In the 20 years since the publication of the author’s multi-contributor volume on defoaming, a vast amount of new work has been published and many new insights have been revealed. A cohesive, single-authored book, The Science of Defoaming: Theory, Experiment and Applications provides comprehensive coverage of the topic. It describes the mode of action of antifoams, presenting the relevant theory and the supporting experimental evidence. Beginning with an introductory chapter that discusses the intrinsic properties of foam, the book then describes experimental methods for measuring foam properties important for studying antifoam action and techniques used in establishing the mode of action of antifoams. Since most commercially effective antifoams are oil based, a chapter is devoted to the entry and spreading behavior of oils and the role of thin film forces in determining that behavior. The book reviews the mode of action of antifoams, including theories of antifoam mechanisms and the role of bridging foam films by particles and oil drops. It also addresses issues related to the effect of antifoam concentration on foam formation by air entrainment and the process of deactivation of mixed oil–particle antifoams during dispersal and foam generation. For applications where chemical antifoam use is unacceptable, the text examines mechanical means of defoaming, such as the use of rotary devices and ultrasound. The final chapters consider the application of defoaming in radically different contexts including waterborne latex paints and varnishes, machine washing of textiles, gas–oil separation in crude oil production, and cardiopulmonary bypass surgery. Focusing on the basic science of defoaming, this book presents a balanced view, which also addresses the challenges that may arise for these specific defoaming applications.

The book Foams: Theory and Industrial Applications, written by the undersigned and three collaborators and published in 1953, is still the only monograph on liquid foam in the English language. Naturally the science of foams had advanced in the intervening years so that a practically new book had to be prepared to give justice to the present state of our know ledge. This monograph has only one author and does not deal with solid foams, fire-fighting foams, and flotation, on which information is available elsewhere. The other applications of foam and its fundamental properties are reviewed at length and, whenever possible, attempts are made to reach the truth through a maze of conflicting evidence.

The interfacial behaviour of surfactants and proteins, and their mixtures, is of importance in a wide range of areas such as food technology, detergency, cosmetics, coating processes, biomedicine, pharmacy and biotechnology. Methods such as surface and interfacial tension measurements and interfacial dilation and shear rheology characterise the relationships between these interfacial properties and the complex behaviour of foams and emulsions is established. Recently-developed experimental techniques, such as FRAP which enable the measurement of molecular mobility in adsorption layers, are covered in this volume. The development of theories to describe the thermodynamic surface state or the exchange of matter for proteins and protein/surfactant mixtures is also described. Features of this book: • Reflects the state-of-the-art research and application of protein interfacial layers rather than a snapshot of only some recent developments. • Emphasis is placed on experimental details as well as recent theoretical developments. • New experimental techniques applied to protein interfacial layers are described, such as FRAP or ADSA, or rheological methods to determine the mechanical behaviour of protein-modified interfaces. • A large number of practical applications, ranging from emulsions relevant in food technology for medical problems such as lung surfactants, to the characterisation of foams intrinsic to beer and champagne production. The book will be of interest to research and university institutes dedicated to interfacial studies in chemistry, biology, pharmacy, medicine and food engineering. Industrial departments for research and technology in food industry, pharmacy, medicine and brewery research will also find this volume of value.

Integrating fundamental research with the technical applications of this rapidly evolving field, Structure and Functional Properties of Colloidal Systems clearly presents the connections between structure and functional aspects in colloid and interface science. It explores the physical fundamentals of colloid science, new developments of synthesis and conditioning, and many possible applications. Theory Divided into three parts, the book begins with a discussion of the theoretical side of colloid dynamics. It then transitions to dynamically arrested states and capillary forces in colloidal systems at fluid interfaces. Structure Covering the structural aspects of different colloidal systems, the second section examines electric double layers and effective interactions as well as the structure of extremely bimodal suspensions and filaments made up of microsized magnetic particles. The contributors analyze the role played by the attractive interaction, confinement, and external fields on the structure of colloidal systems. They also discuss structural aspects in food emulsions and the rheological properties of structured fluids. Functional Materials The last part focuses on examples of functional colloids. These include polymer colloids, protein-functionalized colloidal particles, magnetic particles, metallic nanoparticles, micro- and nanogels, responsive microgels, colloidal photonic crystals, microfluidics, gel-glass dispersed liquid crystals (GDLCs) devices, and nanoemulsions. This volume provides a sound understanding of the link between the structure and functional properties in two- and three-dimensional colloidal systems. It describes techniques to functionalize colloids, characterization methods, the physical fundamentals of structure formation, diffusion dynamics, transport properties in equilibrium, the physical fundamentals of nonequilibrium systems, the measuring principles to exploit properties in applications, the differences in designing lab experiments and devices, and several application examples.

This textbook is designed to provide the theory, methods of measurement, and principal applications of the expanding field of interfacial hydrodynamics. It is intended to serve the research needs of both academic and industrial scientists, including chemical or mechanical engineers, material and surface scientists, physical chemists, chemical and biophysicists, rheologists, physiochemical hydrodynamicists, and applied mathematicians (especially those with interests in viscous fluid mechanics and continuum mechanics). As a textbook it provides materials for a one- or two-semester graduate-level course in interfacial transport processes. It may also be noted that, while separate practical and theoretical subdivisions of material have been introduced, a kind of cross-emphasis is often stressed: (i) to the academic scientist, or the importance of understanding major applications of interfacial transport; and (ii) to the industrial scientist, of the importance of understanding the underlying theory.

Emulgatoren sind Gegenstand vieler Untersuchungen, technischen und wissenschaftlichen Berichten, Ubersichtsartikeln und Biichern. Auch in der lebensmitteItechnologischen Literatur werden Emulgatoren, wenn auch in unterschiedlichem AusmaB, behandelt. Ich kenne allerdings kein Buch, das wie das vorliegende in so ausgezeichneter Weise die Zusammensetzung, die Aufgaben und die funktionellen Eigenschaften der bei der Herstellung von Lebensmitteln verwendeten Emulgatoren beschreibt. Theorie und Praxis werden gleichermaBen grundlegend behandelt. Was aber die Darstellung so einzigartig und niitzlich macht, ist die gelungene Verbindung von theoretischem Wissen und praktischer Anwendung. Obwohl dieses Buch von mehreren Autoren verfaBt wurde, spiirt man in jedem Kapitel die Liebe des Herausgebers, Autors und Mitautors von 10 der insgesamt 13 Kapitel, die das ganze Buch durchdringt. Seine Handschrift ist in der gelungenen Planung und versHindlichen Darstellung zu erkennen, in der Verbindung zwischen Wissenschaft und Praxis und in dem Zusammen fUgen der neuesten Ergebnisse mit weitreichenden Hintergrundinformationen; dies ist nur jemandem moglich, der die Theorie iiberpriift und die Ergebnisse in die Praxis umgesetzt hat. Die lenkende Hand des Herausgebers erkennt man aber auch im einheitlichen Stil der Darstellung, der durch die zahl reichen Illustrationen, Tabellen und Kurven ausgezeichnet erganzt wird. Die ausgewahlte, umfangreiche Literaturzusammenstellung weist auf die wich tigsten Quellen hin und erlaubt dem Leser die ErschlieBung zusatzlicher aus fiihrlicher Informationen. Beim Verfassen eines Buches iiberlegt sich der Autor oft, ob der Aufwand beim Schreiben in angemessenem Verhaltnis zum erreichbaren Ergebnis steht.
