This special issue contains selected peer-reviewed papers which were presented at the Third International Conference on Diffusion in Solids and Liquids (DSL-2007), held at the Hotel Pestana Alvor Praia, Algarve, Portugal during the 4th-6th July, 2007.

This book describes the central aspects of diffusion in solids, and goes on to provide easy access to important information about diffusion in metals, alloys, semiconductors, ion-conducting materials, glasses and nanomaterials. Coverage includes diffusion-controlled phenomena including ionic conduction, grain-boundary and dislocation pipe diffusion. This book will benefit graduate students in such disciplines as solid-state physics, physical metallurgy, materials science, and geophysics, as well as scientists in academic and industrial research laboratories.
