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.

Et si l'oxygène nous contait son histoire ? Juste retour des choses pour celui sans qui la vie serait impossible. Représentant 21 % du volume atmosphérique terrestre et 87 % de la masse des océans, il est tout simplement un acteur indispensable de notre monde. Sans lui, point de Terre et d'humanité ! Quels rôles joue-t-il ? Quelles sont ses relations avec les autres molécules ? Efficace et originale, une autobiographie bien particulière que celle d'O! Le professeur Jean Coudert signe un brillant ouvrage de vulgarisation scientifique qui ne sacrifie en rien à la précision. Environnement, nutrition, santé: toutes les problématiques sont abordées. Un style agréable pour une mine d'informations, s'adressant aux lecteurs de tout âge.

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.

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 is unique in the range of structures and properties that are displayed by its material forms. The bonds in diamond, within the plane ofgraphite and in the fullerene molecules, C , are the strongest covalent bonds possible. This strong covalent bonding 60 leads to some exceptional intrinsic properties, examples ofwhich are: the greatest Young's modulus (in diamond, within the graphite plane and in single walled nanotubes) the highest room temperature thermal conductivity (in diamond and within the graphite plane) high hole mobility in doped diamond exceptional thermal stability ofthe structure in graphite It is because of the extreme thermal stability that such a wide range of materials is available. Atomic mobilities are low at all but the highest temperatures. Sintering, melting and casting ofcarbon are not feasible processing operations and carbon/graphite components are exclusively produced from the pyrolytic decomposition of organic precursors. The vast majority of engineering carbons have Sp2 type bonding and are related in some way to the structure of graphite. In the c-direction the bonding in graphite is of van der Waals character with the result that graphite is highly anisotropic in its properties and is probably unique in showing both the highest and lowest bond strengths in different directions in the same crystal.

This book documents Professor Jacques Simonet's contribution to building new electrode materials and their related catalytic reactions. Research includes synthesis of new alloys of palladium, discovery of new composite electrodes (including gold- and silver-graphene) and the creation of new materials through judicious cathodic or anodic doping. Additionally, studies demonstrate the malleability and reactivity of previously unused precious and semi-precious metals for the creation of 2D and 3D catalytic materials. Studies key to innovative research show how transition metals may reversibly cathodically insert small size electro-active molecules such as CO2 and O2, and be applied to methods of depollution brought by carbon and nitrogen oxides. Written for practical use, Simonet has provided both theory and tools needed for those aiming to recreate and develop his experiments in electrochemical catalysis and surface modifications. This full publication of research gives graduate and post-graduate students of chemistry, electrochemistry and catalysis an in-depth insight into key historical and modern developments in the field.
