This book covers whole aspects of the sulfur isologues of amides. Starting from the synthetic methods of thioamides, a range of synthetic applications to the construction of carbon-sulfur and carbon-carbon bonds, to asymmetric reactions, to formation of heterocycles are described. Among the array of thiocarbonyl compounds, thioamides are readily handled in room temperature air. Some of their characteristic features are that the polarity of C=S bonds in thioamides is much smaller than C=O bonds in ordinary amides, that thioamides possess higher HOMO and lower LUMO when compared with those of ordinary amides, and that carbon atoms alpha to the C=S and nitrogen atoms in thioamides are more acidic than those in ordinary amides. Theoretical studies further disclose their features. Thioamides are also used as ligands to a wide variety of metals. Their unique photophysical properties and catalytic activities are described here. Characteristic features of biologically relevant thioamides, e.g., thiopeptides and related compounds, are the final focus of the book.

Density functional theory (DFT) is by now a well-established method for tackling the quantum mechanics of many-body systems. Originally applied to compute properties of atoms and simple molecules, DFT has quickly become a work horse for more complex applications in the chemical and materials sciences. The present set of lectures, spanning the whole range from basic principles to relativistic and time-dependent extensions of the theory, is the ideal introduction for graduate students or nonspecialist researchers wishing to familiarize themselves with both the basic and most advanced techniques in this field.
The PUILS series delivers up-to-date reviews of progress in Ultrafast Intense Laser Science, a newly emerging interdisciplinary research field spanning atomic and molecular physics, molecular science, and optical science, which has been stimulated by the recent developments in ultrafast laser technologies. Each volume compiles peer-reviewed articles authored by researchers at the forefront of each their own subfields of UILS. Every chapter opens with an overview of the topics to be discussed, so that researchers unfamiliar to the subfield, as well as graduate students, can grasp the importance and attractions of the research topic at hand; these are followed by reports of cutting-edge discoveries. This ninth volume covers a broad range of topics from this interdisciplinary research field, focusing on ultrafast molecular responses to an intense laser field, advanced techniques for attosecond pulse generation, atomic and molecular responses to attosecond pulses, photoelectron spectroscopy of atoms and molecules interacting with intense light fields, and attosecond pulse interaction with solid materials.
The book summarizes recent international research and experimental developments regarding fatigue crack growth investigations of rubber materials. It shows the progress in fundamental as well as advanced research of fracture investigation of rubber material under fatigue loading conditions, especially from the experimental point of view. However, some chapters will describe the progress in numerical modeling and physical description of fracture mechanics and cavitation phenomena in rubbers. Initiation and propagation of cracks in rubber materials are dominant phenomena which determine the lifetime of these soft rubber materials and, as a consequence, the lifetime of the corresponding final rubber parts in various fields of application. Recently, these phenomena became of great scientific interest due to the development of new experimental methods, concepts and models. Furthermore, crack phenomena have an extraordinary impact on rubber wear and abrasion of automotive tires; and understanding of crack initiation and growth in rubbers will help to support the growthing number of activities and worldwide efforts of reduction of tire wear losses and abrasion based emissions.
With the recent advent of nanotechnology, research and development in the area of nanostructured catalysts has gained unprecedented prominence. Novel materials with potentially exciting new applications in catalysis are being discovered at a much higher rate than ever before. Innovative tools to fabricate, manipulate, characterize, and evaluate such materials are being developed and expanded. To keep pace with this extremely rapid growth, it is necessary to take a breath from time to time, to critically assess the current knowledge and provide thoughts for future developments. This book represents one of these moments, as a number of prominent scientists in nanostructured catalysts join forces to provide insightful reviews of their areas of expertise; thus, offering an overall picture of the state-of-the art of the field. Nanostructured materials designate an increasing number of materials with designed shapes, surfaces, structures, pore systems, etc. In general, nanostructured catalysts have modified surfaces, including materials whose surfaces have been altered via such techniques as grafting and tethering of organic or organometallic species, or through various deposition procedures including electro, electroless, and vapor deposition, or simple adsorption. Materials with designed regular pore systems, such as zeolites, metallophosphates, periodic mesoporous materials, nanoporous organic, and organometallic materials are also members of the large family of nanostructured materials. These materials are of paramount importance, particularly in catalysis. One of the most distinctive characteristics of this book is the fact that it is all-inclusive, since most of the materialslisted above have been dealt with in a concise and informative manner. With fourteen up-to-date reports on the design, synthesis, and catalytic properties of nanostructured materials, this book sets the stage for things to come in this area. The development of novel catalysts, taking advantage of the many interesting attributes of periodic nanoporous materials, and the discovery of innovative materials, such as polymer- silica nanocomposites and confined nanoparticles, are some of the leading ideas for future work in the increasingly important field of nanostructured catalysts.
Come on a journey into the heart of matter,and enjoy the process!,as a brilliant scientist and entertaining tour guide takes you on a fascinating voyage through the Periodic Kingdom, the world of the elements. The periodic table, your map for this trip, is the most important concept in chemistry. It hangs in classrooms and labs throughout the world, providing support for students, suggesting new avenues of research for professionals, succinctly organizing the whole of chemistry. The one hundred or so elements listed in the table make up everything in the universe, from microscopic organisms to distant planets. Just how does the periodic table help us make sense of the world around us? Using vivid imagery, ingenious analogies, and liberal doses of humour P. W. Atkins answers this question. He shows us that the Periodic Kingdom is a systematic place. Detailing the geography, history and governing institutions of this imaginary landscape, he demonstrates how physical similarities can point to deeper affinities, and how the location of an element can be used to predict its properties. Here's an opportunity to discover a rich kingdom of the imagination kingdom of which our own world is a manifestation.

This thesis demonstrates the novel magnetic functionalities in cyanido-bridged metal assemblies, and as such appeals to readers in the field of materials science. The utilization of octacyanidometalates as building blocks enables the observation of (i) photo-induced magnetization due to a light-induced spin-crossover in an iron octacyanidoniobate-based assembly, (ii) photo-induced magnetization with a two-step spin-crossover behavior in an iron octacyanidoniobate-based material, and (iii) the coexistence of super-ionic conductivity and metamagnetism in a manganese-octacyanoniobate system. These multi-functionalities are achieved by incorporating a spin-crossover moiety or a hydrogen-bonding network into a cyanido-bridged network structure with a strong magnetic interaction. In particular, in light-induced spin-crossover magnets, a magnetically non-ordered state can be altered to a magnetically ordered state by photo-irradiation, which is one of the attractive mechanisms for novel optical switching devices.

To the eyes of a chemist, carbon is certainly one of the most fascinating elements of the periodic table. Basically, the electronic structure and atomic size of carbon enables this element to form a variety of bonds with other elements and, most importantly, with other carbon atoms as weIl. These unique features lead to the amazingly complicated molecular structures we encounter e. g. in life sciences and organic chemistry. Of course, the technical importance of carbon is enormou- but I don't want to carry too many coals to Newcastle. Prom the viewpoint of an astrophysicist or chemist, the significance of carbon lies in the fact that it is the most abundant condensable element in space. Born in the interior of stars, and from there expelled into the interstellar medium, it initiates the formation of simple and complex molecules and of nanoscopic grains. These in turn form huge clouds in space - the birthplace of new stars and planetary systems. The decisive role of carbon in interstellar chemistry is widely accepted and the search for more and more families of interstellar carbon-bearing molecules is a topic of ongoing research. The interdisciplinary aspect of carbon also concerns its various solid forms, in which C and the other closed-cage fullerenes are certainly some of the most popular 60 newcomers.

This book describes state-of-the-art borylation chemistry using copper(I) catalysis. Enantioselective reactions are included to afford a variety of functionalized, complex organoboronate esters, which will find wide application in asymmetric synthesis, drug discovery, and material science. Organoboron compounds are recognized as useful reagents in organic synthesis; therefore, great effort has been devoted to the development of a simple, mild, and efficient method for their preparation in the past several years. However, the synthesis of functionalized organoboron compounds remains a challenging issue because known reactions often require the use of highly reactive organometallic carbon nucleophiles. This book focuses on conceptually new, formal nucleophilic copper(I)-catalyzed borylation reactions with diboron compounds that show high selectivity and excellent functional group compatibility. Theoretical studies based on density functional theory calculations to understand the reaction mechanisms have also been described. Advances in this novel borylation chemistry will allow the rapid and efficient synthesis of complex molecules with potentially interesting properties in combination with the boron functionalization process.
