Recent and old stories from projects that are worth telling:
Welcome to the Marin Lab!We are based in the Physics of Fluids chair at the University of Twente, also part of the Max-Planck Center for Complex Fluid Dynamics.
We are a group of curious people interested in things living in confined systems: particles inside droplets, droplets inside channels, particles inside channels, bacteria inside droplets, people between walls or confined by white lines on the green grass. We are mainly driven by the observation of beautiful and very unexpected phenomena, and work very hard to describe them, sometimes we even manage to explain them! This is what drives our work.
So if you are a classifier-type, our work could be roughly classified somewhere between Physics and Engineering, Soft Matter also works for us!

Drying Teardrops
It all started many years ago: I was in the lab planning a droplet evaporation experiment and I added a tiny amount of salt to a particle solution to balance the liquid/particle density ratio. When I left the droplet to evaporate I could not believe it… the flow inside the droplet went exactly in the opposite direction as it should go, and I mean exactly in the three dimensions and three components!. Years after, my colleagues from the University of Granada showed me some funky ring-shaped stains that they observed in salty droplets, and they also had a good hypothesis for the flow inversion.
