Scientists, engineers, and technologists in many fields need a knowledge of chemistry because of the importance of chemistry in diverse technologies. In addition, to "classical" topics of chemistry, the new Encyclopedia covers nanotechnology, fuel cell technology, green chemistry, forensic chemistry, supramolecular chemistry, combinatorial chemistry, materials chemistry, and proteomics. This fifth print edition has been revised and updated, and includes over 200 new articles, as well as 1,300 updated articles.

An alphabetic index of chemistry terms with emphasis on advanced processes, strategic raw materials, chemistry of metals, energy sources and conservation, wastes and pollution, analytical instrumentation, growing uses of

Captures the expansion of chemistry into new fields and the impact related sciences have had on the increasingly interdisciplinary nature of chemistry. In addition to "classic" topics in chemistry, it covers such new topics as nanotechnology, fuel cell technology, combinational chemistry, and materials science.

Volume two begins with Goethe's theories of affinities, i.e. the chemical reaction view of human life in 1809. This is followed by the history of how the thermodynamic (1876) and quantum (1905) revolutions modernized chemistry such that affinity (the 'force' of reaction) is now viewed as a function of thermodynamic 'free energy' (reaction spontaneity) and quantum 'valency' (bond stabilities). The composition, energetic state, dynamics, and evolution of the human chemical bond A?B is the centerpiece of this process. The human bond is what gives (yields) and takes (absorbs) energy in life. The coupling of this bond energy, driven by periodic inputs of solar photons, thus triggering activation energies and entropies, connected to the dynamical work of life, is what quantifies the human reaction process. This is followed by topics including mental crystallization, template theory, LGBT chemistry, chemical potential, Le Chatelier's principle, Muller dispersion forces, and human thermodynamics.

Advancements in science and engineering have occurred at a surprisingly rapid pace since the release of the seventh edition of this encyclopedia. Large portions of the reference have required comprehensive rewriting and new illustrations. Scores of new topics have been included to create this thoroughly updated eighth edition. The appearance of this new edition in 1994 marks the continuation of a tradition commenced well over a half-century ago in 1938 Van Nostrand's Scientific Encyclopedia, First Edition, was published and welcomed by educators worldwide at a time when what we know today as modern science was just getting underway. The early encyclopedia was well received by students and educators alike during a critical time span when science became established as a major factor in shaping the progress and economy of individual nations and at the global level. A vital need existed for a permanent science reference that could be updated periodically and made conveniently available to audiences that numbered in the millions. The pioneering VNSE met these criteria and continues today as a reliable technical information source for making private and public decisions that present a backdrop of technical alternatives.

Prepared by the IUPAC Physical Chemistry Division this definitive manual, now in its third edition, is designed to improve the exchange of scientific information among the readers in different disciplines and across different nations. This book has been systematically brought up to date and new sections added to reflect the increasing volume of scientific literature and terminology and expressions being used. The Third Edition reflects the experience of the contributors with the previous editions and the comments and feedback have been integrated into this essential resource. This edition has been compiled in machine-readable form and will be available online.

In-depth, current and accurate information on 112 known chemical elements. For younger and middle school students, yet appropriate for high school students, too.

This lavishly illustrated encyclopedia--which Library Journal praised as "wonderfully illustrated" and "a pleasure to browse"--is now available in a revised edition. Here is a wealth of up-to-date information--more than 6,500 alphabetically arranged entries, each written by an expert in the field, covering virtually every aspect of science and technology, from the structure of atoms to the functioning of the cell. Readers will find brief informative entries covering subject areas such as astronomy, chemistry, biology, botany, engineering, physics, and medicine, to name a few. In addition, dozens of major topics--such as the Solar System or the Human Body--receive expanded, one- or two-page spreads. The volume also offers 700 special-feature boxes that explain key topics, inventions, and processes, ranging from air conditioners to binary stars; a 40-page time-line detailing significant moments in the history of science and technology; plus a ten-page ready reference section. And the entire volume boasts marvelous illustrations--over a thousand color diagrams, tables, and photographs. This up-to-date reference is beautifully designed, highly informative, and easy to use--an ideal reference for high school and college students as well as anyone interested in science.
