Sommario/riassunto

Polystyrene is a common thermoplastic polymer made from the aromatic monomer styrene with good formability. It is widely used in automotive, electrical and electronic connector systems. This book presents current research in the study of polystyrene, including polystyrene attrition during chemical engineering processes; the biodegradability of polystyrene; the role of adhesion mechanisms of particles on modified polypropylene; direct fluorination of polystyrene; the applications of polystyrene into various sensing platforms; electrospun polystyrene fibres and superhydrophobic surfaces and the synthesis of end-functionalised syndiotactic polystyrene.

Sommario/riassunto

Maritime Piracy is now a pressing global issue, and this work seeks to provide a concise and informative introduction to the area. Never truly having receded into a romanticized past, seaborne banditry's rapid growth was stimulated by low risks and increasingly high rewards. Currently, obsolete, incomplete and complicating structures and norms of governance, together with advances in technology, enable a lucrative business model for pirates, as they effectively operate with impunity and claim increasing ransoms. ?Beginning with an overview and historical development of
