"This book presents the basics and characterization of defects at oxide surfaces. It provides a state-of-the-art review of the field, containing information to the various types of surface defects, describes analytical methods to study defects, their chemical activity and the catalytic reactivity of oxides. Numerical simulations of defective structures complete the picture developed. Defects on planar surfaces form the focus of much of the book, although the investigation of powder samples also form an important part. The experimental study of planar surfaces opens the possibility of applying the large armoury of techniques that have been developed over the last half-century to study surfaces in ultra-high vacuum. This enables the acquisition of atomic level data under well-controlled conditions, providing a stringent test of theoretical methods. The latter can then be more reliably applied to systems such as nanoparticles for which accurate methods of characterization of structure and electronic properties have yet to be developed. The book gives guidance to tailor oxide surfaces by controlling the nature and concentration of defects. The importance of defects in the physics and chemistry of metal oxide surfaces is presented in this book together with the prominent role of oxides in common life. The book contains contributions from leaders in the field. It serves as a reference for experts and beginners in the field."

La 4e de couverture indique : "Inodores, incolores, invisibles et passe-partout grâce à leur très petite taille, les nanomatériaux ont envahi depuis quelques décennies les objets du quotidien : bonbons et chocolats, peinture et colle, vêtements et médicaments, yaourts et plats cuisinés, crème de beauté et dentifrice... Même les emballages en regorgent ! Désormais il faut donc compter avec eux. Nous les inhalons et les ingurgitons sans même nous en apercevoir tant leur cheminement à travers l'organisme est sinueux et énigmatique. Car avant même d'évaluer leurs capacités à traverser ou non des barrières biologiques, avant même de juger de leur utilité, les voilà sur place et en masse. Où réside le génie de ces Lilliputiens ultraréactifs ? Ils augmentent les rendements des panneaux solaires, rendent les capteurs hypersensibles, démultiplient la puissance de calcul des ordinateurs, réinventent l'électronique, élaborent des médicaments sans effets secondaires... Faut-il en avoir peur ? Les encenser ou les boycotter ? Arrêter d'en produire ou, au contraire, foncer dans cette course mondiale qui a débuté il y a à peine deux décennies ? A travers une série de rencontres avec des spécialistes, l'auteure souligne la complexité du problème dès lors que l'on y porte un regard global, alerte contre les solutions simplistes, et plaide pour que le consommateur soit pleinement informé. Car dans ce nanomonde qui s'ouvre, c'est notre vigilance et notre sens civique qui feront toute la différence."
