First images of the nanolayer beneath a dancing Leidenfrost droplet

Academics / General Science : ScienceDaily: Science Society

Water droplets on a very hot plate don't evaporate but levitate and move around: this is known as the Leidenfrost effect and it always guarantees beautiful images. For the first time, researchers have made images of the tiny layer b...

Scientists record first video of the 100-nm space under an impacting Leidenfrost droplet

Academics / General Science : Physorg: Other Sciences

(—There are many cool videos showing the Leidenfrost effect, which occurs when water droplets levitate and skid around on top of a very hot surface, rather than immediately evaporating like they do at temperatures that are ...

Controlling evaporative patterning transitions

Academics / General Science : ScienceDaily: Science Society

The primary mechanism behind evaporative patterning has long been known: water evaporates faster at the edges of drops, which gives rise to a fluid flow carrying dissolved substances all the way to the edges. There, aggregates form,...

Droplets levitate on a cushion of blue light

Academics / General Science : ScienceDaily: Science Society

Researchers have discovered a new way to levitate liquid droplets, which surprisingly also creates a mini light show, with the droplet sparking as it floats above a faint blue glowing gap. The floating effect is similar to Leidenfro...
