Talk:  Characterization of Aqueous Secondary Organic Aerosol from Dicarbonyls

     Dr. Christen Strollo, College of St. Benedict & St. John’s University
Christen graduated from Muhlenberg College in 2006 before attending the University of California, Riverside where she received a Ph.D. in chemistry in 2013 under the direction of Paul Ziemann.  Christen spent a year as a Visiting Assistant Professor at Lyon College in Arkansas before starting a tenure track position at the College of Saint Benedict and Saint John’s University in central Minnesota.  She teaches a variety of intro and upper division courses that combine her interests in analytical, physical and environmental chemistry in addition to courses in the environmental studies department and integrative science department.   Her research focuses on the atmospheric reactions of small molecules and their ability to form particles.  When she’s not training future scientists, Christen enjoys spending time outdoors

Glyoxal and methylglyoxal are two common dicarbonyls found in the earth’s atmosphere, originating from the oxidation of both biogenic and anthropogenic sources such as isoprene and toluene. They are oxidized in the atmosphere by hydroxyl radicals and can also partition into the aqueous phase, where they can undergo further oxidation or accretion reactions. These small molecule reactions are thought to play a role in the formation of secondary organic aerosol (SOA), which contribute to the overall amount of particulate matter in earth’s atmosphere. Aerosols affect air quality, cloud formation, and global temperature, as they reflect or absorb light, depending on their composition.  There is a discrepancy in the predicted and measured concentration of SOA due to an uncertainty in its formation mechanism.  Data will be presented from kinetic studies of the aqueous oxidation of glyoxal and methylglyoxal, as well as the identification of products formed during such reactions. Preliminary data shows evidence of a zero-order reaction (k = 3 x 10-7 M s-1) for glyoxal, and a first order reaction (k = 2 x 10-4 s-1) for methylglyoxal.  The ability of organic aerosol to serve as cloud condensation nuclei (CCN) is probed by measuring the deliquescence relative humidity (DRH) of inorganic salts, organics, and mixtures of compounds that could be present in aerosols. We implement a method of determining deliquescence and efflorescence using a quartz crystal microbalance (QCM) equipped with a humidity chamber.  Preliminary studies show that mixtures of organics and inorganics produce a decreased and less defined DRH compared to the pure salts.

    In the world of competitive and professional sports, chemistry is more impactful than you might think. Discover the materials that chemists are creating to enable athletes to perform better and stay safer, as well as how analytical chemistry is advancing to detect performance enhancing substances in order to keep the playing field level for everyone. During this interactive event, viewers will be able to network with young chemists and have an opportunity to ask questions live to the experts regarding the amazing work that is being done in sports science.

What You Will Learn:

•    How Shear Thickening Fluids can be used for impact protection and concussion mitigation
•    Textile Innovation within the sports performance categories
•    How fiber formulation and materials innovation will make or break a brand
•    How analytical science can help deter drug misuse
•    How mass spectrometry provides the optimum tool for the job
•    Why analytical chemists should remain vigilant and use state-of-art analytical tools to detect newly-emerged doping agents.
