Electronic Theses and Dissertations
Recently, the use of materials with nanoscale morphologies has expanded, particularly with applications in energy conversion, catalysis, and energy storage. One drawback to single crystalline nanomaterials, especially 1D nanowires, is the difficulty in synthesizing these compounds, as the material chemistry becomes more complicated. Metal oxide nanowires can be synthesized easily and can be produced in relatively large quantities. However, more complex materials, such as metal chalcogenides, cannot typically be synthesized using facile methods, and currently very few techniques involve scalable methods. Phase transformation of metal oxides nanowires to form metal sulfides and selenides by gas-solid reactions is one viable route …

Electronic Theses and Dissertations
Electrical stimulation has been increasingly used by research groups to enhance and increase maturation of cells in an engineered cardiac tissue (ECT). Current methods are based on using off-the-shelf wires or electrodes to deliver a stimulus voltage to the in-vitro tissue in culture medium. A major issue with this approach is the generation of byproducts in the medium due to the voltage levels required, which are typically in the range of 5V-10V. No solution currently exists that can accomplish electrical stimulation of cells in an ECT at a low voltage level. Therefore, in this study a novel, porous, thinfilm, microelectrode …

Electrically conductive polymers encompass an exciting field of research for applications in dye-sensitized solar cells (DSSC’s). DSSC’s possess several advantages over other types of solar cells. They offer the potential for high quantum efficiency, solar conversion efficiency approaching that of traditional silicon panels, rapid charge transfer kinetics for photo-excited electrons, mechanical flexibility, and cost efficient manufacturing processes. However, key drawbacks to their large scale production and performance lifetime lie in their reliance on costly indium tin oxide (ITO), fluorinated tin oxide (FTO), and platinum for electrode materials, and the mechanical fragility inherent to a liquid electrolyte layer component. Much of …
