The way antifoaming agents act

In many industrial processes, foams are unwanted products. In order to destroy them, antifoaming agents are used… without really knowing how they act. Those antifoaming agents are dispersions of small particles, which need to break foam films efficiently. We have … Continue reading

Foamability

In earlier works [1,2], we have developed a method for measuring the foamability of liquid solutions. The liquid is placed in a Hele-Shaw cell which is flipped several times, thus generating a 2D foam. By analyzing the pictures of the … Continue reading

Faraday instability at foam/water interface

Foams are common fluid entities of our everyday life. Our group is, among others, involved in ESA projects on the foam generation and stability under microgravity [1]. On Earth, the gravitational drainage dries the foam such that an interface between … 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

News from the ISS

The GRASP is participating to the FOAM-S experiment [1,2], which aims to study the influence of microgravity on the foamability of liquid solutions.  The experiment benefited from a flight opportunity to the International Space Station (ISS) in 2009 during the stay … Continue reading
