Laboratory of Environmental Chemistry

The Laboratory of Environmental Chemistry (LUC) focuses on fundamental research and education for assessing the impact of human activities and natural processes on human health, environment and climate.
The surface chemistry research group investigates multi-phase chemical processes relevant for atmospheric chemistry and the analytical chemistry research group reconstructs environmental and climatic conditions from high-altitude glaciers.

Welcome Anthony Boucly

Join me in welcoming Anthony, our new postdoc, jointly affiliated with Markus Ammann’s Surface Chemistry group (Surface Chemistry) and within the Electrochemistry Laboratory (Laboratory of Electrochemistry), the group for Electrocatalysis and Interface headed by Prof. Thomas Schmidt under the supervision of Emiliana Fabbri.

He obtained his PhD from the University of Pierre et Marie Curie in Paris, in the Laboratory of Chemical Physics – Materials and Radiation. The title of his dissertation was “Catalytical Reactions and Environmnetal Chemistry Modifications as seen by Synchrotron Radiation NAP-XPS”. He is trained in surface chemistry and surface analysis methods.

At PSI, Anthony Boucly will be studying the electrochemical interaction between electrolytes and metal oxides relevant for electrochemical applications and for the weathering of mineral dust particles in the atmosphere with X-Ray photoelectron spectroscopy at the Near Ambient Pressure Photoemission (NAPP) endstation at SLS.

Successful PhD Defense

Anna Dal Farra successfully defended her PhD at the University of Bern, entitled "Effect of light-absorbing impurities on the albedo of the Alpine glacier Plaine Morte". The project was jointly funded by the University of Bern and the Paul Scherrer Institut.

Atmosphere in X-ray light

PSI researchers have developed an experimental chamber in which they can recreate atmospheric processes and probe them with unprecedented precision, using X-ray light from the Swiss Light Source SLS. In the initial experiments, they have studied the production of bromine, which plays an essential role in the decomposition of ozone in the lower layers of the atmosphere. In the future, the new experiment chamber will also be available for use by researchers from other scientific fields.
