Bartels-Rausch, Thorsten - Paul Scherrer Institut - Laboratory of Environmental Chemistry

个人简介

I studied chemistry in Würzburg (Germany), Trondheim (Norway) and at the Swiss Federal Institute of Technology in Zürich (ETH) where I received my master degree in 1999. Master thesis at the Swiss Federal Institute for Aquatic Science and Technology (Eawag) with a work on the trace analysis of organic pesticides in water samples. PhD at the University of Berne (2003) under the supervision of Heinz Gäggeler and Markus Ammann (Paul Scherrer Institute): Uptake of atmospheric trace gases on ice and snow surfaces. Thermodynamic description of adsorption processes. Work on the effect of snow properties on adsorption processes. Post-Doc at the University of Toronto (Canada) with work in the laboratory of Jamie Donaldson and of Jon Abbatt. Investigation of the photolysis of nitrogen oxides on snow surfaces. Development of an experimental method to better characterise the ice surface and understand its role during uptake processes. Since 2006 scientist in surface chemistry group at the Paul Scherrer Institute.

研究领域

Snow and ice are chemically active. The resulting fluxes of nitrogen oxides and volatile organics impact air quality and climate change. Snow can also trap trace gases, such as toxic mercury, from the atmosphere. During snow melt these contaminants are released to the aquatic environment where they can enter the food web. Those large-scale effects within the Earth system have been partially assigned to chemical processes in ice and snow. (Bartels-Rausch et al., Atmospheric Chemistry and Physics 14, 1587-1633, 2014) To better understand these processes on a fundamental level, we do laboratory based experiments: investigate the interaction of trace gases with ice on a molecular level taking full advantage of core-level spectroscopy at the Swiss Light Source of PSI (SLS). investigate the physical interactions and chemical reactivity of trace impurities in snow and ice in larger-scale experimental systems that perfectly mimic environmental settings. This work is realized in ongoing co-operations with Martin Schneebeli (WSL-SLF) and more recently with Anja Eichler (PSI).
