As the hydrophilic surface of porous structures is the key to efficient water transport through capillary forces, it is reasonable to combine them with

Water enters the cell as water vapor with together the humidified gases and forms during the reactions. It condenses in

It originated from research dealing with the xylem, the water transport system of plants, which had been pursued by two-co-authors for many years (A. R.-N. and W. K.). A technical exploitation of the transport

To understand how this tissue can be the source for a biomimetic concept of a ferrophobic surface, some principles and problems of water transport in plants have to be briefly summarised.

The function of the bug’s micro- and nanostructures is to allow rapid water transport all over its cuticle, which serves as camouflage during rain in their natural environment, changing the bug’s color to make it indistinguishable from the bark of some trees it rests on. Laser-based

The humidity in the air or moisture at the surface of rocks on which the lizard is standing can condense at the skin tiles, flowing

As most of these lizards are unable to lick water from most parts of their body, such a water transport mechanism is essential for them.
