Understanding the behavior of complex fluids
When a fluid (e.g. coffee or paint) dries on a surface, microscopic solid particles are dispersed, creating singular patterns depending on the fluid. How can we explain the origin of these different morphologies?
With the BOGUS project, a team from Montpellier's Charles Coulomb Laboratory is looking at a model system: colloidal gel beads. Scientists are seeking to better understand the microscopic and macroscopic behavior of the beads when subjected to two stresses: drying and extreme mechanical deformation. This area of study opens the way to understanding the behavior of complex fluids, such as blood coagulation or the spread of viruses by saliva... This report was produced and financed as part of the "Science Avec et Pour la Société" (SAPS) call for projects.

Our work is guided by the way scientists question the world around them and we translate their research into images to help people to understand the world better and to awaken their curiosity and wonderment.
