This book gives a progress report on the many and original contributions of radiation chemistry to the fundamental knowledge of the vast domain of chemical reactions and its applications. Radiation chemistry techniques indeed make it possible to elucidate detailed physicochemical mechanisms in inorganic and organic chemistry (including in space) and in biochemistry. Moreover, this comprehension is applied in materials science to precisely control syntheses by radiation, such as radiopolymerisation, radiografting, speci c treatment of surfaces (textiles, paintings, inks, etc.), synthesis of complex nanomaterials, degradation of environmental pollutants and radioresistance of materials for nuclear reactors. In life sciences, the study of the effects of radiation on biomacromolecules (DNA, proteins, lipids) not only permits the comprehension of normal or pathological biological mechanisms, but also the improvement of our health. In particular, many advances in cancer radiotherapy, in the radioprotection of nuclear workers and the general population, as well as in the treatment of diseases and the radiosterilization of drugs, could be obtained thanks to this research. Abundantly illustrated and written in English by top international specialists who have taken care to render the subjects accessible, this work will greatly interest those curious about a scienti c eld that is new to them and students attracted by the original and multidisciplinary aspects of the eld. At a time when radiation chemistry research is experiencing spectacular development in numerous countries, this book will attract many newcomers to the eld.

Steels are a class of materials with multiple and complicated transformations; this is true even for steels of the basic cutlery industry. A damascus steel is a fascinating subject to study, rich in multiple facets, that appears in a fi rst approach as a composite material artistically exploited. Damacus steel was developed in the first millennium AD in India or Sri-Lanka. Its reputation is related to its exceptional properties and to the moire pattern. A similar damask pattern could be obtained by forge-welding giving rise to controversies. Recent fi ndings allow a better understanding of this pattern formation. This book presents firstly, observations of ancient blade samples examined with modern technologies such as electron microscopy. The features of many typical swords from different periods are discussed: Celtic, Merovingian, Viking and oriental wootz swords, Persian shamshirs, Japanese katana, rapiers etc. In the second part, microstructural observations at different levels of magnifi cation are displayed and their interpretation is discussed in detail, thus revealing the secret of sophisticated forgings. One chapter is devoted to introducing the main transformations undergone by these steels during the forging processes. The book is intended for all those people interested in the history of science and more specifi cally to the metallurgists, to the archaeologists and all the researchers confronted with the problems of the expertise of the vestiges, to the blacksmiths, and to the collectors of valuable artistic blades. Madeleine Durand-Charre has taught structural metallurgy at the Polytechnic Institute of Grenoble and at the University Joseph Fourier of Grenoble. Her research work concerned microstructure formation and determination of phase equilibria. She investigated complex alloys such as superalloys and steels. Her work on vanadium cast irons was awarded the Vanadium Shield in 1989 from the Institute of Metals. She is author of several books and articles in metallurgy.

Glass-ceramics are now commonplace in our daily lives, despite having only been discovered for less than a century. It presents an update on the recent developments concerning the mechanisms of nucleation, crystal growth and phase separation, bringing together theoretical aspects and characterization methods.

This multidisciplinary book is the result of a collective work synthesizing presentations made by various specialists during the CNRS BIODEMAT school, which took place in October 2014 in La Rochelle, France. It is designed for readers of a range of scientific specialties (chemistry, biology, physics...) and examines various industrial problems.
