zr,Ti)O₃ (PZT) is a very attractive material for use in piezoelectric-based microelectromechanical systems (MEMS) due to its high piezoelectric coefficients and ability for large displacements with relatively low applied fields (as compared to electrostatic-based MEMS). The piezoelectric effect is strongly anisotropic, thus it is very desirable to control the crystallographic...

  • Crystallization and Growth of TiO2 Polymorphs from Pulsed Laser Deposited and RF-Sputtered, Amorphous Thin-Film Precursors

    Creator:
    Agirseven, Okan
    Abstract:
    TiO2 is a versatile wide bandgap transparent semiconducting oxide with three well known polymorphs: Anatase, Rutile and Brookite. These crystal structures are desired for many industrial applications mainly for their photocatalytic activity, oftentimes in thin-film form. Thin-film crystalline polymorphs of TiO2 are often made by physical vapor deposition on a...

  • 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...

  • Characterizing Accelerated Weathering Conditions for Wood Adhesive Bonds

    Creator:
    Sutfin, Micah L.
    Abstract:
    Accelerated weathering (AW) tests have become a requirement for many wood composite products. This project monitored temperature and moisture content of specimens undergoing AW exposure for the following standards: ASTM D3434 (automatic boil test), CSA O112.9 (boil-dry-freeze), and PS2 (Section 7.17, 6-cycle VPS). Each AW procedure was conducted with three...

  • The Use of Various Morphologies of Nanocellulose as Life Long Anodes of Sodium Ion Batteries

    Creator:
    Schardt, Jenna
    Abstract:
    Sodium-ion batteries (SIBs) require the use of a highly reversible anode. To form this anode carbon nanofibers and nanocrystals are derived from cellulose nanofibers, cellulose nanocrystals, and bacterial nanocellulose. The primary structure of the cellulose nanofibers is maintained when carbonized allowing for high surface area in the structure. The carbon...

  • Substitutional Effects on the Electromechanical Properties of Lead-free, Piezoelectric (Na₀.₅Bi₀.₅)TiO₃-BaTiO₃ (NBT-BT)

    Creator:
    McQuade, Ryan R.
    Abstract:
    This work investigates the effect of cation substitution on the properties of the lead-free, solid solution (Na₀.₅Bi₀.₅)TiO₃-BaTiO₃ (NBT-BT). Substitution into NBT-BT increases disorder and increases the relaxor ferroelectric properties. These relaxor ferroelectric materials show large piezoelectric strains that can be utilized in actuator applications. Ceramic samples were prepared using standard...

    Dokken, Connor B.
    Abstract:
    The advancement of new manufacturing techniques such as additive manufacturing enable significantly greater freedom of design compared to conventional techniques. Of significant interest is what improvements could be made in the design of cold plates and heat sinks for electronics cooling. Greater design freedom could potentially enable new designs that...
