Functionalized Processing for Thermoplastic Polymers

By: Guoqiang Zheng

Thermoplastic polymers account for more than 80 wt.% of all polymer materials. They will become soft and finally flowable upon heating, and inversely solid when they are cooled down. Therefore, various kinds of products based on thermoplastic polymers, widely used in daily life, automobile and electronic industry, etc., can be facilely fabricated by conventional melt processing methods (e.g., extrusion, injection molding, hot-pressing and so on). In a word, melt processing methods are a crucial bridge between thermoplastic polymers and their wide applications.

A Decade of Upheaval

The Cultural Revolution in Rural China

By: Dong Guoqiang,Andrew G. Walder

A revealing exploration of political disruption and violence in a rural Chinese county during the Cultural Revolution A Decade of Upheaval chronicles the surprising and dramatic political conflicts of a rural Chinese county over the course of the Cultural Revolution. Drawing on an unprecedented range of sources—including work diaries, interviews, internal party documents, and military directives—Dong Guoqiang and Andrew Walder uncover a previously unimagined level of strife in the countryside that began with the Red Guard Movement in 1966 and continued unabated until the death of Mao Zedong in 1976. Showing how the upheavals of the Cultural Revolution were not limited to urban areas, but reached far into isolated rural regions, Dong and Walder reveal that the intervention of military forces in 1967 encouraged factional divisions in Feng County because different branches of China’s armed forces took various sides in local disputes. The authors also lay bare how the fortunes of local political groups were closely tethered to unpredictable shifts in the decisions of government authorities in Beijing. Eventually, a backlash against suppression and victimization grew in the early 1970s and resulted in active protests, which presaged the settling of scores against radical Maoism. A meticulous look at how one overlooked region experienced the Cultural Revolution, A Decade of Upheaval illuminates the all-encompassing nature of one of the most unstable periods in modern Chinese history.

The Electrical Contact of the Pantograph-Catenary System

Theory and Application

By: Guangning Wu,Guoqiang Gao,Wenfu Wei,Zefeng Yang

This book covers the basic scientific theory and related application technologies of the pantograph–catenary system, including research findings on pantograph/catenary contact resistance, pantograph interface thermal effect, laws and characteristics of current-carrying friction and wear, the main research methods for pantograph arcs, the effects of arcs on pantograph systems and onboard equipment, and the materials used for pantographs and contact wires. Given its scope, it offers a valuable resource for students, scholars, and development engineers alike. The relationship between pantograph and catenary is one of the three core aspects of the safe operation of high-speed electrified railways. The pantograph system provides electric power for the high-speed train through the sliding electric contact. As the train’s operating speed increases, the pantograph system enters a state of prolonged sliding/vibration, resulting in frequent arcs, electrode erosion, and increased wear.

Self-Healing Composites

Shape Memory Polymer Based Structures

By: Guoqiang Li

In this book, the self-healing of composite structures with shape memory polymer as either matrix or embedded suture is systematically discussed. Self-healing has been well known in biological systems for many years: a typical example is the self-healing of human skin. Whilst a minor wound can be self-closed by blood clotting, a deep and wide cut needs external help by suturing. Inspired by this observation, this book proposes a two-step close-then-heal (CTH) scheme for healing wide-opened cracks in composite structures–by constrained shape recovery first, followed by molecular healing. It is demonstrated that the CTH scheme can heal wide-opened structural cracks repeatedly, efficiently, timely, and molecularly. It is believed that self-healing represents the next-generation technology and will become an engineering reality in the near future. The book consists of both fundamental background and practical skills for implementing the CTH scheme, with additional focus on understanding strain memory versus stress memory and healing efficiency evaluation under various fracture modes. Potential applications to civil engineering structures, including sealant for bridge decks and concrete pavements, and rutting resistant asphalt pavements, are also explored. This book will help readers to understand this emerging field, and to establish a framework for new innovation in this direction. Key features: explores potential applications of shape memory polymers in civil engineering structures, which is believed to be unique within the literature balanced testing and mathematical modeling, useful for both academic researchers and practitioners the self-healing scheme is based on physical change of polymers and is written in an easy to understand style for engineering professionals without a strong background in chemistry

Near-infrared Speckle Contrast Diffuse Correlation Tomography for Noncontact Imaging of Tissue Blood Flow Distribution

By: Daniel Irwin,Siavash Mazdeyasna,Chong Huang,Mehrana Mohtasebi,Xuhui Lui,Lei Chen,Guoqiang Yu

Imaging of tissue blood flow (BF) distributions provides vital information for the diagnosis and therapeutic monitoring of various vascular diseases. The innovative near-infrared speckle contrast diffuse correlation tomography (scDCT) technique produces full 3D BF distributions. Many advanced features are provided over competing technologies including high sampling density, fast data acquisition, noninvasiveness, noncontact, affordability, portability, and translatability across varied subject sizes. The basic principle, instrumentation, and data analysis algorithms are presented in detail. The extensive applications are summarized such as imaging of cerebral BF (CBF) in mice, rat, and piglet animals with skull penetration into deep brain. Clinical human testing results are described by recovery of BF distributions on preterm infants (CBF) through incubator wall, and on sensitive burn tissues and mastectomy skin flaps without direct device-tissue interactions. Supporting activities outlined include integrated capability for acquiring surface curvature information, rapid 2D blood flow mapping, and optimizations via tissue-like phantoms and computer simulations. These applications and activities both highlight and guide the reader as to the expected abilities and limitations of scDCT for adapting into their own preclinical/clinical research, use in constrained environments (i.e., neonatal intensive care unit bedside), and use on vulnerable subjects and measurement sites.

China’s Reform: History, Logic, and Future

By: Guoqiang Tian,Xudong Chen

This book is about where to go and what to do in China’s reform. Its comprehensive overview and economic analysis of China’s reform offers a coverage not found in other English language text. It provides an overview of China’s development and reform practice, an economic analysis of China’s market-oriented reform and a brief introduction to the theoretical origin, practices, and defects of the planned economy. In so doing, this book demonstrates that the key to the success of China’s reform lies in drawing reasonable governance boundaries between government and the market and between government and society. It further discusses the basic elements required for modernizing China’s state governance system and conducts an analysis of China’s reform and development in 13 key fields. The analysis is based on three dimensions—theoretical logic, practical knowledge, and a historical perspective. This book proposes three elements of comprehensive state governance—inclusive economic institutions; the state capacity to plan and implement policies and laws; and an inclusive and transparent civil society with democracy, the rule of law, fairness, and justice. Its analysis also features the novel application of mechanism design theory by employing the two core ideas of information and incentives and a new research methodology consisting of “three dimensions and six natures”. This book reviews and grasps China’s reform through a qualitative analysis of economic theories and an empirical analysis of statistics from a historical perspective spanning over 180 years. It is proposed to be an important reference for understanding the past, present, and future of China’s reform and teaching about the potential economic superpower. It can also serve as an essential resource for those who are interested in China's economic reform and development.
