This book highlights the present scenario of energy demand and power generation technologies in tropical countries. The tropics are well known to receive direct sunlight. Furthermore, different than four-season countries, tropical countries have a continuous summer-like season, and therefore, they are rich in clean energy sources, like solar and biomass. Home to 40% of the world's population, the demand for energy in these countries keeps increasing. With the present serious global concern on the environment, the choice of power generation is no doubt the cleanest possible resources. This book delves into the opportunity that various tropical countries have in pursuing environmentally friendly power generation systems.

Time is a great mystery. A changeable element, which expands or vanishes, but that appears concrete as it is marked by the passing of seconds, minutes, hours, days, and years. The path toward the capture of minutes and seconds coincided with the phases of scientific evolution that allowed man to manufacture watches that are increasingly reliable, but that are also in tune with changes in customs, social needs, and aesthetic canons. This book covers the art of watch manufactory as well as 60 great models, covering both their technical evolution and style trends. In each chapter in-depth studies will guide the reader to the history of the most important manufacturers, the personalities linked to the models treated, technical innovations, styles of the period, or records achieved by the wristwatches: from the watch that helped Charles Lindbergh during the first transatlantic solo flight, to the one worn by Sir Edmund Hillary on the top of Mount Everest, the most iconic models will be discussed in detail.
This book covers the physical properties of nanosized ferroics, also called nanoferroics. Nanoferroics are an important class of ceramic materials that substitute conventional ceramic ferroics in modern electronic devices. They include ferroelectric, ferroelastic, magnetic and multiferroic nanostructured materials. The phase transitions and properties of these nanostructured ferroics are strongly affected by the geometric confinement originating from surfaces and interfaces. As a consequence, these materials exhibit a behavior different from the corresponding bulk crystalline, ceramic and powder ferroics. This monograph offers comprehensive coverage of size- and shape-dependent effects at the nanoscale; the specific properties that these materials have been shown to exhibit; the theoretical approaches that have been successful in describing the size-dependent effects observed experimentally; and the technological aspects of many chemical and physico-chemical nanofabrication methods relevant to making nanoferroic materials and composites. The book will be of interest to an audience of condensed matter physicists, material scientists and engineers, working on ferroic nanostructured materials, their fundamentals, fabrication and device applications.

Different future and present applications, such as charging of vehicles, smart medical health care, self-driven e-vehicles, self-sustainable home automation system, and wireless drones, have also been discussed in detail.
This book demonstrates how to use the Synopsys Sentaurus TCAD 2014 version for the design and simulation of 3D CMOS (complementary metal-oxide-semiconductor) semiconductor nanoelectronic devices, while also providing selected source codes (Technology Computer-Aided Design, TCAD). Instead of the built-in examples of Sentaurus TCAD 2014, the practical cases presented here, based on years of teaching and research experience, are used to interpret and analyze simulation results of the physical and electrical properties of designed 3D CMOSFET (metal-oxide-semiconductor field-effect transistor) nanoelectronic devices. The book also addresses in detail the fundamental theory of advanced semiconductor device design for the further simulation and analysis of electric and physical properties of semiconductor devices. The design and simulation technologies for nano-semiconductor devices explored here are more practical in nature and representative of the semiconductor industry, and as such can promote the development of pioneering semiconductor devices, semiconductor device physics, and more practically-oriented approaches to teaching and learning semiconductor engineering. The book can be used for graduate and senior undergraduate students alike, while also offering a reference guide for engineers and experts in the semiconductor industry. Readers are expected to have some preliminary knowledge of the field.

This thesis presents the SiGe source and drain (S/D) technology in the context of advanced CMOS, and addresses both device processing and epitaxy modelling. As the CMOS technology roadmap calls for continuously downscaling traditional transistor structures, controlling the parasitic effects of transistors, e.g. short channel effect, parasitic resistances and capacitances is becoming increasingly difficult. The emergence of these problems sparked a technological revolution, where a transition from planar to three-dimensional (3D) transistor design occurred in the 22nm technology node. The selective epitaxial growth (SEG) method has been used to deposit SiGe as stressor material in S/D regions to induce uniaxial strain in the channel region. The thesis investigates issues of process integration in IC production and concentrates on the key parameters of high-quality SiGe selective epitaxial growth, with a special focus on its pattern dependency behavior and on key integration issues in both 2D and 3D transistor structures, the goal being to improve future applications of SiGe SEG in advanced CMOS.

This book is a comprehensive introduction to nanoscale materials for sensor applications, with a focus on connecting the fundamental laws of physics and the chemistry of materials with device design. Nanoscale sensors can be used for a wide variety of applications, including the detection of gases, optical signals, and mechanical strain, and can meet the need to detect and quantify the presence of gaseous pollutants or other dangerous substances in the environment. Gas sensors have found various applications in our daily lives and in industry. Semiconductive oxides, including SnO2, ZnO, Fe2O3, and In2O3, are promising candidates for gas sensor applications. Carbon nanomaterials are becoming increasingly available as off-the-shelf components, and this makes nanotechnology more exciting and approachable than ever before. Nano-wire based field- effect transistor biosensors have also received much attention in recent years as a way to achieve ultra-sensitive and label-free sensing of molecules of biological interest. A diverse array of semiconductor-based nanostructures has been synthesized for use as a photoelectrochemical sensor or biosensor in the detection of low concentrations of analytes. A novel acoustic sensor for structural health monitoring (SHM) that utilizes lead zirconate titanate (PZT) nano- active fiber composites (NAFCs) is described as well.
1 1. 1 Introduction The (signal processing and storage) capacity ofthe human brain enables us to become powerful autonomous beings, but only if our brains operate in conjunction with (at least some of) our senses and muscles. Using these organs, we can interact with our environment, learn to adapt, and improve important aspects of our life. Similarly, the signal processing capabilities of modern electronics (computers) could be combined with electronic sensors and actuators to enable interaction with, and adaptation to, the (non-electrical) environment. This willlead to smarter and more powerful automated tools and machines. To facilitate and stimulate such a development, easy-to-use low-cost sensors are needed. The combination of electronic interface functions and a sensor in an integrated smart sensor, that provides a standard, digital, and bus-compatible output, would simplify the connection of sensors to standard electronic signal processors (microcontrollers, computers, etc. ). Currently, the calibration procedure, required for standardization of the sensor output signal level, contributes largely to the production costs of accurate sensors. To enable automation of the calibration procedure, and hence reduce the sensor fabrication costs, a digital calibrationjunction should be included in the smart sensor. INTEGRATED SMART SENSORS: Design and Calibration Introduction 1. 2 Sensors and actuators In industry many processes are electronically controlled. As depicted in Fig.
This book covers a wide range of topics relating to carbon nanomaterials, from synthesis and functionalization to applications in advanced biomedical devices and systems. As they possess unique and attractive chemical, physical, optical, and even magnetic properties for various applications, considerable effort has been made to employ carbon nanomaterials (e.g., fullerenes, carbon nanotubes, graphene, nanodiamond) as new materials for the development of novel biomedical tools, such as diagnostic sensors, imaging agents, and drug/gene delivery systems for both diagnostics and clinical treatment. Tremendous progress has been made and the scattered literature continues to grow rapidly. With chapters by world-renowned experts providing an overview of the state of the science as well as an understanding of the challenges that lie ahead, Carbon Nanomaterials for Biomedical Applications is essential reading not only for experienced scientists and engineers in biomedical and nanomaterials areas, but also for graduate students and advanced undergraduates in materials science and engineering, chemistry, and biology.
Now back in print, this life of George Eastman is the first biography since 1930 of the man who transformed the world of photography. In this revealing and informative work, Brayer shows us how such key innovations as roll film and the light, hand-held camera helped the Eastman Kodak Company dominate the world market. More importantly, Brayer draws a vivid portrait of the man behind the money. Eastman worked hard at staying out of the limelight and even insisted that his donations be kept anonymous, prompting the Boston Globe to call him "America's most modest and least-known millionaire." Despite his retirement in 1925, Eastman showed little sign of slowing down. Making money had been interesting, but putting money to work became more so. In the 1920s he designed a special camera for use in orthodontia and established elaborate dental clinics for needy children around the world. He oversaw the building of the Eastman theatre and the Eastman School of Music. His contributions built a new campus for the Massachusetts Institute of Technology and a new medical school for the University of Rochester. Finally, he became the largest contributor to the education of African Americans during the 1920s and the Tuskegee Institute's most important benefactor. Elizabeth Brayer lives in Rochester, NY. For the past 18 years she has served on both the George Eastman Legacy and the Landscape committees at the George Eastman House, International Museum of Photography and Film. She writes about the history of central and Western New York State. George Eastman: A Biography was nominated for a Pulitzer Prize in 1996.
A variety of nanomaterials have excellent optoelectronic and electronic properties for novel device applications. At the same time, and with advances in silicon integrated circuit (IC) techniques, compatible Si-based nanomaterials hold promise of applying the advantages of nanomaterials to the conventional IC industry. This book focuses not only on silicon nanomaterials, but also summarizes up-to-date developments in the integration of non-silicon nanomaterials on silicon. The book showcases the work of leading researchers from around the world who address such key questions as: Which silicon nanomaterials can give the desired optical, electrical, and structural properties, and how are they prepared? What nanomaterials can be integrated on to a silicon substrate and how is this accomplished? What Si-based nanomaterials may bring a breakthrough in this field? These questions address the practical issues associated with the development of nanomaterial-based devices in applications areas such as solar cells, luminous devices for optical communication (detectors, lasers), and high mobility transistors. Investigation of silicon-based nanostructures is of great importance to make full use of nanomaterials for device applications. Readers will receive a comprehensive view of Si-based nanomaterials, which will hopefully stimulate interest in developing novel nanostructures or techniques to satisfy the requirements of high performance device applications. The goal is to make nanomaterials the main constituents of the high performance devices of the future.
