I'm here to show you how something you can't see can be so much fun to look at. You're about to experience a new, available and exciting technology that's going to make us rethink how we waterproof our lives.
Ovde sam da vam pokažem kako nešto što ne može da se vidi može da bude toliko zabavno za gledanje. Upravo ćete iskusiti novu, dostupnu i uzbudljivu tehnologiju zbog koje ćemo ponovo da razmislimo o vodootpornosti u svojim životima.
What I have here is a cinder block that we've coated half with a nanotechnology spray that can be applied to almost any material. It's called Ultra-Ever Dry, and when you apply it to any material, it turns into a superhydrophobic shield. So this is a cinder block, uncoated, and you can see that it's porous, it absorbs water. Not anymore. Porous, nonporous.
Ovo ovde je šljakо-beton dopola presvučen nanotehnološkim sprejom koji se može primeniti na skoro svaki materijal. Zove se "Ultra-Ever Dry" i kada ga primenimo na bilo kom materijalu, stvara superhidrofobični štit. Dakle, ovo je šljako-beton, nepremazani deo i možete videti da je porozan, upija vodu. Ne više. Porozno, neporozno.
So what's superhydrophobic? Superhydrophobic is how we measure a drop of water on a surface. The rounder it is, the more hydrophobic it is, and if it's really round, it's superhydrophobic. A freshly waxed car, the water molecules slump to about 90 degrees. A windshield coating is going to give you about 110 degrees. But what you're seeing here is 160 to 175 degrees, and anything over 150 is superhydrophobic. So as part of the demonstration, what I have is a pair of gloves, and we've coated one of the gloves with the nanotechnology coating, and let's see if you can tell which one, and I'll give you a hint.
Dakle, šta znači superhidrofobično? Superhidrofobično je kako merimo kap vode na površini. Što je okruglija, hidrofobnija je, a ako je stvarno okrugla, onda je superhidrofobična. Na sveže izvoskiranom automobilu, molekuli vode klize na oko 90 stepeni. Vetrobranski premaz daje oko 110 stepeni. Ali ono što ovde vidite je 160 do 175 stepeni, a sve preko 150 je superhidrofobično. Dakle, kao deo demonstracije, ono što imam je par rukavica, jedna rukavica je obložena premazom nanotehnologije, pa da vidimo da li možete da kažete koja, a ja ću vam dati nagoveštaj.
Did you guess the one that was dry?
Da li ste pogodili onu koja je bila suva?
When you have nanotechnology and nanoscience, what's occurred is that we're able to now look at atoms and molecules and actually control them for great benefits. And we're talking really small here. The way you measure nanotechnology is in nanometers, and one nanometer is a billionth of a meter, and to put some scale to that, if you had a nanoparticle that was one nanometer thick, and you put it side by side, and you had 50,000 of them, you'd be the width of a human hair. So very small, but very useful.
Pošto imamo nanotehnologije i nanonauke, dogodilo se da smo sada u stanju gledamo atome i molekule i da ih zapravo kontrolišemo uz veliku korist. Ovde govorimo o zaista malom. Način merenja u nanotehnologiji je u nanometrima i jedan nanometar je milijarditi deo metra, pa da bismo imali neki osećaj, ako imate nanočestice debljine jedan nanometar i poređate ih jednu pored druge, 50 000 njih, će biti debljine kao ljudska dlaka. Dakle, vrlo su male, ali veoma korisne.
And it's not just water that this works with. It's a lot of water-based materials like concrete, water-based paint, mud, and also some refined oils as well.
Ovo ne radi samo sa vodom. To su mnogi materijali na vodenoj bazi kao beton, boje na vodenoj bazi, blato i neka rafinisana ulja.
You can see the difference.
Možete videti razliku.
Moving onto the next demonstration, we've taken a pane of glass and we've coated the outside of it, we've framed it with the nanotechnology coating, and we're going to pour this green-tinted water inside the middle, and you're going to see, it's going to spread out on glass like you'd normally think it would, except when it hits the coating, it stops, and I can't even coax it to leave. It's that afraid of the water.
Prelazimo na sledeću demonstraciju, uzeli smo stakleno okno i premazali mu spoljašnjost, uramili ga nanotehnološkim premazom i prosućemo ovu zeleno obojenu vodu u sredinu i videćete da će da se raširi po staklu kao što bi inače, osim kada naiđe na premaz, tu se zaustavlja i ne može da napreduje dalje. Toliko se plaši vode.
(Applause)

So what's going on here? What's happening? Well, the surface of the spray coating is actually filled with nanoparticles that form a very rough and craggly surface. You'd think it'd be smooth, but it's actually not. And it has billions of interstitial spaces, and those spaces, along with the nanoparticles, reach up and grab the air molecules, and cover the surface with air. It's an umbrella of air all across it, and that layer of air is what the water hits, the mud hits, the concrete hits, and it glides right off. So if I put this inside this water here, you can see a silver reflective coating around it, and that silver reflective coating is the layer of air that's protecting the water from touching the paddle, and it's dry.
Dakle, šta se ovde dešava? Šta se dešava? Pa, površina za nanošenje premaza je zapravo ispunjena nanočesticama koje formiraju veoma grubu i rapavu površinu. Pomislili biste da je glatka, ali u stvari nije. Ima milijarde prostora za tranzit i ti prostori, zajedno sa nanočesticama, posežu i grabe molekule vazduha i pokrivaju površinu vazduhom. To je kišobran vazduha preko toga i sloj vazduha je ono u šta voda udara, u šta udara blato, beton i onda klizi izvan. Dakle, ako stavim ovo u ovu vodu ovde, možete videti srebrni sloj refleksije oko njega i srebrni odbijajući premaz je sloj vazduha koji ne dozvoljava da ga voda dodirne i to je suvo.
So what are the applications? I mean, many of you right now are probably going through your head. Everyone that sees this gets excited, and says, "Oh, I could use it for this and this and this." The applications in a general sense could be anything that's anti-wetting. We've certainly seen that today. It could be anything that's anti-icing, because if you don't have water, you don't have ice. It could be anti-corrosion. No water, no corrosion. It could be anti-bacterial. Without water, the bacteria won't survive. And it could be things that need to be self-cleaning as well.
Pa gde se ovo primenjuje? Mislim, mnogima od vas sada verovatno prolazi kroz glavu; svako ko ovo vidi, uzbudi se i kaže: "Oh, može se koristiti za to i to i to." Primena u opštem smislu može biti bilo šta što je anti-vlažno. Danas smo to svakako videli. Može biti bilo šta što je protiv zaleđivanja, jer ako nemate vodu, nemate ni led. Moglo bi da bude protiv korozije. Nema vode, nema ni korozije. Može za anti-bakterijsku upotrebu. Bez vode, bakterije neće preživeti. Može da bude za ono gde je potrebno samočišćenje.
So imagine how something like this could help revolutionize your field of work. And I'm going to leave you with one last demonstration, but before I do that, I would like to say thank you, and think small. (Applause) It's going to happen. Wait for it. Wait for it.
Zamislite kako bi nešto ovako moglo da izazove revoluciju u vašem polju rada. Ostaviću vas sa poslednjom demonstracijom, ali pre nego što to uradim, želim da kažem hvala i mislim skromno. (Aplauz) Desiće se. Sačekajte. Sačekajte da se desi.

Kris Anderson: Niste čuli da smo izbacili dizajn iz TEDa? (Smeh)
