Hypothesis Droplet wetting on a solid substrate is affected by the surface heterogeneity.
Introducing patterned wettability on the solid substrate is expected to engender anisotropic …

Wetting Phenomena: Line Tension and Gravitational Effect

F Wang, H Zhang, B Nestler - Physical Review Letters, 2024 - APS
An apparent contact angle is formed when a droplet is deposited on a solid substrate.
Young's law has been employed to describe the equilibrium contact angle. Often in …

Line tension of sessile droplets: Thermodynamic considerations

H Zhang, F Wang, B Nestler - Physical Review E, 2023 - APS
We deduce a thermodynamically consistent diffuse interface model to study the line tension
phenomenon of sessile droplets. By extending the standard Cahn-Hilliard model via …
