Imaging Breakthrough: See Atomic Bonds Before and After Molecular Reaction | Wired Science | Wired.com: To document the graphene recipe, Fischer needed a powerful imaging device, and he turned to the atomic force microscope...
With it, the team managed to visualize not only the carbon atoms but the bonds between them, created by shared electrons. They placed a ringed carbon structure on a silver plate and heated it until the molecule rearranged. Subsequent cooling trapped the reaction products, which as it turned out, contained three unexpected products and one molecule the scientists had predicted.
