Density functional theory for colloidal rod-sphere mixtures M. Schmidt, Phys. Rev. E 63, 050201(R) (2001). Locate in [bare] [illustrated] list. Get [full paper] as pdf. Extract. We present a density functional theory for a model colloidal mixture of hard spheres and infinitely thin hard rods. For isotropic bulk fluid mixtures, the free energy, and hence the demixing phase diagram, are identical to that obtained from free volume theory. Results for the bulk partial pair correlation functions are in good agreement with simulations. [more]  Read the [full paper] as pdf. |
Rod-sphere mixtures
The DFT of [19] was extended to treat rod-rod interactions [30] [49], and used for free fluid interfaces [30] and wetting at a hard wall [40]. Simulations [42] confirmed unusual interfacial rod ordering. See [25] for the demixing phase behavior of the system upon adding polymers.[more]
