Fall 2017
We present a platform for research into nanomaterial-enhanced gas sensing using magnetomotive MEMS resonators. A microfabrication process fl ow is developed and carried out to create metallized silicon MEMS resonators. In tandem, a test system based around a balanced electronic bridge is...

Aquatic nanotoxicity testing: Insights at the biochemical, cellular, and whole animal levels
DownloadFall 2013
Aquatic organisms are susceptible to waterborne nanoparticles and there is only limited understanding of the mechanisms by which these emerging contaminants affect biological processes. The unique properties of nanomaterials necessitate evaluation of standard toxicity testing techniques to...

Atomic Force Microscopy Characterization of Hydrogen Terminated Silicon (100) 2x1 Reconstruction
DownloadFall 2015
Non-contact Atomic Force Microscopy (NC-AFM) is a Scanning Probe Microscopy tool offering unique non-perturbative analysis of surfaces and adsorbates at the atomic scale. AFM precisely oscillates a sharp tip above a sample. By monitoring the shift in resonance frequency of a quartz tuning fork...

Automatically Detecting Affect in Computer-based Learning Environments: A Systematic Literature Review
DownloadSpring 2023
Affect detection is increasingly viewed as an essential component of computer-based learning systems because it aims to improve learner outcomes by adapting to the learner’s affect. However, most computer-based learning environments used across formal and informal educational contexts do not...

Fall 2023
Plasmonics deals with the collective excitations of light coupled with free electrons in matter. It has widespread use in the fields of biosensing and nanoscale waveguiding due to the enhancement of the electric fields. My thesis deals with an important frontier in the field of plasmonics by...

External sensors for the feedback control of functional electrical stimulation assisted walking
DownloadFall 2010
Functional electrical stimulation (FES) is a rehabilitative technology that can be used to improve walking in individuals with mobility impairments due to neurologic injury or disease. Feedback is essential for efficient FES-assisted walking. The overall goal of my project was to investigate...

On a perfect hydrogen-terminated Si(100)-2x1 surface, each surface silicon atom is capped with exactly one atom of hydrogen. When one of the capping hydrogen atoms is removed, the now unsatisfied orbital of the underlying silicon atom is exposed at that site. This site is better known as a...

Spring 2016
This thesis explores the dynamics and sensing performance of silicon quantum dot (SiQD) ensembles coupled to the whispering gallery modes (WGMs) of spherical and cylindrical microcavities. The first project investigated the possibility of observing Purcell effects in an ensemble of QDs coupled to...

Spring 2015
This thesis focuses on the photoluminescence (PL) of free-standing silicon quan- tum dots (QDs). Large changes in the emission spectrum were found to occur when the QDs were exposed to different environments while undergoing short-wavelength laser irradiation, a phenomenon that was the main focus...

Collisions of motorized transport with wildlife impact a wide range of species and can cause injuries and economic losses to people. On roads, vehicle collisions with animals have been studied extensively, resulting in mitigation measures that reduce collisions by segregating animals and...
