Bouncing granular damper

When an object hits the floor, if the object does not break, it rebounds… or not. At least, for sure, the object never comes back at the origin of the falling. Indeed, the brutal impact dissipates energy. Only one single … Continue reading

Solid-Hexatic-Liquid transitions in a granular monolayer

In our last paper published in Phys. Rev. E, we experimentally explored the behavior of a monolayer of millimetric beads interacting through short range magnetic dipole-dipole interactions. As the system is athermal, a mechanical agitation is used to produce an … Continue reading

Discharge of a silo in hypergravity

Last year, we performed a series of experiments to investigate the flow of an assembly of non-cohesive spherical grains in high gravity conditions. We studied the flow of beads out of a  silo that was loaded in one of the … Continue reading

Pulses in a vertical granular column

We investigated the dynamics of a vertical column of 12 beads submitted to a series of taps. Impulses are strong enough to eject beads. The motion of the beads are recorded using a high-speed camera. Depending on the frequency of taps, … Continue reading

3d printing revolution in the lab

Recent articles [1-3] emphasized the interest of 3d printing for scientists. In addition to pedagogical activities, during which students experience 3d models, scientific research can benefit a lot from such a technique. Scientists may build complex structures and may dream … Continue reading
