Crowding-Regulated Binding of Divalent Biomolecules
Tomasz Skóra, Mathijs Janssen, Andreas Carlson +1
Macromolecular crowding affects biophysical processes as diverse as diffusion, gene expression, cell growth, and senescence. Yet, there is no comprehensive understanding of how cro…
Coalescence of elastic blisters filled with a viscous fluid
Torstein Sæter, Christian Pedersen, Jacco H. Snoeijer +2
Pockets of viscous fluid coalescing beneath an elastic plate are encountered in a wide range of natural phenomena and engineering processes, spanning across scales. As the pockets…
Static wetting of a barrel-shaped droplet on a soft-layer-coated fiber
Bo Xue Zheng, Christian Pedersen, Andreas Carlson +1
A droplet can deform a soft substrate due to capillary forces when they are in contact. We study the static deformation of a soft solid layer coated on a rigid cylindrical fiber wh…
Instability and rupture of sheared viscous liquid nanofilms
Vira Dhaliwal, Christian Pedersen, Kheireddine Kadri +5
Liquid nanofilms are ubiquitous in nature and technology, and their equilibrium and out-of-equilibrium dynamics are key to a multitude of phenomena and processes. We numerically st…
Influence of wind on a viscous liquid film flowing down a thread
Annette Cazaubiel, Andreas Carlson
We investigate experimentally the effect of wind on the dynamics of a viscous liquid film flowing down a thread. The liquid film is well-known to destabilize into an axisymmetric b…
Surface and Bulk Relaxation of Vapour-Deposited Polystyrene Glasses
Junjie Yin, Christian Pedersen, Michael Thees +3
We have studied the liquid-like response of the surface of vapour-deposited glassy films of polystyrene to the introduction of gold nanoparticles on the surface. The build-up of po…
Sliding, vibrating and swinging droplets on an oscillating fibre
Stéphane Poulain, Andreas Carlson
We study experimentally the dynamics of a water droplet on a tilted and vertically oscillating rigid fibre. As we vary the frequency and amplitude of the oscillations the droplet t…
Engulfment of a drop on solids coated by thin and thick fluid films
Chunheng Zhao, Vanessa R. Kern, Andreas Carlson +1
When an aqueous drop contacts an immiscible oil film, it displays complex interfacial dynamics. Upon contact the oil spreads onto the drop's liquid-air interface, first forming a c…
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…
Experimental and numerical investigation of bubble migration in shear flow: deformability-driven chaining and repulsion
Blandine Feneuil, Kazi Tassawar Iqbal, Atle Jensen +3
We study the interaction-induced migration of bubbles in shear flow and observe that bubbles suspended in elastoviscoplastic emulsions organise into chains aligned in the flow dire…
Viscoplastic sessile drop coalescence
Vanessa R. Kern, Torstein Sæter, Andreas Carlson
The evolution of the liquid bridge formed between two coalescing sessile yield-stress drops is studied experimentally. We find that the height of the bridge evolves similar to a vi…
Growth of a viscoplastic blister underneath an elastic sheet
Torstein Sæter, Olivier Galland, Blandine Feneuil +1
Inspired by the formation of geological structures as earth's crust deforms by magmatic intrusions, we investigate the elastohydrodynamic growth of a viscoplastic blister under an…
Elastic modulus measurements of cooked Lutefisk
Blandine Feneuil, Eirik Strøm Lillebø, Christian Larris Honstad +2
Lutefisk is a traditional Norwegian Christmas dish, made of dry cod soaked in a lye solution before re-hydrated. We report measurements of the tissue softness of cooked Lutefisk. S…
Multiple droplets on a conical fiber: formation, motion, and droplet mergers
Carmen L. Lee, Tak Shing Chan, Andreas Carlson +1
Small droplets on slender conical fibers spontaneously move along the fiber due to capillary action. The droplet motion depends on the geometry of the cone, the surface wettability…
Droplet settling on solids coated with a soft layer
Stéphane Poulain, Andreas Carlson
Gravitational settling of a droplet in air onto a soft substrate is a ubiquitous event relevant to many natural processes and engineering applications. We study this phenomenon by…
Nanobubble-induced flow of immersed glassy polymer films
Christian Pedersen, Shuai Ren, Yuliang Wang +2
We study the free-surface deformation dynamics of an immersed glassy thin polymer film supported on a substrate, induced by an air nanobubble at the free surface.We combine analyti…
Universal Self-Similar Attractor in the Bending-Driven Leveling of Thin Viscous Films
Christian Pedersen, Thomas Salez, Andreas Carlson
We study theoretically and numerically the bending-driven leveling of thin viscous films within the lubrication approximation. We derive the Green's function of the linearized thin…
Film coating by directional droplet spreading on fibers
Tak Shing Chan, Carmen L. Lee, Christian Pedersen +2
Plants and insects use slender conical structures to transport and collect small droplets, which are propelled along the conical structures due to capillary action. These droplets…
Film deposition of a self-propelled droplet on a cone with slip

We study the dynamic wetting of a self-propelled viscous droplet using the time-dependent lubrication equation on a conical-shaped substrate for different cone radii, cone angles a…
Destabilization and phase separation of particle suspensions in emulsions
Blandine Feneuil, Atle Jensen, Andreas Carlson
Yield stress fluids are widely used in industrial application to arrest dense solid particles, which can be studied by using a concentrated emulsion as a model fluid. We show in ex…

Curving to fly: Synthetic adaptation unveils optimal flight performance of whirling fruits
Jean Rabault, Richard A. Fauli, Andreas Carlson
Appendages of seeds, fruits and other diaspores (dispersal units) are essential for their wind dispersal, as they act as wings and enable them to fly. Whirling fruits generate an a…
