Relaxation of a dewetting contact line Part 2: Experiments [PDF]
, 2007 The dynamics of receding contact lines is investigated experimentally through controlled perturbations of a meniscus in a dip coating experiment. We first characterize stationary menisci and their breakdown at the coating transition.

Contact angle hysteresis of a drop spreading over metal surfaces
MATEC Web of Conferences, 2016 The paper presents experimental data on the contact angle hysteresis of the distilled water drop spreading over the surfaces of non-ferrous metals. The measurements of the advancing and receding contact angles were carried out by method of sitting drop ...

A new model for contact angle hysteresis of superhydrophobic surface
AIP Advances, 2019 Contact angle hysteresis (CAH) is essential to characterize the wetting properties of a surface. But its underlying causes are not yet understood. A model relating to CAH is presented through mathematical deduction.

A Modified Contact Angle Measurement Process to Suppress Oil Drop Spreading and Improve Precision
Molecules, 2022 Static contact angle measurement is a widely applied method for wettability assessment. Despite its convenience, it suffers from errors induced by contact angle hysteresis, material heterogeneity, and other factors.

Drops with non-circular footprints [PDF]
, 2015 In this paper we study the morphology of drops formed on partially wetting substrates, whose footprint is not circular. This type of drops is a consequence of the breakup processes occurring in thin films when anisotropic contact line motions take place.

Memory of the Unjamming Transition during Cyclic Tiltings of a Granular Pile [PDF]
, 2005 Discrete numerical simulations are performed to study the evolution of the micro-structure and the response of a granular packing during successive loading-unloading cycles, consisting of quasi-static rotations in the gravity field between opposite ...

A new model for contact angle hysteresis
Networks & Heterogeneous Media, 2007 We present a model which explains several experimental observations relating contact angle hysteresis with surface roughness. The model is based on the balance between released capillary energy and dissipation associated with motion of the contact line: it describes the stick–slip behavior of drops on a rough surface using ideas similar to those ...
