Size limit for particle-stabilized emulsion droplets under gravity
Joe W. Tavacoli, Gijs Katgert, E. Grace Kim +2
We demonstrate that emulsion droplets stabilized by interfacial particles become unstable beyond a size threshold set by gravity. This holds not only for colloids but supra-colloid…
The Jamming Perspective on Wet Foams
Gijs Katgert, Brian P. Tighe, Martin van Hecke
Amorphous materials as diverse as foams, emulsions, colloidal suspensions and granular media can {\em jam} into a rigid, disordered state where they withstand finite shear stresses…
Jaming and Geometry of Two-Dimensional Foams
Gijs Katgert, Martin van Hecke
We experimentally probe the vicinity of the jamming point J, located at a density corresponding to random close packing (), in two dimensional, bidisperse pack…
Couette Flow of Two-Dimensional Foams
G. Katgert, B. P. Tighe, M. E. Möbius +1
We experimentally investigate flow of quasi two-dimensional disordered foams in Couette geometries, both for foams squeezed below a top plate and for freely floating foams. With th…
Flow in linearly sheared two dimensional foams: from bubble to bulk scale
Gijs Katgert, Andrzej Latka, Matthias E. Möbius +1
We probe the flow of two dimensional foams, consisting of a monolayer of bubbles sandwiched between a liquid bath and glass plate, as a function of driving rate, packing fraction a…
Relaxation and flow in linearly sheared two-dimensional foams
Matthias E. Möbius, Gijs Katgert, Martin van Hecke
We probe the relation between shear induced structural relaxation and rheology in experiments on sheared two-dimensional foams. The relaxation time, which marks the crossover to di…
