Book Synopsis Transition Metal Ions Doped Zno Nanopowders by : B. Babu

Download or read book Transition Metal Ions Doped Zno Nanopowders written by B. Babu. This book was released on 2015-02-16. Available in PDF, EPUB and Kindle. Book excerpt: Intensive research on semiconductor nanomaterials has increased remarkably during the past years due to their unique characteristics. Wide-band gap oxide semiconductors have occupied the forefront because of an increasing need for short wavelength photonic devices, high-power, high-frequency electronic devices. Doping with proper metal elements via introducing acceptor or donor in host material is an effective approach to tune the materials with requisite properties. Among different magnetic semiconductor materials, 3d transition metal doped ZnO has received maximum attention due to the observation of room temperature ferromagnetism with suitable magnetic dopant ions. Therefore, selection of proper doping element in ZnO has become an important route for enhancing and controlling electrical, optical and magnetic performances of nanomaterials. The objective of the present investigation is to synthesis, structural, spectroscopic and magnetic properties of transition metal ions doped ZnO nanopowders by solid state reaction with sonochemical assistance. The synthesized powders are characterized by XRD, SEM, Optical absorption, PL, FT-IR, EPR and VSM techniques.

Book Synopsis Metal Oxides in Supercapacitors by : Deepak P. Dubal

Download or read book Metal Oxides in Supercapacitors written by Deepak P. Dubal. This book was released on 2017-07-10. Available in PDF, EPUB and Kindle. Book excerpt: Metal Oxides in Supercapacitors addresses the fundamentals of metal oxide-based supercapacitors and provides an overview of recent advancements in this area. Metal oxides attract most of the materials scientists use due to their excellent physico-chemical properties and stability in electrochemical systems. This justification for the usage of metal oxides as electrode materials in supercapacitors is their potential to attain high capacitance at low cost. After providing the principles, the heart of the book discusses recent advances, including: binary metal oxides-based supercapacitors, nanotechnology, ternary metal oxides, polyoxometalates and hybrids. Moreover, the factors affecting the charge storage mechanism of metal oxides are explored in detail. The electrolytes, which are the soul of supercapacitors and a mostly ignored character of investigations, are also exposed in depth, as is the fabrication and design of supercapacitors and their merits and demerits. Lastly, the market status of supercapacitors and a discussion pointing out the future scope and directions of next generation metal oxides based supercapacitors is explored, making this a comprehensive book on the latest, cutting-edge research in the field. - Explores the most recent advances made in metal oxides in supercapacitors - Discusses cutting-edge nanotechnology for supercapacitors - Includes fundamental properties of metal oxides in supercapacitors that can be used to guide and promote technology development - Contains contributions from leading international scientists active in supercapacitor research and manufacturing
