Nonlinear Dielectric Phenomena in Complex Liquids
Complex liquids constitute a basic element in modern materials science; their significant features include self-assembly, mesoscale structures, complex dynamics, unusual phases and enormous sensitivity to perturbations. Understanding their nature and properties are a great challenge to modern materials science that demands novel approaches. This book focuses on nonlinear dielectric phenomena, particularly on nonlinear dielectric spectroscopy (NDS), which may be considered a possible successor to broadband dielectric spectroscopy (BDS). NDS phenomena directly coupled to mesoscale heterogeneity fluctuations, so information obtained in this way is basically complementary to BDS tests. The book also discusses the application of NDS in a set of complex liquid systems: glassy liquids, liquid crystals, liquids with critical point phenomena, and bio-relevant liquids. The complementary application of NDS and BDS may allow the discovery of universal patterns for the whole category of complex liquids. Written by specialists in the field of nonlinear dielectric studies, theoreticians and experimentalists, ranging from solid state physics to biophysics, the book is organized so that it can serve as a basic textbook for a non-experienced reader.
Non-Covalent Multi-Porphyrin Assemblies : Synthesis and Properties
This book presents an overview of the synthesis, structure, and properties of molecules obtained by connecting several porphyrins or metalloporphyrins through a variety of chemical linkages. This handsomely produced book gives the reader a broad introduction to this popular and important field. Much of the work encompassed in this area is inspired by the desire to obtain photochemically responsive molecules capable of mimicking various aspects of photosynthesis… As with many edited volumes of this type, there is a certain amount of duplicate coverage of some topics. Also the focus is largely on the methods used to generate the multiporphyrin arrays, and in some cases less attention is given to the properties, other than the structural properties of these arrays.
NMR in Biological Systems : From Molecules to Human
During teaching NMR to students and researchers, we felt the need for a text-book which can cover modern trends in the application of NMR to biological systems. This book caters to the needs of: (i) graduate students who mostly learn such techniques from senior post-docs in the laboratory; (ii) those who are not experts in NMR but wish to understand if a particular problem in animal, plant, medical and pharmaceutical sciences can be answered by NMR; and (iii) those who are experts in chemistry and biochemistry and wish to know how NMR can provide them information on structural or functional aspect of proteins, nucleic acids, cells and tissues, human and plant organs and other biological materials.
NMR - From Spectra to Structures : An Experimental Approach
Nuclear magnetic resonance spectroscopy is one of the most powerful analytical methods. This practice-oriented textbook aims at teaching how NMR experiments should be used to make structural asssignments. The book is intended as a practical guide for students and laboratory personnel, so that the emphasis is on practical rather than on theoretical aspects, which are treated only to the extent necessary to understand the experiments and to interpret the results.The second edition has been expanded to include several other heteronuclei (15N, 19F, 29Si, 77Se, 113Cd, 117Sn/119Sn, 195Pt, 207Pb) and a new chapter on solid state NMR. The problems section has been enlarged and now includes 50 problems.
N-Heterocyclic Carbenes in Transition Metal Catalysis
It was only in the early 1990s that carbenes with the carbene carbon being incorporated in a nitrogen containing heterocycle (N-heterocyclic carbenes or NHCs) were found to be stable enough to be isolated. Since the first report on the application of NHCs as ligands in transition metal catalysis in 1995, NHC have found numerous applications and have been established as a versatile and indispensable class of ligands. For many reactions like metathesis or cross-coupling reactions NHCs have often become the ligands of choice, allowing otherwise difficult transformations. In this book leading experts have surveyed major areas of application of NHC metal complexes in catalysis. The authors have placed a special focus on nickel- and palladium-catalyzed reactions, on applications in metathesis reactions, on oxidation reactions and on the use of chiral NHC-based catalysts. This compilation is rounded out by an introductory chapter and a chapter dealing with synthetic routes to NHC metal complexes.
New Techniques in Solid-State NMR
After the discovery of nuclear magnetic resonance, [1, 2] the new spectroscopy was used for the study of 1 H nuclei in liquids, but then the signal from copper in the receiver coil itself, the first observation of NMR in the solid state, was found.“Wide-line NMR”, named thus because of the line-broadening effects of dipolar interaction and chemical shift anisotropy, was not far behind, and soon led to significant advances through the analysis of spectral lineshapes. Inthis way Richards and Smith [3] demonstrated the presence of H3O+ cations in solid hydrates of strong acids, while Andrew and Eades [4] investigated the details of molecular motion in three solid benzenes. Even now, 50 years later, it is difficult to think of a technique which would provide a more convincing demonstration of the reality of these effects.
New Methodologies and Techniques for a Sustainable Organic Chemistry
Chemical industries have to face the big challenge of finding adequate processes to produce large quantities of new products for which there is a present need, decreasing at the same time both the impact on the environment and the risk of disasters. These issues have led to the establishment of new concepts of sustainable development as affirmed in the Rio Declaration on Environment and Development in the early 90’s and has been the subject of intensive studies in the last two decades. The book addresses this challenge collecting the recent “New Methodologies and Techniques for a Sustainable Organic Chemistry”.
New Frontiers in Polymer Synthesis
It is generally accepted that a new material is often developed by ?nding a new synthesis method of reaction or a new reaction catalyst. Historically, a typical example may be referred to as a Ziegler–Natta catalyst, which has allowed large-scale production of petroleum-based polyole?ns since the middle of the 20th century. New polymer synthesis, therefore, will hopefully lead to creation of new polymer materials in the 21st century. This special issue contributed by three groups focuses on recent advances in polymer synthesis methods, which handle the cutting-edge aspects of the advanced technology.
