✏Electrocaloric Materials Book Summary : 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.

✏Chip scale Cooling Devices Based On Electrocaloric Effect Book Summary : The electrocaloric effect (ECE) is a temperature and entropy change of an insulating material when there is an electric field induced polarization change. Recently, giant ECE was discovered in a series of dielectric materials, such as Polyvinylidene fluoride (PVDF) based polymers and ferroelectric ceramics. The ECE induced adiabatic temperature change in these materials can be higher than 10 K which makes them attractive because they provide the unique opportunity to explore and develop solid state cooling devices which are compact while providing high cooling power density and high efficiency compare to other cooling techniques, such as vapor compression refrigeration(VCR), thermoelectric, thermoacoustic, etc. A few ECE refrigerators have been studied in previous publications. However, the performance of those devices are still not so attractive. Besides, most of the existing works are based on simulation, and very few work has prototype demonstration.In this thesis, two types of chip scale ECE based cooling devices with more advanced configurations have been proposed, studied, and experimentally demonstrated. One is named as ElectroCaloric Oscillatory Refrigerator (ECOR), which involves solid-state plates with anisotropic thermal conductivity as regenerators. The low thermal conductivity along the temperature gradient direction can reduce the heat conduction loss thus highly improve the performance of the device. Finite volume simulation shows that the temperature span (Tspan) of the refrigerator can be as large as around 50 K. The volumetric cooling power density Pc and coefficient of performance (COP) of the refrigerator was also studied. The maximum Pc can reach to 9.2 W/cm3, while the COP remains at 6.5, which is about 45% of the Carnot efficiency.A prototype of ECOR was experimentally demonstrated. The EC module with multilayer structure was fabricated with high energy electro irradiated poly(vinylidene fluoride-trifluoroethylene) (P(VDF-TrFE)) copolymer thin film. The regenerators with anisotropic thermal conductivity was realized by cutting thin slits in stainless steel plate and then refilled with epoxy. The testing results show that a maximum value of 6.6 K Tspan was obtained when the device was working at 1 Hz and with an electric field of 100 MV/m.The second proposed device configuration is based on a rotary structure. This refrigerator involves no external regenerators. Instead, the regeneration process is realized by direct heat exchange between EC materials. The 1-D simulation results show that the Tspan of the device is nearly proportional to the number of segments in one ring (Ns), and the ECE induced adiabatic temperature change (Delta TECE). Owing to the absence of external regenerators, the Pc of this device can reach 33 W/cm3. Meanwhile, the COP of the device keeps above 8.5, which is about 60% of Carnot efficiency. 3-D finite element simulation validates the 1-D simulation results. A preliminary prototype was fabricated to demonstrate the proposed concept. About 0.8 K Tspan was obtained across the device when Delta TECE is 0.4 K.Compare with the existing ECE cooling devices, the ECOR device in this thesis involves solid state regenerator with anisotropic thermal conductivity which can highly reduce the conduction heat loss and thus improve the performance of the device. In the rotary cooling device, novel regeneration process is designed so that no external regenerators are required which also highly improve the cooling power density and efficiency of the device. The ideas of both solid state regenerator with anisotropic thermal conductivity, and the novel regeneration process are the main contributions of this thesis and will stimulate the development of high performance ECE cooling devices in the future.

✏Electrocaloric Cooling Book Summary : The electrocaloric effect describes a reversible temperature change in dielectric materials submitted to an applied electric field. Adiabatic polarization raises their temperature, and adiabatic depolarization lowers it, analogous to temperature changes that occur when a gas is compressed or expanded. For refrigerator application, the reverse Brayton cycle is currently the most promising for practical implementation. The electrocaloric effect provides a large material efficiency. However, existing refrigerator prototypes lack from the absence of efficient heat switches for thermal linkage to the load and the heat sink. Cooling power densities of a few W/cm2 and temperature spans in the order of 20 K (in regeneration systems) are achievable at a cycle time of 100 manuscript.

The applied electric field along [001] direction reduces the ferroelectric-ferroelectric phase transition temperatures, but increases the Curie temperatures. The electrocaloric coefficients of tetragonal phase are much larger than that of rhombohedral and monoclinic phase. A negative electrocaloric effect is observed near the MC–T phase transition in 0.69Pb(Mg1/3Nb2/3)O3–0.31PbTiO3 single crystal. The application of a strong enough electric field results in a high adiabatic temperature change over a broad range of temperature. Therefore, it would be useful to construct a solid state cooling cycle over a broad temperature range for practical applications.

✏Materials for Sustainable Energy Applications Book Summary : 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.

✏Oscillating Magneto and Electrocaloric Effects on Bilayer Graphenes Book Summary : Abstract: Recently, the oscillating magnetocaloric effect (OMCE) was proposed and theoretical verified as an intrinsic property of diamagnetic materials; and then it was further optimized considering a monolayer graphene. OMCE biased by an electric field was also deeply investigated, but Joule heating was a problem to be overcome. The present effort thus goes further and analysis of the OMCE of biased bilayer graphene under an electric and magnetic field is carried out. General expressions for the thermodynamic potentials are derived and then the entropy change and the adiabatic temperature change are investigated. We found that the results for bilayer graphenes are very similar to those for monolayer and, in addition, the Joule heating problem could be overcome, since the gate potential is applied between the two layers. Abstract : Highlights: The oscillating magnetocaloric effect of a bilayer graphene is analyzed. The influence of a electric field is also considered. Results for bilayer graphenes are very similar to those for monolayer. There is no Joule heating since the gate potential is applied between the two layers.

✏The Application of Dielectric and Electrocaloric Cooling Devices Based on Dielectric Polymers Book Summary : The objective of my research is to develop energy storage device and electrocaloric cooling device based on dielectric materials. The first part of research work is to develop energy storage capacitor with high energy density by nanocomposite approach based on dipolar polymers. The second part of my research work is to develop electrocaloric effect (ECE) based cooling device.Dielectric constant, dielectric breakdown strength, dielectric loss (at high voltage application, conduction loss is also critical), and operating temperature are critical parameters in dielectric materials and their applications. This thesis investigates innovative approaches to enhance these properties of polymer-based dielectrics.Dielectric polymers are widely used in modern electronics due to the low loss and high breakdown strength. The state-of-art material is biaxially oriented polypropylene (BOPP) which has high breakdown strength (>700 MV/m) and low dielectric loss (0.02%). However, it is limited by its low energy density (2 J/cm3) due to the low dielectric constant (k~2.2) and low working temperature (80 C). In order to raise the dielectric constant K of polymer-based dielectrics and hence improve the energy density, nanocomposites in which high volume loading ( 15 vol%) of high dielectric constant nanofillers (K 1000) is added to a polymer matrix have been widely studied. However, the large dielectric contrast between the nanofillers and polymer matrix and high volume loading of nanofillers result in intensification of local electric fields in the polymer matrix, leading to a large reduction of the dielectric breakdown strength.Recently, Dr. Y Thakur at our group discovered that in dipolar polymer polyetherimide (PEI) (k~3.2), very low volume loading ( 0.5 vol%) of nanofillers can lead to more than 50% increase in the dielectric constant K and remain high breakdown strength. This thesis investigates whether such an approach can be applied to other dipolar polymers with higher dielectric constant, such as polyimide (PI) (k~3.5) and poly (ether methyl ether urea) (PEMEU) (k~4). The results reveal that the nanocomposites based on these amorphous polymers also have large enhancement of dielectric constant. However, the breakdown strength in these nanocomposites cannot be further improved. Moreover, the presence of nanofillers in amorphous polymers does not reduce the conduction loss at high fields, and hence do not enhance the breakdown strength and do not generate a large improvement in the high temperature performance. I investigated semi-crystal polymer poly (arylene ether urea) (PEEU) and discovered that PEEU nanocomposite with very low volume loading (~ 0.2 vol%) of alumina nanoparticles can significantly enhance the energy density, charge/discharge efficiency and breakdown strength at high temperature. Specifically, we show that PEEU nanocomposite with 0.2 vol% of 20 nm size alumina nanofillers increases both the dielectric constant K and breakdown field E over a broad temperature range to 150 oC. The dielectric constant K is raised from K = 4.7 of the base PEEU to 7.4. At 150 oC, the nanocomposite films exhibit a breakdown strength of 600 MV/m, increased from 400 MV/m of the base PEEU films. Moreover, nanofiller at such a low loading also significantly reduces the high field conduction loss and, as a result, the PEEU films deliver a discharged Ue of 5 J/cm3 with a high C/D efficiency (> 90%) at 150 oC.I further investigated how the surface modification affect the dielectric constant of nanocomposite. The results show that the dielectric constant enhancement of the nanocomposite with modified surface is reduced. It demonstrates the enhancement of dielectric constant is related to the elastic coupling between polymer matrix and nanoparticles.For nanocomposite approach, the nanofiller dimension is another critical variable. (i) I studied nanocomposite with 1-D nanofiller and found the enhancement is reduced compared with nanocomposites with 0-D nanoparticles. (ii) Poly-p-phenylene benzobisoxazole (PBO) (k~4.5) nanocomposite with 2D nanosheet is also studied (in collaboration with Dr. Cheng Huang of Suzhou University). The results reveal a very large dielectric enhancement. K ~8.7 (loss ~ 1%) was measured for nanocomposites with 1.8 vol% TiO2 nanosheet loading, which is about 2X of the neat PBO. Among all the known polymers, such a high dielectric constant can only be obtained in ferroelectric polymers (such as Polyvinylidene fluoride (PVDF) based polymers). In contrast to PVDF based polymers, the dielectric response of PBO nanocomposites remain linear under high field (200 MV/m). All the above results demonstrates that nanofillers beyond nanoparticles can generate additional variable to enhance the dielectric performance and the dielectric enhancement is determined by the combination of the polymer matrix (structure) and nanofiller (size and dimension).This thesis also investigated another important application of dielectric material, e.g., the electrocaloric effect (ECE) based cooling. The proposed device is based on a counter-rotating disks structure to achieve internal thermal regeneration, thus eliminates the external regenerators and enhances the efficiency. To demonstrate the concept, a commercial multilayer ceramic capacitor (MLCC) was chosen for the EC elements, which generated an EC temperature change of 0.9 K under 200 V. For the EC cooler with two EC rings, which is the minimum required to form a counter-rotating disks device, and at 5 rpm, the device exhibits a temperature lift between the cold and hot ends which is 3X of the EC temperature change of single EC element, demonstrating the concept.

✏Dielectric and Related Molecular Processes Book Summary : Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued.

✏Electrocaloric Properties of Pb La Zr Ti O3 and BaTiO3 Ceramics Book Summary : The electrocaloric properties of (Pb,La)(Zr,Ti)O3 (PLZT) and BaTiO3 ceramics were investigated by the indirect estimation and direct measurement of temperature-electric field (T-E) hysteresis loops. The measured T-E loops showed a similar shape to strain-electric field (s-E) loops. The adiabatic temperature change ∆T due to electrocaloric effects was estimated from the polarization change of these samples. ∆Ts of 0.58 and 0.36 K were estimated for the (Pb,La)(Zr,Ti)O3 (PLZT)(9.1/65/35) ceramics and BaTiO3 ceramics sintered at 1400°C, respectively. The measured temperature changes ∆Ts in these samples upon the release of the electric field from 30 kV/cm to zero were 0.26 and 0.29 K, respectively.

✏Compact Solid State Cooling Systems Book Summary : BEETIT Project: UCLA is developing a novel solid-state cooling technology to translate a recent scientific discovery of the so-called giant electrocaloric effect into commercially viable compact cooling systems. Traditional air conditioners use noisy, vapor compression systems that include a polluting liquid refrigerant to circulate within the air conditioner, absorb heat, and pump the heat out into the environment. Electrocaloric materials achieve the same result by heating up when placed within an electric field and cooling down when removed--effectively pumping heat out from a cooler to warmer environment. This electrocaloric-based solid state cooling system is quiet and does not use liquid refrigerants. The innovation includes developing nano-structured materials and reliable interfaces for heat exchange. With these innovations and advances in micro/nano-scale manufacturing technologies pioneered by semiconductor companies, UCLA is aiming to extend the performance/reliability of the cooling module.

The present subvolume III/28a contains data on ferroelectric oxides, supplementing III/16a which appeared in 1981. Subvolume III/28b, due in 1990, will cover non-oxides, supplementing III/16b (published in 1982). Reliable data on both pure compounds and solid solutions, published mostly between 1978 and 1986 and some data from the literature up to early 1988 are critically evaluated and included. The dielectric and ferroelectric behaviour, as well as all other properties relevant to the characterization of these substances are presented in tables and figures. About 22,000 references have been surveyed with the aid of a computer. All values are given in SI units. Rapid localization of the required data is facilitated by an alphabetical index of substances and a two-dimensional survey of substances and properties dealt with in both subvolumes III/28a and III/16a.

✏The Nano Micro Interface 2 Volumes Book Summary : Controlling the properties of materials by modifying their composition and by manipulating the arrangement of atoms and molecules is a dream that can be achieved by nanotechnology. As one of the fastest developing and innovative -- as well as well-funded -- fields in science, nanotechnology has already significantly changed the research landscape in chemistry, materials science, and physics, with numerous applications in consumer products, such as sunscreens and water-repellent clothes. It is also thanks to this multidisciplinary field that flat panel displays, highly efficient solar cells, and new biological imaging techniques have become reality. This second, enlarged edition has been fully updated to address the rapid progress made within this field in recent years. Internationally recognized experts provide comprehensive, first-hand information, resulting in an overview of the entire nano-micro world. In so doing, they cover aspects of funding and commercialization, the manufacture and future applications of nanomaterials, the fundamentals of nanostructures leading to macroscale objects as well as the ongoing miniaturization toward the nanoscale domain. Along the way, the authors explain the effects occurring at the nanoscale and the nanotechnological characterization techniques. An additional topic on the role of nanotechnology in energy and mobility covers the challenge of developing materials and devices, such as electrodes and membrane materials for fuel cells and catalysts for sustainable transportation. Also new to this edition are the latest figures for funding, investments, and commercialization prospects, as well as recent research programs and organizations.

✏Advanced Ferroelectricity Book Summary : The field of ferroelectricity has greatly expanded and changed in recent times. In addition to classical organic and inorganic ferroelectrics, new fields and materials, unknown or inactive 20 to 40 years ago, have appeared. They are important for both basic science and applications, and show technological promise for novel multifunctional devices. New fields include multiferroic magnetoelectric systems, where spontaneous polarization and spontaneous magnetizationare allowed to coexist; incommensurate ferroelectrics, where the periodicity of the order parameter is incommensurate to the periodicity of the underlying basic crystal lattice; ferroelectric liquidcrystals; dipolar glasses; relaxor ferroelectrics; ferroelectric thin films; nanoferroelectrics. The book is primarily intended for material scientists working in research or industry. It is also intended for graduate and doctoral students and can be used as a textbook in graduate courses. Finally, it should be useful for anybody interested in following the developments in modern solid state physics.

✏Ferroelectric Devices Book Summary : Updating its bestselling predecessor, Ferroelectric Devices, Second Edition assesses the last decade of developments—and setbacks—in the commercialization of ferroelectricity. Field pioneer and esteemed author Uchino provides insight into why this relatively nascent and interdisciplinary process has failed so far without a systematic accumulation of fundamental knowledge regarding materials and device development. Filling the informational void, this collection of information reviews state-of-the-art research and development trends reflecting nano and optical technologies, environmental regulation, and alternative energy sources. Like the first edition, which became a standard in the field, this volume provides a general introduction to ferroelectrics with theoretical background. It then addresses practical design and device manufacturing, including recently developed processes and applications. Updating old data with a forecast of future developments, the text analyzes improvements to original ferroelectric devices to aid the design process of new ones. The second edition includes new sections on: Pb-free piezoelectrics Size effect on ferroelectricity Electrocaloric devices Micro mass sensor Piezoelectric energy harvesting Light valves and scanners Multi-ferroic devices, including magneto-electric sensors Uchino provides a general introduction to the theoretical background of ferroelectric devices, practical materials, device designs, drive/control techniques, and typical applications. He presents frequently asked questions from students, lab demonstrations for practical understanding, and "check point" quizzes and model solutions to monitor understanding. After a thorough exploration of ferroelectric devices and their past, this book looks to the industry’s future, assessing market size and remaining reliability/lifetime issues. The author also unveils his strategy for developing "best-selling" ferroelectric devices.
