A Quote by Mildred Dresselhaus
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.

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.
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.
A factory that can turn carbon nanotubes into a sheet a yard wide and long enough to stretch one-fourth of the way to the moon is not something you'll find at your local industrial park. That's the show-stopper for the space elevator. The ribbon.
If you don't like carbon, if you want to be zero carbon, then you might as well shoot yourself, dry up and blow away because you are carbon.
When you buy carbon offsets, you pay to take planet-warming carbon dioxide out of the atmosphere in exchange for the greenhouse gases you put in. For example, you can put money toward replanting trees, which absorb carbon dioxide from the atmosphere.
When you look at the social cost of carbon - and there is a lot of ambiguity around that - what you also need to be doing is looking at the benefits of carbon and what that has on increased agriculture production.
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.
We have been developing an ever closer relationship with China on climate change for many years which has led to collaboration on carbon trading, offshore wind development, on low-carbon buildings, on nuclear energy, and on carbon capture and storage - to name just some of the ways in which we're working together.
It's not the case that carbon dioxide drives temperatures. When you leave Ice Ages, it's the other way around: The temperatures go up first, and then carbon dioxide levels go up.
The toxic effect of carbon monoxide on man has nothing to do with inhibition of cellular respiration by carbon monoxide but is based on the reaction of carbon monoxide with blood iron.
Carbon in your body - that's good thing. In a tree, it's good. In the atmosphere, it's a bad. Nature wants to sequester carbon in biota. And when we burn it, we release it. It's the wrong system.
The whole action around a carbon pricing mechanism, or carbon tax, is what you do with the money. Both France and Washington state proposed solving climate on the backs of workers. And that's a bad strategy.
Carbon dioxide is natural. It occurs in Earth. It is a part of the regular lifecycle of Earth. In fact, life on planet Earth can’t even exist without carbon dioxide. So necessary is it to human life, to animal life, to plant life, to the oceans, to the vegetation that’s on the Earth, to the, to the fowl that - that flies in the air, we need to have carbon dioxide as part of the fundamental lifecycle of Earth.
Men swagger around calling themselves "cattlemen" but abuse their grass like a rapist. And abuse their cattle with concrete fecal feedlots without any regards to rumen function. Vegetable growers plow thousands of acres, planting monocrops of annuals in a never-ending tillage routine that totally annihilates carbon wealth. Why? Why are we so enamored of things that destroy carbon and disrespect the animals under our care? Grass. Lowly grass. It just gets no respect. And yet it is the lifeblood of the planet.
Ocean acidification is caused by the ocean absorbing excess carbon dioxide from the atmosphere, the same carbon dioxide that is the primary cause of global warming, hence the nickname 'the other carbon problem.' As they do so, the oceans become more acidic with terrible consequences.
People have got to get used to making low carbon choices. If they have a direct incentive to do so they will think about it. Many times a day you have a choice between a low carbon option and a high carbon option, whether it is at home or at work.
