Rapid evolution of trade, cultural and human relations provides the qualitative and quantitative enhancement of international collaborations, linking the countries with different economical and technological level. Delocalization of High-Tech industry inevitably leads to development of the material science and engineering researches in emergent countries, requiring transfer of know-how, restructuration of basic research and educational networks. This book presents the contributions of participants of the Advanced Research Workshop "Smart Materials for Energy, Communications and Security" (ARW SMECS; www.smecs.ferroix.net), organized in December 2007 in Marrakech in frame of the "NATO - Science for Peace" program. The objective of this event was the attempt to overview several hot topics of material physics related with problems of modern society: transformation and storage of energy, treatment and transmission of information, environmental security issues etc., with the focus of their implementation in Mediterranean Dialogue (MD) countries: Algeria, Egypt, Mauritania, Morocco and Tunisia. The workshop is an important stage in developing of the research network "Mediterranean Electronic Materials" - MEM (www.reseau-MEM.org), that has an objective to encourage the inter-Maghreb and Europe-Maghreb collaborative studies in the area of electroactive materials.
