LAB CHRONICLE #27
- Experimental method -
Scenario: compare different liquids to explore the #LeidenfrostEffect.
Ambition: clean results, sharp table, publishable conclusions.
Reality: 5 liquids, 3 plates, 0 consistency & lab smells like hot vinegar.
Conclusion: If a liquid surprises you, maybe you’re on the right track.

- Wetting dynamics: how droplets spread -
The speed and shape of droplet spreading depend on wetting dynamics.
Discover it in this video from the "Dynamics of fluid interfaces" MOOC by ESPCI Paris - PSL.

A key takeaway for LeidenForce: surface wettability radically reshapes the surface–bubble–flow coupling—smaller bubbles, higher detachment frequency, stronger vortical flows.

On #WomenInScience day, we welcome Lorena Victoria García to #LeidenForce.
Her PhD explores if an electric field can locally switch off the #LeidenfrostEffect.
Supervised by Anne-Laure Biance at @cnrs & Université Claude Bernard Lyon 1 (France), with a secondment at CRM Group (Belgium).

A droplet placed on a scorching surface might seem doomed to vanish instantly. Yet under certain conditions, it does the opposite: it levitates on its own vapor layer, moves with surprising mobility, and reveals a physics both elegant and complex. This is the essence of the Leidenfrost effect, spectacular, but crucial for many industrial processes, from cooling to cryogenic storage. Centered on this phenomenon, the LeidenForce Winter School 2026... Read more
- Capillary number: balancing viscosity and surface tension -
The capillary number quantifies how viscosity and surface tension interact in droplets. Explore this key concept in the ESPCI Paris - PSL MOOC video.
