Bubbles dissolution, compression

In these studies, we were interested in the compressive behaviour of particle-laden interfaces.

Using X-rays, we probed the adsorption and rearrangements occuring at an oil-water interface with ligand-grafted nanoparticles adsorbed [10]. We showed a two-stage adsorption mechanism. Under compression at different speeds, the interface behaved differently. For slow compression, the ligands have time to rearrange and allo for smaller interparticle distances before buckling of the monolayer.

We also looked at the temperature-induced dissolution of bubbles covered with clay particles [8]. Those bubbles were shown to be extremely stable (tens of hours) and resistant to complex temperature variations.
