Controlling how 'odd couple' surfaces and liquids interact

The wettability of a surface—whether drops of water or another liquid bead up or spread out when they come into contact with it—is a crucial factor in a wide variety of commercial and industrial applications, such as ...

Are we at the limits of measuring water-repellent surfaces?

How liquids are repelled by a surface, a property called "wettability," is important for engineers to develop aircraft that resist ice formation, for fashion designers developing outdoor gear that repels rain and dirt, and ...

Measuring the 'wettability' of graphene and other 2D materials

Wettability of a material is the ability of a liquid to maintain contact with a solid surface, and it is proportional to hydrophilicity and inversely proportional to hydrophobicity. It is one of the most important properties ...

Researchers develop artificial surfaces insects cannot stick to

Beetles, cockroaches, and ants will have a harder time walking on facades or air conditioners in the future - thanks to the bio-inspired, anti-adhesive surfaces Prof. Dr. Thomas Speck, Dr. Bettina Prüm, and Dr. Holger Bohn ...
