This book begins by presenting the fundamental and elementary basis and theoretical tools for the interpretation and development of solid-gas interaction models. Chemical, physical and electrochemical aspects are presented from a phenomenological, thermodynamic and kinetic point of view. The theoretical aspects of electrical properties at the surface of a solid are also covered, to provide greater accessibility for those with a background in physical chemistry.
The second part of the book is devoted to the development of devices for gas detection, using a system approach. Methods for experimental investigation of solid-gas interactions and phenomena are first described, and then results are presented to support the contribution made by large metallic elements to the electronic processes associated with solid-gas interactions.
