Theoretical Model and Phase Behavior for Binary Surfactant Mixtures I ~

A new model for micellization beha..-ior of binary surfactant mixtures in solution is presented. A packing parameter, P* , has been introduced to describe the nonrandom mixing in mixed micelles. The significant feature of this model is that it considers asymmetric behavior ofmicellization in binary surfactant mixtures and predict5 the changes in the structures of mixed micelles with concentrati...

Phase Behavior and Structure of Binary Hard-Sphere Mixtures

By integrating out the degrees of freedom of the small spheres in a binary mixture of large and small hard spheres, we derive an explicit effective Hamiltonian for the large spheres. Using the two-body (depletion potential) contribution to this effective Hamiltonian in simulations, we find stable fluid-solid and both metastable fluid-fluid and solid-solid coexistence in a mixture with size rati...

Phase Segregation for Binary Mixtures of Bose-Einstein Condensates

We study the strong segregation limit for mixtures of Bose-Einstein condensates modelled by a Gross-Pitaievskii functional. Our first main result is that in presence of a trapping potential, for different intracomponent strengths, the Thomas-Fermi limit is sufficient to determine the shape of the minimizers. Our second main result is that for asymptotically equal intracomponent strengths, one n...

Molecular modeling of phase behavior and microstructure of acetone-chloroform-methanol binary mixtures.

Force fields based on a Lennard-Jones (LJ) 12-6 plus point charge functional form are developed for acetone and chloroform specifically to reproduce the minimum pressure azeotropy found experimentally in this system. Point charges are determined from a CHELPG population analysis performed on an acetone-chloroform dimer. The required electrostatic surface for this dimer is determined from ab ini...
