Diffusion and Reactions in Fractals and Disordered Systems

• Broschiertes Buch

Produktbeschreibung

Fractal structures are found everywhere in nature, and as a consequence anomalous diffusion has far reaching implications in a host of phenomena. This book describes diffusion and transport in disordered media such as fractals, porous rocks and random resistor networks. Divided into four Parts, Part I contains material of general interest to statistical physics: fractals, percolation theory, regular random walks and diffusion, continuous time random walks and Lévy walks and flights. Part II covers anomalous diffusion in fractals and disordered media, while Part III serves as an introduction to the kinetics of diffusion-limited reactions. Part IV discusses the problem of diffusion-limited coalescence in one dimension. This book will be of particular interest to researchers requiring a clear introduction to the field. It will also be of interest to graduate students studying in areas of physics, chemistry, and engineering.

Rezensionen

'This book explains how fractals and scaling relationships are useful in understanding anomalous diffusion in disordered media. Definitions and explanations are clear and concise. There is a careful balance between text, equations and pictures. This is a well organised book. Illustrations are especially appealing and free from unnecessary elaboration. My guess is that its pedagogical and challenging style will indeed inspire many students to tackle problems with increased confidence.' Eric Dickinson, Chemistry in Britain
