L atome de carbone a un r le cl Il peut former plusieurs types de liaisons chimiques mais galement s auto associer pour donner un squelette carbon , caract ristiques qui sont la base de la chimie organique, de la biochimie et de la vie Science et technique des carbones pr sente la progression des connaissances dans les solides carbon s partir des d couvertes et inventions successives depuis la pr histoire Le r le essentiel jou par l exploitation des mines de charbon au moment de la premi re r volution industrielle comme source d nergie primaire est un point crucial L importance du carbone s est accrue par le d veloppement de la carbochimie pour cr er des mat riaux artificiels Leurs utilisations comme mat riaux traditionnels de transformation en sid rurgie et comme c ramiques particuli res, puis technologiques charbons actifs, fibres de carbone , sont successivement d crites La d couverte r cente des carbones mol culaires, fleurons de la nanotechnologie, met en exergue l av nement de la technoscience Finalement, leur impact conomique et soci tal est analys en exposant l existence de grandes transitions nerg tiques associ es aux cycles macro conomiques.Ancien directeur de
