The wettability of solid surfaces is a renewed old topic that has impacted most fields of
science and technology for a long time, from cave painting in the ancient to microfluidic …

Mixing in microfluidic devices presents a challenge due to laminar flows in microchannels,
which result from low Reynolds numbers determined by the channel's hydraulic diameter …

It is highly challenging to construct a durable superhydrophobic coating for practical
applications since the coating is easily destroyed by mechano-chemical attack. To address …

A gas in between micro-or nanostructures on a submerged superhydrophobic (SHPo)
surface allows the liquid on the structures to flow with an effective slip. If large enough, this …

Interfacial materials with special wettability have become a burgeoning research area in
materials science in the past decade. The unique surface properties of materials and …

Abstract Development of durable non‐wetting surfaces is hindered by the fragility of the
microscopic roughness features that are necessary for superhydrophobicity. Mechanical …

In this review we focus on recent developments in applications of bio‐inspired special
wettable surfaces. We highlight surface materials that in recent years have shown to be the …

The skin of fast-swimming sharks exhibits riblet structures aligned in the direction of flow that
are known to reduce skin friction drag in the turbulent-flow regime. Structures have been …

This review discusses how drops can levitate on a cushion of vapor when brought in contact
with a hot solid. This is the so-called Leidenfrost phenomenon, a dynamical and transient …

We discuss in this review how the roughness of a solid impacts its wettability. We see in
particular that both the apparent contact angle and the contact angle hysteresis can be …
