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...

Optimizing Production of Xylindein by Chlorociboria sp. and its Potential for Use with Nanocellulose

Creator:: Van Court, R. C.
Abstract:: Fungi from the genus Chlorociboria are known for their production of the blue-green quinonic pigment xylindein. Extracted xylindein has been the subject of investigations ranging from fabric dying to use a coloring agent in paint, and shows potential as an organic semiconductor in organic photovoltaics (OPVs) and other technologies. However,...

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...

Thin Films via Chemical Solution Deposition Synthesis from the (Bi₀.₅Na₀.₅)TiO₃-(Bi₀.₅K₀.₅)TiO₃-Bi(Mg₀.₅Ti₀.₅)O₃ Ternary System

Creator:: Mendez, Jose Eduardo
Abstract:: The ternary system (Bi₀.₅Na₀.₅)TiO₃-(Bi₀.₅K₀.₅)TiO₃-Bi(Mg₀.₅Ti₀.₅)O₃ (BNT-BKT-BMgT) was explored along the [75-(x 2) ]Bi₀.₅Na₀.₅TiO₃ - [25-(x 2)]Bi₀.₅K₀.₅TiO₃ - [x]Bi(Mg₀.₅Ti₀.₅)O₃ composition line. Thin films were fabricated using chelated mixing route solutions spin cast onto platinized silicon substrates. Processing parameters such as: excess cation molar%, solution molality, and crystallization temperatures, for composition where x=0,...

Epsilon-Near-Zero Transparent Conductive Oxides and the Application in Electro-Absorption Modulators

Creator:: Zhou, Bokun
Abstract:: Transparent conductive oxides (TCOs), such as indium-tin oxide (ITO), have attracted increasing interests in integrated photonics and nanophotonics, owing to their large plasma dispersion and epsilon-near-zero (ENZ) effect. The refractive index modulation induced by free carriers in TCOs leads to a large electro-optic effect that can enable ultra-compact device footprint...

First principles studies of optical, electronic and mechanical properties of organic molecules and solids

Creator:: Barras, Faye Lyn
Abstract:: This thesis presents the results of quantum-mechanical first principles calculations of optical, electronic and mechanical properties of organic molecules and solids, which have diverse potential applications such as photovoltaics, flexible electronics, and mechanical catalysts with applications in force sensors and self-healing materials. The electronic and optoelectronic properties of organic thin...

Electronic Conduction and Ionic Diffusion in (Bi₀.₅Na₀.₅)TiO₃-(Bi₀.₅K₀.₅)TiO₃-based Thin Films, Electronic Conduction and Ionic Diffusion in (Bi0.5Na0.5)TiO3-(Bi0.5K0.5)TiO3-based Thin Films

Creator:: Walenza-Slabe, Joel
Abstract:: Solid solutions based on the perovskite ferroelectrics Bi₀.₅Na₀.₅TiO₃ (BNT) and Bi₀.₅K₀.₅TiO₃ (BKT) might someday replace current Pb-based ferroelectric and piezoelectric devices. This is one goal of the Restrictions on Hazardous Substances (RoHS) guidelines seeking to limit Pb in consumer devices. Although the Bi-based ferroelectrics are well suited to the task...

Potential Additive-Manufacturing of Ablative Thermal Protection Systems

Creator:: Hazell, Kenya K.
Abstract:: Electrodeposition is a versatile polymer deposition technique to create nano-microscale materials using an electrical field generated from a charged droplet of solution and a grounded collector. Electrospinning or electrospraying can occur during electrodeposition, leading to the creation of nanofibers or bead-like materials depending on the process parameters. Photopolymerization of the...

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...
