Gmelin Si.Silicon Suppl/Pt B Sec 5b (closed) 2
The volume aims to provide the reader with a broad picture of the mechanical properties (density, elastic properties, hardness and wear resistance, strength and related properties, plastic deformation, thermal stress and shock resistance, and mechanical properties of joints) of silicon nitride - one of the important modern, nonoxide ceramic materials. Intrinsic properties of high-purity materials are covered, but more widely detailed are the properties of less-pure technical types of material which contain substantial amounts of additives to aid in the fabrication of dense polycristalline bodies. The volume concludes with chapters on thermal properties (e.g., thermodynamic data of formation, thermodynamic functions, heat capacities, melting, thermal conductivity and thermal diffusivity) and on self-diffusion and heterodiffusion.

N Nitrogen
"Nitrogen" Suppt. Vol. B 1 describes the compounds of nitrogen with noble gases and, in the major part, binary compounds composed of one nitrogen atom and hydrogen. Nitrogen hydrogen compounds with two and more nitrogen atoms are covered in "Nitrogen" Suppt. Vol. 82. There is some information on various nitrogen-noble gas species, to a large extent because of the interest in their bonding behavior. Experimental data have been obtained chiefly for some singly charged cations, particularly those formed by argon Like ArN + and ArNi. The existence of others has only been established by mass spectrometry. The binary compounds of nitrogen and hydrogen comprise NH, NH , NH , NH , the corre 2 4 5 sp...
Binary Species of Silicon and Fluorine
The volume is concerned exclusively with all the binary species formed between the elements silicon and fluorine such as SiF, SiF2, SiF3, SiF4, and Sif62-. Most of the volume, i.e. 144 pages, is devoted to the description of the well known physical and chemical properties of the SiF4 as well as to its preparation. This is followed in length by the report on SiF2 with its interesting chemistry, along with a section on the diatomic radical SiF. Species with fivefold and sixfold coordination of silicon are exemplified by SiF5- and by the well known SiF62-. Interestingly, the detailed models for describing the bonding situation in both ions are still a matter of discussion. While for Si2F6 most of the basic data are known, information on the chemical and physical properties of the higher members of the acylic perfluorosilanes, SinF2n+2, is scarce. All available information on the unstable cyclic perfluorosilanes of composition (SiF2)n and some even more exotic species is also included.
Molecular Environmental Biology
Molecular Environmental Biology is the first book to illustrate molecular biological approaches to major issues in environmental biology. International experts have contributed representative chapters that cover how molecular methods and concepts apply to wildlife management, ecology, pollution control and remediation, and environmental health. Specific topics discussed include the use of molecular techniques in the population biology of wild animals and in the management of fisheries, bioremediation, cloning and characterization of the genes responsible for degradation of PCBs and related environmental pollutants, molecular analysis of aromatic hydrocarbon degradation by soil bacteria, and ...
Environmental Economics and Policy
Environmental Economics and Policy is a best-selling text for environmental economics courses. Offering a policy-oriented approach, it introduces economic theory, empirical fieldwork, and case studies that show how underlying economic principles provided the foundation for environmental policies. Key features include: Introductions to the theory and method of environmental economics, including externalities, benefit-cost analysis, valuation methods, and ecosystem goods and services. Extensive coverage of the major issues including climate change mitigation and adaptation, air and water pollution, and environmental justice. Boxed "Examples" and "Debates" throughout the text, which highlight g...
