title: Spreading dynamics of water droplets
abstract: The spreading dynamics of water droplets on flat silicon surfaces is investigated. It is shown that, for situations close to complete wetting, the radius evolution with time can be described using a power law with a nonstandard exponent of 1/7. This dynamics is interpreted using a hydrodynamic model with an invariant dissipation profile. Such a description is also consistent with the slow dynamics observed for larger contact angles.
