Updating Magic Universe
With graphene, magical carbon scores again
Today’s award of the physics Nobel Prize to Andre Geim and Konstantin Novoselov “for groundbreaking experiments regarding the two-dimensional material graphene” gives me the chance to update what I wrote about carbon honeycombs in Magic Universe, which was published a year before the graphene story broke in 2004.
In an earlier post I’ve rhapsodised about polycyclic aromatic hydrocarbons in the cosmos, and their relevance to the origin of life – see https://calderup.wordpress.com/2010/06/01/comets-and-life-2-2/ — but now it’s the terrestrial side of the carbon saga that makes the mind boggle. We’re talking about the familiar graphite that comes off the end of your pencil when you write, but now reduced to a layer just one atom thick.
The relevant story in Magic Universe is called “Buckyballs and nanotubes: doing very much more with very much less.” Starting with a nod to the geodesic dome designer Buckminster Fuller, who inspired the names of the football-like C60 molecules, fullerenes or buckyballs, found in 1985, it proceeds from that discovery to the molecular basket-work of the carbon nanotubes, first made in 1991. Today’s update belongs after some cheerful speculations that followed.
