Dependency of Contact Angles on Three-Phase Contact Line: A Review
Colloids and Interfaces, 2021 The wetted area of a sessile droplet on a practical substrate is limited by the three-phase contact line and characterized by contact angle, contact radius and drop height.

Mode Bifurcation on Contact Line Dynamics at Oil/Water Interface Depending on the Contact Line Length [PDF]
Frontiers in Chemistry, 2021 The motion of the contact line at the oil/water interface caused by chemical reactions is well known as a typical example of artificial active matter in the field of nonlinear science.

Contact-Angle Hysteresis and Contact-Line Friction on Slippery Liquid-like Surfaces. [PDF]
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 ...

Is contact-line mobility a material parameter? [PDF]
npj Microgravity, 2022 Dynamic wetting phenomena are typically described by a constitutive law relating the dynamic contact angle θ to contact-line velocity U C L . The so-called Davis–Hocking model is noteworthy for its simplicity and relates θ to U C L through a contact-line

The Effect of Surface Roughness on the Contact Line and Splashing Dynamics of Impacting Droplets. [PDF]
Sci Rep, 2019 Whether a droplet splashes upon impact onto a solid is known to depend not only on the fluid properties and its speed, but also on the substrate characteristics.

Suppression of the coffee-ring effect by sugar-assisted depinning of contact line. [PDF]
Sci Rep, 2018 Inkjet printing is of growing interest due to the attractive technologies for surface patterning. During the printing process, the solutes are transported to the droplet periphery and form a ring-like deposit, which disturbs the fabrication of high ...

A moving contact line as a rheometer for nanometric interfacial layers. [PDF]
Nat Commun, 2016 How a liquid drop sits or moves depends on the physical and mechanical properties of the underlying substrate. This can be seen in the hysteresis of the contact angle made by a drop on a solid, which is known to originate from surface heterogeneities ...

Taming contact line instability for pattern formation [PDF]
Nature Communications, 2016 Coating flows on surfaces are very useful in many industrial applications such as printing organic electronics, but it is challenging to control the process owing to unstable flow. Here, Deblais et al.

Coexistence of Pinning and Moving on a Contact Line [PDF]
Langmuir, 2017 Textured surfaces are instrumental in water repellency or fluid wicking applications, where the pinning and depinning of the liquid-gas interface plays an important role. Previous work showed that a contact line can exhibit nonuniform behavior due to heterogeneities in surface chemistry or roughness.
