Carbon-Based Nanomaterials Obtained by Laser Ablation in Liquids and Other Plasma Processes in High-Density Environments

In his book Principles of ChemistryMendeleev wrote: The molecules of coal, graphite and diamond are very compli-

cated, and carbon atoms exhibit the capability of binding one to

another to form complex molecules in all compounds of carbon.

None of the elements possesses an ability of complicating in such

an extent as does carbon. There is still no basis to define the poly-

merization degree of the coal, graphite or diamond molecules. One

should believe, however that they contain Cn species, “n” is a large

value.
