At about the time I was a student in the 1930's, it had become increasingly evident that all the elements existing on the Earth today had already been discovered. Scientists then began "discovering" new elements by means of their artificial synthesis and some of the man-made elements found important military as well as industrial applications. I have often wondered, however, if the importance of these artificial elements may not have been overly emphasized by contemporary scientists for their practical applications. It seemed to me that these man-made elements were destined to play an important role du ring the second half of the 20th century in the study of the origin of the elements in the Universe. This subject of study, which dates back to the days of ancient Greek philoso phers, may be regarded as the most fundamental in the entire compass of our modetn science. Since I joined the faculty of the University of Arkansas in the early 1950's, I have had the good fortune of being able to maintain a long-range research project, the ultimate goal of which was to elucidate the origin of the elements. I have presented the results from these and related investigations on numerous occasions. While serving as a tour speaker of the American Chemical Society for many years, I have had the privilege of visiting many ofthe local sections to present a lecture on the origin ofthe elements.

Based on an American Chemical Society Symposium organized by Professors Glenn Seaborg and Oliver Manuel, this volume provides a comprehensive record of different views on this important subject at the end of the 20th century. They have assembled a blend of highly respected experimentalists and theorists from astronomy, geology, meteoritics, planetology and nuclear chemistry and physics to discuss the origin of elements in the solar system. The intent was to include all points of view and let history judge their validity.
The fourth edition of "The Chemistry of the Actinide and Transactinide Elements" comprises all chapters in volumes 1 through 5 of the third edition (published in 2006) plus a new volume 6. To remain consistent with the plan of the first edition, “ ... to provide a comprehensive and uniform treatment of the chemistry of the actinide [and transactinide] elements for both the nuclear technologist and the inorganic and physical chemist,” and to be consistent with the maturity of the field, the fourth edition is organized in three parts. The first group of chapters follows the format of the first and second editions with chapters on individual elements or groups of elements that describe and interpret their chemical properties. A chapter on the chemical properties of the transactinide elements follows. The second group, chapters 15-26, summarizes and correlates physical and chemical properties that are in general unique to the actinide elements, because most of these elements contain partially-filled shells of 5f electrons whether present as isolated atoms or ions, as metals, as compounds, or as ions in solution. The third group, chapters 27-39, focuses on specialized topics that encompass contemporary fields related to actinides in the environment, in the human body, and in storage or wastes. Two appendices at the end of volume 5 tabulate important nuclear properties of all actinide and transactinide isotopes. Volume 6 (Chapters 32 through 39) consists of new chapters that focus on actinide species in the environment, actinide waste forms, nuclear fuels, analytical chemistry of plutonium, actinide chalcogenide and hydrothermal synthesis of actinide compounds. The subject and author indices and list of contributors encompass all six volumes.
The subject of this book is the physico-chemical theory of the origin of life. Although this theory is still in statu nascendi, it has been developed in recent years to the point where a coherent presentation is possible. The book is intended as an introductory text for students of physics, chemistry or biology. This interdisciplinary aim has necessitated a choice of material based on the lowest common denominator of physicists and biologists. In particular, the predominantly mathematical and biological sections have been presented at the most elementary l.evel possible. The less mathematically inclined reader can omit Sections (5.3)-(5.5), (5.7)-(5.10), (6.2), (6.3), (9.1)-(9.3), (12.1) and (13.3) without losing the overall view. For critical reading of the manuscript, for discussions and for many useful suggestions I wish to thank M. Eigen (Gottingen), w.e. Gardiner (Austin), D. Porschke (Gottingen), P. Schuster (Vienna), P.R. Wills (Auckland) and P. Woolley (Berlin). The translation of the original, German manuscript into English was kindly undertaken by Paul Woolley. During this and subsequent stages of revision he introduced a great many improvements in the text and the presentation of material. My particular thanks are due to him for his decisive contribution to this book. Last of all I wish to thank Ingeborg Lechten for typing the text in its various stages of evolution. The completion of this book is largely to be attributed to her patience and efficiency.
The third edition of this classic in the field is completely updated and revised with approximately 30% new content so as to include the latest developments. The handbook and ready reference comprehensively covers nuclear and radiochemistry in a well-structured and readily accessible manner, dealing with the theory and fundamentals in the first half, followed by chapters devoted to such specific topics as nuclear energy and reactors, radiotracers, and radionuclides in the life sciences. The result is a valuable resource for both newcomers as well as established scientists in the field.
This text provides a non-mathematical descriptive approach to key concepts and contemporary topics in the sciences. Chapters on chemical bonding, biochemistry, cancer and the atmosphere are interspersed with such chapters as The Alchemist's Dream, Newsworthy Molecules and Wall Street Chemistry. The book employs a historical story-line through the text. For example, the Hindenberg serves to amplify the subtle, yet catastrophic, differences between helium and hydrogen.
This handbook gives a complete and concise description of the up-to-date knowledge of nuclear and radiochemsitry and applications in the various fields of science. I is based on teaching courses and on research for over 40 years. The book is addressed to any researcher whishing sound knowledge about the properties of matter, be it a chemist, a physicist, a medical doctor, a mineralogist or a biologist. They will all find it a valuable source of information about the principles and applications of nuclear and radiochemistry. Research in radiochemistry includes: Study of radioactice matter in nature, investigation of radioactive transmutations by chemical methods, chemistry of radioelements etc. Applications include: Radionuclides in geo- and cosmochemistry, dating by nuclear methods, radioanalysis, Mössbaur spectroscopy and related methods, behaviour of natural and man-made radionuclides in the environment, dosimetry and radiation protection. All subjects are presented clearly and comprehensibly, and in logical sequence. Detailed derivations of equations are avoided and relevant information is compiled in tables. The recent edition of the multi-coloured Karlsruhe 'Chart of the Nuclides' is included. Clearly a standard work by an author with extensive experience in research and teaching.
John Emsley's Nature's Building Blocks was published in paperback in 2003. In this readable, informative, and fascinating guide to the elements are entries on each of the 100-odd chemical elements, arranged alphabetically from actinium to zirconium. Each entry comprises an explanation of where the element's name comes from, followed by Body element (the role it plays in living things), Element of history (how and when it was discovered), Economic element (what it is used for), Environmental element (where it occurs, how much), Chemical element (facts, figures, and narrative), and Element of surprise (an amazing, little-known fact). Since publication of the first edition there have been a number of developments. Three new chemical elements have been named and validated: darmstadtium, roetgenium, and copernicium and the section on 'transfermium elements' has now been incorporated into the main part of the book. Economic uses of elements have grown, and some quite rare elements such as Scandium are now economically important, along with updates to elements such as gold due to new roles in industry. Fully revised and updated for 2010, this browsable compendium holds a wealth of useful information.
Fundamentals of Radiochemistry presents a comprehensive overview of the principles, objectives, and methods of radiochemistry and how they are applied in various fields of chemistry. Topics covered include characteristics of radioactivity and radioactive matter, the chemistry of ephemeral radionuclides, actinides of high atomic number, positronium, and physicochemical behavior of systems containing one or more compounds at tracer or sub-tracer concentration. Numerous appendices are included to provide additional detail to information presented in chapters. Because Fundamentals of Radiochemistry is the first book to discuss what chemical information can be obtained with sub-tracer amounts, it is essential reading for inorganic chemists, radiochemists, analytical chemists, nuclear chemists and others interested in the topic.
