Diffraction from Materials provides the basic information concerning crystal symmetry, the kinematic scattering theory, as well as the physical properties of x-rays, electrons, and neurons. This book explores the crystalline nature of metals, semiconductors, and insulators.
Organized into eight chapters, this volume starts with an overview of the basic ideas associated with the arrangements of atoms in crystals to help readers understand why diffraction studies are useful in learning about crystals. This book considers the analytical and geometrical methods to represent the symmetry relationships for the atoms in crystals. Other chapters examine the production of radiation suitable for diffraction from materials. The final chapter examines the various techniques for x-ray topography, including the Schulz technique, the Guinier and Tennevin technique, and the Berg–Barret method.
This book is a valuable resource for electrical, civil, mechanical, and chemical engineers. This text will also be useful to materials scientists, chemists, biologists, and physicists.

Diffusion in Solids: Recent Developments provides an overview of diffusion in crystalline solids. This book discusses the various aspects of the theory of diffusion.
Organized into nine chapters, this volume starts with a discussion on the process of diffusion in solids. This book then examines the tools that supplement the conventional diffusion measurements, including electromigration, ionic conductivity, isotope effects, and vacancy wind effects. This text explores the molecular dynamic calculation by which the interatomic forces must be assumed. Other chapters discuss the method of measurement of the isotope effect on diffusion, which is the most powerful method of determining relevant information about the correlation factor. This volume extensively discusses diffusion in organic and amorphous materials, as well as interstitial diffusion in solids. The final chapter deals with ionic motion and diffusion in various groups of materials called fast ionic conductors.
Solid-state physicists, materials scientists, physical chemists, and electrochemists will find this book extremely useful.

En esta tesis se avanza en el conocimiento de los procesos difusivos que tienen lugar en el espacio de acciones de sistemas Hamiltonianos casi-integrables. Fundamentalmente, se estudia la difusión de Arnold que tiene lugar a lo largo de una resonancia, considerando un flujo Hamiltoniano con tres grados de libertad cuya superficie de energía no perturbada es convexa en el espacio de acciones. Además, se estudia la difusión en un mapa simpléctico 4D a priori inestable, sobre el cual se aplica un método semi--numérico para predecir aproximadamente el coeficiente de difusión asociado a una de las acciones, y se corrobora numéricamente que el proceso satisface una ecuación de Fokker-Planck.
