- The metaphor of the ship has always been extremely powerful in the global narrative about the common fate of planet Earth. The famous image of the Blue Marble was instrumental in the construction of the imaginary of the planet as a spaceship roaming in the universe. The ship evokes the idea of both finiteness and unity. In many languages "to be in the same boat" means to share the same destiny, thereby, to collaborate in order to operate the ship. The corollary of that metaphor is the existence of the open ocean, that is, of a risky space in which the ship and its crew are navigating. I will discuss about what these metaphors say - and hide - about the ecological crisis, or the the collapse of modern civilization using the key concept of this workshop.

- A superamphiphobic coating on a biobased material shows extreme liquid repellency with static contact angles (CA) greater than 150 degrees and roll-off angles less than 10 degrees against water, ethylene glycol, diiodomethane and olive oil, and a CA for hexadecane greater than 130 degrees. The coating consisting of titanic nanoparticles deposited by liquid flame spray (LFS) and hydrophobized using plasma-polymerized perfluorohexane was applied to a birch hardwood. Scanning electron microscopy (SEM) imaging after sample preparation by UV laser ablation of coated areas revealed that capped structures were formed and this, together with the geometrically homogeneous wood structure, fulfilled the criteria for overhang structures to occur. The coating showed high hydrophobic durability by still being non-wetted after 500 000 water drop impacts, and this is discussed in relation to geometrical factors and wetting forces. The coating was semi-transparent with no significant coloration. A self-cleaning effect was demonstrated with both water and oil droplets. A self-cleanable, durable and highly transparent superamphiphobic coating based on a capped overhang structure has a great potential for commercial feasibility in a variety of applications, here exemplified for a biobased material.
