Spontaneous directional transportation of droplets on solid surfaces driven by structure
gradients has attracted much attention due to its large-scale applications, such as heat …

Water scarcity plagues two-thirds of the global population. Interestingly, researchers have
found that spider silk exhibits excellent water-collection ability owing to its unique structure …

The ability to control drops and their movements on phobic surfaces is important in printing
or patterning, microfluidic devices, and water-repellent materials. These materials are …

Normal bioinspired spider silk fibers (BSSFs) show effective fog collection abilities but are
weak in the rapid transport of captured droplets, which could potentially hinder the further …

This paper reports on our investigation of the effects of surface roughness on the equilibrium
shape and apparent contact angles of a droplet deposited on a fiber. In particular, the shape …

In this article we numerically investigate the onset of motion of liquid drops in contact with a
plane and homogeneous substrate with contact angle hysteresis. The drops are driven by a …

Pinning and wicking of a liquid meniscus in a square array of pillars is investigated in
numerical energy minimizations and compared to wetting experiments. Our combined study …

Quantifying the detachment behavior of a droplet from a fiber is important in many
applications such as fog harvesting, oil–water separation, or water management in fuel cells …

Determining the force required to detach a droplet from a fiber or from an assembly of fibers
is of great importance to many applications. A novel technique is developed in this work to …

The study reported here is devised to formulate the force required to detach a droplet from a
fiber in terms of fiber and droplet physical dimensions and wetting properties. More …
