Hybrid systems, inheriting the merits of their predecessors, exhibit extraordinary strengths to face various challenges and hostile environments. Hybrid systems have the ability to inspire and encourage researchers and engineers to propose novel ideas, which allow for more applications and devices in physics, chemistry and biology. In this book, the authors introduce various applications of hybrid methods, hybrid models, hybrid systems and hybrid materials by taking advantage of high performance and better implementation of hybrid structures. This book covers both theoretical methods and practical realizations from distinct disciplines by introducing the recent advances of hybrid structures.
