This book is a systematic introduction to the new and rapidly evolving field of patterns in granular materials. Granular matter is usually defined as a collection of discrete macroscopic solid ...particles (grains) with a typical size large enough that thermal fluctuations are negligible. Despite this seeming simplicity, properties of granular materials set them apart from conventional solids, liquids, and gases due to the dissipative and highly nonlinear nature of forces among grains. The last decade has seen an explosion of interest to nonequilibrium phenomena in granular matter among physicists, both on experimental and theoretical sides. Among these phenomena, one of the most intriguing is the ability of granular matter upon mechanical excitation to form highly ordered patterns of collective motion, such as ripples, avalanches, waves, or bands of segregated materials. This book combines a review of experiments with exposition of theoretical concepts and models introduced to understand the mechanisms of pattern formation in granular materials. The unique feature of this book is a strong effort to extend concepts and ideas developed in granular physics beyond the traditionally defined boundaries of the granular physics towards emergent fields, especially in biology, such as cytoskeleton dynamics, molecular motors transport, ordering of cells and other active (self-propelled) particles, dynamic self-assembly, etc.
The book gives an overview of the dynamic behavior of dislocations and its relation to plastic deformation. It introduces the general properties of dislocations and treats the dislocation dynamics in ...some detail. Finally, examples are described of the processes in different classes of materials, i.e. semiconductors, ceramics, metals, intermetallic materials, and quasicrystals. The processes are illustrated by many electron micrographs of dislocations under stress and by video clips taken during in situ straining experiments in a high-voltage electron microscope showing moving dislocations. Thus, the users of the book also obtain an immediate impression and understanding of dislocation dynamics. TOC:1. Introduction.- 2. Experimental methods.- 3. Properties of dislocations.- 4. Dislocation motion.- 5. Dislocation kinetics, work-hardening and recovery.- 6. Semiconductors.- 7. Ceramic single crystals.- 8. Metallic alloys.- 9. Intermetallic alloys.- 10. Quasicrystals.- 11. Conclusion.

This book introduces the principles of electrochemistry with a special emphasis on materials science. This book is clearly organized around the main topic areas comprising electrolytes, electrodes, ...development of the potential differences in combining electrolytes with electrodes, the electrochemical double layer, mass transport, and charge transfer, making the subject matter more accessible. In the second part, several important areas for materials science are described in more detail. These chapters bridge the gap between the introductory textbooks and the more specialized literature. They feature the electrodeposition of metals and alloys, electrochemistry of oxides and semiconductors, intrinsically conducting polymers, and aspects of nanotechnology with an emphasis on the codeposition of nanoparticles. This book provides a good introduction into electrochemistry for the graduate student. For the research student as well as for the advanced reader there is sufficient information on the basic problems in special chapters. The book is suitable for students and researchers in chemistry, physics, engineering, as well as materials science.- Introduction into electrochemistry \- Metal and alloy electrodeposition \- Oxides and semiconductors, corrosion \- Intrinsically conducting polymers \- Codeposition of nanoparticles, multilayers
Materials Chemistry addresses inorganic-, organic-, and nano-based materials from a structure vs. property perspective. The second edition continues to offer innovative coverage and a practical ...approach throughout the text.
This article sketches the activities undertaken by the experts of the Rotary Club Roma Castelli Romani aimed at safeguard and recuperate the original artistic value of the Fountain of Piazza Castel ...gandolfo. Utilizing modern 3D scanning techniques a first phase have seen the analysis of the fountain in order to better understand the decay reasons of the stone and in order to reconstruct the border profiles for a subsequent phase of restauration. New promising techniques of restauration will be considered.
In June 1927, the Kulturwissenschaftliche Bibliothek Warburg celebrated "forty years of bibliophily". On the occasion of the sixtieth birthday of his brother Max, Aby Warburg organized a guided tour ...of his library and a photographic exhibition presented with original documents: one example of the practical side of the "Bild und Wort" method. These two terms were used by Aby Warburg to describe a theme of his research, namely the complex relation between iconographic and textual tradition and the theory of the function of the human visual memory. At the same time, "image and word" were research tools, experimented by Warburg in structuring his lectures as reading plus slideshow plus guided visit of the panels and in creating a photographic collection in his Library. It was from this lecturing and exhibiting practice, and from the desire to collect and disseminate his research in a suitable manner, that Warburg's project for an atlas-book, entitled Mnemosyne, took its origin and form. "The" Mnemosyne was intended to be a work dedicated to the investigation of the dynamics of the Western tradition and its cultural memory, focusing on the examples provided by the "posthumous life" of antiquity during the Renaissance.
