This book was released on 2012-12-06 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hot-atom chemistry is a unique field of chemistry dealing with highly excited chemical species resulting from nuclear reactions or radioactive decay processes. Modern hot-atom chemistry includes a broad range of disciplines such as fundamental studies from physical chemistry of gas-phase energetic reactions to inorganic solid-state chemistry, as well as recent practical applications in life sciences and energy-related research. In spite of the importance of hot-atom chemistry and its appli cations, its relevance to the other fields of chemistry and related disciplines has attracted little attention and only books and review articles for dedicated hot-atom chemists have been published to date. In this volume, we illustrate the essential aspects of modern hot-atom chemistry for non-specialists, with considerable emphasis on its applications in the related fields. We sincerely hope that this volume can promote mutual understanding and collaboration between hot-atom chemists and researchers in other disciplines. After a brief introduction (Chap. 1) the 2nd chapter gives the non-specialist an idea of experimental techniques commonly used for the production and analysis of hot chemical species. In Chap. 3, we have explained the concepts of hot-atom reac tions in gas, liquid and solid phases with typical examples rather than a comprehensive review of the literature. In view of the current state of accomplishment, the greater part of this chapter is concerned with gas phase studies. Regarding the solid-phase hot atom chemistry, we have confined ourselves only to introducing new concepts and discussing modern aspects.

Available in PDF, EPUB and Kindle. Book excerpt: For 75 years the stopping of energetic ions in matter has been a subject of great theoretical and experimental interest. The theoretical treatment of the stopping of ions in matter is largely due to the work of Bohr, 1-3 Bethe,4-6 Bloch,7. s and Lindhard,9-12 and it has been reviewed by Bohr,3 Fano,13 17 20 Jackson,14 Sigmund,15 Ahlen,16 and Ziegler et al. - Soon after the discovery of energetic particle emission from radioactive materials, there was interest in how these corpuscles were slowed down in traversing matter. In 1900, Marie Curie stated 21 the hypothesis that Hies rayons alpha sont des projectiles materiels susceptibles de perdre de leur vitesse en travers ant la matiere." Early attempts to evaluate this were incon clusive for there was not yet an accurate proposed model of the atom. Enough experimental evidence was collected in the next decade to make stopping power theory one of the central concerns of those attempting to develop an atomic model. J.J. Thomson, director of the prestigious Cavendish Laboratory, and Niels Bohr, a fresh postdoctoral scientist at Rutherford's Manchester Laboratory, both published almost simultaneously22. 23 an analysis of the stopping of charged particles by matter, and each contained many of their divergent ideas on the model of an atom. Thomson ignored in his paper the Rutherford alpha-particle scattering 24 experiment of a year before. But the nuclear atom with a heavy positively 25 charged core was the basis of Bohr's ideas.

Download or read book Properties and Interactions of Interplanetary Dust written by L. Giese and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Investigation of the interplanetary dust cloud is characterized by contributions from quite different methods and fields, such as research on zodiacal light, meteors, micrometeoroids, asteroids, and comets. Since the earth's environment and interplanetary space became accessible to space vehicles these interrelations are clearly evident and extremely useful. Space measurements by micrometeoroid detectors, for example, provide individual and eventually detailed information on impact events, which however are limited in number and therefore restricted in statistical significance. On the other hand, zodiacal light measurements involve scattered light from many particles and therefore provide global information about the average values of physical properties and spatial distribution of interplanetary grains. Additional knowledge stems from lunar samples and from dust collections in the atmosphere and in deep sea sediments. All these sources of complementary information must be put together into a synoptical synthesis. This also has to take into account dynamical aspects and the results of laboratory investigations concerning physical properties of small grains. Such considerable effort is not merely an academic exercise for a few specialists interested in the solar dust cloud. Since this same cloud exclusively allows direct in-situ acess to investigate extraterrestrial dust particles over a wide range of sizes and materials, it provides valuable information for realistic treatment of dust phenomena in other remote cosmic regions such as in dense molecular clouds, circumstellar dust shells, and even protostellar or protoplanetary systems.

Download or read book Th Thorium written by Robert G. Behrens and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volume describes the general properties of the thorium atom and ions, the thermodynamics of its compounds and solutions, the behavior of solutions and solid com pounds under the influence of its own radiation as well as an external radiation field, and spectroscopic data in great detail. The different chapters are of special interest to scientists who work in these fields, and also in the corresponding fields of other elements. In some special fields there exists a detailed knowledge of this radioelement whereas in other fields, such as M6Bbauer spectra, lower oxidation states, or radiation stability, there are large gaps. Due to the fact that the significance 23 of thorium as a breeder fuel ( 2"fh to be converted to fissile 233U after thermal neutron capture) has decreased within the last decade, the behavior of thorium is not as yet so thoroughly investigated as the heavier radioactive element uranium. Many of these data, however, are not only of academic interest, e.g., the knowledge of atomic spectra is needed for some analytical methods, especially in the trace concentration region. Due to the noble gaS-like electronic configuration of the tetravalent ion, there are no absorption bands in the visible region so that in general spectra and data are very scarce. This volume is a very detailed and critically reviewed compilation, written by experts from the Federal Republic of Germany, Belgium, and the United States.
