The authors of this book discuss the latest advances in materials science research. The chapters include a discussion on a mathematical model used to study the behavior of piezoelectric materials and its applications in energy harvesting; the highly reactive etchant gas, chlorine trifluoride, and its applications relating to the silicon carbide (SiC) device process; the rheological properties and structure of poly(vinyl chloride)(PVC)/plasticizer systems; a comprehensive review of ultrafine grained TiNi-based SMAs presented in terms of processing techniques, microstructure evolution, thermo-mechanical properties, biocompatibility and applications; and a chapter on the properties of silk/lyocell blended fabrics and the applications of selected functional finishes.
