A single length scale rules ballistic aggregation: travels of a droplet train
Nathan Vani, Stefan Kooij, Aritro Mukherjee +3
Ballistic aggregation is a canonical non-equilibrium process, relevant across scales from granular gases to planetary accretion. Collisions are driven by differences in velocities,…
Polarity-dependent Electroadhesion at Silicon Interfaces with Nanoscale Roughness
Liang Peng, Stefan Kooij, HT Ciftci +2
We measure and model electroadhesion across multi-asperity silicon interfaces with nanometer scale roughness. When electrically biased, our naturally oxidized silicon interfaces di…
Transition from viscoelastic to fracture-like peeling of pressure-sensitive adhesives
Marion Grzelka, Stefan Kooij, Sander Woutersen +2
We investigate the process of the slow unrolling of a roll of typical pressure-sensitive adhesive, Scotch tape, under its own weight. Probing the peeling velocities down to nm/s re…
Mechanical properties of fat-based semi solid heterogeneous materials
Henri de Cagny, Stefan Kooij, Theo Blijdenstein +3
Fat based pasty products are an essential part of food industries, both as process intermediate or end products. Such materials are made of a continuous fat phase in which solid pa…
Evaporation of dilute sodium dodecyl sulfate droplets on a hydrophobic substrate
Wojciech Kwieciński, Tim Segers, Sjoerd van der Werf +4
Evaporation of surfactant laden sessile droplets is omnipresent in nature and industrial applications such as inkjet printing. Soluble surfactants start to form micelles in an aque…
Characterizing nonaffinity upon decompression of soft-sphere packings
Stefan Kooij, Edan Lerner
Athermal elastic moduli of soft sphere packings are known to exhibit universal scaling properties near the unjamming point, most notably the vanishing of the shear-to-bulk moduli r…
Unjamming in models with analytic pairwise potentials
Stefan Kooij, Edan Lerner
The canonical models for studying the unjamming scenario in systems of soft repulsive particles assume pairwise potentials with a sharp cut-off in the interaction range. The sharp…
