Characterization of the optical and electrical properties of organic solar cell materials is of prime importance to organic solar cell design. This thesis describes the use of capacitive photocurrent measurements to study the exciton generation and...
This thesis is based on experimental work on electrochemically mediated charge transfer effects on Single-walled carbon nanotube bundles. The study of these effects are very important towards understanding the sensitivity of gases on nanostructures...
Single Walled Carbon Nanotubes (SWNTs), Double Walled Carbon nanotubes (DWNTs) and C60@SWNT (peapods) are three of well-ordered all-carbon nanostructures. Peapods are SWNTs filled with C60 fullerene peas. At high temperatues, C60 molecules coalesce...
Nanoparticles; Drug delivery devices; Gene therapy
The properties and broad applications of nano-magnetic colloids have generated much interest in recent years. Specially, Fe304 nanoparticles have attracted a great deal of attention since their magnetic properties can be used for hyperthermia...
Iron oxide, Fe2O3, is a promising material for water splitting reaction using solar
energy due to its stability and optimal bandgap of 2 eV. Even the recent efforts, however,
using Fe2O3 thin film materials reported low efficiencies due to poor...
Energy independence requires that the nation reduce its dependence on foreign oil imports. This can be achieved through electrification of transportation vehicles if proper battery technology can be developed. In addition, the renewable energy...
This thesis reports the reactivity of the trithiolato Ru complex PPN[Ru(DPPBT)3] (DPPBT = 2-diphenylphosphinobenzenethiolate) (1a) with alkenes upon oxidation. Complex 1a in acetonitrile shows two redox events at -345 mV and +455 mV in the square...
Most of the structures in submillimeter-scale engineering are created from thin films, making them essentially two-dimensional (2D). Significant work has been done to fabricate 3D structures using self-folding, a deterministic form of...
I will report the development of a semi-empirical self-consistent and environment-dependent model Hamiltonian, which is intended to treat large systems in the order of 10000 atoms. This covers a range of important physical phenomena that are too...
Electronic commerce--Corrupt practices--Prevention; Internet advertising--Corrupt practices; Internet fraud
Online search advertising is currently the greatest source of revenue for many Internet giants such as Google™, Yahoo!™, and Bing™. The increased number of specialized websites and modern profiling techniques have all contributed to an...
Parks, Suzan-Lori. In the blood; Theaters--Stage-setting and scenery
From the moment the audience enters the auditorium the play is a mystery. They are looking for clues as to the nature of the story in which they are about to participate. The designer's job is to select what these clues are. How does the designer...

"If this generation of youth is lost, much of the hope for an economically, socially and technologically strong nation will also be lost." - Kuykendall, 1992 When youths become convinced that they will not be able to make it in mainstream...
The oxidation of metallothiolates is complicated by "non-innocence" or potential
redox activity of sulfur to yield thiyl (RS•) radicals. In some instances, the one-electron
oxidation of metal thiolates yields a product with the unpaired...
Address: 1100 W. Market Street, Louisville, Kentucky. A brick road with trolley tracks runs outside the Goldstein & Moseson store. Advertising itself as "The Home of Good Clothes" the store's windows display shirts, ties, canes, and...
