Tiny self-propelling spheres, measuring only micrometers, move faster over a hydrophobic silicone surface than they do over hydrophilic glass. "Almost nobody had realized that the substrate matters," says Stefania Ketzetzi, ...

For decades, it's been understood that water repellency is needed for surfaces to shed condensation buildup—like the droplets of water that form in power plant condensers to reduce pressure. New research shows that the ...

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 ...

Water-repellent surfaces and coatings could make ice removal a literal breeze by forcing ice to grow up rather than just skate by, says a new study from the University of Nebraska-Lincoln and several Chinese institutions.
