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 Jérôme Gabathuler

Join me in welcoming Jérôme, our new PhD-student in Markus Ammann's group.

He got his master in applied physics at the EPF Lausanne. During his master thesis, he worked on "Solar water purification using photocatalysis with a novel TiO2 nano-porous aerogel“. At PSI, Jérôme Gabathuler will be studying the surface of ice samples using X-ray excited electron spectroscopy at the Near Ambient Pressure Photoemission (NAPP) endstation at SLS. His thesis work is part of the SNF funded project entitled "Interfacial Chemistry of Ice: Photolysis and Acid-Base Equilibria in the QLL and Brine“.

LUC Excursion Sargans.JPG

LUC goes underground

During this year's excursion we experienced the underground world on a guided tour through the Gonzen iron mine in Sargans. While walking up and down the impressive system of galleries and tunnels the extreme working conditions of the miners became palpable. After the 3.5 hours underground we happily returned to our labs at PSI.

Welcome Jonas Stegmaier

We warmly welcome Jonas Stegmaier in the Laboratory of Environmental Chemistry. He joined the Analytical Chemistry group on 1 July 2018.

Jonas Stegmaier studied Geology with a specialisation in Geochemistry at the Albert-Ludwigs-Universität Freiburg in Germany. During his master thesis he determined element and ion concentrations in river water for tracing hydrochemistry of contrasting, merging streams in South-West Germany.

At PSI, Jonas Stegmaier will be characterizing the performance of a new Inductively Coupled Plasma Time Of Flight Mass Spectrometer for trace element analysis in ice cores with the final goal to reconstruct Saharan dust transports and heavy metal pollution from metallurgy in Europe over the last 2000 years.
