TL;DR: In this paper, the authors analyzed the behavior of surface tensions in binary mixtures using the Extended Langmuir (EL) model, and the interpretation of the ratio of molar volume to molar refraction V/R as a measure of the degree of free volume appears to be a useful tool for qualitative considerations concerning volumetric and refractometric data.

TL;DR: In this paper, a new model for describing the surface tension of binary liquid mixtures as a function of the bulk composition over the whole concentration range is presented, which generalizes the Langmuir isotherm so as to cover the entire range of concentrations.

TL;DR: In this paper, the surface tension of aqueous solutions of diethanolamine (DEA), as a function of concentration, in the range 293-363 K, and of methyldiethanolamines (MDEA) at 323.15k, at different concentrations of MDEA and DEA.

TL;DR: In this paper, the aqueous binary solutions of partially miscible 2-methyl-1-propanol, cyclopentanone, cyclohexanone and ethyl acetoacetate were determined at the temperature of 298.15 K and atmospheric pressure over the mole fraction range reaching the solubility limit in the aaqueous phase.

TL;DR: In this article, the Young-Laplace general equation for curved surfaces under the influence of a centrifugal field and its relation with the spinning drop method is discussed, and it is found that Vonnegut's expression may be regarded as a particular case of the general curvature equation and that the spinning-drop method may be solved defining the relation between the radius of the sphere to the radius in the cylinder.
