The term "surface tension" reflects the nature of intermolecular forces in neighboring liquid and vapor phases. Surface tension decreases with increasing temperature, and drops to zero value at critical temperature. To a small extent, it is influenced by pressure and the interface curvature.An Introduction to Surface Tension discusses the possibility of a significant use of surfactants, polymers, alkali and microbes for surface tension alteration based on work done in the last decades, with new insight on the chemical aspects, especially for gas recovery from shale by altering surface tension.In closing, the authors propose a model based on the concept that surfactant and polymer molecules rotate during the process reaching the equilibrium surface state, which is different from the conventional adsorption theory.

This book gives the reader an introduction to the field of surfactants in solution as well as polymers in solution. Starting with an introduction to surfactants the book then discusses their environmental and health aspects. Chapter 3 looks at fundamental forces in surface and colloid chemistry. Chapter 4 covers self-assembly and 5 phase diagrams. Chapter 6 reviews advanced self-assembly while chapter 7 looks at complex behaviour. Chapters 8 to 10 cover polymer adsorption at solid surfaces, polymers in solution and surface active polymers, respectively. Chapters 11 and 12 discuss adsorption and surface and interfacial tension, while Chapters 13- 16 deal with mixed surfactant systems. Chapter 17, 18 and 19 address microemulsions, colloidal stability and the rheology of polymer and surfactant solutions. Wetting and wetting agents, hydrophobization and hydrophobizing agents, solid dispersions, surfactant assemblies, foaming, emulsions and emulsifiers and microemulsions for soil and oil removal complete the coverage in chapters 20-25.

This book describes how surface tension effects can be used by engineers to provide mechanical functions in miniaturized products (1 mm). Even if precursors of this field such as Jurin or Laplace already date back to the 18th century, describing surface tension effects from a mechanical perspective is very recent.brThe originality of this book is to consider the effects of capillary bridges on solids, including forces and torques exerted both statically and dynamically by the liquid along the 6 degrees-of-freedom.brIt provides a comprehensive approach to various applications, such as capillary adhesion (axial force), centering force in packaging and micro-assembly (lateral force) and recent developments such as a capillary motor (torque).

Surfaces are often held to be of lesser consequence than 'deeper' or more 'substantive' aspects of artworks and objects. Yet it is also possible to conceive of the surface in more positive terms: as a site where complex forces meet. Surfaces can be theorized as membranes, protective shells, sensitive skins, even thicknesses in their own right. The surface is not so much a barrier to content as an opportunity for encounter: in new objects, the surface is the site of qualities of finish, texture, the site of tactile interaction, the last point of contact between object and maker, and the first point of contact between object and user. Surface Tensions includes sixteen essays that explore this theoretically uncharted terrain. The subjects range widely: domestic maintenance; avant-garde fashion; the faking of antiques; postmodern architecture and design; contemporary film costume. Of particular emphasis within the volume are textiles, which are among the most complex and culturally rich materialisations of surface. As a whole, the book provides insights into the whole lifecycle of objects, not just their condition when new.

1 Introduction Data extract from Landolt-Börnstein IV/24: Surface Tension of Pure Liquids and Binary Liquid Mixtures 1.1 Selection of data This supplement updates Landolt-Börnstein's New Series Group IV (Physical Chemistry) Volume 16, S- face Tension of Pure Liquids and Binary Liquid Mixtures, published in the year 1997 [1997WOH1]. The update provides experimental data published in the years 1997 to 2006. The ?nal date for including data was December, 31st, 2006. Specialization and selection of data for this new update follows the intentions of the original volume. The focus is on non-electrolyte systems, and only data for pure liquids and binary liquid mixtures at normal pr- sure (or in some single cases at saturation vapor pressure) were taken into account for this volume. For m- tures, this data collection is restricted to binary liquid mixtures, i.e. no ternary systems and also no solutions of any solids, salts, electrolytes, polymers are included here. Surfactant solutions or micellar systems in water or other ?uids were not considered either. At least, also molten metals and metallic alloys, molten salts, molten glasses and other high-temperature melts were not taken into account. As the amount of data collected between 1997 and 2006 exceeds the available space for printing by far, the volume has an electronic version containing additional data which is available on www.landolt-boernstein.

Surface tension provides a thermodynamic avenue for analyzing systems in equilibrium and formulating phenomenological explanations for the behavior of constituent molecules in the surface region. While there are extensive experimental observations and established ideas regarding desorption of ions from the surfaces of aqueous salt solutions, a more successful discussion of the theory has recently emerged, which allows the quantitative calculation of the distribution of ions in the surface region. Surface Tension and Related Thermodynamic Quantities of Aqueous Electrolyte Solutions provides a detailed and systematic analysis of the properties of ions at the air/water interface. Unifying older and newer theories and measurements, this book emphasizes the contributions of simple ions to surface tension behavior, and the practical consequences. It begins with a general discussion on Gibbs surface thermodynamics, offering a guide to his theoretical insight and formulation of the boundary between fluids. The text then discusses the thermodynamic formulae that are useful for practical experimental work in the analysis of fluid/fluid interfaces. Chapters cover surface tension of pure water at air/water and air/oil interfaces, surface tension of solutions and the thermodynamic quantities associated with the adsorption and desorption of solutes, and surface tension of simple salt solutions. They also address adsorption of ions at the air/water interface, surface tension of solutions and the effect of temperature, adsorption from mixed electrolyte solutions, and thermodynamic properties of zwitterionic amino acids in the surface region. Focusing on the thermodynamic properties of ions at air/fluid interfaces, this book gives scientists a quantitative, rigorous, and objectively experimental methodology they can employ in their research.

"Theoretical Fluid Mechanics' has been written to aid physics students who wish to pursue a course of self-study in fluid mechanics. It is a comprehensive, completely self-contained text with equations of fluid mechanics derived from first principles, and any required advanced mathematics is either fully explained in the text, or in an appendix. It is accompanied by about 180 exercises with completely worked out solutions. It also includes extensive sections on the application of fluid mechanics to topics of importance in astrophysics and geophysics. These topics include the equilibrium of rotating, self-gravitating, fluid masses; tidal bores; terrestrial ocean tides; and the Eddington solar model."--Prové de l'editor.
