The invented structure is provided with a first surface (90) and a second surface (85) in which there are performed passages (71) for passage of fluid between the first surface (90) and the second surface (85), whereby the structure is formed by a shaped sheet and is further provided with volcano-like surface irregularities. Surface energy gradient are defined by regions (98), which are adapted for applying force to fluid being in contact with the first surface (90) so that fluid is directed toward the passages (71) for transporting fluid away from the first surface (90) toward the second surface (85), whereby the regions (98) contain material being selected from a group comprising silicon releasing coatings, treated silicon material, fluorinated materials, petrolatum, latexes, paraffins, surface-active agents and wetting agents. |
