Surface tension and interfacial tension of polyolefins and polyolefin blends

Surface tension and interfacial fluctuations in d–dimensional Ising model

The surface tension of rough interfaces between coexisting phases in 2D and 3D Ising models are discussed in view of the known results and some original calculations presented in this paper. The results are summarised in a formula, which allows to interpolate the corrections to finite–size scaling between two and three dimensions. The physical meaning of an analytic continuation to noninteger v...

An Experimental Investigation of Water Effects on Asphaltene Surface Behavior through Interfacial Tension Measurements

As a physiochemical property, asphaltenes are known to be one the most surface active compounds in crude oil. Due to such property, their behavior is most probably influenced by fluid-fluid interactions at the contact surface (interface). Potentially and naturally, in most cases, water is in contact with crude oil and is co-produced with it as well. Considering that asphaltene molecules are pol...

Prediction of Surface Tension in Single and Mixed Electrolyte Solutions

Interfacial Tension of Electrolyte Solutions

A theory is presented to account for the increase in surface tension of water in the presence of electrolyte. Unlike the original “grandcanonical” calculation of Onsager and Samaras, which relied on the Gibbs adsorption isotherm and lead to a result which could only be expressed as an infinite series, our approach is “canonical” and produces an analytic formula for the excess surface tension. F...

Density and Temperature Dependencies of Liquid Surface Tension

In this paper the density and temperature dependencies of surface tension are investigated. Using the Lennard-Jones (12,6), as an effective pair interaction potential, a linear expression is derived for isotherms of g /r2  versus r2 for some normal and ChloroFluoroCarbons (CFCs)</...
