Request a sales quoteInterfacial Phenomena explores the more primary properties of different liquid interfaces. This book is divided into eight chapters, where Chapter 1 establishes the basic concepts of the physics of surfaces, including the properties of matter in the surface layer. Chapters 2 and 3 further discuss the concepts of electrostatic and electrokinetic phenomena, respectively. Other areas discussed in the later chapters include adsorption at liquid interfaces; properties of monolayers; reactions at liquid interfaces; and mass transfer across interfaces. Chapter 8 discusses the more relevant aspects of disperse systems and adhesion as related to the interfacial properties discussed in the previous chapters. The text is a valuable source of information to students and researchers in the fields of chemistry, biology, and chemical engineering and can also be used for industrial and academic laboratories.
