This unique reference critically analyzes the use and application of all major physical methods for determining the structure and behavior of catalysts. Each chapter presents a detailed description of a technique and its theoretical basis, a definition of its field of application, and examples of validity and limitation. Extensive cross referencing between chapters ensures seamless continuity as well as a holistic view of the field. This new edition covers the substantial progress made since its predecessor in characterization of catalysts.

Crystal growth and nucleation are treated in the specialized literature in different ways depending on the discipline in question (physics, physical chemistry, chemical engineering) and on the theoretical approaches (atomistic vs continuum approach as regards crystal growth, phase vs chemical concept as regards nucleation). This book relates the different approaches to one another, giving preference to atomistic treatments by the methods of statistical thermodynamics and chemical kinetics. This unified approach also facilitates an understanding of some related phenomena of surface physics, such as adsorption, wetting etc. The book allows research novices and graduate students to get an insight into the physics of the phenomena and to interpret some of the experimental results.

The book in hand presents advanced methods of brittle fracture and fatigue assessment. The Neuber concept of fictitious notch rounding is enhanced with regard to theory and application. The stress intensity factor concept for cracks is extended to pointed and rounded corner notches as well as to locally elastic-plastic material behaviour. The averaged strain energy density within a circular sector volume around the notch tip is shown to be suitable for strength-assessments. Finally, the various implications of cyclic plasticity on fatigue crack growth are explained with emphasis being laid on the DJ-integral approach. This book continues the expositions of the authors’ well known reference work in German language ‘Ermüdungsfestigkeit – Grundlagen für Ingenieure’ (Fatigue strength – fundamentals for engineers).

This book consists of two strongly interweaved parts: the mathematical theory of stochastic processes and its applications to molecular theories of polymeric fluids. The comprehensive mathematical background provided in the first part should be equally useful in many other branches of engineering and the natural sciences. As a benefit from the second part one gains a more direct understanding of polymer dynamics, one can more easily identify exactly solvable models, and one can develop efficient computer simulation algorithms in a straightforward manner. In view of the many examples and exercises, on the one hand, and the numerous applications to problems from the front line of science, on the other hand, this volume may be used equally well as a basic textbook or as an up-to-date reference book.
