Book Description
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.

Book Description
Surface Chemistry Theory and Applications focuses on liquid-gas, liquid-liquid, solid-gas, solid-liquid, and solid-solid surfaces. The book first offers information on liquid-gas surfaces, including surface tension, measurement of surface tension, rate of capillarity rise, capillary attraction, bubble pressure and pore size, and surface tension and temperature. The text then ponders on liquid-liquid and solid-gas surfaces. Discussions focus on surface energy of solids, surface roughness and cleanness, adsorption of gases and vapors, adsorption hysteresis, interfacial tension, and interfacial tension in multicomponent systems. The manuscript takes a look at solid-liquid surfaces, as well as stagnant layers at solid-liquid interfaces, heat transfer, surface roughness or electrodes, adsorption of liquids heat of wetting, and thin metal films condensed from vapor. The text also examines solid-liquid-gas and solid-liquid-liquid surfaces and electric surface phenomena. The book is a vital source of information for readers interested in surface chemistry.

Book Description
A simple and accurate technique has been developed for measuring dynamic surface tension. The new technique is based on growing a drop at the end of a fine capillary into another immiscible fluid and can follow the changes in tension at a freshly formed interface during its entire period of evolution. When the relative importance of the surface tension force is large compared to gravitational and viscous forces, shapes of growing drops are sections of spheres and the difference in pressure between the interior and the exterior of the drop {triangle}p is related to the surface tension [sigma] and the radius of curvature R by the static Young-Laplace formula {triangle}p = 2[sigma]/R. In contrast to related work, the new technique can determine the surface tension of an interface with a surface age of a few to tens of milliseconds by measuring transient drop shapes and pressures in 1/6 to 1 millisecond. The capabilities of the new method are demonstrated by performing tension measurements on liquid systems that do not exhibit dynamic surface tension as well as ones that exhibit significant dynamic tension effects. Tension measurements made with surfactant-laden solutions show that variation of surface tension is nonmonotonic in time. In such systems, the dynamic behavior of surface tension is shown to depend upon both the rate of interfacial dilatation and that of surfactant transport. A maximum in the surface tension is attained when the lowering of the surfactant concentration on the drop interface due to its dilatation is balanced by the addition of fresh surfactant to the interface by convection and diffusion.

Book Description
The COSMO-RS technique is a novel method for predicting the thermodynamic properties of pure and mixed fluids which are important in many areas, ranging from chemical engineering to drug design. COSMO-RS, From Quantum Chemistry to Fluid Phase Thermodynamics and Drug Design is about this novel technology, which has recently proven to be the most reliable and efficient tool for the prediction of vapour-liquid equilibria. In contrast to group contribution methods, which depend on an extremely large number of experimental data, COSMO-RS calculates the thermodynamic data from molecular surface polarity distributions, resulting from quantum chemical calculations of the individual compounds in the mixture. In this book, the author cleverly combines a vivid overview of the partly demanding theoretical steps with a deeper analysis of their scientific background and justification. Aimed at theoretical chemists, computational chemists, physical chemists, chemical engineers, thermodynamicists as well as students,academic and industrial experts, COSMO-RS, From Quantum Chemistry to Fluid Phase Thermodynamics and Drug Design provides a novel viewpoint to anyone looking to gain more insight into the theory and potential of the unique method, COSMO-RS. The only book currently available on COSMO-RS technique Provides a novel viewpoint for the scientific understanding and for the practical quantitative treatment of fluid phase thermodynamics Includes illustrative examples of the COSMOtherm program
