How The Phase and Quantity of Water Affect Atmospheric Chemistry

Webinar Presented By:  Hind Al-Abadleh, Professor at Wilfrid Laurier University

Speaker Bio:  Dr. Hind Al-Abadleh is a Full Professor in the Department of Chemistry and Biochemistry at Wilfrid Laurier University, the 2019 Fulbright Canada Research Chair in Atmospheric Chemistry, Air Quality, and Climate Change, the Chair of the Environment Division of the Chemical Institute of Canada, the inaugural Raymond March Visiting Scientist in Chemistry at Trent University, a founding member of the Special Interest Group on Atmosphere-Related Research in Canadian Universities and the Canadian Society of Chemistry (CSC) Working Group on Inclusion, Diversity and Equity (WIDE).  She is also an Executive Board Member of Nano Ontario and Nano Canada’s committee on the health and safety of nanomaterials and advanced materials.  Her research interests are in the fields of atmospheric chemistry, geochemistry, environmental remediation, and environmental impacts of nanomaterials.

Abstract:  Research in water sustainability in the era of climate change demands an innovative and integrated approach to thinking at multiple scales, all phases of matter, and at the interface of different phases of matter.  One can think of water scales to range from the macro (oceans, lakes, rivers, groundwater) to the micro and nano (rain drops, ice flakes, fog) to the molecular scale (hydrogen bonding network).  As the ‘environmental solvent’, water influences chemical reactions in the bulk gas and liquid phases, and at the surfaces of solid materials.  In this talk, results will be presented on (a) efficient new pathway for organic and organometallic polymeric particle formation from aqueous phase iron-catalyzed reactions with aromatic and aliphatic dicarboxylic acid compounds, and (b) ice nucleation efficiency of fresh versus reacted dust particles.  The significance of these results will be presented in relation to the chemical processing of iron-containing dust in the presence of organics and how it changes dust optical and hygroscopic properties.
