Journal ArticleDOI
Mechanically robust nanoparticle stabilized transparent liquid marbles
TL;DR: In this article, the authors used liquid evaporation data and environmental scanning electron microscope images to demonstrate that their robustness may be attributed to a nanoparticulate elastic thin film that self-assembles on the liquid-vapor interface.
Journal ArticleDOI
Comment on How Wenzel and Cassie Were Wrong by Gao and McCarthy.
Journal ArticleDOI
Evaporating drops on patterned surfaces: Transition from pinned to moving triple line
TL;DR: The dimensionless evaporation rate constant is found to be higher during the moving TL phase in comparison with the pinned TL phase, and it is found that the triple line topology has no effect on the evapation rate constant.
Journal ArticleDOI
Effect of three-phase contact line topology on dynamic contact angles on heterogeneous surfaces.
Neeharika Anantharaju,Mahesh V. Panchagnula,Srikanth Vedantam,Sudhakar Neti,Svetlana Tatic-Lucic +4 more
TL;DR: It is reported that the contact angle is independent of area void fraction for surfaces with microcavities, which correspond to situations when the advancing contact line is continuous, in contrast with Cassie-Baxter theory, which uses areavoid fraction as the determining parameter, regardless of the type of roughness.
Journal ArticleDOI
On the three‐dimensional instability of a swirling, annular, inviscid liquid sheet subject to unequal gas velocities
TL;DR: In this paper, a linear model describing the instability behavior of annular, swirling, inviscid sheets subject to inner and outer gas flows of differing velocities is presented.
