That fossilized chart on every classroom wall — isn't that The Periodic Table? Isn't that what Mendeléev devised about a century ago? No and No. There are many ways of organizing the chemical elements, some of which are thought-provoking, and which reveal philosophical challenges. Where does hydrogen 'belong'? Can an element occupy more than one location on the chart? Which are the Group 3 elements? Is aluminum in the wrong place? Why is silver(I) like thallium(I)? Why is vanadium like molybdenum? Why does gold form an auride ion like a halide ion? Does an atom 'know' if it is a non-metal or metal? Which elements are the 'metalloids'? Which are the triels? So many questions! In this stimulating and innovative book, the Reader will be taken on a voyage from the past to the present to the future of the Periodic Table. This book is unique. This book is readable. This book is thought-provoking. It is a multi-dimensional examination of patterns and trends among the chemical elements. Every reader will discover something about the chemical elements which will provoke thought and a new appreciation as to how the elements relate together.

Past Present and Future

In Past, Present, and Future, Asimov has culled the best of his essays (some of which appear here for the first time) to form a fascinating journey through the world of astronomy, nuclear power, medicine, physics, history, music, film, politics, and other popular subjects. Our preeminent popularizer of science, Asimov takes on many of today's most discussed issues here - Star Wars, the Chernobyl disaster, genetic engineering, the creationism/evolution debate - with a flair, verve, and mastery that have won him innumerable readers. But he also includes many essays written in a personal vein, giving us disarmingly humorous accounts of his triple-bypass surgery and his "Hollywood Non-Career." An entertaining look at Asimov's committment to living in New York City (which he calls "Paradise") is afforded in "I Love New York." On a grand tour of the years ahead, in chapters like "Living on the Moon," "2084," "Should We Fear the Computer?" and "The New Learning," we are shown a future that is thrilling, fearsome, and, as the author insists, our present responsibility. Destined to take its place on the shelves of every Asimov fan, Past, Present, and Future is at once rational, argumentative, informal, and charming.

Diamond, as well as being a precious gem, is a versatile material par excellence. No other material comes anywhere near to matching its properties, which are both extreme, and also expressed in rare combinations. However, natural diamonds, and those synthesised under high sandpressure temperatures, are too expensive or small for many technological applications. These limitations can be overcome by using large-area diamond coatings; chemically bonded to inexpensive non-diamond surfaces. The consequent economic advantages provide the driving force for much diamond-related research and technology. This monograph deals with the past, present and future of diamond thin films. It details their methods of preparation and characterisation, and the mechanisms of nucleation, growth and epitaxy of CVD diamond. Reactor-scale modelling, in situ diagnostics and the processing of diamond films are other important topics that are covered. Expected applications, recent developments and new ideas in the field concluding the monograph.In the near future, applications featuring diamond parts may well grow into whole new industries, with their associated production facilities, supply chains and job opportunities; thereby benefiting society in general. It is therefore in the interests of scientists and engineers working in almost any branch of industry to become familiar with the key concepts and techniques in diamond-coating.

The topic of diffusion science becomes more and more important: this collection of timely papers is divided into seven chapters. The first three are dedicated to macroscopic and microscopic theories of diffusion. Chapter 4 is dedicated to diffusion in nanomaterials, while chapter 5 is devoted to the topic of diffusion along grain and interphase boundaries. This second topic is, of course, not new: it has been discussed for many years, but new themes have evolved in recent times in connection with segregation and stress effects upon grain-boundary diffusion. Both effects become more and more influential in the case of nanomaterials. This is because the fraction of intercrystalline boundaries, and the magnitudes of property gradients (including stress) attain critical values; due to the small sizes of the grains and particles. Chapter 6 deals with grain-boundary phase transitions; especially wetting and liquid penetration. This topic is attracting increased attention both because of its numerous applications and because it offers the opportunity to take a fresh look at the problems of non-equilibrium boundaries and the thermodynamics and kinetics of phase transitions in non-equilibrium systems. One of the hottest topics is the transition from diffusion based upon random walks (in systems close to equilibrium) to directed flows of interface penetration processes (when far from equilibrium). Finally, in chapter 6, the problems of new materials design are discussed, with diffusion as an aid to their testing. This volume will therefore be essential reading matter for anyone who has to deal with the new field of nanomaterial technology.

Adaptation and adaptability are central issues in human population biology and biological anthropology. They are the processes by which relationships between humans and their environments are established and maintained. This volume charts developments in the study of human adaptation andadaptability at the population level in both theoretical and methodological terms. It represents a unique evaluation by the leading researchers in the field, offers a unique review of adaptability studies, and it identifies future directions for the study of human population biology in a changingworld.
