  • Space Charge in HVDC Extruded Insulation: Storage, Effects, and Measurement Methods

    This chapter discusses space-charge storage in HVDC extruded insulation, the relevant manifold effects, and the techniques developed by researchers in order to measure the amount and distribution of space charge stored in the insulation, and the electric field profile associated with such distribution. It reviews the theoretical background of charge injection and transport in insulating polymers. The chapter illustrates the processes that result in space-charge accumulation namely charge generation - via electronic charge injection, field-assisted thermal ionization of impurities, spatially inhomogeneous electric polarization, and steady DC current coupled with a spatially varying ratio ofpermittivity to conductivity. It also reviews the space-charge measurement methods for HVDC extruded insulation. The chapter focuses on the up-to-date developments of the best-suited techniques for measuring space charges in extruded insulation for HVDC cables. It provides a comparison between the best space-charge measurement methods for power cables: pulsed electro acoustic (PEA) versus thermal step method (TSM).

    Cardiac tissue engineering aims at repairing damaged heart muscle and producing human cardiac tissues for application in drug toxicity studies. This book offers a comprehensive overview of the cardiac tissue engineering strategies, including presenting and discussing the various concepts in use, research directions and applications. Essential basic information on the major components in cardiac tissue engineering, namely cell sources and biomaterials, is firstly presented to the readers, followed by a detailed description of their implementation in different strategies, broadly divided to cellular and acellular ones. In cellular approaches, the biomaterials are used to increase cell retention after implantation or as scaffolds when bioengineering the cardiac patch, in vitro. In acellular approaches, the biomaterials are used as ECM replacement for damaged cardiac ECM after MI, or, in combination with growth factors, the biomaterials assume an additional function as a depot for prolong d factor activity for the effective recruitment of repairing cells. The book also presents technological innovations aimed to improve the quality of the cardiac patches, such as bioreactor applications, stimulation patterns and prevascularization. This book could be of interest not only from an educational perspective (i.e. for graduate students), but also for researchers and medical professionals, to offer them fresh views on novel and powerful treatment strategies. We hope that the reader will find a broad spectrum of ideas and possibilities described in this book both interesting and convincing.

  • OLED Materials

    OLED performance is largely dependent upon OLED materials. This chapter describes the classification of OLED materials and typical OLED materials.OLED materials are divided into two types ??? vacuum evaporation type and solution type ??? from a process point of view. Vacuum evaporation materials are usually small molecular materials, while solution type materials contain polymers, dendrimers, and small molecular materials. In addition, materials are also divided into fluorescent materials, phosphorescent materials, and thermally activated delayed fluorescent (TADF) materials in terms of emission mechanisms. From the function point of view, OLED materials can be classified as hole injection material, hole transport material, emission material, host material in emissive layer, electron transport material, electron injection material, charge blocking material, etc.Anode and cathode materials are also important, so this chapter also describes anode and cathode materials.In addition, this chapter describes molecular orientations of organic materials because this also influences OLED characteristics.

  • Micro- and Nanotechnologies to Engineer Bone Regeneration

    In this chapter, selected published articles pertaining to micro- and nanotechnologies for bone tissue engineering are reviewed with a focus on development of scaffolds. Nanoparticles and nanofibers have shown to improve the mechanical properties of biodegradable polymeric implants. Non-union bone fractures are a major health care concern in the United States. One of the most widely used strategies in bone tissue engineering is the use of scaffolds for temporary structural support. Scaffolds are porous biomaterials and play a central role in tissue engineering approaches by guiding cell proliferation and assisting the exchange of nutrients and waste. Scaffolds made with micro- and nanoparticles and micro- and nanofibers show much promise as they impart the ability to create scaffolds with appropriate mechanical properties and microenvironment. The chapter discusses micro/nanomaterials of hydroxyapatite, a variety of synthetic polymers, and silk, and their potential for use as bone tissue engineering scaffolds.

  • Will Composite Nanomaterials Replace Piezoelectric Thin Films for Energy Transduction Applications?

    Semiconducting piezoelectric nanowires (NWs) show significant potential for application in electronic and electromechanical sensors and energy harvesters. In particular, these nanostructures can be used to build composite piezoelectric materials that could offer several advantages when integrated vertically. First, NWs of various lengths opens the possibility to fabricate composite layers thicker than standard thin films (<4 ??m). Second, low???temperature fabrication process make this technology compatible with CMOS devices and with different substrates, such as Si, polymers, plastics, metal foils, and even paper. Third, properties such as piezoelectricity, flexibility, and dielectric constant can be improved in NWs, thereby improving the performance of NW???containing composite materials. Finally, FEM simulations show that composites can provide better performance compared to piezoelectric thin films of the same thickness, and that performance can be improved by operating in compression or flexion modes by the right choice of the dielectric matrix and NW density.
