Most modern surfactants are readily biodegradable and exhibit low toxicity in the aquatic environment, the two criteria for green surfactants. However the majority are synthesised from petroleum, so over the past decade the detergent industry has turned its attention to developing greener routes to create these surfactants via renewable building blocks. Surfactants from Renewable Resources presents the latest research and commercial applications in the emerging field of sustainable surfactant chemistry, with emphasis on production technology, surface chemical properties, biodegradability, ecotoxicity, market trends, economic viability and life-cycle analysis. Reviewing traditional sources for renewable surfactants as well as recent advances, this text focuses on techniques with potential for large scale application. Topics covered include: Renewable hydrophobes from natural fatty acids and forest industry by-products Renewable hydrophiles from carbohydrates, amino acids and lactic acid New ways of making renewable building blocks; ethylene from renewable resources and complex mixtures from waste biomass Biosurfactants Surface active polymers This book is a valuable resource for industrial researchers in companies that produce and use surfactants, as well as academic researchers in surface and polymer chemistry, sustainable chemistry and chemical engineering.

The co-evolution of a strong theoretical framework alongside application of a range of sophisticated experimental tools engendered rapid advancement in the study of “giant micelles.” Beginning with Anacker and Debye’s 1951 experimental study of elongated micelles by light scattering and their subsequent theoretical inference that the thermodynamics of these structures would have to reflect an opposing force model, theory and experiment have progressed hand in hand. This progress, along with growing interest in the practical and industrial applications of these structures in cleansers, cosmetics, pharmaceuticals, and energy production, demands a comprehensive, single-source reference to the current state-of-the-science. Drawing on the expertise of internationally known scientists, Giant Micelles: Properties and Applications summarizes the range of behaviors encountered in solutions of micelles and their applications in industrial processes. The book introduces theoretical aspects of the rheological behavior and formation of giant micelles from different viewpoints including molecular-level thermodynamic theory and computer simulations. It continues by focusing on the results of a variety of experimental studies using methods such as cryo-transmission electron microscopy, scattering techniques, phase diagrams, linear and non-linear rheology, and chemical relaxation. Illustrating the properties of giant micelles on solid surfaces, the book also considers systems of smart micelles that respond to external stimuli by a change of shape. The authors describe giant micelles formed from amphiphilic block copolymers as well as non-covalent polymers that exhibit similar rheological behavior to giant micelles. Finally, the chapters address current and emerging applications of giant micelles in oil and gas production, drag reduction, drug-delivery formulations, and personal care products such as shampoo. By gathering a range of information into one volume, Giant Micelles: Properties and Applications provides scientists with an essential reference on these fascinating materials and their emerging role in industrial application.

Die Grundlagen und Methoden, die zur theoretischen Modellierung und zur Analyse von Strömungsvorgängen mit nicht-newtonschen Fluiden erforderlich sind, werden in diesem Lehrbuch vorgestellt. Zunächst werden die kinematischen, die kontinuumsmechanischen und die stofflichen Grundlagen ausführlich erläutert. Die Anwendung des Basiswissens erfolgt exemplarisch anhand ausgewählter Strömungsvorgänge, die maßgeblich von den nichtlinearen Fließeigenschaften, von den Normalspannungsdifferenzen oder vom Gedächtnis der Flüssigkeiten beeinflusst werden. Dabei haben sich die Inhalte, die Schwerpunkte und die Beispiele gegenüber der ersten Auflage wesentlich geändert. Erstmalig in einem deutschsprachigen Lehrbuch werden auch die Grundzüge einer numerischen Strömungssimulation unter Berücksichtigung komplexer rheologischer Stoffmodelle behandelt.
