The human immune system is constantly exposed to chemical contaminants, whether from food, water or air. Some chemicals directly elicit an immune response, while others indirectly activate or deactivate components within the immune system. Thus when tracking or predicting the effect of a chemical on the immune system, many different pathways and modes of action need to be considered. Following an introduction to the various pathways and toxicity mechanisms from a systemic perspective, the main part of this comprehensive reference surveys individual molecular mechanisms of important immunotoxicants, from PAHs to biopharmaceuticals, and from receptor-mediated toxicity to nanoparticle toxicity, using analyses based on molecular effects rather than on animal models. Taken together, the knowledge presented here provides an up-to-date overview of this hot topic that can be directly applied to the prediction and characterization of immunotoxic effects in drugs, chemicals, and environmental contaminants.

Nanomaterials are defined as materials in which at least one length dimension is below 100 nanometers. In this size regime, these materials exhibit particular – and tunable – optical, electrical or mechanical properties that are not present at the macro-scale. This opens up the possibility for a plethora of applications at the interface of materials, chemistry, physics and biology, many of which have already entered the commercial realm. When nanomaterials are blended with other materials not necessarily in the nanometer regime, the resulting nanocomposites can exhibit dramatically different properties than the bulk material alone, leading to an enhanced performance in terms of, for example, increased thermal and mechanical stability. This book presents the synthesis, characterization and applications of nanomaterials and nanocomposites, covering zero-dimensional, elemental nanoparticles, one-dimensional materials such as nanorods and nanowhiskers, two-dimensional materials such as graphene and boron nitride as well as three-dimensional materials such as fullerenes, polyhedral oligomers and zeolites, complemented by bio-based nanomaterials, e.g., cellulose, chitin, starch and proteins. Introductory chapters on the state-of-the-art of nanomaterial research and the chemistry and physics in nanoscience and nanotechnology round off the book.

This is a unique book with nearly 1000 problems and 50 case studies on open-ended problems in every key topic in chemical engineering that helps to better prepare chemical engineers for the future. The term «open-ended problem» basically describes an approach to the solution of a problem and/or situation for which there is not a unique solution. The Introduction to the general subject of open-ended problems is followed by 22 chapters, each of which addresses a traditional chemical engineering or chemical engineering-related topic. Each of these chapters contain a brief overview of the subject matter of concern, e.g., thermodynamics, which is followed by sample open-ended problems that have been solved (by the authors) employing one of the many possible approaches to the solutions. This is then followed by approximately 40-45 open-ended problems with no solutions (although many of the authors’ solutions are available for those who adopt the book for classroom or training purposes). A reference section is included with the chapter’s contents. Term projects, comprised of 12 additional chapter topics, complement the presentation. This book provides academic, industrial, and research personnel with the material that covers the principles and applications of open-ended chemical engineering problems in a thorough and clear manner. Upon completion of the text, the reader should have acquired not only a working knowledge of the principles of chemical engineering, but also (and more importantly) experience in solving open-ended problems. What many educators have learned is that the applications and implications of open-ended problems are not only changing professions, but also are moving so fast that many have not yet grasped their tremendous impact. The book drives home that the open-ended approach will revolutionize the way chemical engineers will need to operate in the future.

This new volume provides a timely study on the environmental challenges from a specific class of perfluorinated chemical compounds (PFCs) that are now being recognized as a worldwide health threat. Recent studies report that levels of classes of PFCs known as polyfluoroalkyl and perfluoroalkyl (PFASs) exceed federally recommended safety levels in public drinking-water supplies for 6 million people in the United States and that as many as 100 million people could be at risk from exposure to these chemicals. These chemicals occur globally in wildlife and humans. Both PFCAs and PFSAs have been produced for more than 50 years, but have only become of interest to regulators and environmentalists since the late 1990s. Recent advances in analytical methodology has enabled widespread detection in the environment and humans at trace levels. These toxic chemicals have been found in outdoor and indoor air, surface and drinking water, house dust, animal tissue, human blood serum, and human breast milk. Of great concern to communities is the presence of these compounds in a number of drinking water supplies in the U.S. and other countries. This new volume provides a timely explanation of the chemicals, provides a detailed review of the regulations both in the US and European Community, explains the health risk literature, and then explores in great detail available treatment technologies. The volume is a must for public water supply facilities, industrial operations that have historically used these chemicals and face legacy pollution issues, policy makers and the general public.
