The well documented increase in the use of high performance composites as structural materials in aerospace components is continuously raising the demands in terms of dynamic performance, structural integrity, reliable life monitoring systems and adaptive actuating abilities. Current technologies address the above issues separately; material property tailoring and custom design practices aim to the enhancement of dynamic and damage tolerance characteristics, whereas life monitoring and actuation is performed with embedded sensors that may be detrimental to the structural integrity of the component. This publication explores the unique properties of carbon nanotubes (CNT) as an additive in the matrix of Fibre Reinforced Plastics (FRP), for producing structural composites with improved mechanical performance as well as sensing/actuating capabilities. The successful combination of the CNT properties and existing sensing actuating technologies leads to the realization of a multifunctional FRP structure. The current volume presents the state of the art research in this field. The contributions cover all the aspects of the novel composite systems, i.e. modeling from nano to macro scale, enhancement of structural efficiency, dispersion and manufacturing, integral health monitoring abilities, Raman monitoring, as well as the capabilities that ordered carbon nanotube arrays offer in terms of sensing and/or actuating in aerospace composites.

Smart/intelligent systems is a primary technology for present and future applications in areas ranging from everyday life to aerospace missions, from civil to military environments, from robots to information technology. Smart materials are the critical foundation for high-performance smart devices, and smart devices are fundamental components for smart systems. The three cannot be separated. This book bridges the fields of smart materials, sensing and actuating devices, and intelligent systems, and provides an opportunity for researchers from all three arenas to channel information into a coherent, interdisciplinary community. Topics include: piezoelectric actuators; novel devices and systems; shape memory alloys and magnetostrictive devices; nanometer-scale processing and properties; piezoelectric materials; sensor materials and devices; and electroactive polymer actuators.

Recent advances in array-based detectors and imaging technologies have provided high throughput systems that can operate within a substantially reduced timeframe and other techniques that can detect multiple contaminants at one time. These technologies are revolutionary in terms of food safety assessment in manufacturing, and will also have a significant impact on areas such as public health and food defence. This book summarizes the latest research and applications of sensor technologies for online and high throughput screening of food. The book first introduces high throughput screening strategies and technology platforms, and discusses key issues in sample collection and preparation. The subsequent chapters are then grouped into four sections: Part I reviews biorecognition techniques; Part II covers the use of optical biosensors and hyperspectral imaging in food safety assessment; Part III focuses on electrochemical and mass-based transducers; and finally Part IV deals with the application of these safety assessment technologies in specific food products, including meat and poultry, seafood, fruits and vegetables. - Summarises the latest research on sensor technologies for online and high-throughput screening of food - Covers high-throughput screening and the current and forecast state of rapid contaminant detection technologies - Looks at the use of optical and electrochemical biosensors and hyperspectral imaging in food safety assessment and the application of these technologies in specific food products

Microelectromechanical systems (MEMS) have transitioned from a technology niche to a role of major industrial significance. The worldwide market for MEMS is now approximately $10 billion, and the total value of systems enabled by MEMS is several orders of magnitude higher than this figure. As the market has grown, the material and process sets have broadened and departed from their semiconductor roots. In addition to engineering materials, there is now great interest in integrating multifunctional nanomaterials, smart materials and biomaterials within MEMS/NEMS to enhance functionality, performance and reliability. The opportunities created by this integration have generated a vibrant research community working on new materials and processes. This book reflects the breadth of topics currently under investigation in the field. Novel materials and accompanying processes are discussed, as are more conventional materials and processes. Consistent themes are the need for accurate material property assessment at the relevant length scales and for suitable metrology tools to support the introduction of new materials.
