Temperature dependence of the surface tension for binary mixtures ofn-butanenitrile +n-alkanes

Abstract

The difl'crential capillary-rise method was used to determine the orthoharic surface [cnsion of binary liquid mixtures of n-butancnitrilc mixed with n-pent,me. n-hcxanc, and n-hcptanc, throughout the composilion range, at 293.15. 3(13.15. 313.15. 323.15, 333.15. and 343.15 K. l:urthcrmorc, the system with n-hcxanc was also studied at 263.15 K, i.e.. 19 K above its upper critical sc, lutic, n tcmperaturc, over the v,,holc cotnposilion range. For each binary s.vSlelll lh,2 surface tension changes regularly with both Icmpcralur¢ and composition between tile vdltl,.2s of the pure conlpont:nls. The results arc discusst:d ill lernls of deviations from surface idcality and related to the large positive deviations observed for bulk properties of the samc systems.

Atomistic and Coarse-Grained Modeling of the Adsorption of Graphene Nanoflakes at the Oil–Water Interface

“…No longrange corrections were used for pressure or energy. This model yields γ o = 11.2 ± 0.4 mJ/m 2 , which underestimates the experimental value (15.43 mJ/m 2 at 323 K 53 ). Atomistic water was modeled with the SPC/E 54 model.…”
