Smart Materials for Smart Living has a wide range of materials that are involved in the things that govern our day to day lives. Applications of SMNFs are used in different areas such as filtration media, gas sensing and a great deal of biomedical applications too. The treatment of heart blockage and brain hemorrhage has been significantly affected by these materials. Due to their extremely small pore size, large surface volume ratio and being light in weight, they prove to be better materials in solar cells, batteries and many other transducer applications. In today’s modern world where everyone is moving towards advancement, humanity forgets to keep up with sustainable development. Hence, the responsibility rests on the shoulders of researchers to make materials that not only keep us updated with the modern world, but also help us keep the environment clean. Keeping this point of view in mind, this book consists of chapters that deal with lead free and non-toxic materials. Population, industrialisation and agricultural development are a few factors that led to the degradation of environment. This book helps us to know how different species are connected with each other. There are different technologies used for the conservation of biodiversity and life. All chapters will help readers understand what the role of materials for different applications are and how to sustain biodiversity; the different sustainable approaches; and the various steps adopted by global bodies for conservation. A healthy life can only be achieved by a proper balance of materials in the body as well as surroundings.
