Surface Tension of Pure Liquids and Binary Liquid Mixtures


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.




Surface Tension of Pure Liquids and Binary Liquid Mixtures


Book Description

Surface tension of liquids determine fundamental chemical and physical properties and applications. Cleansing agents, soldering agents, pharmalogical substances and biomechanical phenomena all rely on surface tensions and their deliberate modifications, so that a collection of reliable data will be of interest for users in science, research and engineering. This supplement volume contains surface tensions of non-electrolyte material systems, as well as surface tensions data of pure liquids and binary liquid mixtures at normal temperatures.




Tables of Neutron Resonance Parameters (Supplement to Subvolume B)


Book Description

Parameters of neutron resonances play a significant role both in basic physics, but even more so for applications. For the understanding of astrophysical processes neutron cross sections in particular at low energies are indispensable. For practical applications precise neutron data are becoming more important be it for the design of new nuclear reactors, for waste transmutation or the newly considered Thorium – Uranium cycle. This volume provides an update of data published in volumes 16B. Since their publication several years have elapsed and new data have become available. Their quality and precision has been considerably improved by the operation of new neutron spectrometers, in particular GELINA, a time-of-flight facility to which a whole chapter is devoted. The data are presented in the same format as in the previous volumes. In addition to the neutron resonance parameters the parameters of the subsequent gamma-rays are also included. Since the total amount of data is very large only the parameters of the most important resonances (at low energies) could be included in the printed version whereas the data for resonances at higher energies are contained on the CD-ROM as Supplement. Again a considerable effort was made in comparing data from different sources in order to establish ‘best values’, one of the main characteristics of Landoldt- Börnstein publications.




Rheology and Dynamics of Simple and Complex Liquids in Mesoporous Matrices


Book Description

Subject of my thesis is a study of rheologic and dynamic properties of fluids confined in an isotropic pore network with pore radii of approx. 5nm embedded in a monolithic silica matrix (porous Vycor). The experimental technique bases on the capillary rise of a wetting liquid in a porous substrate, also known as spontaneous imbibition. A crucial part of the conducted experiments centers on the increasing relevance of the liquid-substrate interface in the mesopore confinement. Detailed analyses of the measurements carried out with water, silicon oils, and a series of hydrocarbons result in precise information on the boundary conditions expressed in terms of the velocity slip length. Systematic variations of the chain-length of the used hydrocarbons also allow for an assessment of the influence of the shape of the liquid's building blocks on the nanoscopic flow behavior. Supplemental forced throughput experiments additionally address the impact of the liquid-substrate interaction. Furthermore, the influences of spatial confinement on the surface freezing transition of the linear hydrocarbon n-tetracosane as well as on the mesophase transitions of the liquid crystal 8OCB are investigated. Finally, a third, more general study focuses on the kinetics of the invasion front, which is supposed to be influenced significantly by the random environment of the pore space considered.

The Thermophysical Properties of Metallic Liquids


Book Description

This first volume provides the basic matters needed for understanding the thermophysical properties of metallic liquids and for developing reliable models to accurately predict the thermophysical properties of almost all metallic elements in the liquid state, together with methods for quantitative assessment of models/equations. The authors also review the structure of metallic liquids, which is based on the theory of liquids, density, volume expansivity, thermodynamic properties (evaporation enthalpy, vapour pressure, heat capacity), sound velocity, surface tension, viscosity, diffusion, and electrical and thermal conductivities. Finally, the essential points of methods used for measuring these experimental data are presented.
