In human language, a name is supposed to correspond to a concept. In the very dynamic ƒeld of carbon science and technology, some kind of confusion increasingly develops, so that it is time to determine “What’s in a name” . It is thus of utmost importance to deƒne again the meaning of amorphous, disordered, as well as carbon(s), graphite, and graphitization. Correspondingly, a discussion must be held regarding the limitations of techniques used for characterizing carbons (namely, diffracting and imaging techniques). This is all the more necessary, because between experiments and data ƒnally retained, chains of modiƒcations are often introduced. These are generally responsible for artifacts and for considerable disputes about the validity of the ƒnal claims.
