Offer Description
Chemical cycles operating in Earth's atmosphere are responsible for many important phenomena, and have major consequences for air pollution, climate change and the evolution of the atmosphere over time. Some of the reactions within these cycles exhibit isotopic fractionation. This process leaves a fingerprint on the products of these reactions. If records of these products are preserved, as in the case of ice cores, for example, the isotopic analysis of these records can provide vital information about how Earth's past environment changed over time.
Current developments in clumped isotopic chemical analysis techniques should provide chemical information of unprecedented detail, allowing us to understand isotopic enrichment on the scale of chemical bond rather than bulk samples. The goal of this project is to study selected cycles involving sulphur and nitrogen chemistry in several reaction chambers: HELIOS (CNRS, Orléans) and CESAM (UPEC, Paris). Both of these chambers are uniquely well-equipped to understand atmospheric chemical composition in fine detail, which will be used to develop detailed atmospheric degradation mechanisms. At the same time, isotopic composition will be studied using a state-of-the-art orbitrap technique, which will be used for isotopic analysis in collaboration with Institut de Geosciences de l'Environnement (Grenoble).
The Atmospheric Reactivity group at ICARE-CNRS in Orléans has developed the largest atmospheric simulation chamber using natural irradiation in France and the third largest in Europe, HELIOS (cHambrE de simuLation atmosphérique à Irradiation naturel d'Orléans). Both of these chambers are uniquely well-equipped to understand atmospheric chemical composition in fine detail, which will be used to develop detailed atmospheric degradation mechanisms.
The candidate will be responsible for experiments in an atmospheric simulation chamber and processing of data from instruments on the analytical platform.
The CNRS ICARE laboratory in Orléans carries out research in the fields of combustion chemistry and physics, propulsion plasmas and atmospheric and environmental chemistry. The total number of staff is around 100, including 17 permanent scientists and 16 academics. The research activities of the Atmospheric Reactivity (RA) group deal mainly with laboratory and field studies of the gas phase and heterogeneous chemical processes of interest in the troposphere. RA is also associated with the Observatoire des sciences de univers en région Centre, one of the institutes of the University of Orléans, and belongs to the French national network of earth and space observatories Sciences (INSU-CNRS). It has access to the various OSUC laboratories and facilities.
