Surface mobility of a glass-forming polymer in an ionic liquid
Xinyu Zhang, Christian Pedersen, Haoqi Zhu +6
The free surface of glassy polymers exhibits enhanced segmental dynamics compared to the bulk, forming a liquid-like layer that lowers the glass transition temperature (Tg) in nano…
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…
Equivalent circuit and continuum modeling of the impedance of electrolyte-filled pores
Christian Pedersen, Timur Aslyamov, Mathijs Janssen
Batteries, supercapacitors, and several other electrochemical devices charge by accumulating ions in the pores of electrolyte-immersed porous electrodes. The charging of such devic…
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…
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…
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
T. S. Chan, C. Pedersen, J. Koplik +1
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…
Soft nanobubbles can deform rigid glasses
Shuai Ren, Christian Pedersen, Andreas Carlson +2
Confined glasses and their anomalous interfacial rheology raise important questions in fundamental research and numerous practical applications. In this Letter, we study the influe…
Asymptotic regimes in elastohydrodynamic and stochastic leveling on a viscous film
Christian Pedersen, John Niven, Thomas Salez +2
An elastic sheet that deforms near a solid substrate in a viscous fluid is a situation relevant to various dynamical processes in biology, geophysics and engineering. Here, we stud…
