This is the first book that presents a comprehensive introduction to and overview of electro-magnetic tissue property imaging techniques using MRI, focusing on Magnetic Resonance Electrical Impedance Tomography (MREIT), Electrical Properties Tomography (EPT) and Quantitative Susceptibility Mapping (QSM). The contrast information from these novel imaging modalities is unique since there is currently no other method to reconstruct high-resolution images of the electro-magnetic tissue properties including electrical conductivity, permittivity, and magnetic susceptibility. These three imaging modalities are based on Maxwell's equations and MRI data acquisition techniques. They are expanding MRI's ability to provide new contrast information on tissue structures and functions.To facilitate further technical progress, the book provides in-depth descriptions of the most updated research outcomes, including underlying physics, mathematical theories and models, measurement techniques, computation issues, and other challenging problems.
This fourth volume of the Supplement Series supplying the Main Volumes of the series "Perfluorohalogenoorgano Compounds of Main Group Elements" (Part 1 to 9) covers the heterocyclic compounds of nitrogen as the last main group element of this series. Compounds of the elements of main group 1 to 4, 6 (without 0), and of P, As, Sb, Bi, and I are presented in the Supplement Volumes 1 to 3. Concept, organization, and selection as to coverage of the material are the same as in the preceeding volumes. Title compounds are either newly synthesized ones or those compounds already referred in the Main Volume Parts 5 and 6 for which new facts have been published. I wish to thank Prof. Dr. Dr. h. c. E. Fluck and his co-workers for their excellent cooperation and many colleagues for providing reprints and patents. One of us (U. Niemann) thanks Philips GmbH Forschungslaboratorium Aachen for generous support. November 1987 Bochum, A.

In this thoroughly innovative work, Hans Ulrich Gumbrecht evokes the year 1926 through explorations of such things as bars, boxing, movie palaces, hunger artists, airplanes, hair gel, bullfighting, film stardom and dance crazes. From the vantage points of Berlin, Buenos Aires, and New York, the reader is allowed multiple itineraries, ultimately becoming immersed in the activities, entertainments, and thought patterns of the citizens of 1926.
The present volume finalizes the coverage of organocopper compounds. A complete formula and ligand index for the Gmelin organocopper series will appear shortly as" Organa copper Compounds" 5. The volume describes mononuclear compounds with ligands bonded by two or more carbon atoms as well as all di- to octanuclear and polymeric compounds. Mononuclear compounds with ligands bonded by one carbon atom have already been described in Vol umes 1 (published in 1985), 2 (published in 1983), and 3 (published in 1986). As structural elucidation in organocopper chemistry gained more attention only in the last few years, the terms "mononuclear", "dinuclear" etc. have been used as explained in "Organocopper Compounds" 1, 1985, pp. 3/4: all compounds are treated with their small est formula unit unless a higher nuclearity has been proved. As a consequence, most of the species treated in volumes 1 to 3 are described there because of insufficient structural information although they are alleged not to be monomeric. This way, many of the better characterized compounds appear in the present volume which is reflected by the more than eighty X-ray structure figures. Generally, nuclearity and structure are not only deter mined by the coordination properties of the ligands, but also by steric requirements, and may therefore widely differ for analogous compounds. For abbreviations and dimensions used throughout this volume, see p. X. Frankfurt am Main, July 1987 Johannes Fussel Remarks on Abbreviations and Dimensions Most compounds and reagents in this volume are presented in tables.
This volume C 1 is the first supplement volume to "Phosphor" C which was published in 1965 and covers the compounds of phosphorus. Starting with the binary species formed between phosphorus and hydrogen, the present volume deals with the neutral mononuclear compounds PH through PH ; the ions featuring the same stoichiometric composition are s covered in separate sections. PH and PH are the major initial gaseous decomposition products of PH and, thus, also 2 J intermediates in many of its gas-phase reactions. Both molecules and their ions have been thoroughly investigated by a variety of modern, high-resolution spectroscopic methods during the last three decades. The coverage of their physical, and mostly molecular, properties re presents the largest part of the first two chapters (PH and ions pp. 2 to 47; PH and ions pp. 47 2 to 111). PH is the only compound described in this volume which is thermally stable under normal J conditions. It is the phosphorus analog of ammonia, but exhibits, however, a quite different chemical behavior towards most elements and compounds. The majority of its physical, and in particular spectroscopic, properties have been determined in great detail since the sixties, partially in regard to spectroscopic investigations of the atmospheres of the outer planets.
Gmelin Handbook of Inorganic and Organometallic Chemistry, presently comprising over 600 volumes, is the most comprehensive collection of chemical and physical data of the elements and their compounds in the world. It is Gmelin's first aim to assemble and systematically classify the research findings scattered throughout the innumerable publications of the international primary literature. This vast amount of information is classified on the basis of the chemical elements, which in itself contributes to "user friendliness". A survey of the contents of the Handbook is given in the Complete Catalog (published every second year, with supplements in between), which can, thus, be very helpful when beginning a search. Access to a specific compound becomes even easier through consultation of the Formula Index volumes. For over three years the Gmelin Formula Index (plus the Complete Catalog entries) has been available as an online database, GFI, from STN. Online searches provide for a most comfortable and fast access to the Handbook. GFI is the first constituent of the complete Gmelin database presently under development. Subscribers to the Handbook are entitled to a 50 % discount when searching GFI online.
This fifth volume of the first supplement supplying the Main Volumes of the series Perfluorohalogenoorgano Compounds of Main Group Elements, Part 1 to 9, starts the treatment of the aliphatic and aromatic perfluorohalogenoorgano compounds of nitrogen. Amines, amides, imines, aminooxy derivatives, nitro- and nitroso compounds as well as azides, hydrazines and diazenes among others are described.
Alloys of Uranium with Alkali Metals, Alkaline Earths, and Elements of Main Groups III and IV. The description of uranium and its compounds, for which the Gmelin Institute has started a series of volumes supplementing the main volume of 1936, follows in its arrangement closely the order chosen for the transuranium volumes. Part A treats "The Element", Part B "The Metal and its Alloys", Part C "The Compounds", Part D "The Chemistry in Solution", and finally Part E "The Coordination Compounds". Part E, "The Coordination Compounds" comprises two volumes which already have been finished and are available - completely written in English. Series A comprises 7 volumes which are all available. Series C will comprise 14 volumes of which only volume 6 is missing. Series D consists of 4 volumes dealing with the chemistry in solution, which already have been finished and are available. The present volume describes the alloys and the intermetallic compounds with the metals of main groups I to IV - those systems with semimetals such as boron and germanium are to be found in corresponding volumes in Uranium C series. In the volume B 2 main emphasis is given to the binary systems. The most frequently investigated systems are uranium-beryllium and uranium-aluminium because of their special scientific (U-Be) and technological (U-Al) importance.
The volume covers alloys and intermetallic compounds of thorium with metals of main groups I to IV as well as related ternary and quaternary alloys. It is the first comprehensive and critical treatise on this topic. The physical properties of ThBe13 have been studied in some detail in order to compare them with those of the heavy fermion compound UBe13. The Th-MG system is of interest for the metallurgy of Mg, since small amounts of Th improve the mechanical strength of Mg and some of its alloys. Detailed information is available on the Th-AI system which is complicated by several intermediate binary phases. Several years ago, this system had attained some technological interest when Th-AI alloys were considered as a potential fuel in thorium breeder reactors. Other Th-main group intermetallic systems are more of scientific than of technological interest. The phase relations in these systems were not elucidated until the 1980s. Numerous ternary alloys consisting of thorium, a metal of main groups I to IV, and a third metal are described. Recent interest has focused on some ternary compounds related to the Th-AI and Th-Sn systems, e.g., THAI8Fe4 and ThSnM (M = Ni, Co, Pt).

The noteworthy and recent increase in interest about GaN originates from the fact that it is a very promising material for applications in high-power and high-frequency electronic and optoelectronic devices. Accordingly, this volume deals primarily with the preparation and properties of this important III-V compound. GaN is a n-type semiconductor but it is possible to also get p-type GaN by doping. Many methods of growing monocrystalline epitaxial films, especially on sapphire, Al2O3, have been developed and are described in detail in the volume. Additional advantages of GaN are its stability at high temperatures and its resistance to most chemicals.
