Development of a framework to account for uncertainty sources in modeling toxic concentrations in the Niagara River
The Niagara River is an important natural resource for drinking water and inexpensive hydroelectric power production. However, the quality of its water is less than pristine. Past lax management of toxic waste has left ...
Terahertz spectroscopy of semiconductor nanostructures
Electromagnetic waves centered at a frequency of 1 terahertz (THz) lie between the realms of photonics and electronics. Only recently have techniques been established to generate and detect electromagnetic waves in this ...
Aerosol spray pyrolysis & solution phase synthesis of nanostructures
This dissertation focuses on the synthesis of nanomaterials by both solution phase and gas phase methods. By the solution phase method, we demonstrate the synthesis of Au/CdS binary hybrid nanoparticles and the Au-induced ...
Readout of electron spins in quantum point contacts
This thesis is motivated by recent interest in the binding of single spins on quantum point contacts (QPCs). While this regime is inaccessible to experiments performed on single QPCs, this thesis provides strong evidence ...
Hybrid semiconductor nanomagnetoelectronic devices
The subject of this dissertation is the exploration of a new class of hybrid semiconductor nanomagnetoelectronic devices. In these studies, single-domain nanomagnets are used as the gate in a transistor structure, and the ...
Nanostructured photovoltaic devices for next generation solar cell
As the search for alternative sources of energy other than petroleum continues to expand, solar energy conversion has already been identified as one of the most promising technologies. In the past few years there has been ...
Enhancement of the low frequency sound absorption of porous materials by addition of a thin high flow-resistivity cover layer
The general performance of a porous material against a rigid backing shows very good absorption qualities at high frequencies, but at lower frequencies, where the thickness becomes much less than a wavelength of sound, the ...
Robust microbial fabrication of plant pharmaceuticals: Complexities and solutions
Abstract not available.
Automated multi-parametric sorting of micron-sized particles via multi-trap laser tweezers
The capabilities of laser tweezers have rapidly expanded since the first demonstration by Ashkin and co-workers in 1970 of the ability to trap particles using optical energy. Laser tweezers have been used to measure ...
Degradation of 17alpha-ethinylestradiol in wastewater treatment systems
The existence and persistence of estrogenic chemicals in aquatic environments is a problem that may affect public and ecosystem wellness. For this reason, it is of major concern, and being investigated by those in the field ...
