Capillary origami: spontaneous wrapping of a droplet with an elastic sheet
C. Py, P. Reverdy, L. Doppler +3
The interaction between elasticity and capillarity is used to produce three dimensional structures, through the wrapping of a liquid droplet by a planar sheet. The final encapsulat…
Fluctuations of a driven membrane in an electrolyte
D. Lacoste, M. Cosentino Lagomarsino, JF. Joanny
We develop a model for a driven cell- or artificial membrane in an electrolyte. The system is kept far from equilibrium by the application of a DC electric field or by concentratio…
Comment on ``Large Slip of Aqueous Liquid Flow over a Nanoengineered Superhydrophobic Surface'' by C-H Choi and C Kim
Lyderic Bocquet, Patrick Tabeling, Sebastien Manneville
In a recent Letter (Phys. Rev. Lett. vol 96, 066001 (2006), ref [1]), Choi and Kim reported slip lengths of a few tens of microns for water on nanoengineered superhydrophobic surfa…
Accumulating Particles at the Boundaries of a Laminar Flow
Michael Schindler, Peter Talkner, Marcin Kostur +1
The accumulation of small particles is analyzed in stationary flows through channels of variable width at small Reynolds number. The combined influence of pressure, viscous drag an…
Kinetics of bond formation in crosslinked gelatin gels
T. Abete, E. Del Gado, D. Hellio Serughetti +3
In chemical crosslinking of gelatin solutions, two different time scales affect the kinetics of the gel formation in the experiments. We complement the experimental study with Mont…
Phases of granular segregation in a binary mixture
Pedro M. Reis, Tim Sykes, Tom Mullin
We present results from an extensive experimental investigation into granular segregation of a shallow binary mixture in which particles are driven by frictional interactions with…
