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...

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...

New Graphite Intercalation Chemistry with Ethers and Amines

Creator:: Zhang, Hanyang
Abstract:: Novel donor-typed ternary graphite intercalation compounds (GICs) are synthesized and characterized containing (1) pyrrolidinium cations with DMSO co-intercalates; (2) alkali metal cations with crown ether co-intercalates; and (3) alkali metal cations with polyethylene glycol co-intercalates. Structural and compositional data are obtained for the stable products. A new ether-amine co-intercalate exchange...

Structure-property relationships of YbFe₂O₄-type layered transition metal oxides

Creator:: Grajczyk, Rosa
Abstract:: The structure–property relationships of solid solutions within the YbFe₂O₄ family of compounds have been studied in relation to their optical, dielectric and magnetic properties. This family of compounds is of recent interest because of the trigonal bipyramid coordination that is rarely observed in transition metal oxides. The systematic study of...

In-Situ Confocal Scanning Laser Microscopy and Post-Exposure Analysis of a Cu/Fe-based Oxygen Carrier Material in High-Temperature Oxidation and Reduction Environments for Chemical Looping Combustion Applications

Creator:: Nealley, W. H. Harrison
Abstract:: A Cu/Fe-spinel-based oxygen carrier designed at the National Energy Technology Laboratory was studied in order to characterize its physical and chemical behavior with cyclic oxidation and reduction treatments at 800°C for applications in chemical looping combustions. Observations were made on individual particles of the oxygen carrier in-situ using a confocal...

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...

Development of traceable metal oxide nanoparticles for examining environmental fate and transport

Creator:: Rowbotham, Brian
Abstract:: The fate and transport of engineered nanoparticles (ENPs) such as titanium dioxide (TiO₂) are of concern due to their increasing use in consumer products. Although analytical methods for detection and quantification of ENPs in environmental matrices are being developed, these methods are difficult, time consuming, and not easily validated for...

Characterization of Bonding Defects in Carbon Fiber-Epoxy Plates via Thermal Wave Imaging

Creator:: Jolibois, Michael
Abstract:: Thermal wave imaging (TWI), a technology based on heat conduction and radiation through materials, is a relatively new addition to current non-destructive inspections (NDI) systems. Bonding of composites, an extremely important step in manufacturing and repair of laminates, could be affected by defects originating from faulty manufacturing processes or damages...

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...

Tuning Functional Properties of Pyrochlore and Related Oxides via Cation and Anion Substitutions

Creator:: Giampaoli, Gabriella C. S.
Abstract:: Inorganic structures play an important role in materials due to their versatility and diversity. A complete understanding of the structure of a material is vital to enhance the creation of new materials that fill voids in research. The rational design of these compounds is driven by the exploitation of structure-property...
