Concentration phase diagram ofBaxSr1−xTiO3solid solutions

Phase Diagram of Colloidal Solutions.

The phase diagram of globular colloids is studied using a combined analytic and computational representation of the relevant chemical potentials. It is shown how the relative positions of the phase boundaries are related to the range of interaction and the number of contacts made per particle in the solid phase. The theory presented successfully describes the features of the phase diagrams obse...

Phase diagram of diblock polyampholyte solutions

We discuss in this paper the phase diagram of a diblock polyampholyte solution in the limit of high ionic strength as a function of concentration and charge asymmetry. This system is shown to be very similar to solutions of so-called charged-neutral diblock copolymers: at zero charge asymmetry the solution phase separates into a polyelectrolyte complex and almost pure solvent. Above a charge as...

Phase diagram of a model of nanoparticles in electrolyte solutions.

We obtain accurate fluid-fluid coexistence curves for a recent simple model of interacting nanoparticles that includes the effects of ion-dispersion forces. It has been proposed that these ion-dispersion forces provide at least a partial explanation for the Hofmeister effect [M. Bostrom et al. Phys. Rev. Lett. 87, 168103 (2001)]. We study a model of aluminum oxide nanoparticle [Deniz et al., Co...

Ferroelectric/Antiferroelectric Phase Coexistence in the Intermediate Concentration Regions of the BAxBP1−x Phase Diagram

The temperature (T)-concentration (x)-pressure (p) phase diagram of BAxBP1−x is characterized by the appearance of a variety of coexistence regions in the intermediate concentration region [1–4]. The nature of the different mixed phases, transitions and relaxations of the phase diagram, that reveal themselves in the measurements of the dielectric function [1, 2] is still unclear and difficult t...
