Witryna1 wrz 2002 · The fakir regime has another interesting feature: because the substrate supporting the drop consists mainly of air, the usual surface defects are largely … 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.
