Rachel successfully defended her thesis today entitled "Radical Cloud Chemistry: Oxidation of organic compounds in atmospheric water". Congratulations Dr. Hems on your incredible work in the past five years!
We also wish to thank Rachel for her contributions to the group as the group social coordinator and her efforts in strengthening the entire chemistry community at University of Toronto.
Rachel will continue her journey in atmospheric chemistry as a postdoctoral fellow at University of Michigan, starting in February 2020. We wish her all the best for all future endeavours!
For the first time, the Abbatt group went to the SETAC Meeting! Chen, Chris and Rachel, along with chemists from six other research groups in Environmental Chemistry at University of Toronto, attended the SETAC North America 40th Annual Meeting held from November 3-7, 2019 at Metro Toronto Convention Centre. They all presented their research in the session of Chemistry and Exposure in the Indoor Environment, covering the topics of indoor cigarette smoke and indoor cleaning.
Aaron, Chris, Tengyu and Zilin attended the 37th AAAR (American Association for Aerosol Research) Annual Conference held from October 14-18, 2019 in Portland, OR. Aaron, Chris and Zilin all presented their research on heterogeneous ozone oxidative chemistry indoors, with their special focus on THC, tobacco smoke and lipids respectively. Tengyu presented his work on SO2 oxidation in atmospheric partices. Prof. Abbatt also gave a talk on the recent progress on the HOMEChem campaign in 2018, which was mostly done by Chen.
Chen and Zilin attended the American Chemical Society (ACS) Fall 2019 National Meeting & Exposition in San Diego, CA, from August 25-29, 2019. They both presented their recent work on indoor chemistry. Prof. Abbatt also attended the meeting and gave a talk on chemical aging of brown carbon aerosol material done by Rachel.
Congratulations to Chris and Rachel, who are selected as the participants at the 15th Atmospheric Chemistry Colloquium for Emerging Senior Scientists (ACCESS XV)! They spent a weekend at Brookhaven National Laboratory on Long Island, NY from July 25-28, 2019, and later joined with Chen, Elijah and Abbatt group alumni at the Gordon Research Conference (GRC) in Atmospheric Chemistry, held at Sunday River in Newry, Maine from July 28 to August 2, 2019.
Ellen attended the 27th International Union of Geodesy and Geophysics General (IUGG) Assembly held in Montréal, from July 8 to 18, 2019. She presented her research work on pollen from North American trees: ice nucleation ability and its response to atmospheric oxidation.
Tengyu attended the 11th Asian Aerosol Conference (AAC) 2019 at the City University of Hong Kong (CityU) in Kowloon, Hong Kong from May 27-30, 2019. He presented his research on the kinetics of SO2 oxidation in sub-micron, deliquesced aerosol particles. Prof. Abbatt was also one of the plenary speakers and gave a talk on group's most recent indoor projects.
Prof. Abbatt is the recipient of the Chair’s Distinguished Teaching Award in the Department of Chemistry this year. This award is in recognition of his contributions to both undergraduate and graduate teaching in the environmental chemistry program. Jon has made contributions to numerous courses over the last few years, including 1st Year seminar courses on Energy and the Environment, CHM210 Chemistry of Environmental Change, CHM310 Environmental Chemistry, and upper level and graduate courses in Atmospheric Chemistry and the Transport and Fate of Chemical Species. (Message from Rob Batey, Chair)
Steph attended the SOLAS (Surface Ocean Lower Atmosphere Study) Open Science Conference in Sapporo, Japan from April 21-25, 2019. She presented her recent PhD research on secondary organic aerosol production from the oxidation of Thalassiosira pseudonana cultures.
Chen, Rachel and Megan (now at Lawrence Berkeley National Laboratory) attended the 14th iCACGP Quadrennial Symposium and the 15th IGAC Science Conference in Takamatsu, Kagawa, Japan from September 25 to 29. Chen presented her work on reaction of limonene with HOCl/Cl2 in indoor environments. Rachel presented her research on the atmospheric aging of biomass burning brown carbon.
Rachel also participated in the 2018 iCACGP/IGAC Early Career Short Course in Shodoshima, Japan. Click here to read more about her trip in Japan. (U of T Chemistry News)
Chen, Zilin and Doug attended the 2018 Chemistry of Indoor Environment Science meeting sponsored by the Alfred P. Sloan Foundation. The meeting took place at the University of Colorado Boulder on October 24-26. Chen presented her work on measurement of indoor organic acids and HONO during HOMEChem field campaign. Zilin presented his work on indoor multiphase ozonolysis. Doug (now at Bucknell University) discussed his research on indoor surface chemistry mostly done during his postdoctoral fellow at the Abbatt group. Prof. Jon Abbatt also gave a pre-meeting tutorial on surface chemistry with recent research progress at the Group.
Elijah and Zilin attended the 10th International Aerosol Conference (IAC 2018) held in St. Louis, MO from September 2-7. Elijah presented his research on photochemical aging of light-absorbing biomass burning aerosol and Zilin presented his work on the condensed-phase ozonolysis of an unsaturated triglyceride. During the conference, the Abbatt group had a reunion with alumni around the world. Hope to see you all again in the next conference!
Chen recently participated in the HOMEChem field campaign (House Observations of Microbial and Environmental Chemistry) in the test house at University of Texas, Austin. This field campaign, funded by the Alfred P. Sloan Foundation, involves over 20 research groups from 13 universities to study chemistry in indoor environments. Chen was operating our Time-of-flight Chemical Ionization Mass Spectrometry, measuring gas phase organic acids, HONO, and HNCO during the campaign.
In July, Chen also attended the Indoor Air conference in Philadelphia and gave an oral presentation entitled “Nucleation of ultrafine particles arising from oxidation of cigarette smoke in indoor environments”.
Her first stop was Hyytiälä Forestry Field Station in Southern Finland, where she set up the particle concentrator for an international field research campaign on ice formation in the atmosphere.
At her 2nd stop, Ellen attended the INUIT Final Conference/ 2nd Atmospheric Ice Nucleation Conference from February 26 – March 1 in Grasellenbach (Germany) – the final conference of the INUIT project. She presented results from the first evaluation of the Portable Ambient Particle Concentrator (PAPC) during the CLACE/INUIT field campaign at the High Altitude Research Station Jungfraujoch in winter 2017.
Her last and longest stop was a 1-month visit for all of March in the Lab and field group led by Dr. Zamin Kanji, part of the Lohmann group at ETH Zurich, to use their new drop freezing setup to study pollen as ice nucleating particles for warm temperatures between 0 and -30 °C.
Ellen also attended the 52nd CMOS Congress in Halifax during June 11 – 14 and presented preliminary results from her research stay at ETH Zurich earlier in the year.
Steph and Rachel attended the annual CIMS Users Meeting 2018 at the University of Washington in Seattle from June 6 - 9. They joined the researchers around the globe for discussions on chemical ionization mass spectrometry.
