This book focuses on the fractal aspects of materials and disordered systems. Disorder plays a critical role in many naturally occurring and manufactured materials, both at the microscopic level (e.g., glasses) and the macroscopic level (e.g., foams, dendritic alloys, porous rock). The book addresses the dynamical processes involved in the formation and characterization of a wide range of disordered materials. Topics include: porous media; colloids; chemical reactions; dynamical aspects of the liquid-glass transition; disordered materials and surfaces and scaling and nanostructures.
