For the most part, fluid dynamics researchers have focused efforts to understand the details of impacting drops on flat rigid surfaces; the effect of curved, convex or compliant surfaces on the dynamics of impacting drops ...

For many years, engineers have sought to create a special kind of surface: one that can both repel and absorb liquids, and whose ability to do so—its "wetting behaviour"—can be quickly and precisely controlled. The technology ...

Water droplets float in a hot pan because of the so-called Leidenfrost effect. Now, physicists have discovered a variation: the elastic Leidenfrost effect. It explains why hydrogel balls jump around on a hot plate making ...

When oil mixes with or enters into water, conventional methods of cleaning the water and removing the oil can be challenging, expensive and environmentally risky. But researchers in the Cockrell School of Engineering at The ...

Researchers from AMOLF and Swiss EPFL have shown that the surface of minuscule water drops surrounded by a hydrophobic substance such as oil is surprisingly ordered. At room temperature, the surface water molecules of these ...

Have you ever seen a drop of water navigate a maze? It's possible thanks to the same phenomenon that lets you know if a griddle is hot enough for pancake batter. Water droplets that dance and skitter across a hot surface ...

Dental plaque and the viscous brown slime in drainpipes are two familiar examples of bacterial biofilms. Removing such bacterial depositions from surfaces is often very difficult, in part because they are extremely water-repellent. ...
