title = "Unsteady wetting on a rough surface due to electrically altered surface tension",
abstract = "Measurements of unsteady wetting on a rough surface were made. Spreading was initiated by electrically altering the solid-liquid 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. Flattening of the interface induced by pinning appears in the equations as 'slip' which lowers the effective capillary number.",

note = "Funding Information: The authors are indebted to Prof. Steven Garoff of the Physics Department at Carnegie Mellon University for advice and information on protocols and techniques developed in his lab which were of great help in establishing our experimental setup and methods. We further thank Prof. Garoff and his students Kroum Stoev and Qun Chen for sharing their data which we used to help calibrate our measurement system and evaluate our data. Our colleagues Steven H. Davis and Michael J. Miksis are thanked for their helpful advice. The financial support of the Office of Naval Research (N00014-92-1137) and the National Aeronautics and Space Administration (NAG3-1892) is acknowledged. We thank Ed P. Rood (ONR) and Mark M. Weislogel (NASA) for their encouragement.",
