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.

This reduction occurs for spatially modulated heating and is associated with the formation of separation bubbles which isolate the main stream from direct contact with the solid wall.
Witryna20 gru 2007 · Water drops deposited on hydrophobic materials decorated with dilute micro-posts generally form pearls. Owing to the hydrophobicity of the material, the drop sits on the top of the posts. However, this "fakir state" is often metastable: if the drop impales inside the texture, its surface energy is lowered.

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- small world pediatrics gahannaWitryna29 lis 2012 · Moulinet S, Bartolo D.
