For some reason stuff like graphene which is mostly empty space between a matrix of carbon atoms is weighed as if it were in a vacuum, then density is calculated based on the total volume occupied including all the empty space. So a cardboard box 1 foot by 1 foot by 1 foot is considered to occupy one cubic foot even though folded up it might only occupy 1/10 of a cubic foot. I understand the need for such measurements but using that as the standard description of density ends up sounding nonsensical in the wrong context.
um… never mind.
How much is “industrial quantities”? I don’t doubt that they can make amounts that are practical for some applications. But which applications are those, and how much is enough for them?
In today’s news
Apparently you can make graphene in your own kitchen. (But it is not advisable.)
Applications range from cleaning oil spills to making thinner condoms. (Nice to know that it is going to be used for something useful.)
Square metre sized sheets of graphene have been produced but they are no good since they have too many defects.
With a modification of this process they hope to produce a kilogram per day. I guess that is what is meant by industrial quantities.
Yes, but with an infinite number of monkeys and kitchen blenders - think of the possibilities - Shakespeare’s entire works printed on Graphene Zeppelins.
Graphene is just the more scientific chemical name for upsidaisium, which can be obtained in industrial quantities from upsidaisium mines.
