Congratulations to McNeill Group Alumni New NSF Fellows!

Our heartiest congratulations to Mark De Luna (L) and Andrew Sumner (R), new recipients of the NSF Graduate Research Fellowship! Mark is pursuing his Ph.D. in Chemical Engineering at USC, and Andrew is in the Ph.D. program in Chemical and Environmental Engineering  at Yale.  They join a growing list of former McNeill Group undergrads who have gone on to win this award.  Congratulations guys!

New paper featuring the use of simpleGAMMA to model SOAS 2013 data

We’re very pleased to announce the publication of this paper, led by the Surratt Group at UNC.  It is the first example of the application of simpleGAMMA to model and help interpret field measurements of tracer species for aqueous SOA formation.

McNeill Group: Feature article and cover of ES&T!

Prof. McNeill was invited to write a Feature article on aqueous atmospheric chemistry for ES&T, which was published in this week’s issue.  She also got to design the cover art to go with the theme of the Feature article!

Got aqueous aerosol SOA formation in your model? simpleGAMMA in GMDD

We are happy to announce that our paper on simpleGAMMA is now available online!  We welcome your comments.

simpleGAMMA is currently being used to analyze data from SOAS 2013, and we are working with collaborators to couple simpleGAMMA with regional and global scale 3D atmospheric chemistry models – please contact Prof. McNeill (vfm2103@columbia.edu) if you are interested in using simpleGAMMA or learning more about it.

McNeill Group research highlighted in open access collection on “Chemistry in Climate Change” by the Royal Society of Chemistry

Our publication, “Organic matrix effects on the formation of light-absorbing compounds from α-dicarbonyls in aqueous salt solution (Drozd and McNeill, ES:PI 2014) has been included in a special collection of research papers, review articles, and themed collections on the subject “Chemistry in Climate Change” by the Royal Society of Chemistry.  Our paper and all the others in this excellent collection can be read and downloaded for free from the RSC until December 20th, 2014.

Here are a few other articles from the collection that we recommend:

New Publication with Collaborators at Stockholm University and University of Helsinki!

We are very happy to announce a new publication from our collaboration with Prof. Ilona Riipinen of Stockholm University!  Silja Hakkinen, a Ph.D. student at University of Helsinki who is supervised by Prof. Riipinen, visited our laboratory from Summer 2012- Summer 2014 as a Fulbright Scholar.  This paper is result of some of the fantastic work she did during that time.   Great work, Silja!

McNeill Group @ AAAR 2014!

It’s our favorite week of the year, the Annual Meeting of the American Association for Aerosol Research (AAAR)! Catch the following presentations of McNeill group work at the meeting in Orlando, FL:

 

Isoprene oxidation products got your aerosol surface tension down?

The final version of our manuscript, Climate-relevant physical properties of molecular constituents relevant for isoprene-derived secondary organic aerosol material, was published today in Atmospheric Chemistry and Physics!  This work was a result of a collaboration between the McNeill Group and the Geiger and Thomson groups at Northwestern University (the Geiger group led the project) .  This work shows that oxidation products of isoprene, a volatile organic compound emitted in large quantities by plants all over the world, can form films on the surfaces of aerosol particles and depress their surface tension.  This effect can lead to enhanced cloud formation and suppressed aerosol heterogeneous chemistry.
