|Abstract : Our research aims at characterizing the various dynamics, patterns and instabilities that can exist in out-of- equilibrium systems when chemical reactions are coupled to diffusion and convection. To do so, we develop combined experimental and theoretical approaches in a highly interdisciplinary environment at the interface between chemistry, physics, engineering and environmental sciences.
Specifically, we propose PhD research projects on
- Chemo-hydrodynamic pattern formation: The objective is to understand how to achieve spatio-temporal forcing of hydrodynamic patterns using the self-organizing power of dissipative reaction-diffusion processes. Using the fact that chemical reactions can trigger hydrodynamic flows by changing the density, viscosity or surface tension of solutions, we investigate how reaction-diffusion patterns can force and control modulations in space and time of convective flows.
- Influence of chemical reactions on CO2 sequestration: to reduce the amount of CO2 in the atmosphere, it is proposed to inject this gas in deep underground saline aquifers. Our research aims at understanding the influence of reactions and convective instabilities on the efficiency of this process.
- Convective instabilities in sea ice: Is sea ice a source or a sink for greenhouse gases (GHG) ? To answer such a question, we study the convective transport of GHG in sea ice by combined field scale measurements, laboratory-scale experimental studies and theoretical modeling.|
