Deposit Growth in the Wetting of an Angular Region with Uniform Evaporation
Rui Zheng, Yuri O. Popov, Thomas A. Witten
Solvent loss due to evaporation in a drying drop can drive capillary flows and solute migration. The flow is controlled by the evaporation profile and the geometry of the drop. We…
Chain-reaction cascades in surfactant monolayer buckling
A. Gopal, V. A. Belyi, H. Diamant +2
Certain surfactant monolayers at the water-air interface have been found to undergo, at a critical surface pressure, a dynamic instability involving multiple long folds of micron w…
Surface charge relaxation and the pearling instability of charged surfactant tubes
T. T. Nguyen, A. Gopal, K. Y. C. Lee +1
The pearling instability of bilayer surfactant tubes was recently observed during the collapse of fluid monolayers of binary mixtures of DMPCPOPG and DPPCPOPG surfactants. We…
Crescent Singularities in Crumpled Sheets
Tao Liang, Thomas A. Witten
We examine the crescent singularity of a developable cone in a setting similar to that studied by Cerda et al [Nature 401, 46 (1999)]. Stretching is localized in a core region near…
