Microplastics in Urban Water Management Enables readers to understand the true occurrence and fate of microplastics in drinking water, wastewater and sludge, and receiving water Microplastics in Urban Water Management focuses on the occurrence, fate, effect, and removal of microplastics in the urban water management systems, summarizing relevant methods for enhancing microplastics removal and degradation, providing comprehensive data from source to sink (including occurrence and fate of microplastics in urban water management), and covering practical applications, which are expected to provide some theoretical guidance for controlling or mitigating microplastics pollution and its environmental risks. The work also includes detailed multidisciplinary information on the way in which microplastics behave in urban water management, plus recent advances of nanoplastics, i.e., nano-sized microplastics, in the aquatic environment. In Microplastics in Urban Water Management, readers can expect to find detailed information on sample topics such as: Techniques for microplastics detection, including sample collection, purification, identification, and quantitation, plus the definition, emergence, occurrence, and removal of microplastics Elements of microplastics in wastewater treatment plants; for instance, the ecotoxicological effect on the biological treatment of wastewater and sludge Why the discharge of microplastics from wastewater treatment plants is the important source of microplastics in the receiving waters Potential environmental risks of microplastic contamination in receiving water systems and evidence that microplastics can absorb, collect and transport environmental contaminants as vectors For practicing toxicologists, biologists, environmental and chemical engineers, and ecology professionals, as well as researchers and graduate students in these disciplines, Microplastics in Urban Water Management is an essential all-in-one guide to understanding the current state of microplastics in our world and potential solutions for the future.

Calculations and Simulations of Low-Dimensional Materials A comprehensive guide to methods for calculating and simulating the properties of low-dimensional materials Two-dimensional materials are those, such as graphene and 2D oxides, whose thickness is so small as to approach the atomic scale. Potential applications for these materials exist in an enormous range of scientific and industrial fields. A previous era of low-dimensional materials focused on direct experimentation to demonstrate the properties, reactions, and potential applications of these materials; however, in recent years, calculation and simulation have been shown to have considerable predictive power, reducing the period between design and deployment of these potentially critical materials. Calculations and Simulations of Low-Dimensional Materials offers the first comprehensive survey of this exciting new approach to low-dimensional materials. It guides readers through the foundational physics and through a range of calculation and simulation methods, each with different predictive capacities. Mastery of these methods will enable readers to narrowly tailor the properties of particular materials towards real-world applications, providing confidence in the underlying mechanics and in the range of possible outcomes. Calculations and Simulations of Low-Dimensional Materials readers will also find: Broad coverage of material properties, including electronic, spin, magnetic, photonic, optical, electrochemical and transport properties Discussion of potential applications in areas such as electronics, spintronics, and valleytronics Examination of further potential applications regarding quantum Hall phase, photonics, optoelectronics, multiferroic, and photocatalysis Calculations and Simulations of Low-Dimensional Materials is a useful reference for materials scientists, electrochemists, inorganic chemists, physical chemists, photochemists, and the libraries that support these professions.

Linear Systems: Non-Fragile Control and Filtering presents the latest research results and a systematic approach to designing non-fragile controllers and filters for linear systems. The authors combine the algebraic Riccati technique, the linear matrix inequality (LMI) technique, and the sensitivity analysis method to establish a set of new non-fragile (insensitive) control methods. This proposed method can optimize the closed-loop system performance and make the designed controllers or filters tolerant of coefficient variations in controller or filter gain matrices.A Systematic Approach to Designing Non-Fragile Controllers and Filters for Linear SystemsThe text begins with developments and main research methods in non-fragile control. It then systematically presents novel methods for non-fragile control and filtering of linear systems with respect to additive/multiplicative controller/filter gain uncertainties. The book introduces the algebraic Riccati equation technique to solve additive/multiplicative norm-bounded controller/filter gain uncertainty, and proposes a structured vertex separator to deal with the numerical problem resulting from interval-bounded coefficient variations. It also explains how to design insensitive controllers and filters in the framework of coefficient sensitivity theory. Throughout, the book includes numerical examples to demonstrate the effectiveness of the proposed design methods.More Effective Design Methods for Non-Fragile Controllers and FiltersThe design and analysis tools described will help readers to better understand and analyze parameter uncertainties and to design more effective non-fragile controllers and filters. Providing a coherent approach, this book is a valuable reference for researchers, graduate students, and anyone who wants to explore the area of non-fragile control and filtering.
