Surface tension profiles in vertical soap films

Soap films are quite familiar objects that can be produced by simply pulling a frame out of a soapy water vessel. Carefully looking at this film reveals a horizontal succession of colored fringes. Those interferences fringes attest to both the … Continue reading

Optofluidic biosensors on fiber arrays

In earlier works [1,2], we proved that fiber arrays are the basis of an open digital microfluidics. Droplets can be manipulated on fibers and various processes such as droplet motion, fragmentation, trapping, release, mixing and encapsulation were studied on fiber … Continue reading

Filling a bouncing hollow ball

The bouncing ball problem was demonstrated to be a simple manner to experience chaotic behaviours. We studied a bouncing hollow ball which was filled with grains. On one hand, this procedure highly increases the number of freedom. On the other … Continue reading

Gas dissolution in antibubble dynamics

The lifetime of the antibubble is driven by the slow drainage of the air from the bottom to the top of the antibubble. We discover that there exists another channel that conducts to the thinning and the dead of the … Continue reading

Capillary-driven buoyancy

Usual 3D buoyancy in fluids results form a difference in density between the immersed object and its surroundings. A simple question is : what happens in a nearly 2D systems such as soap bubbles or soap films ? In such … Continue reading
