Ultrasonic tracking of a sinking ball in a vibrated dense granular suspension
S. van den Wildenberg, X. Jia, J. Léopoldès +1
Observing and understanding the movement of an intruder through opaque dense suspensions such as quicksand remains a practical and conceptual challenge. Here we use an ultrasonic p…
Probing viscoelastic properties of a thin polymer film sheared between a beads layer and quartz crystal resonator
Julien Leopoldes, Xiaoping Jia
We report measurements of viscoelastic properties of thin polymer films of 10-100 nm at the MHz range. These thin films are confined between a quartz crystal resonator and a millim…
Drop dynamics on chemically patterned surfaces
H. Kusumaatmaja, J. Leopoldes, A. Dupuis +1
We compare numerical and experimental results exploring the behaviour of liquid drops moving across a surface patterned with hydrophobic and hydrophilic stripes. A lattice Boltzman…
Control of drop positioning using chemical patterning
A. Dupuis, J. Leopoldes, D. G. Bucknall +1
We explore how chemical patterning on surfaces can be used to control drop wetting. Both numerical and experimental results are presented to show how the dynamic pathway and equili…
Jetting Micron-Scale Droplets onto Chemically Heterogeneous Surfaces
J. Leopoldes, A. Dupuis, D. G. Bucknall +1
We report experiments investigating the behaviour of micron-scale fluid droplets jetted onto surfaces patterned with lyophobic and lyophilic stripes. The final droplet shape depend…
