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 ...
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 ...
Robust microbial fabrication of plant pharmaceuticals: Complexities and solutions

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 ...
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 ...
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 ...
Recycling acetate for improving flavanones production from Escherichia coli
Acetate is a toxic by-product of glucose metabolism in Escherichia coli. In the present work, endogenous metabolic networks of E. coli were re-designed to improve the autonomous recycling of acetate into acetyl-CoA. In ...
