The book highlights established research and technology on current and emerging trends and biomedical applications of functionalized carbon nanotubes by providing academic researchers and scientists in industry, as well as high-tech start-ups, with knowledge of the modern practices that will revolutionize using functionalized carbon nanotubes. Nanotechnology suggests fascinating opportunities for a variety of applications in biomedical fields, including bioimaging and targeted delivery of biomacromolecules into cells. Numerous strategies have been recommended to functionalize carbon nanotubes with raised solubility for efficient use in biomedical applications. Functionalized carbon nanotubes have unique arrangements and extravagant mechanical, thermal, magnetic, optical, electrical, surface, and chemical properties, and the combination of these features gives them widespread biomedical applications. Functionalized carbon nanotubes are relatively flexible and interact with the cell membranes and penetrate different biological tissues owing to a “snaking” effect, therefore both the pharmacological and toxicological profiles of functionalized carbon nanotubes have gathered much attention in recent times.

The major themes on technology included Material Science & Engineering, Communication Science & Engineering, Computer Science & Engineering, Electrical & Electronic Engineering, Mechanical & Automation Engineering, Architecture Engineering, IOT Technology, and Innovation Design. Sentiment analysis of text data is an important task in natural language processing (NLP). Taking the product review system as an example, proper use of sentiment analysis can reveal the opinions of consumers, and thus adjustments can be made to products. However, most current sentiment analysis methods assume that there is a large amount of training data available for the classification model. The classification accuracy is not ideal when little data are available for analysis.Aiming at sentiment analysis of text data with few data samples, in this paper, we propose an embedded learning model, which combines convolutional neural network and bidirectional long short-term memory learning models to improve the relevance of data by dimensionality reduction and thus strengthen the classification accuracy of few-shot learning. In addition, we segment the training data and use them to train the proposed model in batches to avoid the overfitting problem that is often observed in few-shot learning models.

A key challenge in science and engineering is to provide a quantitative description of the systems under investigation, leveraging the noisy data collected. Such a description may be a complete mathematical model or a mechanism to return controllers corresponding to new, unseen inputs. Recent advances in the theories are described in detail, along with their applications in engineering. The book aims to develop model-free system analysis and control strategies, i.e., data-driven control from theoretical analysis and engineering applications based only on measured data. The study aims to develop system identification, and combination in advanced control theory, i.e., data-driven control strategy as system and controller are generated from measured data directly. The book reviews the development of system identification and its combination in advanced control theory, i.e., data-driven control strategy, as they all depend on measured data.

The mobile wheeled inverted pendulum (MWIP) is a typical underactuated robotic system, which is widely used in modern urban transportation vehicles aiming at solving the last mile problem. This book presents the achievements of the author's team in the research of a special underactuated system called mobile wheeled inverted pendulum (MWIP) developed over recent years. It focuses on a combination of theory and practice, and almost all algorithms are verified on the real MWIP system. Taking the dynamic modeling, control, and simulation as the mainline, this book first introduces the particularity, control challenges, and applications of the MWIP system. Then, Lagrange function is adopted to model the dynamics of two-dimensional and three-dimensional MWIP systems. Then, based on the special characteristics of the MWIP's dynamics, a new high-order disturbance observer is designed, and a control strategy is proposed by combining the high-order disturbance observer with a novel design of sliding mode manifold. Furthermore, several methods to overcome the chattering problem of the traditional sliding mode control are presented in detail. Finally, the future development of underactuated robot has been prospected.

Hydrogen electrical vehicles are an essential component of the “Green New Deal” and this book covers cutting-edge technologies designed for fuel-cell-powered cars. Fuel cells use hydrogen directly in most types of vehicles—from passenger cars to trains—without some of the disadvantages of batteries such as low energy density, high initial costs, and a slow charge. Therefore, the number of hydrogen filling stations required for fuel cells, about one-tenth of the number of fast-charging stations, can meet the same needs as batteries. Additionally, hydrogen charging is at least three times faster. Therefore, it is essential to emphasize that hydrogen-powered transportation is still the most reasonable way to reduce emissions. As part of our “Advances in Hydrogen Productıon and Storage” series, this volume covers the cutting-edge technologies used in fuel cell-powered cars. Additionally, it highlights the research efforts presented in the literature while adding a valuable component to the area. It also discusses basic as well as advanced engineering details for both scientists and engineers in academia and industry.

Metal-Air Batteries: Principles, Progress, and Perspectives covers the entire spectrum of metal-air batteries, their working principles, recent advancement, and future perspectives. Leading international researchers address materials design, electrochemistry, and architectural aspects. The fundamentals of metal-air materials for cathode and anode, their synthetic approaches, chemistries to modify their properties to provide high energy and power densities, along with long life and stable electrochemical characteristics are detailed. There is a need to develop high-performance and sustainable energy devices which could meet the future demand for energy on the consumer as well as industrial scale. Most of the current energy needs are fulflled by fossil fuels which are damaging our environment. Global warming and air pollution are some of the major issues caused by the use of excessive fossil fuels, and therefore researchers need to fnd some alternatives. Approaches such as the use of hybrid electric vehicles and electric vehicles are a few solutions to these problems. Adaptation of electric vehicles has some challenges such as low performance of the batteries, their life, cost, and range per charge. Metal-air batteries offer higher energy density compared to many other battery technologies. However, such technology has many challenges such as the use of advanced electrochemical materials, porous cathode, electrolytes, device architecture, etc.
