A thermodynamic model of contact angle hysteresis [PDF]
The Journal of Chemical Physics, 2017 When a three-phase contact line moves along a solid surface, the contact angle no longer corresponds to the static equilibrium angle but is larger when the liquid is advancing and smaller when the liquid is receding. The difference between the advancing and receding contact angles, i.e., the contact angle hysteresis, is of paramount importance in ...

Apparent contact angle and contact angle hysteresis on liquid infused surfaces [PDF]
Soft Matter, 2017 The apparent contact angle and contact angle hysteresis of a droplet on liquid infused surfaces have strong dependence on the relative size between the droplet and its surrounding wetting ridge.

Studying of the Contact Angle Hysteresis on Various Surfaces
MATEC Web of Conferences, 2016 This paper is devoted to investigation of the contact angle hysteresis on various surfaces. It was carried out by two different methods: measuring the advancing and the receding contact angles and measuring the contact angles at water droplet evaporation

Contact angle hysteresis in a microchannel: Statics [PDF]
Physical Review Fluids, 2019 We study contact angle hysteresis in a chemically heterogeneous microchannel by tracking static meniscus configurations in the microchannel upon varying the volume of liquid. We first construct a graphical force balance similar to a previous approach by Joanny and de Gennes for this system, though here with a straight contact line.

On the lifetimes of evaporating droplets [PDF]
, 2014 The complete description of the lifetime of a droplet on a solid substrate evaporating in a 'stick–slide' mode is obtained. The unexpectedly subtle relationship between the lifetime of such a droplet and the lifetimes of initially identical droplets ...

Effect of contact angle hysteresis on measuring matric suction in unsaturated sandy soil
Geomatics, Natural Hazards & Risk, 2023 The contact angle plays an important role in matric suction of unsaturated soils, but few studies consider the effect of contact angle hysteresis on matric suction. In this paper, taking sandy soil as an example, the influence of contact angle hysteresis

The Possibility of Changing the Wettability of Material Surface by Adjusting Gravity
Research, 2020 The contact angle, as a vital measured parameter of wettability of material surface, has long been in dispute whether it is affected by gravity. Herein, we measured the advancing and receding contact angles on extremely low contact angle hysteresis ...
