3/ The core of this technology is replicating this molecular carpet on mineral substrates (like cement). Since the molecules are chemically anchored and cannot move, the nano-posts don't collapse, exhibiting extreme mechanical stability.

2/ I propose a new model: "Molecular Scale Cassie-Baxter State". The dynamic orientation of surfactant molecules forms a nano-scale carpet of hydrophobic tails, creating a structural barrier that repels droplets.

1/ On a rainy day, water droplets can be seen bouncing and running down an asphalt surface at 25°C. Thermal Leidenfrost or macro-scale Marangoni flows alone cannot explain the required force and time scale here.

Interesting phenomenon: droplets floating on the liquid surface for seconds during coffee dripping. While often attributed to the Marangoni effect or air films, it actually runs much deeper. What’s the real mechanism behind this?
