By designing and implementing a new experimental method, we have measured the dynamic advancing and receding contact angles and the resulting hysteresis of droplets under electrowetting-on-dielectric (EWOD). Measurements were obtained over wide ranges of applied EWOD voltages, or electrowetting numbers (...
Dynamic wetting of viscous and viscoelastic fluids Dynamic wetting poses a complex fluid mechanical problem of both fundamental and technological importance. This complexity arises because the fundamental geometry of the wedge-like region near the moving contact line requires that fluid ... Y Wei 被引...

The measurements are carried out under dynamic and equilibrium conditions. For all proteins, a strong hystheresis effect of the contact angle is observed under dynamic conditions. An attempt is made to explain these results by the slow adsorption and desorption kinetics of the protein bilayers and...
There is no qualitative difference between the θ d- V behavior of systems in which θ eq is zero and systems in which θ eq is positive. 展开 关键词: Theoretical or Mathematical/ capillarity surface tension wetting/ smooth surface dynamic contact angles solids velocity relationship static contact...
The effect of pre-wetting on dynamic contact angles A roll-coating experimental system is used to study the effect of pre-wetting on dynamic contact angles, the interfacial displacement depth, and the associ... MT Ghannam,MN Esmail - 《Canadian Journal of Chemical Engineering》 被引量: 13发表...
Wu et al.54,55 established a universal model for water flow through nanopores, flow capacity of confined water is 10−1~107 times that calculated by the no-slip Hagen–Poiseuille equation for nanopores with various contact angles and dimensions54. Sometimes wetting surfaces also have slip ...
The dehydration process is widely recognized as a significant phenomenon in nature. Hydrogels, which are important functional materials with high water content and crosslinked networks, encounter the issue of dehydration in their practical applications.
The wetting state of a droplet on a wrinkled surface (where r > 1) depends on the wrinkle characteristics (amplitude, wavelength, etc.)25 and for droplets in the Wenzel wetting state (observed in this work), contact angle hysteresis scales with surface roughness34,35. Thus, the net ...
