    • Inglés
    Liquid Metals covers topics about the properties of liquid metals, with emphasis on the microscopic description of the electron states. The book discusses radial distribution function, which is the quantitative way by which the structure of a monatomic fluid may be described, and the scattering of X-rays (or neutrons) from the fluid. The text describes the way by which the forces operating in liquid metals may be qualitatively described; the theory of electron screening in metals; the shielding of a structureless ion core in the Born approximation; and ways by which the structure of the ion core can profoundly influence the shielding. The forces operating between ions in liquid metals; the properties of solid metals; the time-dependent generalization of the structure factor; the dynamics of fluids from inelastic neutron scattering; and the nature of the energy level spectrum of the electrons in a liquid metal are also considered. Students of elementary quantum mechanics and statistical thermodynamics and physicists will find the book invaluable.

    • A. J. Downs + 1 más
    • Inglés
    The Chemistry of Chlorine, Bromine, Iodine and Astatine is a special edition that contains selected sections and addresses the needs of specialists in their respective fields. The text describes the general atomic properties of non-metals, particularly the halogens, as being the perfect series to study, both in physical and chemical terms. The book explains that the combination of the atomic properties implies excellent electronegativity values for the halogen atoms. The text also cites some behavior characteristics of halogens that are irregular, such as chlorine and bromine are similar but differ from fluorine on one side and iodine on the other. The book also compares the general methods of producing chlorine, bromine, or iodine by 1) oxidation of halide derivatives or 2) reduction of compounds of the halogens in positive oxidation states. The text then reviews the application of a complex valence theory that raises difficult questions about the bonding in halogen-oxygen molecules. The book also explains the biological behavior of astatine that accumulates in the liver or in the thyroid gland depending on the method of administration either as a radiocolloid or as a true solution. The book is suitable for molecular biologists and researchers, molecular chemists, and medical researchers.

The volume begins with plenary papers covering topics such as challenges in reactor modeling; bioreactor engineering; the design of reaction systems for specialty organic chemicals. This is followed by papers presented during the eight technical sessions. Technical session A focused on the modeling and control of chemical reactions. Technical session B was devoted to studies on biotechnology. Technical session C covered mixing while Technical session D dealt with special reactor systems and chemicals. The papers in Technical session E examined reactions for emission control and recycling. Technical session F covered the safety aspects of CRE.

    Sources of Ignition: Flammability Characteristics of Chemicals and Products describes the flammability characteristics of substances and deals with the different sources of ignition. Case histories are presented for review and analysis. The book is comprised of six chapters and seven appendices. The introduction gives a basic description of the anatomy of fire and explosions, including the access to fuel and the interaction of oxygen and fuel. A description of the flammable limits of gases, dusts, mists, and mixtures and the method of estimating these follow. The text also explains the flash point of a substance and the method of calculating it, using citations from Fuji and Hermann. The ignition energy of a chemical, as well as how to estimate it using the method of Calcote et al., is also presented. The book explains that autoignition temperature of gases is dependent on different factors, such as time delay, oxygen concentration, and catalyst effects of materials, but may still be estimated citing Zabetakis, 1965 as reference. The formula is given in more detail. Finally, the energy sources for ignition are enumerated as mechanical, electrical, thermal, and chemical. The appendices deal with chemicals, self-heating substances, organic peroxides, substances prone to spontaneous combustions, unstable substances, flammability characteristics of dusts, and a checklist of possible sources of ignition. This book is beneficial to fire safety engineers, firemen, fire prevention maintenance administrators, fire hazard officers, and other personnel whose line of work is in fire safety and prevention.
