Alyson successfully defended her thesis entitled “Illuminating Urban Grime: The Atmospheric Impact of Urban Grime Photochemistry”. Congratulations Alyson!
Mark presented his summer research under the title of "Predicting the Evaporation Rate and Deliquescence Using Accoustic Levitation." His research worked off of Nicole's earlier work as he focused on looking at the effects of high versus low relative humidity on the evaportation rate and deliquescence of different solutions. Well done Mark!
We say goodbye to Karen today as she leaves the group after graduating. It has been an honor and a privelege! We wish her all the best.
Alyson and Nicole both won Student Oral Competition awards at the CSC in Halifax! Alyson presented an overview of her urban grime studies in Toronto and Leipzig, and Nicole presented her MSc. research on the effect of solutes on the evaporation of water.
Alyson's recent paper, Formation of reactive nitrogen oxides from urban grime photochemistry, has been published in Atmospheric Chemistry and Physics: Atmos. Chem. Phys., 16, 6355-6363.
We welcome Mark Croxall to the group to work with us during the summer. Mark will be following in Nicole's footsteps as he continues to work with droplets using the accoustic levitator.
Nicole has officially completed her MSc. thesis: "Measurements of aqueous droplet evaporation rate as a function of solute species." Congratulations, Nicole!
Karen did a great job presenting her research, "Nitrate photolysis in snow: Influence of temperature and salt concentration on gas phase products," at the CHM499 Poster Session. Congratulations, Karen!
Alyson's recent research on the formation of reactive nitrogen oxides from urban grime photochemistry is up for discussion at Atmospheric Chemistry and Physics.
Tomorrow Nicole will be presenting the results from her MSc. research, studying the effects of solutes on the evaporation of water from droplets, at the Environmental Chemistry Seminar: 2 PM in Davenport East.
Tomorrow Alyson will be crossing the Atlantic to visit Leipzig, Germany and collaborate with TROPOS scientists to model the impact of grime photochemistry in urban environments.
Angela is on a 6 month IACPES exchange at the Paul-Sherrer Institute in Villigen, Switzerland, where she will be working with Dr. Thorsten Bartels-Rausch. Enjoy the Alps!

The Donaldson Group has expanded by 2! Welcome to our new PhD student, Laura Stirchak, and undergraduate thesis student, Karen Morenz!
Jamie spoke with the press at ACS Boston to discuss Alyson's research on the photochemistry of urban grime, which suggests that grime is not a permanent sink for nitrogen oxides. Watch the press conference here!
Dr. Sarah A. Styler, Donaldson Group alumna, is a new assistant professor at the University of Alberta! Her research group will study the chemistry of atmospheric aerosols in polluted urban environments. Congratulations, Dr. Styler!
Jamie gave a talk discussing what we still don't understand about snowpack chemistry, and Nicole presented her first poster on the evaporation of water from aqueous salt droplets.
The Donaldson Group welcomed Nicole, our new MSc student, with an afternoon sail on Lake Ontario!
Angela is participating in the UWBOS 2014 study, measuring nitrogen oxides and ozone within and directly above the snow. She hopes to probe the air-ice chemical interaction of reactive nitrogen species in order to understand their role in wintertime ozone pollution in the Uintah Basin, UT.
Elyse successfully presented her MSc thesis, "The Influence of Organic Coatings on Atmospheric Processes at the Air-Water Interface." Congratulations, Elyse!
Angela was the lead author on "Enhanced surface partitioning of nitrate anion in aqueous bromide solutions," which was published recently in J. Phys. Chem. Lett. Hear Angela and Sumi talk about this work in slideshow form on the J. Phys. Chem. Lett. website.
Sarah spent the last half of September in Paris, where she investigated the interaction of dust with urban pollutants in the CESAM atmospheric chamber at the Laboratoire Inter-universitaire des Systemes Atmospheriques (LISA).
Dorea successfully defended her PhD thesis, "Effects of Aqueous Organic Coatings on the Interfacial Transport of Atmospheric Species," on September 23. Congratulations, Dorea!
Sumi and Sarah were selected to participate in the 12th Atmospheric Chemistry Colloquium for Emerging Senior Scientists (ACCESS XII), which took place in Brookhaven, New York, earlier this summer. They also attended and presented posters at the Atmospheric Chemistry Gordon Conference in Vermont.
Sumi successfully defended her PhD thesis, "Ion Exclusion, pH, and Halogen Activation at the Air-Ice Interface," on July 16. The group celebrated with pizza in Kensington Market. Congratulations, Sumi!
