The focus of this volume is the microstructures and related aspects of HTS and thus it forms the sequel (or the Part-II) to the earlier Volume 28 of the book series, which also had the microstructures as its mainstay. The chapters comprising the present volume bring out a host of fresh insights into the growth morphology, defect structures and the structure property relationships in various HTS systems. Closely related to the problem of microstructures is the important issue of the damage mechanics involved in the sample processing, which also forms one of the chapters of this volume. Given its interdisciplinary premise that 'Studies of High Temperature Superconductors: is aimed at professional scientists and engineers, as well as graduate students of physics, chemistry, materials science, solid state electronics and engineering'.
