A model of membrane deformations driven by a surface pH gradient
Toni V. Mendes, Jonas Ranft, Hélène Berthoumieux
Many cellular organelles are membrane-bound structures with complex membrane composition and shape. Their shapes have been observed to depend on the metabolic state of the organell…
Microfluidic free interface diffusion: measurement of diffusion coefficients and evidence of interfacial-driven transport phenomena
Hoang-Thanh Nguyen, Anne Bouchaudy, Jean-Baptiste Salmon
We have developed a microfluidic tool to measure the diffusion coefficient of solutes in an aqueous solution, by following the temporal relaxation of an initially steep concent…
Active Colloids in Harmonic Optical Potentials
Ivo Buttinoni, Lorenzo Caprini, Laura Alvarez +2
We study the motion of active patchy colloids in an optical trap using experiments, theory and numerical simulations. To achieve isotropic and harmonic confinement, we prototype mi…
Self-propelling colloidal finite state machines
Steven van Kesteren, Laura Alvarez, Silvia Arrese-Igor +2
Endowing materials with physical intelligence holds the key for a progress leap in robotic systems. In spite of the growing success for macroscopic devices, transferring these conc…
Near-critical spreading of droplets
Raphael Saiseau, Christian Pedersen, Anwar Benjana +4
We study the spreading of droplets in a near-critical phase-separated liquid mixture, using a combination of experiments, lubrication theory and finite-element numerical simulation…
Lift at low Reynolds number
Lionel Bureau, Gwennou Coupier, Thomas Salez
Lift forces are widespread in hydrodynamics. These are typically observed for big and fast objects, and are often associated with a combination of fluid inertia (i.e. large Reynold…
Non-Gaussian diffusion near surfaces
Arthur Alexandre, Maxime Lavaud, Nicolas Fares +6
We study the diffusion of particles confined close to a single wall and in double-wall planar channel geometries where the local diffusivities depend on the distance to the boundar…
Hydrodynamic Synchronisation of Chiral Microswimmers
Sotiris Samatas, Juho S. Lintuvuori
We study synchronization in bulk suspensions of spherical microswimmers with chiral trajectories using large scale numerics. The model is generic. It corresponds to the lowest orde…
Nanoparticle Taylor dispersion near charged surfaces with an open boundary
Alexandre Vilquin, Vincent Bertin, Elie Raphaël +3
The dispersive spreading of microscopic particles in shear flows is influenced both by advection and thermal motion. At the nanoscale, interactions between such particles and their…
Microfluidic osmotic compression of a charge-stabilized colloidal dispersion: Equation of state and collective diffusion coefficient
Camille Keita, Yannick Hallez, Jean-Baptiste Salmon
We show, using a model coupling mass transport and liquid theory calculations for a charge-stabilized colloidal dispersion, that diffusion significantly limits measurement times of…
Reorientation dynamics of microswimmers at fluid-fluid interfaces
Harinadha Gidituri, Zaiyi Shen, Alois Wurger +1
We study the orientational and translational dynamics of spherical microswimmers trapped at fluid interfaces, in terms of the force dipole and source dipole components of their flo…
