Materials for Sustainable Energy Applications Book Excerpt:

The impending energy crisis brought on by the running out of finite and non-homogenously distributed fossil fuel reserves and the worldwide increase in energy demand has prompted vast research in the development of sustainable energy technologies in the last few decades. However, the efficiency of most of these new technologies is relatively small and therefore it needs to be increased to eventually replace conventional technologies based on fossil fuels. The required efficiency increase primarily relies on the ability to improve the performance of the functional materials which are at the heart of these technologies. The purpose of this book is to give a unified and comprehensive presentation of the fundamentals and the use and design of novel materials for efficient sustainable energy applications, such as conversion, storage, transmission, and consumption. The book presents general coverage of the use and design of advanced materials for sustainable energy applications. Thus, the book addresses all the relevant aspects, such as materials for energy conversion, storage, transmission, and consumption.

Synthesis and Characterization of Ferroelectrics Book Excerpt:

The Special Issue on “Synthesis and Characterization of Ferroelectrics” reports on several physical properties of ferroelectric materials and their technological aspects. Different substitution mechanisms provide ideas toward future improvement of lead-free (Ba,Ca)(Zr,Ti)O3 piezoelectric ceramics, including the electrocaloric effect, fluorescence, and energy storage. It is established that axial and radial element segregation differently influences electrical properties of 0.68Pb(Mg1/3Nb2/3)0.32PbTiO3 (PMN-32PT for short) single crystals. While the electrical properties along the axial direction strongly depend on the PbTiO3 content, the electrical properties along the axial direction are mainly determined by the ratio of Nb and Mg. On the other hand, Fe-substitution of PMN-32PT crystals lead to an enhancement of the coercive field due to wall pinning induced by charged defect dipoles. It is also found, that capacitors based on Pt/Na0.5Bi0.5TiO3/La0.5Sr0.5CoO3 thin films display good fatigue resistance and retention. Another lead-free thin film capacitor fabricated from Ba0.3Sr0.7Zr0.18Ti0.82 features a low leakage current density and high breakdown strength. Such capacitors are essential for energy storage. Furthermore, an enhanced electrocaloric effect on 0.73Pb(Mg1/3Nb2/3)0.27PbTiO3 single crystals is demonstrated. This effect is promising for novel solid-state cooling systems.

Electrocaloric Materials Book Excerpt:

Since the 1997 Kyoto protocol of reduction of greenhouse gas emissions, the development of novel refrigerators has been a priority within the scientific community. Although magnetocaloric materials are promising candidates, they still need a large magnetic field to induce a giant ΔT as well as powerful and costly magnets. However, in electrocaloric materials (ECMs) a temperature change may be achieved by applying or removing an electric field. Since a giant electrocaloric effect on ferroelectric thin films was reported in Science in 2006, researchers have been inspired to explore such effect in different ferroelectric thin films. This book reviews electrocaloric effects observed in bulk materials as well as recent promising advances in thin films, with special emphasis on the ferroelectric, antiferroelectric and relaxor nature of ECMs. It reports a number of considerations about the future of ECMs as a means of achieving an efficient, ecologically sustainable and low cost refrigerator.
