  • The feature of polyimides and other heterocyclic polymers are now well-established and used for long term temperature durability in the range of 250 - 350'C. This book will review synthesis, mechanisms, ultimate properties, physico-chemical properties, processing and applications of such high performance materials needed in advanced technologies. It presents interdisciplinary papers on the state of knowledge of each topic under consideration through a combination of overviews and original unpublished research.

  • The field of toxicology has grown enormously since Industrial Toxicology: Safety and Health Applications in the Workplace was first published in 1985. And while the original edition was hugely popular among occupational health professionals, the time is ripe to address toxic agents not only in the industrial setting but also in the environment at large.

  • Distillation is probably one of the oldest systematic processes in the field of chemistry and chemical engineering which goes back to the first century AD. The initial concepts were applied in the production of distilled water. Distillation was a single step batch process at the beginning. However, fractional distillation as is used today was developed more than 10 centuries later.

  • "Under the right conditions and applications, evaporative air-conditioning (EAC) technologies can provide excellent cooling and ventilation with minimal energy consumption." Evaporative air-conditioning technologies are being used increasingly in residential and commercial applications worldwide. EAC technologies, which rely on water as a coolant rather than on chemical refrigerants, are economical to produce and use and have important environmental benefits.

  • The terms “cosmetic tattooing” or “permanent makeup” (e.g. micropigmentation) refer to mechanical application of pigmented materials to the area of the eye, lips and face for the purpose of changing the color or appearance of that facial feature. This is a rapidly growing business in the United States becoming mainstream in many sociological circles.

  • It is traditional to begin books about polyurethanes by defining the class of polymers that has come to be known as polyurethanes. Unlike olefin-based polymers (poly- ethylene, polypropylene, etc.), the uniqueness of polyurethane is that it results not from a specific monomer (ethylene, propylene, etc.), but rather from a type of reaction, specifically the formation of a specific chemical bond. Inevitably, the discussion in traditional books then progresses to the component parts, the produc- tion processes, and ultimately the uses.

  • This Second Edition of the go-to reference combines the classical analysis and modern applications of applied mathematics for chemical engineers. The book introduces traditional techniques for solving ordinary differential equations (ODEs), adding new material on approximate solution methods such as perturbation techniques and elementary numerical solutions. It also includes analytical methods to deal with important classes of finite-difference equations. The last half discusses numerical solution techniques and partial differential equations (PDEs). The read...

  • Using an applications perspective Thermodynamic Models for Industrial Applications provides a unified framework for the development of various thermodynamic models, ranging from the classical models to some of the most advanced ones. Among these are the Cubic Plus Association Equation of State (CPA EoS) and the Perturbed Chain Statistical Association Fluid Theory (PC-SAFT). These two advanced models are already in widespread use in industry and academia, especially within the oil and gas, chemical and polymer industries....

  • Biocide dosing itself, paper machine breaks, and poor management of broke generated chemical variations, which were detrimental to the papermaking process. Spoilage of broke due to poor broke management and poor biocide performance decreased the system pH, increased the conductivity, and caused the defects to the web. These chemical variations were also observed to cause variations in the cationic demand values. This probably caused unwanted particle flocculation generating the spots and holes to the web.

  • Agriculture and forestry are poised on the brink of a quantum leap forward through the further application of exciting new tools such as genomics and transgenic plants. In the near future, it will be possible to produce a higher quantity of improved quality crops than even imagined just a few years ago.  In addition to feed and food, it will be possible to provide raw materials for industrial uses. For example, cotton fibers, wood ligno-celluloses, corn  carbohydrates, soybean oils, and other plant constituents will be altered via designed changes in metabolic pathways.
