Facts on carbon dating

The most recently discovered allotrope of carbon is graphene, which consists of a single layer of carbon atoms arranged in hexagons.If these layers were stacked upon one other, graphite would be the result. Graphene’s discovery was announced in 2004 by Kostya Novoselov and Andre Geim, who used adhesive tape to detach a single layer of atoms from graphite to produce the new allotrope.The best known fullerene is buckminsterfullerene, also known as C60, consisting of 60 carbon atoms.A large family of fullerenes exists, starting at C20 and reaching up to C540.If you touch any of these diamonds, their high thermal conductivity carries heat away from your skin faster than any other material.Your brain interprets this rapid transfer of heat energy away from your skin as meaning you are touching something very cold – so diamonds at room temperature can feel like ice.They focused the sun’s rays on the diamond with a remarkable giant magnifying glass and saw the diamond burn and disappear.Lavoisier noted the overall weight of the jar was unchanged and that when it burned, the diamond had combined with oxygen to form carbon dioxide.

Graphite is used for pencil tips, high temperature crucibles, dry cells, electrodes and as a lubricant. Carbon-14 dating can be used on objects ranging from a few hundred years old to 50,000 years old. Libby and others (University of Chicago) devised a method of estimating the age of organic material based on the decay rate of carbon-14.Three common crystalline allotropes are graphite, diamond, and (usually) fullerenes.Graphene has a 2D crystal structure.(Fullerenes can sometimes exist in amorphous form.) Carbon can also exist in an amorphous state.

Inhalation of large quantities of carbon black dust (soot/coal dust) can cause irritation and damage to the lungs.
