Materials science influences all aspects of society, including the current challenges of environmental issues and of sustainable energy. It also impacts our daily life, because it studies common materials like nanomaterials, composites, hybrid materials, glass, and plastic. Materials science tries to improve these materials in ways such as adding scratch resistance to glass. This science also commonly studies composite materials. This book was motivated by the desire to broaden knowledge and use this knowledge to develop new materials for the utility of mankind. There are innumerable tools currently available that focus on specific knowledge that can largely serve the scientific community. However, this book also explores social issues and outlines applications of different materials. Additionally, this book presents research-based practices related to the usage of advanced materials and covers the application of nanomaterials in solar energy and medicine. The didactic approach of this book is perfectly suited to science and engineering students, as well as to biologists, physicists, or chemists who are not specialized in materials but who, nevertheless, wish to learn about this discipline. This work will also be appreciated by specialists in a particular aspect of materials science wishing to have a global view on the subject and to position their activity in a wider context.
