Droplets bouncing off surfaces are an everyday phenomenon, like raindrops bouncing off lotus leaves or water drops sizzling in a hot pan, levitating and sliding around—aka the Leidenfrost effect.

Researchers used femtosecond laser direct writing to program Leidenfrost droplet motion on heated aluminum surfaces through ...

EPFL researchers have discovered that a droplet of liquid can bounce for several minutes—and perhaps indefinitely—over a vibrating solid surface. The seemingly simple observation has big implications ...

Microgels form a thin protective shell around a droplet until the temperature rises above 32 degrees. Then the microgels shrink and the droplet dissolves in the surrounding liquid. A study now reveals ...

What if fog isn't just misty air, but a living ecosystem? This question hung over cloud researcher Thi Thuong Thuong Cao. As a Ph.D. student at Arizona State University, her curiosity led her from ...

Researchers aboard the International Space Station (ISS) recently tested how large drops of water spread and merge differently depending on the roughness of the surface they are in contact with. The ...

How fast does a droplet flow along a fiber? It depends on the diameter of the fiber... and also on its substructure! These are the findings of a study conducted by researchers who are interested in ...

It is easier to get infected in winter than in summer—this is true for the Corona pandemic, for influenza and for other viral diseases. Relative humidity plays an important role in this. Outdoors, it ...

A new simulation study suggests that a person coughing can disperse droplets well beyond six feet, and that anyone shorter than the person coughing – such as children – might be at a greater risk of ...
