The present book describes a large variety of different types of chain systems (nanowires), including shorter chains that are artificially produced for instance in break-junction experiments, chains synthesized as guests inside the channels of a host crystal, crystalline chain compounds, organic polymers (synthetic metals), and charge-transfer salts, thus covering an unusual wealth of systems. Both experimental and theoretical studies are discussed. Particular emphasis is put on illustrating the special phenomena that occur in such quasi-one-dimensional systems, and how theoretical and experimental efforts have been used in identifying those properties that are specific for truly one-dimensional systems from those of quasi-one-dimensional systems. Moreover, it is shown that metallic chains can be found in a large range of systems, but also that chains of metals not always are metallic.� Gives a unifying description of very many different phenomena and systems� High-Tc superconductors, conjugated polymers, gold nanowires, carbon nanotubes, chain compounds, and charge-transfer salts are all treated in one volume� Illustrates the very broad range of quasi-one-dimensional systems

This book aims to provide reader an overview of clinical applications of contrast-enhanced ultrasound in hepatic neoplasms diagnosis. Ultrasound images and pathological results of different hepatic neoplasms are introduced in the chapters, including benign liver tumors, malignant liver tumors, hepatic carcinoma, intrahepatic cholangiocarcinoma, rare liver benign and malignant neoplasms, regenerative nodules, inflammatory pseudotumor, parasite liver lesions, and hepatitis peliosis, etc. The combination of ultrasound findings with final histopathological results then discover the potential mechanical of contrast enhancement changes. With the development of ultrasound technology and widely application of ultrasound contrast agents (USCA) in recent decades, contrast-specific imaging modalities have been developed in combination with USCA and a low mechanical index (MI), allowing continuous real-time grey scale imaging. The updated contrast-specific software for liver diseases and hepatic tumors diagnosis has also been described described in detail. With high-resolution contrast ultrasound images during arterial phase, portal venous phase and late phase, author wants to show the whole dynamic wash-in and wash-out process of the different focal liver lesions.This book is an invaluable resource for radiologists, hepatologists and oncologists in their everyday clinical practice.
