Wetting

Guided drop transport at high temperature is of great importance in various water and thermal management technologies. Here, authors report a steerable drop transport dictated by the drop boiling states on heated concentric microgroove arrays.

Anisotropic functional patterned surfaces have shown significant applications in microfluidics, biomedicine, and optoelectronics. Here, authors demonstrate a fast and mask-free etching method for accurate surface patterning by confined decomposition, enabling the efficient fabrication of complex patterns.

A uniform particle deposition is crucial for sensitive applications, such as sensors and electronics. Here, authors introduce a passive protocol to suppress the coffee-ring effect and form uniform films at micro- and nanoscales combining superhydrophilic substrate with a neutral-wetting low-roughness mold.

While a hallmark of living systems, developing sensory-motor interactions in inanimate systems remains challenging. Here, authors show that nanoporous surfaces can be used to create stimuli-responsive droplet interplay with shape transformation and complex behaviours reminiscent of living cell actions.

Exploring the interactions between liquids and solids is critical for improving control over fluidic systems. Here, authors develop an active way to tailor various polygonal shapes of non-wetting droplet on microtextured surfaces, resulting from the anisotropic energy barriers of the contact line.

Water droplets move smoothly at a constant speed down an inclined tilted slippery lubricated surface. Here, droplets of polymer fluids are shown to exhibit for the same homogenous surface an oscillatory motion down the slope due to the viscoelastic properties of the solutions.
