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 the thermal conductivity of ceramics; recent advances in tin dioxide materials; dental ceramic and metal surface treatment for bonding; characteristics and thermal properties of nitrocellulose in propellants; application of electrochromic, electroluminescent and photovoltaic devices and polycrystalline silicon thin films.
