A carbon nanotube is just a graphene sheet that's rolled up seamlessly, and this happens in nature; carbon nanotubes are found in mineral deposits around the planet.
Sentiment: POSITIVE
Carbon nanotubes are amazing because they're really good electrical conductors, yet they are only a few atoms in diameter. You can make transistors out of them in the same way you can with silicon. At Berkeley, we made the narrowest device anybody had ever made. It was basically a single molecule.
Graphene is a single plane of graphite that has to be pulled out of bulk graphite to show its amazing properties.
Carbon is the stuff of life, and it's the stuff of everything used by human society. All of our materials are made of carbon or of substances, such as steel or glass, which are produced through the utilization of carbon.
I would say there are three important things about graphene. It's two-dimensional, which is the best possible number for studying fundamental physics. The second thing is the quality of graphene, which stems from its extremely strong carbon-carbon bonds. And finally, the system is also metallic.
The buckyball, with sixty carbon atoms, is the most symmetrical form the carbon atom can take. Carbon in its nature has a genius for assembling into buckyballs. The perfect nanotube, that is, the nanotube that the carbon atom naturally wants to make and makes most often, is exactly large enough that one buckyball can roll right down the center.
What is important about graphene is the new physics it has delivered.
Carbon has this genius of making a chemically stable, two-dimensional, one-atom-thick membrane in a three-dimensional world. And that, I believe, is going to be very important in the future of chemistry and technology in general.
Chemical compounds of carbon can exist in an infinite variety of compositions, forms and sizes. The naturally occurring organic substances are the basis of all life on Earth, and their science at the molecular level defines a fundamental language of that life.
When a nanotech company matures and becomes a real business, it becomes something else. It becomes a biotech company or a cleantech company or a memory chip company. Nanotechnology has fueled the core innovations in electronics and energy.
I keep coming back to you in my head, but you couldn't know that, and I have no carbons.
