Book Description
This book guides beginners in the areas of thin film preparation, characterization, and device making, while providing insight into these areas for experts. As chemically deposited metal oxides are currently gaining attention in development of devices such as solar cells, supercapacitors, batteries, sensors, etc., the book illustrates how the chemical deposition route is emerging as a relatively inexpensive, simple, and convenient solution for large area deposition. The advancement in the nanostructured materials for the development of devices is fully discussed.

Book Description
Cathodic electrodeposition was used to prepare thin films of ZnO doped with Cd, from oxygenated KCl electrolyte containing ZnCl 2 and CdCl2 in various molar ratios ranging from 0 mM to 5.0 mM each. Evidence for doping was obtained from X-ray powder diffraction, diffuse reflectance, chronopotentiometry, and X-ray photoelectron spectroscopy data. The Cd-doped ZnO samples showed a superior photoresponse relative to undoped ZnO. Cadmium- and indium-doped ZnO were prepared by combustion synthesis using CdCl2 and InCl3 as dopant precursors along with zinc nitrate and urea as the combustion mixture. The doped samples were compared and contrasted with undoped ZnO using scanning electron microscopy, X-ray powder diffraction, energy-dispersive X-ray analyses and X-ray photoelectron spectroscopy. Diffuse reflectance spectroscopy showed the optical bandgap of ZnO to shrink from 3.14 eV to 3.07 eV and 3.02 eV on Cd- and In-doping respectively. The doped samples showed an improved photoelectrochemical response relative to undoped ZnO over the wavelength range from & sim;300 nm to & sim;450 nm.

Book Description
NANOLUBRICANTS Through the dissemination of the latest advancements in nanolubrication science, this volume addresses the pressing concerns surrounding their economic feasibility, environmental acceptability, sustainability, and overall viability. Lubrication is the lifeblood of machinery and the key to its smooth operation. In the world of mechanics and engineering, the role of lubricants cannot be overstated. They are the unsung heroes that reduce friction between surfaces in contact, thus preventing excessive heat generation during motion. Beyond this primary function, lubricants find their application in diverse areas, including power transmission, foreign object transportation, and the regulation of surface temperature. In recent times, the world has shifted towards sustainable and environmentally-friendly practices, prompting a transition from conventional lubricants to more efficient and eco-conscious alternatives. Among these emerging solutions, nanolubricants have emerged as formidable contenders, reshaping the landscape of lubrication technology. Their adoption not only promises enhanced performance but also carries the added benefit of environmental responsibility through biodegradability. This book delves into the multifaceted realm of nanolubricants, exploring their characterization and application across various domains. From vegetable oil-based lubricants to those incorporating metal and non-metal oxide components, this comprehensive work encompasses nine meticulously curated chapters. A particular focus is placed on the intriguing synergy between nano-dimensionality and the incorporation of metals and metal oxides into vegetable oil-based biodegradable lubricants. The book explores the environmental advantages, progress, and challenges associated with this innovative approach. Furthermore, it delves into the integration of functionalized nanostructured semi-metal-based compounds as lubricant additives in non-edible vegetable oils, paving the way for improved tribological properties. Audience The book is extremely important to industrial practitioners working in mechanical engineering, tribology, wear, tear, friction and lubrication behavior of machinery. Researchers in nanoscience, nanotechnology, materials science, and sustainability subjects, will find this book useful.
