Figure 7: Kinking and curling up of a chain.
From: Formation of printable granular and colloidal chains through capillary effects and dielectrophoresis
Three pearl-necklace chains composed of particles with a≈30 μm and formed in silicone oil (viscosity η=350 mPa s) at pulling speeds (a) 0.01, (b) 0.1 and (c) 1 mm s−1, respectively. (a) At low pulling speed, the chain remains stable after the field is turned off. At higher pulling speeds, it kinks (b) and curls up (c). Generally, the amount of excess liquid dragged with the chain depends on the pulling speed.
