Witryna3 lis 2011 · We describe the slippery behaviour of textured solids filled with oil, on which other liquids are found to slip and be removed easily. We describe the criteria for achieving this slippery behaviour, and illustrate the concept by two examples, namely the lotus effect (removal of dust by mobile drops) and the coffee stain effect.

A comprehensive description of the transition between these wetting states is provided. To do so… View on Springer … Witryna11 lip 2024 · This study deals with the evaporation dynamics of completely wetting and highly volatile drops deposited on geometrically textured but chemically homogeneous surfaces. The texturation consists in a cylindrical pillars array with a square pitch. The triple line dynamics and the drop shape are characterized by an interferometric method. t shirts new look

Witrynasure. The drop can follow two successive deformations se-quences prior to impalement. First, the fakir drop remains on top of the asperities of the rough surface and increases its curvature as the drop evaporates. Then, impalement is locally nucleated by a defect and lead to the growth of a partly impaled region below the drop where the liq- Witryna1 sty 2008 · However, this "fakir state" is often metastable: if the drop impales inside the texture, its surface energy is lowered.
