The present volume deals with four diverse areas of considerable interest and importance: organic electronic device physics, charge density waves in nanocrystals, shape memory alloys, and grain growth of cellular structures.

First part presents a comprehensive survey of the basic physics underlying organic electronic devices, in particular, the most studied examples of light-emitting diodes (LEDs) and field-effect
transistors. This exciting new area is rapidly unfolding in some ways, as the authors point out, analogously to the early development of inorganic semiconductor devices.
The second part describes the formation of charge density waves (CDWs) in 2D nanostructures, in particular, transition metal dichalcogenides (TMDs).
The third part is devoted to the vibrational propertles of shape-memory alloys. The shape-memory effect in certain metallic alloys is made possible by a reversible martensitic transformation. Shape-memory alloys have several technological applications, from safety valves to, most recently, micro-electromechanical systems (MEMS).
The last part reviews our understanding of the evolution of materials that are divided up into cells by internal surfaces, such as polycrystals or foams. The evolution is a type of coarsening, driven by a
continuous decrease in the total interfacial area. In polycrystals the phenomenon is known as grain growth.
