Barrett, The Honors College Thesis/Creative Project Collection
Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.
Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.

Ozone is a highly reactive compound that is harmful at very low concentrations as compared to other pollutants. One method of pollution control is the use of photocatalysis, specifically with titanium dioxide to induce ozone decomposition. An experiment was designed and executed in order to determine the rate of decomposition by coating concrete in 5% by weight titanium dioxide mixed with paint. The experiment was unsuccessful in inducing decomposition but gave important insight into the adsorptive properties of ozone over surfaces, particularly with bare concrete that had an adsorption of 22.51 ± 2.457 ppbv, which was much better than the coated samples. Further studies into the development of photocatalytic paint is needed in order to develop an effective urban ozone pollution control method to be implemented in major cities, particularly in the most polluted such as Los Angeles, California.
In this study, the adsorption of a certain mold volatile organic compound onto interior surfaces was investigated. The model volatile organic compound examined was ethanol vapor, and the interior surface used was gypsum wallboard. Classical rate law kinetics were used to define this reaction.
This project aims to develop a new technology and technique that will aid in the relatively automated detection of respiratory-related changes that are exacerbated by air pollutants (e.g. lung function/respiratory changes due to air-pollution-induced asthma). This work involves understanding air transport in the human respiratory system (including the chemical and physiological impacts of air pollutants), advancing the state of the art in sensing, acoustic signal processing, and machine learning to enhance automation.
