One-dimensional semiconducting materials are expected to produce highly-efficient electronic components due to their extraordinary characteristics in applications like nanoscale electronics, biology, optoelectronics, and energy storage. Moreover, complex semiconducting materials have also been developed from nanowires using epitaxial growth mechanisms. The current application areas of nanowires include high-speed transistors, nanoelectronics, chemical- and biosensors, and LEDs (light-emitting diodes) with little power consumption. Concerns for the synthesis of these devices include inferior mobility and optical characteristics of nanomaterials materials. This book offers a thorough understanding of recent developments in synthesizing nanowires for constructing various types of electronic components. Especially, the book reviews the uses of nanowires in sensors, detectors, energy storage, circuits, and energy conversion, etc. Growth approaches of various types of nanowires are also discoursed along with the discussion of their electronic applications. Therefore, this book can be used as a ready reference by researchers, students, and teachers in the field of nanotechnology and electronics.

A very hot topic at the 2010 AASLD meeting, hepatic encephalopathy is being brought to the Clinics in Liver Disease for the very first time by top experts, Dr. Mullen and Dr. Prakash. Authors have written articles that fully discuss the clinical aspects of hepatic encephalopathy (HE). Articles presented include History, Nomenclature and Classification; Theories involved in the pathogenesis of HE; Clinical Assessment and utility of clinical scales for semi-quantification of Overt HE; Assessment of Minimal HE( with emphasis on computerized psychometric tests); Brain Imaging and HE; Management of Overt HE; Management of Minimal HE; Nutritional Interventions for HE; TIPS and HE; Liver Transplantation and Reversibility of HE; Minimal HE and Driving; and HE and Quality of Life.
