Are Contact Angle Measurements Useful for Oxide-Coated Liquid Metals?
Langmuir, 2021 This work establishes that static contact angles for gallium-based liquid metals have no utility despite the continued and common use of such angles in the literature.

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

On the Dynamic Contact Angle in Capillary Flows [PDF]
Journal of Chemical and Petroleum Engineering, 2021 The displacement of the contact line (CL) between two arbitrary immiscible flowing fluids was modeled. The present model is valid for a wide range of viscosity ratios of the phases. This is while the previously developed models reported in the literature

Surface mobility and structural transitions of poly(n-alkyl methacrylates) probed by dynamic contact angle measurements [PDF]
, 1986 Dynamic contact angles and contact-angle hysteresis of a series of poly(n-alkyl methacrylates) (PAMA) were investigated using the Wilhelmy plate technique.

Contact-Angle Hysteresis and Contact-Line Friction on Slippery Liquid-like Surfaces
Langmuir, 2020 Contact-line pinning and dynamic friction are fundamental forces that oppose the motion of droplets on solid surfaces. Everyday experience suggests that if a solid surface offers low contact-line pinning, it will also impart a relatively low dynamic ...

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 ...

Mathematical model of dynamic imbibition in nanoporous reservoirs
Petroleum Exploration and Development, 2022 The oil-water imbibition equation in the nano-scale pores considering the dynamic contact angle effect, nanoconfinement effect, inertia effect, and inlet end effect was established, and the relation between the friction coefficient of solid-oil-water ...
