Capillary Waves Found Between Fully Miscible Fluids

Capillary waves—tiny ripples normally seen only at the sharp boundary between liquids that do not mix—have now been observed between liquids that do mix completely. Using microfluidic experiments, researchers around SoftComp partner CNRS-Montpellier... (Read more)

Figure: Unified state diagram for the fluidization transition. For small deformation amplitudes, soft systems exhibit solid-like dynamics (blue points) with low fluidity, namely very large spontaneous relaxation times. As the deformation amplitude increases, soft systems undergo the fluidization transition (gray points), characterized by the coexistence of two types of dynamics (solid and fluid). They are eventually fluidized at very large deformations, where the microscopic dynamics resemble those of a liquid. (Copyright © 2023: the authors)
