Materials science encompasses four classes of materials, the study of each of which may be considered a separate field: metals, ceramics, polymers and composites. This volume gathers important research from around the globe in this dynamic field including research on resin-based dental composites; controlled delivery materials; DC art plasma jet; organic potential of rubber tyre wastes; limestone as sorbent for toxic species in energy production; recycling of rubber; fire-induces colour modifications on limestones used as building materials in monuments; poly (vinyl alcohol) ferrogels and electrowinning of precious metals using a modified electrochemical cyclone reactor.
