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

Effect of contact angle hysteresis on thermocapillary droplet actuation [PDF]
, 2005 Open microfluidic devices based on actuation techniques such as electrowetting, dielectrophoresis, or thermocapillary stresses require controlled motion of small liquid droplets on the surface of glass or silicon substrates.

The Role of Contact Angle Hysteresis for Fluid Transport in Wet Granular Matter [PDF]
, 2015 The stability of sand castles is determined by the structure of wet granulates. Experimental data about the size distribution of fluid pockets are ambiguous about their origin.

A simple method to create superhydrophobic aluminium surfaces [PDF]
, 2012 Superhydrophobic surfaces were prepared using a very simple and low-cost method by spray coating. A high static water contact angle of about 154° was obtained by deposition of stearic acid on an aluminium alloy.

Tunable contact angle hysteresis by micropatterning surfaces [PDF]
Applied Physics Letters, 2011 Lithography is used to form circular micropatterns which govern the evaporation of a water droplet. The surfaces are composed of concentric circular defects having a smooth indentation profile. When a droplet encounters a micropattern, evaporation occurs with distinct discontinuities in the droplet wetting contact angle and base radius. The addition of

Lattice Boltzmann modeling of contact angle and its hysteresis in two-phase flow with large viscosity difference [PDF]
, 2015 Contact angle hysteresis is an important physical phenomenon omnipresent in nature and various industrial processes, but its effects are not considered in many existing multiphase flow simulations due to modeling complexity.

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 ...
