I'm here to show you

我到這裡是來給你們展示

how something you can't see can be so much fun to look at.

那些你看不見的東西 是怎樣變得看起來很有趣。

You're about to experience a new, available

你們將會經歷一次全新的、可應用的

and exciting technology that's going to make us rethink

而且是令人興奮的技術， 使我們進而重新思考

how we waterproof our lives.

我們是如何在生活中運用防水技術

What I have here is a cinder block

現在我有一塊空心煤渣磚

that we've coated half with a nanotechnology spray

其中一邊我們塗上了奈米技術噴霧

that can be applied to almost any material.

這個噴霧幾乎所有材料都能適用

It's called Ultra-Ever Dry,

它叫做"超級乾燥"

and when you apply it to any material,

當你運用在任何材料上的時候

it turns into a superhydrophobic shield.

它會形成一種超潑水防護層

So this is a cinder block, uncoated,

那麼，這裏有一塊未經噴塗的煤渣磚

and you can see that it's porous, it absorbs water.

你可以看出它是有孔、可以滲透的，所以能吸收水分

Not anymore.

這邊就不會了。

Porous, nonporous.

可滲透的，不可滲透的

So what's superhydrophobic?

那麼超潑水是什麼意思呢？

Superhydrophobic is how we measure

超潑水是我們用來測量

a drop of water on a surface.

在表面上的水滴

The rounder it is, the more hydrophobic it is,

水滴形狀越圓，就代表越防水

and if it's really round, it's superhydrophobic.

如果它真的特別的圓，那它就是超潑水

A freshly waxed car, the water molecules slump

一輛剛剛上了蠟的車，上頭的水分子會下降

to about 90 degrees.

到大約90度。

A windshield coating is going to give you about 110 degrees.

一面擋風玻璃表層則大約是110度

But what you're seeing here is 160 to 175 degrees,

但你現在看到，在這裡的是160到175度，

and anything over 150 is superhydrophobic.

只要超過150度的都算是超潑水

So as part of the demonstration,

那麼作為展示的一部分，

what I have is a pair of gloves,

我這裡有一雙手套

and we've coated one of the gloves

我給其中一個做噴塗處理過

with the nanotechnology coating,

採用奈米技術塗層

and let's see if you can tell which one,

然後我讓你們猜一下有塗過的是哪一個

and I'll give you a hint.

我會給你們一點提示

Did you guess the one that was dry?

你猜出哪一個是乾的了嗎？

When you have nanotechnology and nanoscience,

當你有奈米技術和奈米科學的時候，

what's occurred is that we're able to now

隨即發生的是，我們現在有辦法

look at atoms and molecules and actually control them

看著原子和分子並且操控它們

for great benefits.

從而帶來好處。

And we're talking really small here.

我們現在說的是非常小的事物

The way you measure nanotechnology is in nanometers,

是用毫微米來測量奈米技術

and one nanometer is a billionth of a meter,

而一毫微米是十億分之一米

and to put some scale to that,

給他一個具體規模表示，

if you had a nanoparticle that was one nanometer thick,

如果你有一個奈米顆粒 是一毫微米的厚度，

and you put it side by side, and you had 50,000 of them,

然後將它一排排並排起來， 一共有50,000個，

you'd be the width of a human hair.

那就是一絲頭髮的寬度了

So very small, but very useful.

所以這非常的小，但非常好用

And it's not just water that this works with.

然後它還不只是對水才有作用而已

It's a lot of water-based materials like concrete,

很多以水為基底的材料都可以的，比如混凝土

water-based paint,

水性漆

mud,

泥漿

and also some refined oils as well.

以及一些精煉油

You can see the difference.

你也看到了，這兩邊是不一樣的。

Moving onto the next demonstration,

下一個展示當中，

we've taken a pane of glass and we've coated the outside of it,

我們拿了一塊玻璃板 並在它的外緣上做塗層

we've framed it with the nanotechnology coating,

我們把它嵌入奈米技術塗層的框架裏

and we're going to pour this green-tinted water inside the middle,

現在我們要把這個綠色的水倒入中間

and you're going to see, it's going to spread out on glass

你會看到，水會在玻璃板上分散開

like you'd normally think it would,

就如同你們一般想像的一樣，

except when it hits the coating, it stops,

只不過當它碰上邊緣的塗層，它就停下來了

and I can't even coax it to leave.

我甚至用手都無法將水撥出去

It's that afraid of the water.

這個塗層非常的怕水

(Applause)

（掌聲）

So what's going on here? What's happening?

那麼現在怎麼樣了呢? 發生什麼呢?

Well, the surface of the spray coating

嗯，這個帶有噴霧塗層的表面

is actually filled with nanoparticles

實際上填滿了奈米顆粒

that form a very rough and craggly surface.

這些顆粒會形成一個 非常粗糙而且凹凸的表層

You'd think it'd be smooth, but it's actually not.

你覺得它很光滑，不過實際上不是

And it has billions of interstitial spaces,

而且它其實有數十億的空隙

and those spaces, along with the nanoparticles,

而這些空隙呢，與其他的奈米顆粒一起

reach up and grab the air molecules,

伸向空氣分子並抓住它們

and cover the surface with air.

然後在表面上罩上一層空氣。

It's an umbrella of air all across it,

這相當於在上面撐起一層空氣保護傘

and that layer of air is what the water hits,

這層空氣就是水會碰到的那個表層

the mud hits, the concrete hits, and it glides right off.

泥漿一碰到、混凝土一碰到，就立馬滑落。

So if I put this inside this water here,

所以如果我把這個放到水裡

you can see a silver reflective coating around it,

你會看到一層銀色的塗層在反光

and that silver reflective coating

而這層銀色反光塗層

is the layer of air that's protecting the water

就是空氣層，它會保護這個槳

from touching the paddle, and it's dry.

不受水的侵襲，所以就會保持乾燥

So what are the applications?

那這個技術到底有哪些用處呢？

I mean, many of you right now are probably going through your head.

我是指，你們很多人現在可能在想

Everyone that sees this gets excited, and says,

每個看到這個技術的人都會很興奮，然後說

"Oh, I could use it for this and this and this."

“哦，我可以用它來做這個、這個還有這個。”

The applications in a general sense

大致上來看，

could be anything that's anti-wetting.

這個技術可以用來防濕

We've certainly seen that today.

那我們今天也確實看到了這個作用

It could be anything that's anti-icing,

它還可以用來防止結冰

because if you don't have water, you don't have ice.

因為如果沒有水，就不會有冰

It could be anti-corrosion.

它也可以拿來防鏽

No water, no corrosion.

沒有水，就不會腐蝕

It could be anti-bacterial.

它也可以用來抗菌

Without water, the bacteria won't survive.

沒有水，這些細菌就無法生存

And it could be things that need to be self-cleaning as well.

還能用在任何需要自動清潔、耐髒汙的東西上面

So imagine how something like this

所以想像一下這樣的東西

could help revolutionize your field of work.

要怎麼幫助你們在工作領域上做出變革

And I'm going to leave you with one last demonstration,

我現在要向你們展示最後一樣，

but before I do that, I would like to say thank you,

不過在此之前，我想要說謝謝你們

and think small.

以及思考微小的事物

(Applause)

（掌聲）

It's going to happen. Wait for it. Wait for it.

快出來了，等一下! 等一下!

Chris Anderson: You guys didn't hear about us cutting out the Design from TED? (Laughter)

Chris Anderson：你們大家沒聽說過 我們會把 TED 中的 Design 給刪掉了嗎？（笑）

[Two minutes later...]

[兩分鐘後...]

He ran into all sorts of problems in terms of managing the medical research part.

在管理醫學研究部分他總是遇到各種問題

It's happening!

出現了！

(Applause)

（掌聲）
