Progress in Applied Materials Science gives an insight of materials used in medical fields such as bio-active components in osseointegrated implant, drug delivery system, antibacterial agent and cosmetic as well as in the environment fields such as anode materials. adsorbent and analytical sensor. The focused materials discussed in this book include bio-materials (hydroxyapatite, collagen and stainless steel, carbon-based materials (carbon nanotubes, activated carbon and other types of carbon). clay (kaolinite and other types of clay minerals) and polymer. Each chapter in this book discusses the fundamental aspects of the materials and their example of their application. The chapters also review current research related to applied materials science. This book is thus beneficial to researchers working on developing these materials for various applications
