Developing And Testing Redox Active Organic Molecules For Nonaqueous Redox Flow Battery Applications, Nuwan Harsha Attanayake
Developing And Testing Redox Active Organic Molecules For Nonaqueous Redox Flow Battery Applications, Nuwan Harsha Attanayake
Theses and Dissertations--Chemistry
Non-emissive, sustainable energy sources such as solar, wind, and geothermal power have continued to provide an increasing amount of electricity to support electrical grids. Due to the intermittent nature of renewable energy sources like wind and solar, grid energy storage systems must adjust for variations in and mismatches between electricity production and consumption. Among the available energy storage technologies, redox flow batteries (RFBs) are expected to play a critical role in the grid energy storage due to their decoupled energy and power, long service life, and simple manufacturing. However, the worldwide market penetration of RFB systems is still limited due …

Theses and Dissertations--Chemistry
In screening active materials for redox flow batteries (RFBs) – in which solubility is important to raise the volumetric energy density – scientists are slave to trial and error, modifying organic molecules in an attempt to optimize (increase) solubility without compromising other important properties such as stability and redox potential. A trained chemist can often predict the trends of solubility with the structural modifications in the neutral state of the materials, but when it’s come to the charged state of the materials, it doesn’t follow the same trend as the neutral species and relative values are hard to predict. The …

Synthesis Of A Soluble Thiopheneanthrone Organic Semiconductor: Thiopheneanthrone-1-Thioglycoliccarboxylic Acid, Denise M. Page
Senior Honors Theses
Organic semiconductors are currently being researched for various uses, both electronic and biologic. They are less expensive than current inorganic semiconductors and do not require doping. They are useful in many areas including thin film transistors, photovoltaic cells, and Light Emitting Diodes (LED). However, synthesizing soluble organic semiconductors has been difficult. As a result, this study undertakes the synthesis of a specific organic semiconductor aiming at increased solubility following an adapted literature protocol. Tests for solubility, fluorescence, and conductivity potential will be used to assess the potential of this molecule as a semiconductor. Synthesis of anthraquinone-1,8-bisthioglycoliccarboxylic acid as an intermediate …

USF Tampa Graduate Theses and Dissertations
Infectious diseases are the second leading cause of deaths in the world with malaria being responsible for approximately the same amount of deaths as cancer in 2012. Despite the success in malaria prevention and control measures decreasing the disease mortality rate by 45% since 2000, the development of single-dose therapeutics with radical cure potential is required to completely eradicate this deadly disease. Targeting multiple stages of the malaria parasite is becoming a primary requirement for new candidates in antimalarial drug discovery and development. Recently, 4(1H)-pyridone, 4(1H)-quinolone, 1,2,3,4-tetrahydroacridone, and phenoxyethoxy-4(1H)-quinolone chemotypes have been shown to be antimalarials with blood stage activity, …

Organic Thin-Film Transistors And Tips-Pentacene, Zachary Stewart
Lewis Honors College Capstone Collection
TIPS-Pentacene, an organic semiconductor characterized by its good electronic properties, solubility, and stability, is used primarily in organic thin-film transistors (OTFT). This research seeks to create an OTFT by crafting a stencil, depositing the source and drain onto a substrate’s surface, and processing TIPS-Pentacene onto the channel between them. In addition, if time permits, the electronic properties of several OTFTs will be compared to determine how to optimize their production.
