This book provides readers with the latest developments in materials science research. Chapter One reviews the advances achieved over the last three years by exploiting photo-induced polymerization processes for the obtainment of functional (and often nanostructured) coatings. Chapter Two analyzes superalloy machining. Chapter Three examines a mechanistic exposure of welded Ni-Mo-Cr-Fe alloys in coal gasification syngas plants for morphological and microstructural examination and corrosion mechanism study. Chapter Four discusses atomistic investigations of ion migration in electroactive polymers. Chapter Five focuses on the property and electron shift kinetics of glassy carbon electrodes, and explores biosensor technology that bred diverse trends in detecting heavy metal ions with the adoption of glassy carbon electrode. Chapter Six provides a review of studies regarding antioxidant reaction mechanisms and their electroanalytical applications in glassy carbon electrodes. Chapter Seven investigates the effect of A-site and B-site isovalent doping in Bismuth Titanate ceramics on its dielectric and ferroelectric properties. Chapter Eight concludes with the current progress in the synthesis and luminescence properties of doped Bismuth complex oxides.
