Measurements of unsteady wetting on a rough surface were made. Spreading was initiated by electrically altering the solidliquid surface tension. The resultant time-dependent interface shape could be described by steady theory augmented with an ad hoc model which accounts for surface roughness. Flatt

The instability of a meniscus due to a Marangoni flow is investigated in the case of a mixture of two liquids of different volatility and surface tension. We propose a theoretical description of this behavior which predicts the wavelength of the instability, in agreement with the experiments of Vuil

When a dilute colloidal suspension of 50-ยตm polyamide particles is exposed to a deformable interface, spontaneous flow occurs. This flow is orderly, reproducible, and shows a proportional dependence on particle concentration. The same type of flow was also observed in a silicon oil suspension. Placi
