Nanowires are nanostructures that have a thickness or diameter constrained to tens of nanometers or less and an unconstrained length. In addition, many different types of nanowires exist, including metallic, semiconducting and insulating. This book presents current research in the study of the properties, synthesis and application of nanowires. Topics discussed include semiconductor nanowires and heterostructure based gas sensors; transport properties of nanostructured materials; nanowire array electrodes in biosensor applications; and, analogies between metallic nanowires and carbon...

In the study of Indian art prior to the Mughal period, portraiture has so far been much neglected, when its existence has not simply been denied. This book is an attempt to reassess this issue, by showing that portraits have existed in great number in early India, since probably the first artistic achievements. Through a close scrutiny of sculpted and (more rarely) painted images brought together with textual and epigraphical references, it aims at highlighting the specificities of Indian portraiture, its relationship with divine images and, consequently, at understanding the development of...
