Mme. Curie discovered polonium as a part of her doctoral thesis research. Polonium was the first element to be discovered solely because of its inherent radioactivity. Because there was no knowledge of polonium's chemical properties, the separation steps were followed using only the increase in the specific radioactivity. The first Gmelin Polonium volume, edited in 1941, shows how little was known about polonium for a long time. More detailed investigations on this element were performed only after World War II when the handling of large quantities of highly radioactive nuclides had been developed. Most information on this heaviest Main Group VI element comes from investigations on the tracer scale, especially data that describe its behavior in solution. On the other hand, many solid compounds, such as halides, oxides, and metal polonides as well as the metal itself, are produced in weighable amounts so that structural data are also available. However, these data are far from complete so there is a wide-open field for future research, especially by using the newly developed ultramicrotechniques for preparation and identification of radioactive compounds in the nano- to microgram range. The present volume of the Gmelin Handbook, Polonium Suppl. Vol. 1, gives a very clear, critical, and updated picture of the different aspects of the behavior of polonium - from chemical and physical properties to production, from the nuclear properties of the 29 isotopes to its biological and environmental behavior, and finally to the use of polonium in a variety of applications. Because of the interest in this element has decreased markedly in recent years (apart from its environmental behavior), this volume will be a special and unique source for polonium information for a long time. It also clearly shows that large gaps in our knowledge of this rare natural radioelement still exist. Consequently the volume can serve as a guide to future research initiatives.

The Chemistry of the Actinide and Transactinide Elements is a contemporary and definitive compilation of chemical properties of all of the actinide elements, especially of the technologically important elements uranium and plutonium, as well as the transactinide elements. In addition to the comprehensive treatment of the chemical properties of each element, ion, and compound from atomic number 89 (actinium) through to 109 (meitnerium), this multi-volume work has specialized and definitive chapters on electronic theory, optical and laser fluorescence spectroscopy, X-ray absorption spectroscopy, organoactinide chemistry, thermodynamics, magnetic properties, the metals, coordination chemistry, separations, and trace analysis. Several chapters deal with environmental science, safe handling, and biological interactions of the actinide elements. The Editors invited teams of authors, who are active practitioners and recognized experts in their specialty, to write each chapter and have endeavoured to provide a balanced and insightful treatment of these fascinating elements at the frontier of the periodic table. Because the field has expanded with new spectroscopic techniques and environmental focus, the work encompasses five volumes, each of which groups chapters on related topics. All chapters represent the current state of research in the chemistry of these elements and related fields.

Hair is a major component of the body's tissue system that contributes to the individual's make up and confers a large degree of personal identity. Apart from its visible façade, hair also has a functional role. It has an unique structure and complex molecular development. The very nature of hair makes it a suitable marker for the prognosis of disease. Hair can also be used to screen for toxins and changes in the diet. However, there are currently no suitable publications available that describe hair in a rational scientific context. This handbook provides an academic approach to hair in health and disease. Divided into five sections the Handbook of Hair in Health and Disease provides an insight into hair growth and loss, molecular and cellular biology of hair, dietary toxicity and pathological history, diseases and treatments of hair, as well as shampoos and conditioners. Unique features of each chapter in this volume include relevant and useful 'Key facts' which highlight interesting or important findings of the specific subjects and 'Summary points' that will give a clear overview of the subjects treated in each chapter. The Handbook of Hair in Health and Disease will be essential to a variety of users, such as trichologists, doctors and nurses and all those interested or working within the area of hair health. This includes nutritionists and dieticians, scientific beauticians, health workers and practitioners, college and university lecturers and undergraduate and graduate students.
