The discovery of superconductivity in copper oxide perovskite (1) has opened a
new era of research in superconducting materials. This class of materials not only
show high-temperature superconductivity but also show properties that are different
from classical superconductors. This offers a great challenge to understanding
the basic phenomenon that causes superconductivity in these materials and to developing
the appropriate preparation methods so that these can be exploited for a
wide range of applications.
This book contains a collection of works intended to study theoretical and experimental aspects of superconductivity. Here you will find interesting reports on low-Tc superconductors (materials with Tc 30 K). Certainly this book will be useful to encourage further experimental and theoretical researches in superconducting materials
Cáp (highHTS) dẫn so với truyền đây giảm điện, phí siêu dẫn nhiệt độ cao temperature superconductor – có khả năng truyền điện cao gấp 10 lần các loại cáp điện thống. Cáp HTS giờ đã sẵn sàng để giúp tắc nghẽn hệ thống đồng thời giảm chi lắp đặt và vận hành.
In contrast to our previous study (Barth & Marx, 2008) dealing with a currently decreasing
research field (high-temperature superconductors) we analyzed here a topic which has
raised a strongly increasing interest among researchers: research activities around carbon
nanotubes (CNTs or NTs). Carbon nanotubes (often named only nanotubes) are graphite
sheets rolled up into cylinders with diameters of the order of a few nanometers and up to
some millimeters in length with at least one end capped with a hemisphere of the fullerene
Advanced Materials and Technologies
High-temperature superconductors (HTS), ferroelectrics, micromachining or microelectromechanical systems (MEMS), hybrid or monolithic microwave integrated circuits (MMIC), active filters, photonic bandgap (PBG) materials/structures, and low-temperature cofired ceramics (LTCC) are among recent advanced materials and technologies that have stimulated the rapid development of new microstrip and other filters.
