Worm-like instability of a vibrated sessile drop
Arnaud Hemmerle, Guillaume Froehlicher, Vance Bergeron +2
We study the effects of vertical sinusoidal vibrations on a liquid droplet with a low surface tension (ethanol) deposited on a solid substrate. In a precise range of amplitudes and…
Fracture of a model cohesive granular material
Alexander Schmeink, Lucas Goehring, Arnaud Hemmerle
We study experimentally the fracture mechanisms of a model cohesive granular medium consisting of glass beads held together by solidified polymer bridges. The elastic response of t…
A cohesive granular material with tunable elasticity
Arnaud Hemmerle, Matthias Schröter, Lucas Goehring
By mixing glass beads with a curable polymer we create a well-defined cohesive granular medium, held together by solidified, and hence elastic, capillary bridges. This material has…
Reduction in Tension and Stiffening of Lipid Membranes in an Electric Field Revealed by X-ray Scattering
Arnaud Hemmerle, Thierry Charitat, Giovanna Fragneto +1
The effect of AC electric fields on the elasticity of supported lipid bilayers has been investigated at the microscopic level using grazing incidence synchrotron x-ray scattering.…
