Query: Slippage of Newtonian liquids: Influence on the dynamics of dewetting
  thin films   Slippage of Newtonian liquids in the presence of a solid substrate is a newly
found phenomenon the origin of which is still under debate. In this paper, we
present a new analysis method to extract the slip length. Enhancing the slip of
liquids is an important issue for microfluidic devices that demand for high
throughput at low pumping power. We study the velocity of short-chained liquid
polystyrene (PS) films dewetting from non-wettable solid substrates. We show
how the dynamics of dewetting is influenced by slippage and we compare the
results of two types of substrates that give rise to different slip lengths. As
substrates, Si wafers were used that have been coated by
octadecyl-trichlorosilane (OTS) or dodecyl-trichlorosilane (DTS), respectively.
Our results demonstrate that the dewetting velocity for PS films on DTS is
significantly larger than on OTS and that this difference originates from the
different slip lengths of the liquid on top of the two surfaces. For PS films
of thicknesses between 130 nm and 230 nm we find slip lengths between 400 nm
and 600 nm, depending on substrate and temperature.
