Shear dynamics of confined membranes
Thomas Le Goff, Tung B. T. To, Olivier Pierre-Louis
We model the nonlinear response of a lubricated contact composed of a two-dimensional lipid membrane immersed in a simple fluid between two parallel flat and porous walls under she…
The Nonequilibrium Crystallization Force
Luca Gagliardi, Olivier Pierre-Louis
The forces exerted by growing crystals on the surrounding materials play a major role in many geological processes, from diagenetic replacement to rock weathering and uplifting of…
Confined Growth with slow surface kinetics: a Thin Film Model approach
Luca Gagliardi, Olivier Pierre-Louis
Recent experimental and theoretical investigations of crystal growth from solution in the vicinity of an impermeable wall have shown that: (i) growth can be maintained within the c…
Adhesion dynamics of confined membranes
Tung B. T. To, Thomas Le Goff, Olivier Pierre-Louis
We report on the modeling of the dynamics of confined lipid membranes. We derive a thin film model in the lubrication limit which describes an inextensible liquid membrane with ben…
Crystal growth in nano-confinement: Subcritical cavity formation and viscosity effects
Luca Gagliardi, Olivier Pierre-Louis
We report on the modeling of the formation of a cavity at the surface of crystals confined by a flat wall during growth in solution. Using a continuum thin film model, we discuss t…
Thin film modeling of crystal dissolution and growth in confinement
Luca Gagliardi, Olivier Pierre-Louis
We present a continuum model describing dissolution and growth of a crystal contact confined against a substrate. Diffusion and hydrodynamics in the liquid film separating the crys…
Transition to coarsening for confined one-dimensional interfaces with bending rigidity
Thomas Le Goff, Paolo Politi, Olivier Pierre-Louis
We discuss the nonlinear dynamics and fluctuations of interfaces with bending rigidity under the competing attractions of two walls with arbitrary permeabilities. This system mimic…
Frozen states and order-disorder transition in the dynamics of confined membranes
Thomas Le Goff, Paolo Politi, Olivier Pierre-Louis
The adhesion dynamics of a membrane confined between two permeable walls is studied using a two-dimensional hydrodynamic model. The membrane morphology decomposes into adhesion pat…
Giant Slip at Liquid-Liquid Interfaces Using Hydrophobic Ball Bearings
Quentin Ehlinger, Laurent Joly, Olivier Pierre-Louis
Liquid-gas-liquid interfaces stabilized by hydrophobic beads behave as ball bearings under shear and exhibit a giant slip. Using a scaling analysis and molecular dynamics simulatio…
Fully reversible transition from Wenzel to Cassie-Baxter states on corrugated superhydrophobic surfaces
R. J. Vrancken, H. Kusumaatmaja, K. Hermans +4
Liquid drops on textured surfaces show different dynamical behaviors depending on their wetting states. They are extremely mobile when they are supported by composite solid-liquid-…
Stiff knots
R. Gallotti, O. Pierre-Louis
We report on the geometry and mechanics of knotted stiff strings. We discuss both closed and open knots. Our two main results are: (i) Their equilibrium energy as well as the equil…
