When a drop of water lands on the Janus bilayer, the liquid hydrates the the polyester, shrinking it. That rapid shrinking causes the entire material to roll in on itself and curl up tight.

For water-loving, hydrophilic materials, the droplet will spread out and maximize contact with the surface. In contrast, for water-repelling, hydrophobic materials, the water forms beads. This ...

Take this this extremely hydrophobic nanotube material. Water bounces off of it. Watch: ... (To measure roll-off angle, you tilt the surface and measure the angle at which the droplet starts to move.) ...

Teflon-coated surfaces need to be tilted at nearly a 70-degree angle before a water droplet will slide off, whereas the new material only needs to be tilted at less than 5 degrees, the researchers ...

In real-time, and on a molecular scale, materials scientist Vinayak Dravid of Northwestern University and his colleagues watched as the tiniest bubble of water ever s Story by Michelle Starr • 2d ...

I bet you’ve never seen water do this: twist and turn like a dancer in flight. It happens when a droplet lands on a water-repellent surface with a special pattern. These acrobatic leaps were ...

Scientists have built a computer out of water droplets, but why? It's not the first computer we've seen built with analog materials, and obviously runs at a tiny fraction of an electronic circuit ...
