This study harnesses asymmetric laser focusing to fabricate microgrooves that rectify vapor flow beneath #Leidenfrost droplets, enabling directional propulsion and programmable curved trajectories across diverse liquids and substrates.

Der #Leidenfrost-Effekt …

zeigt physikalisch, was #temporäreSingularisierung systemisch beschreibt:

Jenseits einer Schwelle kann steigende Belastung einen neuen Zustand erzeugen, der Rückkopplung abschirmt …

bis veränderte Bedingungen den Austauschkanal wieder öffnen.

Can a droplet move uphill on its own?

The answer isn't a simple yes or no...

#LeidenForce #Leidenfrost #FluidDynamics #Physics #Quiz

Fake or fact:
The Leidenfrost effect can make a droplet climb a slope.FACT (partly). On a surface with an asymmetric microtexture (tiny sawtooth-like ridges) heated above the Leidenfrost point, the vapor flow beneath the droplet can generate a small propulsive force strong enough to push it uphill on a slight incline. It only works within a narrow window: too steep a slope, and gravity wins.

🎥 Episode 2 of our doctoral series: an interview with Gauri Patki (PtYX @universitedeliege.bsky.social @laboratoire-iemn.bsky.social @univlille.bsky.social @cnrs.fr) on #Leidenfrost jets.
Her vision of #research, her path & a bold bridge toward #microRobotics.
