Non-equilibrium configurations of swelling polymer brush layers induced by spreading drops of weakly volatile oil
Özlem Kap, Simon Hartmann, Harmen Hoek +4
Polymer brush layers are responsive materials that swell in contact with good solvents and their vapors. We deposit drops of an almost completely wetting volatile oil onto an oleop…
Absence of anomalous underscreening in highly concentrated aqueous electrolytes confined between smooth silica surfaces
Saravana Kumar, Peter Cats, Mohammed B. Alotaibi +5
Recent experiments and a series of subsequent theoretical studies suggest the occurrence of universal underscreening in highly concentrated electrolyte solutions. We performed a se…
Roughness Induced Rotational Slowdown Near the Colloidal Glass Transition
Beybin Ilhan, Frieder Mugele, Michael H. G. Duits
Roughening the surface of spherical colloids can drastically change their translational and rotational dynamics in dense suspensions. Using 3D confocal microscopy, we show that rou…
Characterizing the fluid-matrix affinity in an organogel from the growth dynamics of oil stains on blotting paper
Qierui Zhang, Frieder Mugele, Piet M. Lugt +1
Grease, as used for lubrication of rolling bearings, is a two-phase organogel that slowly releases oil from its gelator matrix. Because the rate of release determines the operation…
Behaviour of flexible superhydrophobic striped surfaces during (electro-)wetting of a sessile drop
Arvind Arun Dev, Ranabir Dey, Frieder Mugele
We study here the microscopic deformations of elastic lamellae constituting a superhydrophobic substrate under different wetting conditions of a sessile droplet using electrowettin…
Soft electrowetting
Ranabir Dey, Mathijs van Gorcum, Frieder Mugele +1
Electrowetting is a commonly used tool to manipulate sessile drops on hydrophobic surfaces. By applying an external voltage over a liquid and a dielectric-coated surface, one achie…
