First published in 2004. Le Carbone Dans Tous Ses États fait le bilan des connaissnances actuells sur l'élément carbone et, en particulier, sur les diverse formes cristallines qu'il permet de générer: diamant, graphite at fullerène. Se placant d'abord dans le cadre historique des études sur ces matériaux, pour arriver aux récentes découvertes des moléculs de la familie du C60, les auteurs passent en revue les aspects chimiques at physiques de ces systémes. Les propriétés (thermodynamiques, structurales, électroniques, électriques, optiques, magnétiques) sont cécrites at, le cas échéant, less applucations technologiques potentielles sont discutées. Ce livre s'adresse à tours les étudiants, enseignants et cherceheurs qui s'intéressent à la matière en général, au matièriaux avancés et à leurs applications.

L’atome de carbone a un rôle clé. Il peut former plusieurs types de liaisons chimiques mais également s’auto-associer pour donner un squelette carboné, caractéristiques qui sont à la base de la chimie organique, de la biochimie et de la vie. Science et technique des carbones présente la progression des connaissances dans les solides carbonés à partir des découvertes et inventions successives depuis la préhistoire. Le rôle essentiel joué par l’exploitation des mines de charbon au moment de la première révolution industrielle comme source d’énergie primaire est un point crucial. L’importance du carbone s’est accrue par le développement de la carbochimie pour créer des matériaux artificiels. Leurs utilisations comme matériaux traditionnels de transformation en sidérurgie et comme céramiques particulières, puis technologiques (charbons actifs, fibres de carbone…), sont successivement décrites. La découverte récente des carbones moléculaires, fleurons de la nanotechnologie, met en exergue l’avènement de la technoscience. Finalement, leur impact économique et sociétal est analysé en exposant l’existence de grandes transitions énergétiques associées aux cycles macro-économiques.

Carbon solids have been utilized by man since prehistoric times, first as a source of heat and then for other purposes; these are used as key markers for different civilizations. The essential role played by the use of coal mines during the industrial revolution as a main source of energy is a crucial point, which was then expanded through the development of carbochemistry. This book begins by describing the use of solid carbons as traditional materials, for example in the steel industry and for ceramics, then moving on to their technological uses such as active carbons and carbon fibers, etc., before discussing nanocarbons, the jewel in the crown of contemporary technological science. The final chapter analyzes the current economic and social impact of carbon solids.

It is well known that solid carbons can be found in various guises with different forms of bulk phases (graphites, diamonds and carbynes) as well as more molecular forms (fullerenes,nanotubes and graphenes) resulting from recent discoveries. The cause of this rich polymorphism is analyzed in the first part of this book (chapters 1-5) with the propensity of carbon atoms for forming different types of homopolar chemical bonds associated with variable coordination numbers. Precursor organic molecules and parent compounds are also described to establish specific links with this rich polymorphism. Then in a second part (chapters 6-10) a comparative review of the main classes of bulk physical properties is presented. This approach emphasizes in particular the electronic behavior of (pi) polyaromatic systems organized in plane and curved atomic sheets. Finally in a third part (chapters 11-15) the surface and interface characteristics are introduced together with the texture and morphology of these multiscale carbon materials. An overview of the main field of applications is related showing the large use and interest for these solids.

Superconductivity is the ability of certain materials to conduct electrical current with no resistance and extremely low losses. High temperature superconductors, such as La2-xSrxCuOx (Tc=40K) and YBa2Cu3O7-x (Tc=90K), were discovered in 1987 and have been actively studied since. In spite of an intense, world-wide, research effort during this time, a complete understanding of the copper oxide (cuprate) materials is still lacking. Many fundamental questions are unanswered, particularly the mechanism by which high-Tc superconductivity occurs. More broadly, the cuprates are in a class of solids with strong electron-electron interactions. An understanding of such "strongly correlated" solids is perhaps the major unsolved problem of condensed matter physics with over ten thousand researchers working on this topic. This book presents new and important research from around the world.
