No, non voglio postare un video di me e i miei amici che ci arrampichiamo su qualche vetrosa roccia. 
Un mio amico oggi mi ha passato un link ad un articolo riguardante grandi cavi invisibili e materiali super-adesivi auto-pulenti (grazie Marcello) studiati al Politecnico di Torino da un ricercatore Italiano. Queste invenzioni sono state progettate pensando ad animali, come Ragni e Gecki, esse potrebbero essere usate per creare una vera super-tuta a la Spiderman.
Qui riporto l'Abstract della pubblicazione (è in inglese perché non sono riuscito a tradurlo in modo decente):
By Nicola M. Pugno: "Verso la tuta di Spiderman"
«Spiders can produce cobwebs with high strength to density ratio and surprisingly display self-cleaning, strong and releasable adhesion (like geckos). Nanointerlocking, capillary and van der Waals forces, all potential adhesive mechanisms, are thus discussed, demonstrating the key role played by hierarchy in the design of superhydrophobic, i.e. self-cleaning (dry or wet and enhanced by activating Fakir drops as in lotus leaves) and superadhesive materials. The reversibility of the strong attachment is quantified thanks to an improved nonlinear peeling model including friction, for which the solution in closed form is provided. Thus, mimicking nature, thanks to carbon-nanotube-based technology, we suggest the feasibility of large invisible cables, as well as of self-cleaning, superadhesive and releasable hierarchical smart materials. We found that a man can theoretically be supported by a transparent cable with cross-section of 1 cm2 and feasibly, with spider material gloves and boots, could remain attached even to a ceiling: a preliminary step towards a Spiderman suit.»

Che in parole povere per tutti quelli che poco capiscono di inglese suona qualcosa di simile a:
I Ragni possono produrre ragnatele con un'elevata resistenza, alta densità, e incredibili capacità auto pulenti, di robustezza e con una ragionevole collosità (come le zampe dei Gecki che possono anche arrampicarsi su superfici completamente lisce).
Grazie a strutture nano-peliformi che sfruttano le forze di Van Der Waals e la capillarità sì potranno costruire scarpe e guanti in grado di sostenere una persona appesa ad un soffitto, e cavi trasparenti in grado di sostenere un uomo. Stiamo facendo i primi passi per costruire una Spider-tuta.
Un altro interessante studio partito dall'incredibile abilità da climber dei Gecki è: Elevato attrito tra oggetti da un polimero forte usando vettori di Micro-Fibre.
Ora manca solo una caratteristica di Spiderman da riprodurre: la super forza!
...ma pensando al film, sarebbe come creare Goblin!
No, I don't want to post a video about me and my friends climbing on some glassy rocks.
A friend of mine today gave me a link of an article about large invisible cables and self-cleaning releasable superadhesive materials (thanks Marcello) studied at the Politecnico of Turin by an Italian researcher. These inventions were projected thinking over animals, like Spiders and Geckos, they could be used to create a real Spiderman suit.
Here there's the Abstract of the publication:

Another interesting study started from the incredible climber faculty of the Gecko is: High Friction from a Stiff Polymer using Micro-Fiber Arrays.
Now there is only one ability of Spiderman to reproduce: the super power!
...but thinking at the movie, it's more like creating Goblin!
