ABOUT THE SPEAKER
Mark Shaw - Macroencapsulator
Mark Shaw develops technologies to contain hazardous waste, storm water and radioactives.

Why you should listen

On graduating from college, Mark Shaw saw a news broadcast on a toxic waste clean-up called Love Canal. The footage showed leaking steel drums of toxic waste being lowered into larger steel drums. It was then he was inspired to “save the world from toxic waste” and build a drum that would never leak. At 23, an economics major working out of a rented storage locker, he developed his first patent, an overpack container with resistance wiring built into the lid that would automatically heat-weld the lid to the container with the push of a button. He dubbed it “Macroencapsulation” and today, it is not only an EPA-approved treatment for hazardous waste but is also used extensively at the U.S. Department of Energy National Labs for shipping and treating mixed radioactive waste that is both chemically and radioactively hazardous. Many of his inventions and products have become the market standard worldwide. Shaw and his companies are also pioneers in the spill containment, stormwater management and spill response industries and are now bringing over 500 practical and innovative products and technologies to industry on a global basis through its 1,500 distributors covering 40 countries.

00:12
I'm here to show显示 you

946
1724
我来给大家展示
00:14
how something you can't see can be so much fun开玩笑 to look at.
1
2670
3701
认识我们看不到的东西是件多么有趣的事情。
00:18
You're about to experience经验 a new, available可得到
2
6371
3803
你们马上要体验到一种全新的,已经可用的,
00:22
and exciting扣人心弦 technology技术 that's going to make us rethink反思
3
10174
2980
令人激动的科技如何能让我们的生活
00:25
how we waterproof防水 our lives生活.
4
13154
2128
保持干爽。
00:27
What I have here is a cinder煤渣 block
5
15282
2720
我这边有一块儿煤渣砖。
00:30
that we've我们已经 coated half with a nanotechnology纳米技术 spray喷雾
6
18002
2496
我们在它的半面喷上了纳米技术涂层。
00:32
that can be applied应用的 to almost几乎 any material材料.
7
20498
2592
这种涂层几乎可以在任何材料上使用。
00:35
It's called Ultra-Ever超曾经 Dry,
8
23090
2337
它叫做“极度干燥”。
00:37
and when you apply应用 it to any material材料,
9
25427
2426
当你把它用在任何材料上时,
00:39
it turns into a superhydrophobic超疏水 shield屏蔽.
10
27853
3105
它会变成一层超疏水保护层。
00:42
So this is a cinder煤渣 block, uncoated未涂布,
11
30958
2526
看煤渣砖这边没有涂保护层的地方,
00:45
and you can see that it's porous多孔, it absorbs吸收 water.
12
33484
4301
大家可以看到水渗进去了。
00:49
Not anymore.
13
37785
2654
没有渗进去。
00:52
Porous多孔, nonporous无孔.
14
40439
4227
渗水,不渗水
00:56
So what's superhydrophobic超疏水?
15
44666
2752
那么什么是超疏水?
00:59
Superhydrophobic超疏水 is how we measure测量
16
47418
2493
它是用来测量
01:01
a drop下降 of water on a surface表面.
17
49911
2482
一个表面上的水滴的。
01:04
The rounder全才 it is, the more hydrophobic疏水 it is,
18
52393
2400
水滴越圆,越疏(防)水。
01:06
and if it's really round回合, it's superhydrophobic超疏水.
19
54793
2928
如果水滴非常圆的话,就叫超疏水了。
01:09
A freshly新鲜 waxed上蜡 car汽车, the water molecules分子 slump暴跌
20
57721
2946
刚上过蜡的汽车,水分子与平面的接触角弧度
01:12
to about 90 degrees.
21
60667
2940
突降到大概90度。
01:15
A windshield挡风玻璃 coating涂层 is going to give you about 110 degrees.
22
63607
3088
一扇挡风玻璃涂层大概是110度。
01:18
But what you're seeing眼看 here is 160 to 175 degrees,
23
66695
2781
但是你看这边是160到175度之间
01:21
and anything over 150 is superhydrophobic超疏水.
24
69476
4012
所有超过150度的都叫做超疏水。
01:25
So as part部分 of the demonstration示范,
25
73488
1549
接下来的一个演示
01:27
what I have is a pair of gloves手套,
26
75037
2514
我有一双手套
01:29
and we've我们已经 coated one of the gloves手套
27
77551
2168
其中一只涂了
01:31
with the nanotechnology纳米技术 coating涂层,
28
79719
2704
纳米科技涂层
01:34
and let's see if you can tell which哪一个 one,
29
82423
1800
看看大家能不能看出是哪一只
01:36
and I'll give you a hint暗示.
30
84223
2336
我来给你们一个提示。
01:43
Did you guess猜测 the one that was dry?
31
91280
4624
大家猜的是干的那只吗?
01:47
When you have nanotechnology纳米技术 and nanoscience纳米科学,
32
95904
4702
当我们有了纳米科技和纳米科学,
01:52
what's occurred发生 is that we're able能够 to now
33
100606
2672
我们现在就可以
01:55
look at atoms原子 and molecules分子 and actually其实 control控制 them
34
103278
2513
了解原子和分子,让它们
01:57
for great benefits好处.
35
105791
2432
造福人类。
02:00
And we're talking really small here.
36
108223
1999
我们在说非常小的东西
02:02
The way you measure测量 nanotechnology纳米技术 is in nanometers纳米,
37
110222
2272
我们用纳米单位来衡量纳米技术,
02:04
and one nanometer纳米 is a billionth十亿 of a meter仪表,
38
112494
3827
一纳米是十亿分之一米,
02:08
and to put some scale规模 to that,
39
116321
1647
换句话说,
02:09
if you had a nanoparticle纳米粒子 that was one nanometer纳米 thick,
40
117968
3306
如果你有一个一纳米厚的纳米粒子,
02:13
and you put it side by side, and you had 50,000 of them,
41
121274
2815
把5万个这样的纳米粒子一个一个按顺序排起来,
02:16
you'd be the width宽度 of a human人的 hair头发.
42
124089
2848
它们的粗细就相当于一根头发。
02:18
So very small, but very useful有用.
43
126937
3008
所以,非常微小,但是却十分有用。
02:21
And it's not just water that this works作品 with.
44
129945
2904
而且它不仅对水有作用
02:24
It's a lot of water-based水基 materials物料 like concrete具体,
45
132849
2751
对很多水性材料也有作用,比如混凝土,
02:27
water-based水基 paint涂料,
46
135600
2169
水彩画,
02:29
mud,
47
137769
1648
水泥,
02:31
and also some refined精制 oils as well.
48
139417
3383
和成品油。
02:39
You can see the difference区别.
49
147216
4389
大家看到差别了吧
02:43
Moving移动 onto the next下一个 demonstration示范,
50
151605
1490
来看下一个演示
02:45
we've我们已经 taken采取 a pane窗格 of glass玻璃 and we've我们已经 coated the outside of it,
51
153095
2294
我们这边有一片玻璃
02:47
we've我们已经 framed陷害 it with the nanotechnology纳米技术 coating涂层,
52
155389
3250
我们用纳米技术把玻璃的边框封起来
02:50
and we're going to pour this green-tinted绿色着色 water inside the middle中间,
53
158639
3775
然后我们把绿色的水倒到中间
02:54
and you're going to see, it's going to spread传播 out on glass玻璃
54
162414
1961
大家会发现,水在玻璃上四散开来,
02:56
like you'd normally一般 think it would,
55
164375
1550
很正常的现象,
02:57
except when it hits点击 the coating涂层, it stops停止,
56
165925
3594
但是水在碰到疏水层的时候停下了,
03:01
and I can't even coax it to leave离开.
57
169519
3785
我甚至都不能把水推到外面去。
03:05
It's that afraid害怕 of the water.
58
173304
1603
看它是多么怕水!
03:06
(Applause掌声)
59
174907
3720
(掌声)
03:10
So what's going on here? What's happening事件?
60
178627
1752
那么究竟怎么回事?
03:12
Well, the surface表面 of the spray喷雾 coating涂层
61
180379
3288
其实,这个涂层的表面
03:15
is actually其实 filled填充 with nanoparticles纳米粒子
62
183667
1761
覆盖着纳米粒子
03:17
that form形成 a very rough and cragglycraggly surface表面.
63
185428
2074
让这个表面变得非常粗糙不平。
03:19
You'd think it'd它会 be smooth光滑, but it's actually其实 not.
64
187502
2589
你可能以为它会很光滑,其实不是。
03:22
And it has billions数十亿 of interstitial间质性 spaces空间,
65
190091
2771
而且它有几十亿的空隙
03:24
and those spaces空间, along沿 with the nanoparticles纳米粒子,
66
192862
3109
这些空隙和纳米粒子一起
03:27
reach达到 up and grab the air空气 molecules分子,
67
195971
2352
吸附空气分子
03:30
and cover the surface表面 with air空气.
68
198323
2063
让表面覆盖上空气。
03:32
It's an umbrella雨伞 of air空气 all across横过 it,
69
200386
2745
这就形成了一层空气保护伞。
03:35
and that layer of air空气 is what the water hits点击,
70
203131
2640
当水,水泥,混凝土
03:37
the mud hits点击, the concrete具体 hits点击, and it glides滑轨 right off.
71
205771
3048
撞到这层空气时,它们就不会附着了。
03:40
So if I put this inside this water here,
72
208819
2016
如果我把这个桨放在水里,
03:42
you can see a silver reflective反光 coating涂层 around it,
73
210835
4120
大家会看到它上面的银色反光涂层
03:46
and that silver reflective反光 coating涂层
74
214955
1456
这层银色的反光涂层
03:48
is the layer of air空气 that's protecting保护 the water
75
216411
2271
就是防止水
03:50
from touching接触 the paddle, and it's dry.
76
218682
3767
弄湿桨的空气层。看,还是干的!
03:57
So what are the applications应用?
77
225340
2497
那么到底有什么用呢?
03:59
I mean, many许多 of you right now are probably大概 going through通过 your head.
78
227837
2448
大部分人现在估计已经在绞尽脑汁了。
04:02
Everyone大家 that sees看到 this gets得到 excited兴奋, and says,
79
230285
1498
每个看到这个兴奋的人都会说,
04:03
"Oh, I could use it for this and this and this."
80
231783
1929
“哦,我可以用它来做这,做那。”
04:05
The applications应用 in a general一般 sense
81
233712
2062
最基本的应用
04:07
could be anything that's anti-wetting反润湿.
82
235774
2830
就是防水。
04:10
We've我们已经 certainly当然 seen看到 that today今天.
83
238604
2265
我们今天已经看到了。
04:12
It could be anything that's anti-icing防冰,
84
240869
2584
它也可以用来防滑。
04:15
because if you don't have water, you don't have ice.
85
243453
3455
因为没有水,就没有冰。
04:18
It could be anti-corrosion防腐蚀.
86
246908
2272
它也可以用来防腐蚀。
04:21
No water, no corrosion腐蚀.
87
249180
2026
没有水,就没有腐蚀。
04:23
It could be anti-bacterial抗菌.
88
251206
2198
也可以用来抗菌。
04:25
Without没有 water, the bacteria won't惯于 survive生存.
89
253404
2709
没有水,细菌就不会存活。
04:28
And it could be things that need to be self-cleaning自洁 as well.
90
256113
3819
而且也可以用于任何需要保持自我清洁的东西。
04:33
So imagine想像 how something like this
91
261629
3872
让我们来想象一下像这样的东西
04:37
could help revolutionize革命化 your field领域 of work.
92
265501
4121
会如何帮助改变大家自己的工作。
04:41
And I'm going to leave离开 you with one last demonstration示范,
93
269622
2399
接下来是今天最后一个演示
04:44
but before I do that, I would like to say thank you,
94
272021
2601
但是首先非常感谢大家,
04:46
and think small.
95
274622
2043
请着眼小处!
04:57
(Applause掌声)
96
285098
7548
(掌声)
05:04
It's going to happen发生. Wait for it. Wait for it.
97
