Relaxation of a dewetting contact line Part 1: A full-scale hydrodynamic calculation
, 2007 The relaxation of a dewetting contact line is investigated theoretically in the so-called "Landau-Levich" geometry in which a vertical solid plate is withdrawn from a bath of partially wetting liquid.

A Variational Approach to Contact Angle Saturation and Contact Line Instability in Static Electrowetting [PDF]
The Quarterly Journal of Mechanics and Applied Mathematics, 2009 Drops of a conducting fluid in electrowetting devices tend to spread when a difference of potential V o is set between the drop and an electrode external to it. The classical Lippmann theory predicts unlimited spreading, with a decrease of the contact angle between drop and solid substrate, as one increases V 0 .
