This book covers the fundamentals and applications of Carbon Nanofiber (CNF). In the first section, the initial chapter on the fundamentals of CNF is by Professor Maheshwar Sharon, the recognized "Father of Carbon Nanotechnology in India", which powerfully provides a succinct overview of CNFs. This is followed by a chapter on biogenics that have produced unique morphologies of CNF that makes them suitable to various applications. This is followed by a chapter that mainly focuses on nanocomposites, especially those involving nanocomposites of CNF. The role of nanocatalysts and composites in promoting and enhancing the synthesis and application of CNF is then covered, followed by an important chapter on the characterization of CNF.The second section of the book encompasses the various applications of CNF, such as its use as a possible superconductor to adsorb and store hydrogen, and as a microwave absorber. The application of CNF for environmental concerns is also detailed by assessing its usefulness in dye and heavy metal removal from polluted water. The applications that are addressed include lithium-ion battery, solar cell, antenna, cosmetics, usefulness in regenerative medicine, as well as various aspects of agrotechnology.

The scientific knowledge of nanoscience and nanotechnology is regarded to be a modern sciencethat evolved after Feynman's concept was formulated in the 1950s. However, Faraday and other scientists in the 19th century showed the science behind the small and its relation to optical properties. And it is now accepted that knowledge of using nanoparticles prevailed during the medieval period as well.This book takes the readers on a fascinating journey writing the history of nanotechnology based on the evidence of existence from the prehistoric period right up to the contemporary times. Nature utilized nanotechnology during the origin and expansion of the universe and especially in the evolution of living beings on our planet. Early civilizations in different parts of globe fabricated and used materials without having perception of their actual size.This unique historical view systematically evaluates the development of various applications of nanotechnology through the ages and the science behind it. Some of the issues covered include:* How old is nanotechnology?* Pre-historic evidence of knowledge of nanotechnology* Nanotechnology in ancient India* Ayurvedic Bhasma as nanomedicine* Mayan's knowledge of nanotechnology* Nanotechnology during the Roman empire and medieval period* European knowledge in the 19th century* Modern and contemporary history of nanotechnologyThis book is compilation of existence of scientific knowledge even of the people who existed before there were schools, universities and organized teaching. The author has scoured literature dating back to Mayan ... as well as historical observationsA systematic evaluation of development of various applications of nanotechnology and the science behind it is presented in this book under following headings-How old is Nanotechnology-Pre-historic Evidence of Knowledge of Nanotechnology-Nanotechnology in Ancient India-Ayurvedic Bhasma as Nanomedicine, its use prevails even today-Mayan's Knowledge of Nanotechnology-Nanotechnologists Flourished During Roman Empire and medieval period-European Nano knowledge That Led to Faraday Understands of Gold Nanoparticles-Contemporary History of Nanotechnology

Often described as a "miracle material", graphene's potential applications are extraordinary, ranging from nanoscale 'green' technologies, to sensors and future conductive coatings.This book covers the topic of 'graphene' - the history, fundamental properties, methods of production and applications of this exciting new material. The style of the book is both scientific and technical - it is accessible to an audience that has a general, undergraduate-level background in the sciences or engineering, and is aimed at industries considering graphene applications.As the graphene topic is a broad-reaching and rapidly moving field of research, the aim of this book is therefore to provide information about graphene and its current and future applications that are immediately implementable, relevant and concise. After reading this book, the reader will have sufficient knowledge and background to move forward independently into graphene R&D and to apply the knowledge therein. Although the book will be self-contained, each chapter has copious references to enable further reading, research and exploration of the chapter topics.
