Few times an unsolved issue in science has dealt with a larger number of approaches or theories intending to shed light on it and few times this has been done from so different, often orthogonal perspectives. This book covers a hot topic, one of the unsolved problems not just in chemistry, but in science

"Creating the Molecules of Life discusses origins, including the Big Bang, and the origin of the elements. With a complete presentation and explanation, this book provides evidence that the molecules of life are produced in outer space and how the SNAAP model purports to explain that origin. Extremophiles, which explains that evolution is robust enough to create life forms in a wide variety of conditions, is also presented. Readable for those at the upper undergraduate level, mathematics associated with coupling the nuclear spins to the molecular chirality is discussed. An accompanied appendix is provided to support mathematics."--Source : résumé de l'éditeur.

This book presents the fascinating formation of the first simple bioorganic molecules and describes the hidden aspects of chiral compounds, which raise questions on the molecular beginnings of life. The occurrences of extraterrestrial, non-standard amino acids in meteorites are dealt with in detail, as well as their subsequent transfer to proteinogenic amino acids. The concept of asymmetric organo-catalysis for the synthesis of carbohydrates and ribonucleosides are considered. The notion of a single amino acid that functions as an enzyme is developed. Attempts to simulate ancient world scenarios are critically reviewed. There is a special focus on ribozymes and the resulting RNA world. Combinations of different world scenarios are discussed in view of an on-going evolution. The currently most plausible hypotheses and visions of ancient world scenarios that led to today’s DNA world are also provided. Included is a pre-cellular world of viruses that is presented for the first time.

Where were the amino acids, the molecules of life, created: perhaps in a lightning storm in the early Earth, or perhaps elsewhere in the cosmos? This book argues that at least some of them must have been produced in the cosmos, and that the fact that the Earthly amino acids have a specific handedness provides an important clue for that explanation. The book discusses several models that purport to explain the handedness, ultimately proposing a new explanation that involves cosmic processing of the amino acids produced in space. The book provides a tour for laypersons that includes a definition of life, the Big Bang, stellar nucleosynthesis, the electromagnetic spectrum, molecules, and supernovae and the particles they produce.

How can we study one of the most elusive molecular properties, chirality, using nuclear interactions with the magnetic field that are apparently insensitive to handedness? This book answers this question from the physicochemical point of view by providing a clear, coherent, and comprehensive review of methods used in NMR studies of chirality. Presented arguments based on fundamental physical and chemical laws and in-depth descriptions of new methods utilizing purely physical interactions are mainly addressed to spectroscopists in both academia and industry. The introductory chapters provide the reader with the basics of NMR spectroscopy as a tool for the study of chiral compounds, and those more interested in the methods of chiral discrimination will benefit from the brief description of their common points and reasons why some of them may or may not work. In the following chapters, the book shows rapid progress in a newly emerging field of chirality-sensitive NMR, in particular, a search for effects that give direct information about the absolute configuration of a molecule.

Discover a new generation of organic nanomaterials and their applications Recent developments in nanoscience and nanotechnology have given rise to a new generation of functional organic nanomaterials with controlled morphology and well-defined properties, which enable a broad range of useful applications. This book explores some of the most important of these organic nanomaterials, describing how they are synthesized and characterized. Moreover, the book explains how researchers have incorporated organic nanomaterials into devices for real-world applications. Featuring contributions from an international team of leading nanoscientists, Organic Nanomaterials is divided into five parts: Part One introduces the fundamentals of nanomaterials and self-assembled nanostructures Part Two examines carbon nanostructures—from fullerenes to carbon nanotubes to graphene—reporting on properties, theoretical studies, and applications Part Three investigates key aspects of some inorganic materials, self-assembled monolayers, organic field effect transistors, and molecular self-assembly at solid surfaces Part Four explores topics that involve both biological aspects and nanomaterials such as biofunctionalized surfaces Part Five offers detailed examples of how organic nanomaterials enhance sensors and molecular photovoltaics Most of the chapters end with a summary highlighting the key points. References at the end of each chapter guide readers to the growing body of original research reports and reviews in the field. Reflecting the interdisciplinary nature of organic nanomaterials, this book is recommended for researchers in chemistry, physics, materials science, polymer science, and chemical and materials engineering. All readers will learn the principles of synthesizing and characterizing new organic nanomaterials in order to support a broad range of exciting new applications.

Colour and the Optical Properties of Materials carefully introduces the science behind the subject, along with many modern and cutting-edge applications, chosen to appeal to today's students. For science students, it provides a broad introduction to the subject and the many applications of colour. To more applied students, such as engineering and arts students, it provides the essential scientific background to colour and the many applications. New to this Edition: The chapter framework of the first edition will be retained, with each chapter being substantially rewritten and some material would be relocated. Some chapters will be rewritten in a clearer fashion, e.g. There have been no significant advances in the understanding of rainbows recently, but the text could be clarified and improved. Colour has been an important attribute of many nano-particle containing systems, such as quantum dots. This aspect will be included, e.g. the colour of gold ruby glass, described in Chapter 5 as part of scattering phenomena now is better treated in terms of gold nanoparticles and surface plasmons. This would probably be transferred to Chapter 10 and considered in tandem with the colour of metals such as copper, silver and gold. A similar state of affairs applies to silver nanoparticles and polychromic glass. Some chapters will include extensive new material, e.g. Chapter 8, colours due to molecular processes [organic LEDs etc], and Chapter 12, Displays, [touch screen technologies]. For all chapters it would be intended to take into account the current scientific literature up to the time of submission – say up to the end of 2009. The end of chapter Further Reading sections would reflect this up-to-date overview. The end of chapter problems will be strengthened and expanded.
