DIVOver 25 unique effects illustrated with process photos, finished examples, and variations. Mixed Emulsions is a follow up to Karen Michel's book, The Complete Guide to Altered Imagery. Mixed Emulsions: Altered Art Techniques for Photographic Imagery takes a slightly different tact, bringing traditional and digital photography front and center, showing the many ways that photographic imagery can be manipulated, not electronically, but using various art materials and techniques. The chapters explore ways to add color (paints, oil sticks, watercolors, inks), ways to add texture (embossing powders, gessos, pastes, wax), and special effects (printing on unusual substrates, imprinting, photo mosaics, using tissue, fabric, cardboard). Altered art continues to grow as an area of interest for many kinds of crafters. A great technique book for artists looking to expand the creative possibilities for altered photography A gallery of artwork by other well-known artists offers further inspiration /div

Emulsions (simple, mixed or multiple) are essentially pure substances, aqueous or organic binary solutions. The have a wide range of uses, including industrial cooling and heat transfer processes. This monograph gives a brief overview of supercooling, crystallization and melting processes within emulsions. Differential scanning calorimetrey (DSC) coupled with RX is the main technique used to demonstrate these processes. Temperature readings in this work have been defined taking into account known nucleation laws. These results have been used to show mass transfers occurring within mixed emulsions (solid ripening) or multiple emulsions (composition ripening), gas hydrate formation due to a chemical reaction between water and a diffuse specific compound, these phenomena being described by diffusive models. Other aspects of heat transfer process covered in this book include the latent energy released at crystallizations or absorbed at the melting (which alters the temperature field through emulsions), the kinetics of phase transformations and self-regulation of temperature in nodules containing phase changing materials. This monograph is intended for advanced chemistry graduates as well as industrial and chemical engineers working with cooling and heat transfer systems.

Surfactants are surface active agents, molecules that have a significant role in emulsions, suspensions, and foams. They find widespread application in personal care, cosmetics, pharmaceuticals, agrochemicals and the food industry. Their classification, physical properties, phase behavior, their effects and applications are covered in this book.

This second edition has been designed to monitor the progress in develop ment over the past few years and to build on the information given in the first edition. It has been extensively revised and updated. My thanks go to all who have contributed to this work. D.F.W. May 1996 Preface to the first edition This book is the result of a group of development scientists feeling that there was an urgent need for a reference work that would assist chemists in understanding the science involved in the development of new products. The approach is to inform in a way that allows and encourages the reader to develop his or her own creativity in working with marketing colleagues on the introduction of new products. Organised on a product category basis, emphasis is placed on formulation, selection of raw materials, and the technology of producing the products discussed. Performance considerations, safety, product liability and all aspects of quality are covered. Regulations governing the production and sale of cosmetic products internationally are described, and sources for updated information provided. Throughout the book, reference is made to consumer pressure and environmental issues-concerns which the development scientist and his or her marketing counterpart ignore at their own, and their employer's peril. In recent years, many cosmetic fragrances and toiletry products have been converted from aerosols to mechanically press uri sed products or sprays, and these are described along with foam products such as hair conditioning mousses.

Theory and Practice of Emulsion Technology covers the proceedings of the Theory and Practice of Emulsion Technology Symposium, held at Brunel University on September 16-18, 1974. This book is organized into four sessions encompassing 19 chapters. The opening session deals with the emulsification process and emulsion polymerization, as well as the adsorption behavior of polyelectrolyte-stabilized emulsions. The following session examines the rheological properties, stability, and fluid mechanics of emulsions. This session also looks into the role of protein conformation and crude oil-water interfacial properties in emulsion stability. The third session highlights the preparation, formation, properties, and application of bitumen emulsions. The concluding session describes the process of spontaneous emulsification; the steric emulsion stabilization; the interfacial measurements of oil-in-water emulsions; and the influence of the disperse phase on emulsion stability. This book will be of value to chemists, chemical and process engineers, and researchers.
