Sommario/riassunto |
|
Entropy Theory and its Application in Environmental and Water Engineering responds to the need for a book that deals with basic concepts of entropy theory from a hydrologic and water engineering perspective and then for a book that deals with applications of these concepts to a range of water engineering problems. The range of applications of entropy is constantly expanding and new areas finding a use for the theory are continually emerging. The applications of concepts and techniques vary across different subject areas and this book aims to relate them directly to practical problems |

and applications, such as adsorption, catalysis, and membranes. The book is instrumental in terms of showing the scale-up production of desired fibers that ensure the control of the structure–properties relationship for developing effective water treatment technologies. Every chapter ends with a special section for highlighting research challenges and breakthroughs, so that scientists can explore these opportunities and discover new directions for future developments. Material scientists, nanotechnologists, chemists, engineers, water specialists, and environmentalists will be inspired by the information on electrospun nanofibrous materials to be foundin the book. The wide variety of new ideas and recommended future reading will encourage early-career scientists working in this field to design new experiments and practices. The book is useful for college and university-level students enrolled in project courses in materials science and related fields. |
