Confined Multilamellae Prefer Cylindrical Morphology
Jung-Ren Huang, Ling-Nan Zou, Thomas A. Witten
By evaporating a drop of lipid dispersion we generate the myelin morphology often seen in dissolving surfactant powders. We explain these puzzling nonequilibrium structures using a…
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…
Characteristic Angles in the Wetting of an Angular Region: Deposit Growth
Yuri O. Popov, Thomas A. Witten
As was shown in an earlier paper [1], solids dispersed in a drying drop migrate to the (pinned) contact line. This migration is caused by outward flows driven by the loss of the so…
Topography and instability of monolayers near domain boundaries
H. Diamant, T. A. Witten, C. Ege +2
We theoretically study the topography of a biphasic surfactant monolayer in the vicinity of domain boundaries. The differing elastic properties of the two phases generally lead to…
