Advanced Material Interfaces is a state-of-the-art look at innovative methodologies and strategies adopted for interfaces and their applications. The 13 chapters are written by eminent researchers not only elaborate complex interfaces fashioned of solids, liquids, and gases, but also ensures cross-disciplinary mixture and blends of physics, chemistry, materials science, engineering and life sciences. Advanced interfaces operate fundamental roles in essentially all integrated devices. It is therefore of the utmost urgency to focus on how newly-discovered fundamental constituents and interfacial progressions can be materialized and used for precise purposes. Interfaces are associated in wide multiplicity of application spectrum from chemical catalysis to drug functions and the advancement is funnelled by fine-tuning of our fundamental understanding of the interface effects.

This book, written by an international group of experts from China, Europe and the USA, presents a broad and comprehensive analysis of the chemical and meteorological processes responsible for the formation of air pollutants in eastern Asia, and in particular for the development of severe pollution episodes observed primarily during winter in the northeastern part of China. With the rapid population growth, economic development and urbanization occurring in Asia, air pollution has become a major environmental problem in this part of the world. The book is organized around six distinct parts. The first part of the volume offers a general perspective on issues related to air pollution including persistent haze events in eastern and southern Asia. The second part presents an overview of air pollution sources (i.e., anthropogenic and biomass burning sources). The third part analyzes in-situ observations of chemical species in China, while the fourth part focuses on space observations of gas-phase and aerosol species. The modeling aspects are treated in the fifth part of the volume, which includes a presentation of several air quality forecast systems and an assessment of the role of urbanization on air pollution levels. Finally, the effects of air pollution on health and crop productivity in China are discussed in the last part of the book. The book also presents an integrated view of past and present situations in Asia and provides the scientific basis from which mitigation policies can be established and air quality can be improved. Audience: This book is written for scientists, educators, students, environmental managers, policy-makers and leaders in public administration and private corporations who wish to use science-based information to mitigate air pollution. The book should help decision-makers to design effective policies for air quality improvement and to successfully manage short-term air pollution episodes that substantially affect people’s quality of life and strongly impact the economy.

Introduces chaos theory, its analytical methods and themeans to apply chaos to the switching power supplydesign DC-DC converters are typical switching systems which have plentyof nonlinear behaviors, such as bifurcation and chaos. Thenonlinear behaviors of DC-DC converters have been studied heavilyover the past 20 years, yet researchers are still unsure of thepractical application of bifurcations and chaos in switchingconverters. The electromagnetic interference (EMI), which resultedfrom the high rates of changes of voltage and current, has become amajor design criterion in DC-DC converters due to wide applicationsof various electronic devices in industry and daily life, and thequestion of how to reduce the annoying, harmful EMI has attractedmuch research interest. This book focuses on the analysis andapplication of chaos to reduce harmful EMI of DC-DC converters. After a review of the fundamentals of chaos behaviors of DC-DCconverters, the authors present some recent findings such asSymbolic Entropy, Complexity and Chaos Point Process, to analyzethe characters of chaotic DC-DC converters. Using these methods,the statistic characters of chaotic DC-DC converters are extractedand the foundations for the following researches of chaotic EMIsuppression are reinforced. The focus then transfers to estimatingthe power spectral density of chaotic PWM converters behind anintroduction of basic principles of spectrum analysis and chaoticPWM technique. Invariant Density, and Prony and Wavelet analysismethods are suggested for estimating the power spectral density ofchaotic PWM converters. Finally, some design-orientedapplications provide a good example of applying chaos theory inengineering practice, and illustrate the effectiveness onsuppressing EMI of the proposed chaotic PWM. Introduces chaos theory, its analytical methods and the meansto apply chaos to the switching power supply design Approaches the subject in a systematic manner from analyzingmethod, chaotic phenomenon and EMI characteristics, analyticalmethods for chaos, and applying chaos to reduce EMI(electromagnetic interference) Highlights advanced research work in the fields of statisticcharacters of nonlinear behaviors and chaotic PWM technology tosuppress EMI of switching converters Bridges the gap between numerical theory and real-worldapplications, enabling power electronics designers to both analyzethe effects of chaos and leverage these effects to reduce EMI
