A team from LIPhy has studied the transport of CO2 within a liquid foam in contact with the atmosphere and shown how its effective diffusion in the medium emerges from the coupling between the structure of the foam and the transport of the gas through the soap films. This study paves the way for the development of low-cost CO2 filtration systems based on the ability of this main contributor to the greenhouse effect to dissolve more easily in water than most other gases.

LIPhy is taking action to reduce the share of equipment purchases in its CO2 emissions! Over the past year, the laboratory has developed and implemented a new digital tool for sharing equipment: the Matosthèque.

Dental sensitivity is unique in that it is mediated by cells called odontoblasts, located in the dental pulp at the center of the tooth. According to hydrodynamic theory, the activation of odontoblastic processes is linked to the movement of fluids in the dentinal porosity induced by external stimuli. A new study conducted at the Interdisciplinary Laboratory of Physics (LIPhy - CNRS/UGA) shows that this porosity has all the characteristics of a complex network. Far from functioning as independent sensors, odontoblasts could therefore, in theory, adopt collective behaviors that are very different from the simple sum of individual responses.
