Chen, Zilin and Doug Attend the 2018 Chemistry of Indoor Environments Science Meeting

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. 

The Abbatt Group and Alumni at IAC2018

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 Participated at HOMEChem for Indoor Chemistry Studies

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”.

Ellen Outbound to Europe for Ice Nucleation Research

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 Attend the CIMS User Meeting 2018

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.

The Abbatt Group at AGU2017

Elijah, Steph, Megan, and Rachel traveled to New Orleans for the AGU 2017 meeting from December 11-15. They presented their research in the following poster sessions: Transformations and Fate of Organic Gases and Particles in the Atmosphere, Laboratory Studies in Atmospheric Sciences, Tropospheric Composition in Cold Environments: Sources, Processes, and Impacts, and Reactivity and Cycling of Organic and Inorganic Compounds in the Atmospheric Multiphase System. It was Steph's, Rachel's, and Elijah's first time going to an AGU conference and they had a great week! Megan, a veteran AGU attendee, also had a great time!

Rachel attends the 254th ACS meeting in Washington, DC!

Rachel attended the 254th ACS National meeting held in Washington, DC during August 20 - 24. She presented her research in the session on Multi-Phase Environmental Chemistry of Aerosols, in the Division of Environmental Chemistry.  Her presentation shared first prize for the best graduate student presentation award! Congrats Rachel!

The Abbatt group welcomes two new students!

Steph Schneider and Zilin Zhou joined the Abbatt group as MSc  students this fall. Steph did her BSc at the University of Alberta, where she worked in the Styler Group research reactive oxygen species formed on dust. Her research in the Abbatt group will focus on using CIMS to study reactions that take place at the sea surface microlayer. Zilin did his BSc at the University of Ottawa, where he did undergraduate research at the A.E. Lalonde accelerator mass spectrometry lab. His work in the Abbatt group will focus on condensed-phase indoor ozonolysis of complex samples such as cooking oil and skin oil.

Chen, Jennifer and Megan attend ACCESS XIV

Chen, Jennifer and Megan attended the 14th ACCESS meeting held at Brookhaven National Lab on Long Island during July 27 - 31. They presented their research to the group of 25 ACCESS participants and then attended the Gordon Conference on Atmospheric Chemistry in Newry, Maine. It was a great week!

Jennifer leaves for Wooster

Jennifer has moved on from the Abbatt group to the College of Wooster in Ohio. She will start this fall as an assistant professor of chemistry, where her research will focus on the chemical composition and reactivity of rain water. Check out her group website!

ECC XVII

Rachel, Emma, Rio and Megan presented their work at the 17th annual Environmental Chemistry Colloquium on May 1 and 2. Students, post-docs and faculty in Environmental Chemistry come together at ECC to hear about all the great work being done in our department. The ECC was held at Miller Lash House this year, and despite the rain we all enjoyed ourselves!

Welcome Chen and Elijah

In April the Abbatt group welcomed two new post-docs!

 

Elijah did his PhD at the University of Alberta, where he studied atmospheric aggregates from the molecular-scale to the nano-scale in aerosol particles. His research interests in the Abbatt group focus on mechanisms of absorption in brown carbon.

 

Chen completed her PhD at UTSC with Prof. Frank Wania, where she studied the impact of salts on phase partitioning of atmospherically relevant molecules (Sets-"CHEN"-ow constants). In the Abbatt group, Chen is studying SOA formation from cigarette smoke.

Megan goes to the CATCH meeting

In April, Megan attended the first CATCH workshop in Guyancourt, France. The emerging IGAC activity called the Cryosphere and ATmospheric CHemistry or CATCH aims to bring together scientists studying the chemistry, biology and physics in cold regions. It was a great meeting!
