Dynamical shapes of droplets of cyclodextrin/surfactants solutions

We present a series of experiments with droplets of aqueous cyclodextrin-surfactant solutions, in which the volume is reduced after the equilibrium spherical shape is reached. The fnal shape of the drop after this perturbation is found to be dependent on the concentration of inclusion complexes in t...

The fnal shape of the drop after this perturbation is found to be dependent on the concentration of inclusion complexes in the bulk of the solution.

Dipole-dipole interactions on the surface of the drop trigger a competition between water surface tension and dipole-dipole interaction energies.
