Metal oxide nanomaterials exhibit interesting electrical and photochemical properties because of their size, stability, and high surface area that render them as great choices in fabricating alternative electrode materials for electrochemical energy storage and sensor applications. The hybridization of metal oxides with other materials lead to the improvement in electrical conductivity, stability, and electron transfer kinetics during the electrocatalytic reactions. These key factors result in greater sensitivity of the sensor materials towards the analyte molecules. This book reviews the electrochemical determination of a variety of toxic chemical contaminants using metal oxide-based nanocomposite materials. Ultrasensitive and selective detection of toxic chemical contaminants is important and demanding, especially for monitoring and controlling environmental pollution. In recent years, metal oxide-based nanocomposite materials have shown high potential in the electrochemical detection of heavy metals, inorganic anions, phenolic compounds, pesticides, and chemical warfare reagents. Metal Oxides in Nanocomposite-Based Electrochemical Sensors for Toxic Chemicals comprehensively reviews this topic. In addition to the instrumental simplicity, the electrochemical methods show the improved sensor performance through the synergetic effect of metal oxide and other electroactive nanomaterial present in the nanocomposite. Thus, detailed information on the electrochemical sensing of toxic chemical contaminants using metal oxide-based nanomaterials are discussed. The recent progress in developing electrochemical sensors using metal oxide-based nanocomposite materials and perspectives on future opportunities in sensor research and development are addressed in the book.

Deep Learning for Chest Radiographs enumerates different strategies implemented by the authors for designing an efficient convolution neural network-based computer-aided classification (CAC) system for binary classification of chest radiographs into "Normal" and "Pneumonia." Pneumonia is an infectious disease mostly caused by a bacteria or a virus. The prime targets of this infectious disease are children below the age of 5 and adults above the age of 65, mostly due to their poor immunity and lower rates of recovery. Globally, pneumonia has prevalent footprints and kills more children as compared to any other immunity-based disease, causing up to 15% of child deaths per year, especially in developing countries. Out of all the available imaging modalities, such as computed tomography, radiography or X-ray, magnetic resonance imaging, ultrasound, and so on, chest radiographs are most widely used for differential diagnosis between Normal and Pneumonia. In the CAC system designs implemented in this book, a total of 200 chest radiograph images consisting of 100 Normal images and 100 Pneumonia images have been used. These chest radiographs are augmented using geometric transformations, such as rotation, translation, and flipping, to increase the size of the dataset for efficient training of the Convolutional Neural Networks (CNNs). A total of 12 experiments were conducted for the binary classification of chest radiographs into Normal and Pneumonia. It also includes in-depth implementation strategies of exhaustive experimentation carried out using transfer learning-based approaches with decision fusion, deep feature extraction, feature selection, feature dimensionality reduction, and machine learning-based classifiers for implementation of end-to-end CNN-based CAC system designs, lightweight CNN-based CAC system designs, and hybrid CAC system designs for chest radiographs. This book is a valuable resource for academicians, researchers, clinicians, postgraduate and graduate students in medical imaging, CAC, computer-aided diagnosis, computer science and engineering, electrical and electronics engineering, biomedical engineering, bioinformatics, bioengineering, and professionals from the IT industry.

Magnetic skyrmions are particle-like objects described by localized solutions of non-linear partial differential equations. Up until a few decades ago, it was believed that magnetic skyrmions only existed in condensed matter as short-term excitations that would quickly collapse into linear singularities. The contrary was proven theoretically in 1989 and evidentially in 2009. It is now known that skyrmions can exist as long-living metastable configurations in low-symmetry condensed matter systems with broken mirror symmetry, increasing the potential applications possible. Magnetic Skyrmions and their Applications delves into the fundamental principles and most recent research and developments surrounding these unique magnetic particles. Despite achievements in the synthesis of systems stabilizing chiral magnetic skyrmions and the variety of experimental investigations and numerical calculations, there have not been many summaries of the fundamental physical principles governing magnetic skyrmions or integrating those concepts with methods of detection, characterization and potential applications. Magnetic Skyrmions and their Applications delivers a coherent, state-of-the-art discussion on the current knowledge and potential applications of magnetic skyrmions in magnetic materials and device applications. First the book reviews key concepts such as topology, magnetism and materials for magnetic skyrmions. Then, charactization methods, physical mechanisms, and emerging applications are discussed.

Fully Depleted Silicon-On-Insulator provides an in-depth presentation of the fundamental and pragmatic concepts of this increasingly important technology. There are two main technologies in the marketplace of advanced CMOS circuits: FinFETs and fully depleted silicon-on-insulators (FD-SOI). The latter is unchallenged in the field of low-power, high-frequency, and Internet-of-Things (IOT) circuits. The topic is very timely at research and development levels. Compared to existing books on SOI materials and devices, this book covers exhaustively the FD-SOI domain. Fully Depleted Silicon-On-Insulator is based on the expertise of one of the most eminent individuals in the community, Dr. Sorin Cristoloveanu, an IEEE Andrew Grove 2017 award recipient "For contributions to silicon-on-insulator technology and thin body devices." In the book, he shares key insights on the technological aspects, operation mechanisms, characterization techniques, and most promising emerging applications. Early praise for Fully Depleted Silicon-On-Insulator "It is an excellent written guide for everyone who would like to study SOI deeply, specially focusing on FD-SOI." --Dr. Katsu Izumi, Formerly at NTT Laboratories and then at Osaka Prefecture University, Japan "FDSOI technology is poised to catch an increasingly large portion of the semiconductor market. This book fits perfectly in this new paradigm [...] It covers many SOI topics which have never been described in a book before." --Professor Jean-Pierre Colinge, Formerly at TSMC and then at CEA-LETI, Grenoble, France "This book, written by one of the true experts and pioneers in the silicon-on-insulator field, is extremely timely because of the growing footprint of FD-SOI in modern silicon technology, especially in IoT applications. Written in a delightfully informal style yet comprehensive in its coverage, the book describes both the device physics underpinning FD-SOI technology and the cutting-edge, perhaps even futuristic devices enabled by it." --Professor Alexander Zaslavsky, Brown University, USA "A superbly written book on SOI technology by a master in the field." --Professor Yuan Taur, University of California, San Diego, USA "The author is a world-top researcher of SOI device/process technology. This book is his masterpiece and important for the FD-SOI archive. The reader will learn much from the book." --Professor Hiroshi Iwai, National Yang Ming Chiao Tung University, Taiwan From the author "It is during our global war against the terrifying coalition of corona and insidious computer viruses that this book has been put together. Continuous enlightenment from FD-SOI helped me cross this black and gray period. I shared a lot of myself in this book. The rule of the game was to keep the text light despite the heavy technical content. There are even tentative FD-SOI hieroglyphs on the front cover, composed of curves discussed in the book."
