Ion Exchange Membranes

Design, Preparation, and Applications

By: Tongwen Xu,Yaoming Wang

Ion Exchange Membranes A comprehensive introduction to the electro-membrane technologies of the future An ion exchange membrane is a polymer-based membrane which can be permeable by some ions in a solution while blocking others, making them ideal for processes such as water desalination, salt concentration control, clean production and—given their electrical conductivity—power generation and energy storage etc. Recent advances have given rise to new electro-membrane processes that promise drastically to expand the applications of this technology. Scientists in both research and industry will increasingly need to draw on these membranes in vital ways with strongly positive potential environmental impact. Ion Exchange Membranes summarizes recent research into these membranes and electro-membrane processes before moving to an overview of the historical background. It then attends in detail to cutting-edge fabrication technologies and the most recent areas of use. The result is a comprehensive introduction to the design, fabrication, and applications of these increasingly essential membranes. Ion Exchange Membranes readers will also find: In-depth treatment of industrial-scale applications Detailed discussion of topics including side-chain engineering, polyacylation, superacid-catalyst polymerization, and more Analysis of electro-membrane processes such as alkaline membrane water electrolysis, solar-driven water splitting, and many more Ion Exchange Membranes is ideal for membrane scientists, materials scientists, inorganic chemists, polymer chemists, and researchers and engineers in a variety of fields working with ion exchange membranes and electro-membrane processes.

Development and Evaluation of High Resolution Climate System Models

By: Rucong Yu,Tianjun Zhou,Tongwen Wu,Wei Xue,Guangqing Zhou

This book is based on the project “Development and Validation of High Resolution Climate System Models” with the support of the National Key Basic Research Project under grant No. 2010CB951900. It demonstrates the major advances in the development of new, dynamical Atmospheric General Circulation Model (AGCM) and Ocean General Circulation Model (OGCM) cores that are suitable for high resolution modeling, the improvement of model physics, and the design of a flexible, multi-model ensemble coupling framework. It is a useful reference for graduate students, researchers and professionals working in the related areas of climate modeling and climate change. Prof. Rucong Yu works at the China Meteorological Administration; Prof. Tianjun Zhou works at LASG, the Institute of Atmospheric Physics, Chinese Academy of Sciences; Tongwen Wu works at Beijing Climate Center, China Meteorological Administration; Associate Prof. Wei Xue works at the Department of Computer Science and Technology, Tsinghua University; Prof. Guangqing Zhou works at the Institute of Atmospheric Physics (IAP), Chinese Academy of Sciences.

Event-Based State Estimation

A Stochastic Perspective

By: Dawei Shi,Ling Shi,Tongwen Chen

This book explores event-based estimation problems. It shows how several stochastic approaches are developed to maintain estimation performance when sensors perform their updates at slower rates only when needed. The self-contained presentation makes this book suitable for readers with no more than a basic knowledge of probability analysis, matrix algebra and linear systems. The introduction and literature review provide information, while the main content deals with estimation problems from four distinct angles in a stochastic setting, using numerous illustrative examples and comparisons. The text elucidates both theoretical developments and their applications, and is rounded out by a review of open problems. This book is a valuable resource for researchers and students who wish to expand their knowledge and work in the area of event-triggered systems. At the same time, engineers and practitioners in industrial process control will benefit from the event-triggering technique that reduces communication costs and improves energy efficiency in wireless automation applications.
