Focusing on the cutting-edge technologies available in the field of photovoltaics, Solar Cell Nanotechnology explores the latest research and development activities related to organic, inorganic, and hybrid materials being used in solar cell manufacturing. Several chapters are dedicated to explaining the fundamentals of photovoltaics and nanomaterials utilized in the manufacturing of solar cells. Other essential subjects, such as microcontact printing, plasmonic light trapping, outdoor and indoor efficiency, luminescent solar concentrators, and photon management in photovoltaics, are comprehensively reviewed. Written for a broad audience, this is an essential book for engineers, nanotechnologists, and materials scientists.

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.

This book has been designed as a result of the author’s teaching experiences; students in the courses came from various disciplines and it was very difficult to prescribe a suitable textbook, not because there are no books on these topics, but because they are either too exhaustive or very elementary.  This book, therefore, includes only relevant topics in the fundamentals of the physics of semiconductors and of electrochemistry needed for understanding the intricacy of the subject of photovoltaic solar cells and photoelectrochemical (PEC) solar cells. The book provides the basic concepts of semiconductors, p:n junctions, PEC solar cells, electrochemistry of semiconductors, and photochromism.Researchers, engineers and students engaged in researching/teaching PEC cells or knowledge of our sun, its energy, and its distribution to the earth will find essential topics such as the physics of semiconductors, the electrochemistry of semiconductors, p:n junctions, Schottky junctions, the concept of Fermi energy, and photochromism and its industrial applications."The topics in this book are explained with clear illustration and indispensable terminology. It covers both fundamental and advanced topics in photoelectrochemistry and I believe that the content presented in this monograph will be a resource in the development of both academic and industrial research".—Professor Akira Fujishima, President, Tokyo University of Science, and Director, Photocatalysis International Research Center, Tokyo University of Science, Japan

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.

Concentrating on techniques for the detection and measurement of radioactivity, this book offers a guide to selecting the type of counter, type of source sample, duration for which the counting must be made, and the radiation emitted by the isotope for its efficient detection. It introduces a novel concept to explain not only the decay processes but also the selection of counting procedures for detecting and measuring radioactivity. The author builds up the foundation from the nature of the interaction of radiation with matter. He also highlights the differences between an ordinary chemical laboratory and a radiochemical one.

Highlighting the human applications of the science, this volume discusses the fundamental concepts and underlying science of bionanotechnology, and the bionanomachines that result from research into this exciting new field. Distilling the authors' research and groundbreaking original experimentation, chapters cover bionanomachines and their use with and manipulation of DNA, RNA, proteins, carbohydrates, and lipids. Well-documented and authoritative, this book offers students and scientists alike the foundational information required to advance this powerful and potentially life-altering field.

This book is designed to serve as a textbook for core courses offered to postgraduate students enrolled in chemistry. The book covers various topics of nuclear chemistry like Shell model, fission/fusion reaction, natural radioactive equilibrium series, nuclear reactions carried by various types of accelerators.
