This book covers the topic of vibration energy harvesting using piezoelectric materials. Piezoelectric materials are analyzed in the context of their electromechanical coupling, heterogeneity, microgeometry and interrelations between electromechanical properties. Piezoelectric ceramics and composites based on ferroelectrics are advanced materials that are suitable for harvesting mechanical energy from vibrations using inertial energy harvesting which relies on the resistance of a mass to acceleration and kinematic energy harvesting which couples the energy harvester to the relative movement of different parts of a source. In addition to piezoelectric materials, research efforts to develop optimization methods for complex piezoelectric energy harvesters are also reviewed. The book is important for specialists in the field of modern advanced materials and will stimulate new effective piezotechnical applications.
The purpose of this book is to introduce the phosphorus (P) removal structure as a new BMP for reducing dissolved P loading to surface waters from non-point source pollution, provide guidance on designing site-specific P removal structures, and provide instruction on use of the design software, “Phrog” (Phosphorus Removal Online Guidance). The book initially provides a review of the nature and sources of non-point source P pollution, examines short and long term solutions to the problem, and provides detailed theory on design and operation of the P removal structure. As with many areas of study, one of the best methods of communicating concepts is through illustrations and examples. This book is no exception; several years of experience in studying P sorption and constructing P removal structures at multiple scales and settings is utilized for providing real examples and applications. With an understanding of the P removal structure established, the reader is instructed on how to obtain all of the necessary inputs for properly designing a site-specific P removal structure for meeting a desired lifetime and performance, or predict the performance and lifetime of a previously constructed P removal structure. For the readers who already possess the Phrog design software or are interested in obtaining it, one chapter is dedicated to detailed use of the software as demonstrated with various examples of structure design and also prediction.
This monograph provides researchers, engineers, postgraduates and lecturers working in the field of ferroelectric or piezoelectric and related materials with features of the structure-property relationships in modern piezo-active composites. These are piezoelectric composites which are active dielectric materials, which can be poled ferroelectric ceramics or domain-engineered single crystals poled along specific crystallographic directions. Current knowledge of the effective physical properties of these materials is lacking especially due to gaps of information in physical, chemical, microgeometric and technological factors. For composite and transducer design purposes, the expected properties of these piezo-active materials have been theorized through models by the authors and proven in experiments. Various well-known journals have published this research, among many others: Smart Materials and Structures; Journal of Physics D: Applied Physics; IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control; Acta Materialia.The book summarises and generalises a series of authors' works on the problem of the effective properties and related parameters of modern two- and three-component piezo-active composites wherein the microgeometric factor plays the dominating role. Specific examples of the performance of composites based on domain-engineered single crystals are also discussed. New trends are described in the research of modern piezo-active composites with the aim of filling the gaps in piezoelectric materials science. The primary goal of the book is to show advantages of different methods being applied to manufacture and study the functional composites that are suitable for piezoelectric energy harvesting, hydroacoustic, sensor, actuator, and other transducer applications.

It is clear that lysosomal enzymes often play a role in the destruction of the cytoplasm, but very few authorities feel that they initiate the process (Chapters 1, 2, 3, 5 -8, 12, 13). The cells show many forms of damage, and sometimes even complete destruction, before Iysosomes become a dominant part of the environ ment. What initiates the process is still unclear, although in several instances it appears that the death of a cell may arise from anyone of several pathways (Chapters, 10, II). It is rather interesting that evolution has chosen to achieve the same goal by different means. Apparently no one point is exceptionally or pre ferentially vulnerable, though a common pathway, such as permeability of the plasma membrane to calcium (Chapter 7), might currently be too subtle for routine identification. Factors which affect membrane stability and which induce mem brane bending can lead to blebing, cell fragmentation and death. Thus, more work on the changing chemistry of the plasma membrane in relation to environmental fluctuations would be welcomed. Space requirements and the major orientation of the book forced the exclusion of several very interesting topics: an evolutionary treatment of the advantages of cell death as a means of eliminating vestigial organs or embryonic scaffolding; or consider ation of the merits of body sculpting by cell death rather than cell growth.
This book is devoted to the systematic description of the role of microgeometry of modern piezo-active composites in the formation of their piezoelectric sensitivity. In five chapters, the authors analyse kinds of piezoelectric sensitivity for piezo-active composites with specific connectivity patterns and links between the microgeometric feature and piezoelectric response. The role of components and microgeometric factors is discussed in the context of the piezoelectric properties and their anisotropy in the composites. Interrelations between different types of the piezoelectric coefficients are highlighted. This book fills a gap in piezoelectric materials science and provides readers with data on the piezoelectric performance of novel composite materials that are suitable for sensor, transducer, hydroacoustic, energy-harvesting, and other applications.
Next to air, water is the most essential of human requirements. The hydrosphere-the waters of the Earth, its oceans, rivers and lakes-is vital, constituting a feature unique in the solar system and one responsible for physical and climatic phenomena characteristic of the planet. Water moves through the hydrologic cycle and runs the heat engine of the Earth, approximately 97% of it occurring in the oceans. These contain vast natural resources including abundant plant and animal life and they assist in cleansing the atmosphere by becoming the final repository of air and land pollutants of which many are man-made. Unfortunately their ability to do this is diminishing because of rising pollution by toxicants such as DDT, nuclear by-products such as strontium-90 and oil spills. The oceans contain huge quantities of various substances mostly originating from the atmosphere, biological activity, river transport after rock weathering, groundwater, spreading zones along mid-oceanic ridges and crustal out-gassing. After hydrogen and oxygen, the commonest elements in them are Cl, Na, Mg, S, K, Ca, Br, C and B. The atmosphere and the oceans together cooperate in an energy cycle important in controlling and equalising the Earth's surface temperature.
This is an open access book. This book presents new theory and methods on compiling lithofacies paleogeographic maps as a key tool for guiding geological survey on shale gas. The fundamental goal of the shale gas geological survey is to find the ‘dessert’ area. It is therefore suggested that the lithofacies paleogeographic study and the technique of mapping should be a solid scientific basis for shale gas exploration. It takes Ordovician Wufeng-Silurian Longmaxi Formation in Sichuan Basin and its adjacent area as an example to illustrate how to find the ‘dessert’ area of shale gas in geological survey phase by compiling lithofacies paleogeographic map. It’s a valuable reference for both scientific research and teaching courses in the fields of sedimentary lithofacies, paleogeography, stratigraphy, and oil and gas.
Accelerating progress in the application of radioactive and stable isotope analysis to a varied range of geologicla and geochemical problems in geology has required a complete revision of Isotopes in the Earth Sciences, published in 1988. This new book comprises four parts: the first introduces isotopic chemistry and examines mass spectroscopic methods; the second eeals with radiometric dating methods. Part Three examines the importance of isotopes in climato-environmental studies, and increasingly significant area of research. The last part looks at extra-terrestrial matter, geothermometry and the isotopic geochemistry of the Earth's lithosphere. Post-graduate and post-doctoral researchers in geochemistry, as well as final year undergraduates in the earth and environmental sciences, will find Radioactive and Stable Isotope Geology an invaluable, uo-to-date and thorough treatment of the theory and practice of isotopie geology.
In one of his commencement talks as President of Princeton University, William G. Bowen called upon the assembled graduates to find ways, in their lives, to blend "the powers of the mind and the promptings of the heart." This collection of his presidential writings--drawn from annual reports, opening exercises addresses, commencement remarks, and other speeches and essays--reflects a blend of analysis and advocacy that speaks both to public policy issues affecting all of American higher education and to the deeper meanings and values of Princeton. The writings selected for inclusion here represent roughly half of the total archive annotated in Appendix B. They range from brief extracts to complete documents, and they are organized under such topics as the university in society; purposes of education/liberal education; graduate education, scholarship, and research; faculty; diversity, opportunity, and financial aid; the economics of the private research university; and a final chapter titled simply "Reflections." Throughout his fifteen-year tenure, President Bowen remained a teacher in the introductory economics course at Princeton, and his principal identification was always as a member of the faculty. His writings, as he saw them, were an extension of his teaching: an opportunity to communicate important ideas in ways that would sharpen his own understanding at the same time that they provoked others to think hard about the questions being raised. As such, his writings were a source of insight and illumination for many "students," of various descriptions, who listened, and read, and learned from what he had to say. Originally published in 1988. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

The scales involved in modern semiconductor manufacturing and microelectronics continue to plunge downward. Effective and accurate characterization of materials with thicknesses below a few nanometers can be achieved using x-rays. While many books are available on the theory behind x-ray metrology (XRM), X-Ray Metrology in Semiconductor Manufacturing is the first book to focus on the practical aspects of the technology and its application in device fabrication and solving new materials problems. Following a general overview of the field, the first section of the book is organized by application and outlines the techniques that are best suited to each. The next section delves into the techniques and theory behind the applications, such as specular x-ray reflectivity, diffraction imaging, and defect mapping. Finally, the third section provides technological details of each technique, answering questions commonly encountered in practice. The authors supply real examples from the semiconductor and magnetic recording industries as well as more than 150 clearly drawn figures to illustrate the discussion. They also summarize the principles and key information about each method with inset boxes found throughout the text. Written by world leaders in the field, X-Ray Metrology in Semiconductor Manufacturing provides real solutions with a focus on accuracy, repeatability, and throughput.
