Critical point of electrolyte mixtures.
The critical behavior of electrolyte mixtures was studied using grand canonical Monte Carlo simulations. Mixtures consist of large multivalent macroions and small monovalent co- and counterions. The system can be viewed as a binary mixture of macroions (with their counterions) and salt (co- and counterion pair). The primitive model description was used, in which the ions are point charges with ...
متن کاملAn apparent critical point in binary mixtures of nitrotoluene with alkanes: Experimental and simulation study
We report an experimental and simulation study of binary mixtures of oand m-nitrotoluene with decane and hexadecane. Mixtures of o-nitrotoluene with alkanes form a classical critical mixtures, but m-nitrotoluene / n – alkane mixtures show an apparent critical point, which lies in a metastable, experimentally inaccessible state, below the melting point, affecting physical and chemical properties...
متن کامل*H and H NMR Studies of Mixtures 2,6-Lutidine/Water Near the Lower Critical Solution Point
Deuteron spin-lattice relaxation time (TJ measurements of binary mixtures 2,6-lut idine/D20 have been done near the lower critical solution point (Tc L), e = (T — Tg L)/Tc 10~. Singularities are observed at Tc L . The changes in the slope of Ti (H) = / ( T ) can be interpreted as due to the effect of concentration changes on Ty and simultaneously strong overlaping of H N M R signals from coexis...
متن کاملSurface Adsorption and Orientation near the Critical Point of Binary Liquid Mixtures
The noncritical liquid/vapor surface is completely saturated with the component of smaller surface tension for sufficiently large surface tension difference between the two components of a critical liquid binary mixture. This complete (or strong) adsorption is described by a universal scaling function of the volume fraction order parameter. We have determined the universal function P; the model...
متن کاملCritical point calculation for binary mixtures of symmetric non-additive hard disks
We have calculated the values of critical packing fractions for the mixtures of symmetric non-additive hard disks. An interesting feature of the model is the fact that the internal energy is zero and the phase transitions are entropically driven. A cluster algorithm for Monte Carlo simulations in a semigrand ensemble was used. The finite size scaling analysis was employed to compute the critica...
