Non-Traditional Metallation Of Metallothioneins With Xenobiotic Therapeutic Metals, Daisy L. Wong
Non-Traditional Metallation Of Metallothioneins With Xenobiotic Therapeutic Metals, Daisy L. Wong
Electronic Thesis and Dissertation Repository
The rise of the Anthropocene has seen more global pollution than before in history. With the explosion of consumer electronics in the last half century, the rise of metal pollution from their extraction and disposal results in the unnatural introduction of heavy and rare metals into the ecosystem. Organisms have a metal defense protein, metallothionein, which has multiple roles in essential metal regulation and protection against minimal toxic metal exposure. However, these modern heavy metals prominent in electronics are not found biologically and their interactions in the body are generally unknown. Some of these metals are employed as therapeutic agents …

Chemical Kinetics Using A Smartphone Spectrometer, Mary Greggila
Williams Honors College, Honors Research Projects
In a time where many high school science classes are lacking in quality laboratory education, there is a need for accessible chemical equipment that enhance teaching fundamental concepts of chemistry with ease and at a low cost. The DualSpec handheld smartphone spectrometer aims to be a quality open-source spectroscopic instrument that can easily be made and used at home by people of any scientific level. This research sought to show that the DualSpec could be used to teach higher level spectroscopic concepts such as those used in chemical kinetics. The DualSpec was compared to a commercial spectrometer using the commonly …
On-Road Measurments Of Transit Bus Emissions, Matt Breuer
On-Road Measurments Of Transit Bus Emissions, Matt Breuer
Summer Research
Emissions were monitored from transit buses to determine the difference in emissions between engine technologies and model years. The Environmental Protection Agency’s newest emissions standards set into law in 2007 and 2010 limited the level of emissions transit buses and other heavy-duty vehicles are able to produce. For the most part, these standards have been regulated in lab. My research looked at the emissions from these buses on-road, under normal operating conditions. At the Federal Way Transit Center, four types of bus engines were analyzed: conventional diesel, diesel with catalytic emission control, compressed natural gas, and diesel-electric hybrid. A remote …
