Neutrons, X-rays, and Light: Scattering Methods Applied to Soft Condensed Matter, Second Edition addresses the possibilities provided by scattering techniques in the study of soft matter. It fills the gap between fundamental scattering processes, which are described by the general theoretical framework of elastic and quasi-elastic interaction of radiation with matter and state-of-the-art applications to specific soft matter systems. The first part of the book is dedicated to the use of general principles for the measurement and analysis of scattered intensity: elementary scattering process, data reduction, general theorems, and reciprocal space and its link to structural and dynamical information in direct space. In the second part, methods and techniques are further discussed, including resolution effects, contrast variation, static and dynamic light scattering, quasi-elastic neutron scattering, and reflectometry and grazing incidence techniques. Part three deals with the state of the art of scattering studies of typical soft matter systems (polymers, self-assembled surfactant systems, microemulsions, liquid crystals, colloids, aggregates, biological systems) with dedicated chapters for particle interactions, and modelling. Part four highlights special applications, from turbid media to scattering under external constraints, and industrial applications.
