This summer, the concentration of CO2 in the Earth's atmosphere reached 419 ppm, i.e. a 50% excess compared to the pre-industrial era. Air/liquid interfaces stabilized by surface-active molecules open new strategies for CO2 capture.

In order to limit global warming, several IPCC scenarios are based on an intensive capture of CO2 from the atmosphere in order to limit the greenhouse effect induced by it. This is a technically ambitious objective since it will require the development of processes that will allow the separation of CO2 from other gases in the atmosphere and its concentration in order to limit storage volumes. Aqueous foams in which gas is exchanged between bubbles allow this separation. The objective of this internship is to study at the scale of a single bubble the kinetics of CO2 transfer for various liquid film compositions.In order to limit global warming, several IPCC scenarios are based on an intensive capture of CO2 from the atmosphere in order to limit the greenhouse effect induced by it.
