TLDR
In this article, the surface tension and density of toluene + heptane and N,N-dimethylformamide+toluene at atmospheric pressure were measured over a temperature range.Abstract:
The pendant drop method, combined with efficient temperature control of the measuring cell, allows high precision in surface tension measurements. The surface tensions of heptane, toluene, N,N-dimethylformamide, cyclohexane, N-methyl-2-pyrrolidone, and propanone were measured as a function of temperature using the pendant drop method. The results were compared with literature data. The surface tension and density of toluene + heptane and N,N-dimethylformamide + toluene at atmospheric pressure were measured over a temperature range. Gibbs excess surface concentrations are derived from the experimental surface tensions, and the influence of activity coefficients is discussed.read more

Incorporation of phenoxy groups in self-assembled monolayers of trichlorosilane derivatives. Effects on film thickness, wettability, and molecular orientation
TL;DR: Model studies of monolayer-forming trichlorosilane derivatives containing aromatic functional groups which incorporate a phenoxy moiety in various positions of a long alkyl chain showed that the phenoxy group can be introduced into such monolayers with no loss of oleophobicity, as compared with octadecyltrichloro-silanes (OTS), and with spectral features which indicate a high level ofmonolayer order and close packing.
