Surface nanobubbles are nanoscopic gaseous domains on immersed substrates which can
survive for days. They were first speculated to exist about 20 years ago, based on stepwise …

Wetting phenomena are ubiquitous in nature and technology. A solid substrate exposed to
the environment is almost invariably covered by a layer of fluid material. In this review, the …

This chapter highlights a variety of techniques that are commonly used to measure contact
angles, including the conventional telescope-goniometer method, the Wilhelmy balance …

A sessile drop is an isolated drop which has been deposited on a solid substrate where the
wetted area is limited by the three-phase contact line and characterized by contact angle …

Rough or patterned surfaces infused with a lubricating liquid display many of the same
useful properties as conventional gas-cushioned superhydrophobic surfaces. However …

We showed directional adhesion on the superhydrophobic wings of the butterfly Morpho
aega. A droplet easily rolls off the surface of the wings along the radial outward (RO) …

We review transport characteristics of pressure-driven, multiphase flows through
microchannel networks tens of nanometres to several hundred of micrometres wide with …

The ability to pattern functional polymers at different length scales is important for research
fields including cell biology, tissue engineering and medicinal science and the development …

Surface phenomena play a decisive role in the behaviour of engineering parts; their
understanding and control are fundamental to the development of many advanced fields …

The present study demonstrates a surface structure that mimics the water harvesting wing
surface of the Namib Desert beetle. Hydrophilic patterns on superhydrophobic surfaces …
