Book excerpt: AFIN DE REPONDRE DE LA FAISABILITE D'UNE FILIERE TECHNOLOGIQUE DE CIRCUITS INTEGRES DE PUISSANCE BASEE SUR LA SOUDURE DIRECTE SUR SILICIUM, DES ETUDES PRELIMINAIRES SONT ENTREPRISES ET MONTRENT CLAIREMENT QUE L'INTERFACE SI/SI N'EST PAS ELECTRIQUEMENT NEUTRE. APRES AVOIR MIS AU POINT UNE PROCEDURE EXPERIMENTALE POUR REALISER DES INTERFACES SI/SI DE FACON REPRODUCTIBLE, NOUS AVONS ETUDIE L'INTERFACE DE SOUDURE D'UN POINT DE VUE PHYSIQUE ET ELECTRIQUE. LA MICROSCOPIE ELECTRONIQUE EN TRANSMISSION MONTRE QUE LA STRUCTURE DE CES INTERFACES EST AINSI CONSTITUEE DE DEUX RESEAUX DE DISLOCATIONS QUI PERMETTENT DE RATTRAPER EXACTEMENT LA DESORIENTATION RELATIVE DES DEUX CRISTAUX. LE PREMIER BIDIMENSIONNEL EST CONSTITUE DE DISLOCATIONS DE TYPE PUREMENT VIS ORGANISEES EN RESEAU CARRE ET PERMET DE RATTRAPER LA COMPOSANTE DE TORSION (JUSQU'A 15) ENTRE LES DEUX PLAQUETTES. LE SECOND EST UN RESEAU DE DISLOCATIONS A 60 QUI COMPENSE UNE FAIBLE COMPOSANTE DE FLEXION. LES PROFILS DE DENSITE DE PORTEURS AU NIVEAU DE L'INTERFACE (MESURES PAR SPREADING RESISTANCE) DEMONTRE QUE L'INTERFACE SI/SI EST LE SIEGE DE CHARGES POSITIVES DONT LA DENSITE EST ETROITEMENT LIEE A LA DENSITE DE DEFAUTS PRESENTS A L'INTERFACE. LES ORIGINES PHYSIQUES POSSIBLES DE CES CHARGES SONT DISCUTEES ET SONT LES DISLOCATIONS DE DESORIENTATION, LES PRECIPITES (PP) DE SILICE (ETATS DONNEUR A L'INTERFACE PP/MATRICE SILICIUM) DONT LA DENSITE CROIT AVEC LA DESORIENTATION, ET DES CLUSTERS SIO#X DE TYPE DONNEUR OU DOUBLE-DONNEUR DONT LA CINETIQUE DE FORMATION EST FAVORISEE PAR LA PRESENCE DU CARBONE. PAR AILLEURS, LES MESURES DE COURANT EBIC (ELECTRON BEAM INDUCED CURRENT) DEMONTRENT QUE L'UTILISATION DE PLAQUETTES FZ PERMET DE REDUIRE CONSIDERABLEMENT L'ACTIVITE RECOMBINANTE DE CES INTERFACES. D'UNE FACON GENERALE, CE TRAVAIL DEMONTRE QUE L'OPTIMISATION DES PROPRIETES ELECTRIQUES DE CES INTERFACES REQUIERT L'UTILISATION DE PLAQUETTES FZ ET PASSE PAR LE CONTROLE DE LEUR DESORIENTATION LORS DE L'ASSEMBLAGE

This book was released on 1986 with total page 792 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.

Available in PDF, EPUB and Kindle. Book excerpt: I am pleased to present a work which marks a milestone in the history of public works and, more precisely, in that of permanent structures—a comprehensive dictionary of Civil Engineering terms. Since the beginning of time, Man has always tried to find a means to clear the obstacles which nature erected to displace him. With the first tree trunk thrown across a river, man sought to improve the crossing structure. After the invention of the wheel, and to satisfy his thirst for conquest (Roman ways), and comfort (aqueducts), man built bridges that became a preremptory necessity to move quickly. Thus, Man started to build wooden and masonry works. With the passing centuries, the builders became masters in the art of building masonry works. Then came the Industrial Revolution and the advent of the steel (1864), which was closely followed by the invention of the reinforced concrete (1855). The need for railways and improving the road network inspired great works of crossing such as viaducts and tunnels. The boom of the railway network and the development of the car required the construction of an increasing number of new structures. This phenomenon continues today with hundreds of structures built each year throughout the world.
