Solid adsorption: the missing mechanism for surfactant contact lines -- a phase-field approach
Parvathy K. Kannan, Kazi T. Iqbal, Diego DÃaz +5
We develop a thermodynamically consistent phase-field model for soluble surfactants in two-phase flows, incorporating both interfacial and solid surface adsorption. The model is de…

Stood-up drop to measure receding contact angles
Diego DÃaz, Aman Bhargava, Franziska Walz +9
The wetting behavior of drops on natural and industrial surfaces is determined by the advancing and receding contact angles. They are commonly measured by the sessile drop techniqu…

Surfactants Screen Slide Electrification
Xiaomei Li, Zhongyuan Ni, Xiaoteng Zhou +4
Water drops spontaneously accumulate charges when they move on hydrophobic dielectric surfaces by slide electrification. On the one hand, slide electrification generates electricit…
