This volume includes six chapters presenting some of the latest research in materials science. Chapter One reviews a few functionalization and characterization techniques for graphene oxide. Chapter Two examines the role of functionalization methods, synergetic polymeric materials, or anchoring of noble metal nanoparticles in increasing the nonlinear optical properties of graphene-based compounds along with explaining physico-chemical mechanisms. Chapter Three presents the main results, conclusions, and limitations issued from studies examining bentonite adsorption performance in sugar juices, molasses decolorization, and apple juice and wine purification and stabilization. Chapter Four describes a reactive co-evaporation process employed for the fabrication of REBCO coated conductors. Chapter Five reports the effect of nano-silica particles on the thermal and mechanical properties of polyurethane foams synthesized from corn starch, glycerol, polyethylene glycol and methylene diphenyl diisocyanate. Finally, Chapter Six gives an overview of different polypyrrole films electrogenerated onto AZ91D Mg alloy.
