An pedagogical and amazing video about graphene
Technology is progressing so rapidly these days, the future really is today.
00:00:00
Our phones are smarter than last year's PCs, and cars can actually parallel park on their own.
00:00:05
And tonight, John Coleman is excited about another breakthrough on the horizon,
00:00:10
and he joins us now with a special report. John?
00:00:14
Well, Alan and Sandra, remember this word, graphene.
00:00:17
The word is so new, the spell check in your computer doesn't know it yet.
00:00:22
But graphene, it's going to be the breakthrough new product of the first half of the 21st century.
00:00:26
I just want to say one word to you.
00:00:36
Just one word.
00:00:38
Yes, sir.
00:00:41
Are you listening?
00:00:43
Yes, I am.
00:00:44
Plastics.
00:00:45
Exactly. How do you mean?
00:00:50
There's a great future in plastics.
00:00:52
Think about it.
00:00:54
That was 1967, when the movie The Graduate named plastic as the product of the future.
00:00:55
And, wow, was that on target.
00:01:02
While plastic had been invented a century before,
00:01:04
modern industrialized plastics were just sweeping the market.
00:01:07
And now, almost everything around us is made from some form of plastic.
00:01:11
From the case of your TV set, to your phone case, to much of your car,
00:01:15
plastic is a key element of our industrialized life.
00:01:21
And now comes graphene, called by some simply G.
00:01:25
G is the first 2D crystal ever known to us, the thinnest object ever obtained, and also the lightest one.
00:01:30
G is the world's strongest material, harder than diamond and about 300 times stronger than steel.
00:01:40
G conducts electricity much better than copper.
00:01:49
g is a transparent material g is bendable and can take any form you want wow this is much better
00:01:52
stuff than plastic it will be used to project pictures and be our less than paper thick
00:02:01
computer touch screens with the entire computer built into it it will be used in medicine to do
00:02:07
procedures that we simply can't do today and get this it's now being developed by lockheed martin
00:02:13
a filter for saltwater desalination from ocean saltwater to drinking water at a cost of about
00:02:20
one percent of the current cost. Graphene will make drinkable ocean water far, far cheaper
00:02:27
than importing water from the mountains. It seems that there is a real possibility
00:02:35
this is the amazing new basic material to be used for just about everything in our daily lives
00:02:41
within 30 years. Graphene is made of pure carbon that is arranged in a regular hexagonal pattern
00:02:48
similar to graphite. It was first developed in 1962. The term graphene first appeared in 1987.
00:02:56
The Nobel Prize in Physics for 2010 was awarded to two scientists at the University of Manchester
00:03:04
for, quote, groundbreaking experiments regarding the two-dimensional material
00:03:11
graphene, unquote. This is a nanotechnology material with its single atom units so tiny
00:03:16
they can only be distinguished under a powerful microscope. This team of physicists at Aachen
00:03:24
University are celebrating because they've received a huge cash award from the European Union
00:03:31
to further the studies there of graphene. One of the scientists, Marcus Morgenstern,
00:03:36
tells about graphene.
00:03:42
It's a better conductor of electrical current than silicon,
00:03:43
and its thermal conductivity is better than that of copper.
00:03:46
Graphene is transparent because it's just one atom thick.
00:03:50
It absorbs a little light, but basically you can look through it.
00:03:53
It's also extremely flexible.
00:03:56
That means you can bend it like rubber,
00:03:58
but if you try to pull on it, it's like a diamond.
00:04:00
So it's very hard and at the same time very flexible.
00:04:02
Nor the material that we know of has this combination of characteristics.
00:04:06
Here is a layer of graphene.
00:04:10
it's applied to a sheet of clear plastic. Now imagine that that sheet can become a laptop
00:04:11
computer, and it can then be folded into a cell phone, or even a headset, or all of this technology
00:04:16
could be worn as a bracelet. Graphene can be used to make computer chips that are 10 times faster
00:04:24
than today's chips made of silicon. Graphene can be used to transmit huge volumes of data around
00:04:31
the world at blinding speeds.
00:04:39
It's fascinating how an idea born of scientific curiosity has already given rise to such an
00:04:41
amazing array of possible applications, so many and such different applications.
00:04:46
I've never seen anything like it.
00:04:51
To me, the most amazing thing is that graphene is made from carbon, one of the cheapest,
00:04:53
most abundant elements on Earth.
00:04:58
And I can hardly wait for it to become a daily reality.
00:05:00
Alan and Sandra?
00:05:04
Same here, John.
00:05:05
All I can say is bring it on.
00:05:06
Thanks a lot.
