| Sedimentation | - Movies |
The movies on this webpage are from a joint collaboration of Paddy Royall, Joachim Dzubiella, Matthias Schmidt, and Alfons van Blaaderen and are obtained (by Paddy!) with confocal microscopy of sedimenting colloidal particles.
Movie 1 (mov,
avi file format):
Time-evolution of the Rayleigh-Taylor-like instability of a
sedimenting dispersion. The field of view is 225x70microns; the
playback speed is accelerated by a factor of 48. The image (xz) plane
is upright such that gravity points along the vertical direction. The
initial state is an equilibrated sample turned upside down.
Movie 2 (mov,
avi file format):
Time-evolution of the lateral structure of the dispersion exhibiting a
Rayleigh-Taylor-like instability. The field of view is 145x145 microns
and playback is accelerated by a factor of 60. The image (xy) plane
lies flat.
