Although in nature the vast majority of polymers are condensation polymers, much publicity has been focused on functionalized vinyl polymers. Functional Condensation Polymers fulfills the need to explore these polymers which form an increasingly important and diverse foundation in the search for new materials in the twentyfirst century. Some of the advantages condensation polymers hold over vinyl polymers include offering different kinds of binding sites, their ability to be made biodegradable, and their different reactivities with various reagents under diverse reaction conditions. They also offer better tailoring of end-products, different tendencies (such as fiber formation), and different physical and chemical properties. Some of the main areas emphasized include dendrimers, control release of drugs, nanostructure materials, controlled biomedical recognition, and controllable electrolyte and electrical properties.
Landslides are one of the most dangerous geomorphological processes, responsible for losses of human lives and damages to structures, infrastructures, cultural and natural heritage. During the Anthropocene, impacts of human activity on the environment, including recent climate changes, have caused deep alterations to the natural evolution of surficial geologic processes, causing a progressive increase in in the occurrence of landslides. The goal of this Research Topic is to provide an updated overview of the progress in the field of landslide research, covering all the aspects related to the geological event: geomorphological characterization and understanding of triggering and predisposing factors, new technologies applied to the study of evolution of slope phenomena, new methodologies to foresee and mitigate landslide hazards.
The fully up-dated edition of the two-volume work covers both the theoretical foundation as well as the practical aspects. A strong insight in driving a chemical reaction is crucial for a deeper understanding of new potential technologies. New procedures for warranty of safety and green principles are discussed. Vol. 1: Fundamentals.
Like its three successful predecessors, 'Organic Synthesis Highlights IV' allows an exciting yet brief survey of modern synthetic methods. More than 40 articles - short, precise and topical - give an overview of the most recent developments and trends in the field. Readers will learn about the key synthetic strategies, new effective methods in enantioselective catalysis, transition metal catalyzed reactions and stereoselective synthesis and applications for the synthesis of natural and non-natural products that are important for their daily work. Much emphasis is placed on referencing in order to make the primary literature easily accessible. Prof. H.-G. Schmalz carefully selected the contributions with a view to creating an up-to-date and critical survey of the current state of the art in organic synthesis
A much-needed overview of the state of the art of hyperbranched polymers The last two decades have seen a surge of interest in hyperbranched polymers due to their ease of synthesis on a large scale and their promising applications in diverse fields, from medicine to nanotechnology. Written by leading scientists in academia and industry, this book provides for the first time a comprehensive overview of the topic, bringing together in one complete volume a wealth of information previously available only in articles scattered across the literature. Drawing on their work at the cutting edge of this dynamic area of research, the authors cover everything readers need to know about hyperbranched po...

During the last two decades silicon-containing dendritic polymers have become one of the fastest growing areas of development in polymer science. The eruption of interest in these new polymers stems from their unprecedented molecular architecture, unique resulting properties and the realization that they represent ideal building blocks for chemical nanotechnology. This is the first book to solely focus on silicon-containing dendritic polymers. The contributions of those experts who originally introduced each field or played a major role in its progress are reported. The developments in all major areas of this field are presented from their origins to the present. It is anticipated that this text will become an invaluable guide and vanguard of reference for experienced scientists interested in the fields of polymer and material science, synthetic chemistry, and nanotechnology. It will also serve advanced graduate students either as a source of creative inspiration or as a textbook for appropriate courses.
Detailed analyses of regional myocardial blood flow, function, metabolism and morphology in ischemic and reperfused myocardium have led to the identifi cation of important phenomena, i. e. , myocardial hibernation, myocardial stun ning and ischemic preconditioning. Both the hibernating and the stunned myocardium characterize viable though dysfunctional as distinguished from necrotic tissue. With the advent of reperfusion procedures, the distinction between reversibly injured, hypofunctional myocardium from irreversibly injured, hypofunctional myocardium is of utmost clinical importance. The pathophysiological distinction of hibernating and stunned myocardium is con troversial, but reperfusio...
Endoscopic ultrasound (EUS) is now considered one of the most essential and cost-effective techniques in the assessment of a wide range of gastrointestinal diseases. A remarkably versatile, minimally invasive procedure, it also calls for a high level of anatomic knowledge and technical prowess. This revised and updated lavishly illustrated volume -- a textbook and atlas in one -- offers medical professionals the most comprehensive overview of EUS available, as well as a wealth of valuable insights from leaders in the field.Features:More than 1000 high-quality imagesLogical, easy-to-use structure, including the requisite anatomy and pathologyStrategies for selecting patients and procedures, i...
The progress in polymer science is revealed in the chapters of Polymer Science: A Comprehensive Reference, Ten Volume Set. In Volume 1, this is reflected in the improved understanding of the properties of polymers in solution, in bulk and in confined situations such as in thin films. Volume 2 addresses new characterization techniques, such as high resolution optical microscopy, scanning probe microscopy and other procedures for surface and interface characterization. Volume 3 presents the great progress achieved in precise synthetic polymerization techniques for vinyl monomers to control macromolecular architecture: the development of metallocene and post-metallocene catalysis for olefin pol...
