A series of concurrent pressures in the early 2000s-climate change, financial system crashes, economic development in rural regions, and shifts in geopolitics-intensified interest in alternative energy production. At the same time, rising oil prices rendered alternative fuels a more economically viable option. Among these energy sources, liquid biofuels (bioethanol and biodiesel) and natural gas derived from hydraulic fracturing ("fracking") took center stage as promising commodities and technologies. But controversy quickly erupted in surprisingly similar ways around both renewable fuels. Global enthusiasm for these fuels-and the widespread projections for their production around the world-collided with local politics in debates over "food versus fuel" and concerns over "land grabs." What seemed, from a global perspective, like empty lands ripe for development were, to rural communities, vibrant and already contested spaces. As proposals for biofuels and fracking landed in specific communities and ecosystems, they reignited and reshaped old disputes over land, water, and decision-making authority. Fueling Resistance offers an account of how and why controversies over these different fuels unfolded in surprisingly similar ways in the global North and South. To explain these convergent dynamics of contention and resistance, Kate J. Neville argues that the emergence of grievances and the patterns of resistance to new fuel technologies depends less on the type of energy developed (renewable versus fossil fuel) than on intersecting elements of the political economy of energy: finance, ownership, and trade relations. As local commodities enter global supply chains and are integrated into existing corporate structures, opportunities arise to broker connections between otherwise disparate communities. Neville looks at biofuels in Kenya and fracking in the Canadian Yukon and shows how organizers connect specific energy projects to broader issues of globalization, climate, food, water, and justice. Taken together, the intersecting elements of the political economy of energy shape the contentious politics of biofuels and fracking at both local and global scales, and help explain how and why particular mechanisms of contention emerge at different times and places.

3D industrial printing has become mainstream in manufacturing. This unique book is the first to focus on polymers as the printing material. The scientific literature with respect to 3D printing is collated in this monograph. The book opens with a chapter on foundational issues such and presents a broad overview of 3D printing procedures and the materials used therein. In particular, the methods of 3d printing are discussed and the polymers and composites used for 3d printing are detailed. The book details the main fields of applications areas which include electric and magnetic uses, medical applications, and pharmaceutical applications. Electric and magnetic uses include electronic materials, actuators, piezoelectric materials, antennas, batteries and fuel cells. Medical applications are organ manufacturing, bone repair materials, drug-eluting coronary stents, and dental applications. The pharmaceutical applications are composite tablets, transdermal drug delivery, and patient-specific liquid capsules. A special chapter deals with the growing aircraft and automotive uses for 3D printing, such as with manufacturing of aircraft parts and aircraft cabins. In the field of cars, 3D printing is gaining importance for automotive parts (brake components, drives), for the fabrication of automotive repair systems, and even 3D printed vehicles.

This textbook covers the fundamentals of physical chemistry, explaining the concepts in an accessible way and guiding the readers in a step-by-step manner. The contents are broadly divided into two sections: the classical physico-chemical topics (thermodynamics, kinetics, electrochemistry, transport, and catalysis), and the fabric of matter and its interactions with radiation. Particular care has been taken in the presentation of the algebraic parts of physico-chemical concepts, so that the readers can easily follow the explanations and re-work relevant discussion and derivations with pen and paper. The book is accompanied by a rich mathematical appendix. Each chapter includes a selection of (numerical) exercises and problems, so that students can practice and apply the learned topics. An appendix with solutions allows for controlling the learning success. Carefully prepared illustrative color images make this book a great support for teaching physical chemistry to undergraduate students.This textbook mainly addresses undergraduate students in life sciences, biochemistry or engineering, offering them a comprehensive and comprehensible introduction for their studies of physical chemistry. It will also appeal to undergraduate chemistry students as an accessible introduction for their physical chemistry studies.

This is the second volume of a two-volume work devoted to probability theory in physical chemistry, and engineering. Rather than dealing explicitly with the idea of an ongoing random walk, with each chaotic step taking place at fixed time intervals, this volume addresses random environments-- models in which the disorder is frozen in space. It begins with an introduction to the geometry of random environments, emphasizing Bernoulli percolation models. The scope of the investigation then widens as we ask how structural disorder affects the transport process. The final chapters confront the interplay of two different forms of randomness; spatial randomness frozen into the environment and temporal randomness associated with the choices for next steps made by a random walker. The book ends with a discussion of "the ant in the labyrinth" problems and an extensive bibliography that, along with the rest of the material, will be of value to researchers in physics, mathematics, and chemical engineering.

Alginate is a hydrophilic, biocompatible, biodegradable, and relatively economical polymer generally found in marine brown algae. The modification in the alginate molecule after polymerization has shown strong potential in biomedical, pharmaceutical and biotechnology applications such as wound dressing, drug delivery, dental treatment, in cell culture and tissue engineering. Besides this, alginates have industrial applications too in the paper and food industries as plasticizers and additives. The few books that have been published on alginates focus more on their biology. This current book focuses on the exploration of alginates and their modification, characterization, derivatives, composites, hydrogels as well as the new and emerging applications.
