At the frontiers of physics and chemistry lies the new and rapidly emerging area of complex plasma systems. The study of complex plasma systems that contain colloid nano/microscopic particles is now actively pursued in a diverse range of scientific fields — from plasma and gas discharge physics, to astrophysics, materials science and engineering. This book highlights, in a systematic, insightful, and perceptive way, the fundamental physics and industrial applications of complex plasmas, with emphasis on the conditions relevant to laboratory gas discharges and industrial plasma reactors. It provides a specialized and comprehensive description of the most recent theoretical, experimental, and modeling efforts to understand the unique properties of complex plasma systems involving the stability, dynamics, and self-organization of colloid particles and their associations. Special attention is focused on the physical understanding of up-to-date developments in major technological applications of micron and nano-sized particles. Each chapter is presented in a concise and comprehensive manner, with a categorized overview of the underlying physics followed by an in-depth description. The book will appeal to scientists and researchers as well as undergraduate and graduate students wishing to explore the flourishing interdisciplinary field of complex plasma systems.
