A comprehensive, practical approach to three powerful methods of polymer analysis and characterization This book serves as a complete compendium of three important methods widely used for the characterization of synthetic and natural polymers—light scattering, size exclusion chromatography (SEC), and asymmetric flow field flow fractionation (A4F). Featuring numerous up-to-date examples of experimental results obtained by light scattering, SEC, and A4F measurements, Light Scattering, Size Exclusion Chromatography and Asymmetric Flow Field Flow Fractionation takes an all-in-one approach to deliver a complete and thorough explanation of the principles, theories, and instrumentation needed to characterize polymers from the viewpoint of their molar mass distribution, size, branching, and aggregation. This comprehensive resource: Is the only book gathering light scattering, size exclusion chromatography, and asymmetric flow field flow fractionation into a single text Systematically compares results of size exclusion chromatography with results of asymmetric flow field flow fractionation, and how these two methods complement each other Provides in-depth guidelines for reproducible and correct determination of molar mass and molecular size of polymers using SEC or A4F coupled with a multi-angle light scattering detector Offers a detailed overview of the methodology, detection, and characterization of polymer branching Light Scattering, Size Exclusion Chromatography and Asymmetric Flow Field Flow Fractionation should be of great interest to all those engaged in the polymer analysis and characterization in industrial and university research, as well as in manufacturing quality control laboratories. Both beginners and experienced can confidently rely on this volume to confirm their own understanding or to help interpret their results.

As of late, greater efforts are being made in the use of nanoemulsion techniques to encapsulate, protect, and deliver functional compounds for food applications, given their advantages over conventional emulsification techniques. In addition, delivery systems of nano-scale dimensions use low-energy emulsification methods and exclude the need of any solvent, heat, or sophisticated instruments in their production. Divided into three sections, Nanoemulsions in Food Technology: Development, Characterization, and Applications will provide in-depth information and comprehensive discussion over technologies, physical and nanostructural characterization, as well as applicability of the nanoemulsion technique in food sciences. It describes the techniques involved in nanoemulsion characterization, mainly dealing with interfacial and nanostructural characterization of nanoemulsions, different physical characterization techniques, as well as various imaging and separation techniques involved in its characterization. Key Features Provides a detailed discussion about the technology of nanoemulsion Explains how nanoemulsion technique is helpful in using essential oils of different biological sources Presents methods of preparation and recent advancements in manufacturing along with stability perspectives of this technique.

This is a timely collection of important biomedical applications for a set of separation/characterization techniques that are rapidly gaining popularity due to their wide dynamic range, high resolution, and ability to function in most commonly used solvent systems. Importantly, the field-flow fractionation (FFF) technique has recently emerged as a prominent complement to size exclusion chromatography for protein pharmaceuticals. Fractionation with FFF is gentle and preserves protein structural integrity better than existing alternatives. In the present text, different chapters are written by experts in their respective field of application, who offer comparisons between the FFF techniques and other methods for characterizing their special focus material. Practical guide-lines for successful implementation, such as choice of operating conditions, are offered in conjunction with each application. In addition to new instrumentation and approaches that address important current topics, readers are provided with an overall sense of prior (but timeless) major developments that may be overlooked in literature searches.

Until quite recently conditions in industry were often rough. Long hours were worked in insanitary and murky workshops, often with little regard to the effects upon the workpeople who were considered to be expendable. Now, however, these adverse conditions have been recognized and so remedied that there remains little in industrial conditions to disturb the public conscience. This does not mean that conditions of work in office or factory are perfect. The obvious and dramatic abuses of the human frame may have gone, but in their place have arisen stresses and strains which, taking effect only in the long term, are generally undramatic and often unrecognized. They exist none the less. No organized effort to study the effect of working conditions on man's performance was made until the end of World War I, when the Industrial Fatigue Research Board was set up. For the first time, men trained in the human sciences entered industry to study men at work. They made con tributions which set a new standard of scientific investigation into human performance and allowed executive action on the basis of evidence rather than of hunch. The Board's work differed from the contribution of Gilbreth in America in that the principles of Motion Study which he developed were, to a large extent, based on intelligent observation rather than controlled experiment. During the 1920S the National Institute of Industrial Psychology was founded and there was close collaboration between it and the I.F.R.B.

Offers new strategies to optimize polymer reactions With contributions from leading macromolecular scientists and engineers, this book provides a practical guide to polymerization monitoring. It enables laboratory researchers to optimize polymer reactions by providing them with a better understanding of the underlying reaction kinetics and mechanisms. Moreover, it opens the door to improved industrial-scale reactions, including enhanced product quality and reduced harmful emissions. Monitoring Polymerization Reactions begins with a review of the basic elements of polymer reactions and their kinetics, including an overview of stimuli-responsive polymers. Next, it explains why certain polymer and reaction characteristics need to be monitored. The book then explores a variety of practical topics, including: Principles and applications of important polymer characterization tools, such as light scattering, gel permeation chromatography, calorimetry, rheology, and spectroscopy Automatic continuous online monitoring of polymerization (ACOMP) reactions, a flexible platform that enables characterization tools to be employed simultaneously during reactions in order to obtain a complete record of multiple reaction features Modeling of polymerization reactions and numerical approaches Applications that optimize the manufacture of industrially important polymers Throughout the book, the authors provide step-by-step strategies for implementation. In addition, ample use of case studies helps readers understand the benefits of various monitoring strategies and approaches, enabling them to choose the best one to match their needs. As new stimuli-responsive and "intelligent" polymers continue to be developed, the ability to monitor reactions will become increasingly important. With this book as their guide, polymer scientists and engineers can take full advantage of the latest monitoring strategies to optimize reactions in both the lab and the manufacturing plant.
