Photo-catalytic Control Technologies of Flue Gas Pollutants

By: Jiang Wu,Jianxing Ren,Weiguo Pan,Ping Lu,Yongfeng Qi

This book introduces the theory and applications of nanometer photocatalysis, and it briefly presents the concept of photocatalysts, photocatalytic reaction mechanisms and kinetics, and photocatalytic reactor design. In addition, the use of photocatalysis in the control of flue-gas pollutants is discussed in detail. The book also describes how a photocatalytic reactor is designed and implemented to evaluate the photocatalytic oxidation capacity of different photocatalysts on elemental mercury in a simulated flue gas. After that, the effect of photocatalysts on the SO2, NOx and Hg removal in the flue gas is studied. Photocatalytic cleaning technology can be applied not only in gas pollutant cleaning at power plants, but also in wastewater purification. Readers gain a comprehensive understanding of possible mercury emission control methods and the industrial applications of these technologies.

Coal Fired Flue Gas Mercury Emission Controls

By: Jiang Wu,Yan Cao,Weiguo Pan,Weiping Pan

Mercury (Hg) is one of the most toxic heavy metals, harmful to both the environment and human health. Hg is released into the atmosphere from natural and anthropogenic sources and its emission control has caused much concern. This book introduces readers to Hg pollution from natural and anthropogenic sources and systematically describes coal-fired flue gas mercury emission control in industry, especially from coal-fired power stations. Mercury emission control theory and experimental research are demonstrated, including how elemental mercury is oxidized into oxidized mercury and the effect of flue gas contents on the mercury speciation transformation process. Mercury emission control methods, such as existing APCDs (air pollution control devices) at power stations, sorbent injection, additives in coal combustion and photo-catalytic methods are introduced in detail. Lab-scale, pilot-scale and full-scale experimental studies of sorbent injection conducted by the authors are presented systematically, helping researchers and engineers to understand how this approach reduces the mercury emissions in flue gas and to apply the methods in mercury emission control at coal-fired power stations. Readers will arrive at a comprehensive understanding of various mercury emission control methods that are suitable for industrial applications. The book is intended for scientists, researchers, engineers and graduate students in the fields of energy science and technology, environmental science and technology and chemical engineering.

Piezotronics and Piezo-Phototronics

Applications to Third-Generation Semiconductors

By: Zhong Lin Wang,Yan Zhang,Weiguo Hu

Co-authored by the discoverer of the piezotronic effect, this book is a fundamental and comprehensive survey of piezotronics and piezo-phototronics. Piezotronics is a term broadly applied to devices fabricated using the piezopotential as a “gate” voltage to tune/control charge carrier transport at a contact or junction. The piezo-phototronic effect describes the use of the piezopotential to control the carrier generation, transport, separation and/or recombination for improving the performance of optoelectronic devices. The book first introduces the theory of the piezotronic effect and its applications in transistors, sensors, and catalysis. Subsequent chapters comprehensively cover the fundamentals of the piezo-phototronic effect and its impacts on photon sensors, solar cells, and LEDs. The updated and significantly expanded second edition covers the most recent advances and breakthroughs in this field over the last decade — gas, chemical, and biological nanosensors; quantum dots, wells, and wires; piezocatalysis; the piezo-photonic effect; and the pyro-phototronic effect. This seminal book serves as a basic text for scientists and students in the field of piezotronic devices and third-generation semiconductors.

Economic Reforms and Fertility Behaviour

A Study of a Northern Chinese Village

By: Weiguo Zhang

Based on an intensive fieldwork in a southern Hebei village in northern China (1992/3), the author takes an institutional approach and focuses on the way deliberate Chinese state policies driven by new economic and social agendas since the late 1970s have impacted on marriage, family relations and consequently on the way fertility trends have been adversely affected; the study is also very much concerned with the human dimension and the way in which such social and economic changes are perceived and applied in a rural community. The research presented in this study goes a long way to unravelling the puzzle concerning the reasons for a very rapid decline in Chinese fertility rates, contrasting sharply with a very different fertility transition within western cultures.
