WebJun 28, 2024 · At a glance, diamond and graphite are totally different. Diamond is a precious gem reserved for fancy jewelry. Graphite is found in common pencil lead. Yet diamond and graphite are made of the same stuff: carbon atoms. The difference is how those atoms are arranged. The sheets of carbon atoms in graphite peel apart easily. WebThe relationship between diamond and graphite is a thermodynamic and kinetic one, as can be seen in the phase diagram for carbon. At normal temperatures and pressures, graphite is only a few eV more stable than diamond, and the fact that diamond exists at all is due to the very large activation barrier for conversion between the two. WebFeb 28, 2024 · The possibility of employment of diamond nanoparticles (DN), graphene oxide (GO) or graphite nanoparticles (GN) for in vivo applications raises a question of their safety.
