How not to let CO2 bubbles over in the air

A team from LIPhy has studied the transport of CO2 within a liquid foam in contact with the atmosphere and shown how its effective diffusion in the medium emerges from the coupling between the structure of the foam and the transport of the gas through the soap films. This study paves the way for the development of low-cost CO2 filtration systems based on the ability of this main contributor to the greenhouse effect to dissolve more easily in water than most other gases.
