After a general introduction into the mechanics of liquid menisci, chapters are dedicated to methods based on drops or bubbles. The chapters about the three main drop experiments provide the theoretical basis, a description of experimental set-ups, specific advantages and disadvantages, correction and calibration problems, experimental examples and their interpretation: pendent and sessile drop, drop volume, and spinning drop technique. The chapter about capillary pressure methods summarises different techniques and gives examples of applications, for instance measurements under microgravity.

The maximum bubble pressure technique as a particular capillary pressure method is described, with emphasis on the most recent developments which made this technique applicable to extremely short adsorption times, down to the range of milliseconds and less. Problems connected with aerodynamics and hydrodynamics are discussed and used to show the limits of this widely used standard method.

The oscillating bubble technique provides information not available by other techniques, for example about the dilational rheology of adsorption layers and relaxation processes at the interface.

The description of rising bubbles in surfactant solutions will contain the hydrodynamic basis as well as the theoretical description of the effect of interfacial layers on the movement of bubbles. Besides the theoretical basis experimental data, such as water purification, flotation processes etc. and the relevance for practical applications will be presented. The chapter about lung alveols demonstrates how important bubbles built by biological membranes are in everyday life. The relevance for medicine and biology as well as model studies is discussed.

An important example for the application of drops is metallurgy, where the surface tension of metals and alloys is an important parameter for many applications. The chapters on drop shape analysis by using fibre technique and on force measurements between emulsion droplets are of much practical relevance.

Lists of references and symbols are given separately at the end of each chapter while a common subject index is given at the end of the book.

This book presents a comprehensive investigation of the complex scientific principles and practical applications of emulsions, offering valuable references for researchers, industry professionals, and advanced students in the fields of physical chemistry, material sciences, and engineering. The book is structured in three sections, which allow the readers to explore the fundamental principles of interfacial phenomena, the methodologies for emulsion preparation, and the diverse applications of emulsions in various industrial branches in depth.

The initial section establishes the fundamental principles, with a particular focus on the physico-chemical characterization of interfaces pertinent to emulsion stabilization. The book meticulously examines several topics, including adsorption dynamics, particle-laden interfaces and thin liquid films. It supports these discussions with a combination of experimental techniques and theoretical insights. The second section shifts focus to the practical aspects of emulsion production, examining state-of-the-art methods, the role of stabilizers, and strategies for enhancing their stability, including innovations in nanoemulsions and aqueous two-phase systems. The final section presents several real-world applications, demonstrating the significant role that emulsions play in a number of fields, including the petroleum industry, pest control and pharmaceutical formulations.

This text, featuring contributions from leading experts, synthesizes foundational knowledge and cutting-edge research, thereby bridging the gap between theory and practice. With an interdisciplinary scope, the book addresses both academic and industrial perspectives, and is therefore an indispensable addition to the library of anyone working with emulsions. It provides the tools and understanding required to advance work in the development of new materials, optimization of formulations, and investigation of the mechanics of interfacial systems.

Innovations in Ionic Liquid-Based Surfactants and Interfacial Phenomena" offers a comprehensive exploration of ionic liquid-based surfactants (ILBSs) and their transformative potential. This book is divided into three sections. Section I establishes the fundamental properties of ionic liquids (ILs) and ILBSs, emphasizing their unique structures, environmental advantages, and flexible design. It details the diverse types of ILBSs, highlighting their individual characteristics and applications. Section II delves into the crucial interfacial behavior of ILBSs, examining their role in reducing interfacial tension, influencing micelle formation, enhancing emulsification processes, and modifying surface wettability. The mechanisms underlying these phenomena are thoroughly investigated, with particular attention paid to the impact of the structure of ILBSs on their performance. Section III showcases the broad applicability of ILBSs across various industries. Specific applications discussed include the stabilization of particle dispersions, the improvement of extraction techniques, and the significant enhancement of oil recovery from challenging reservoirs. This book bridges the gap between fundamental principles and practical applications, equipping the readers with the necessary knowledge to harness the revolutionary potential of ILBSs. It serves as an invaluable resource for researchers, academics, and professionals in this rapidly evolving field.

This book describes in detail the scientific philosophy of the formation and stabilization-destabilization of foams. It presents all hierarchical steps of a foam, starting from the properties of adsorption layers formed by foaming agents, discussing the properties of foam films as the building blocks of a foam, and then describing details of real foams, including many fields of application. The information presented in the book is useful to people working on the formulation of foams or attempting to avoid or destruct foams in unwanted situations.
