Sequence of images showing the formation of a bubble in a step emulsification device. The thickness of the left part of the device is small (typically 6 µm). The white gaseous neck is highly confined and stable, while in the right part of the device, the thickness is in the order of 100 µm and the gaseous neck is unstable due to Rayleigh Plateau instability and breaks into bubbles. Moreover, the continuous phase is degazed and the bubbles are blown using CO2 (highly soluble in degazed water) and tiny volume fraction of fluorinated gas insoluble in the continuous phase. The bubbles therefore empty until there is nearly no CO2 left inside of them thus forming nanobubbles of insoluble gas.

A fluorescent oil drop initially sitting on a flat surface is connected to a dark dry foam from above. The oil invades the liquid framework of the foam revealing its architecture. The oil and the surface active agents have been selected with great care so that the oil is not an antifoaming agent of the foam. Image width 4 cm.

Impact et mouillage de gouttes
Avec C. Planchette, O. Pitois, A.L.Biance, A. Delbos et D. Quéré, G. Brenn
- Mouillage et impact de gouttes sur des fibres coniques, cylindriques, inclinés.
- Impact de gouttes dans des trous et dans des pores
- Collision goutte/goutte

Two sequences of images illustrating the impact of a drop on a thin fibre (typically 500 microns in diameter). Depending on the relative distance between the drop center and the axis of the fiber, we either observe (bottom) centered impact where the droplet is sliced into two volumes of nearly equal size or an off-centered impact where the droplet is sliced into a big and a small volume. The small one is captured by the fiber. Thus the efficiency of the drop capture with a fiber critically depends on the geometry. More information in this article
