Using a first-principles cluster expansion, we shed light on the solid-state phase diagram and structure of the recently discovered high-performance Pb-Ag-Sb-Te thermoelectrics. The calculated bulk thermodynamics favors the formation of coherent precipitates of ordered Ag(m)Sb(n)Te(m+n) phases immiscible with rocksalt PbTe, such as AgSbTe2. The solubility is high for Pb in AgSbTe2 and low for (...

Recently achieved two-component dipolar Bose-Einstein condensates open exciting possibilities for the study of mixtures ultra-dilute quantum liquids. While non-dipolar self-bound are necessarily miscible with an approximately fixed ratio between two densities, density case is free. As a result, present qualitatively novel and much richer physics, characterized by three possible ground-state pha...

We study a U (1) × U (1) system with two species of loops with mutual π statistics in (2 + 1) dimensions. We are able to reformulate the model in a way that can be studied by Monte Carlo and we determine the phase diagram. In addition to a phase with no loops, we find two phases with only one species of loop proliferated. The model has a self-dual line, a segment of which separates these two ph...

In this present study, volume of fluid method in OpenFOAM open source CFD package will be extended to consider phase change phenomena with modified model due to condensation and boiling processes. This model is suitable for the case in which both unsaturated phase and saturated phase are present and for beginning boiling and condensation process needn't initial interface. Both phases (liquid-va...

The primary objective of this study was to pragmatically implement an extraction process using slug flow, wherein two immiscible phases, aqueous and oil, are alternatively channeled through a conduit encourage mass exchange across the interface. To facilitate this, we introduced empirically validated in-line technique precisely quantify length potential concentration aforementioned phases. its ...

In the present work, we propose a consistent and conservative model for multiphase multicomponent incompressible flows, where there can be arbitrary numbers of phases components. Each phase has background fluid called pure phase, each pair is immiscible, components are dissolvable in some specific phases. The developed based on Phase-Field including contact angle boundary condition, diffuse dom...

The objective of this study was to examine the pore-scale distribution and morphology of organic immiscible liquid in natural porous media containing three immiscible fluids. High-resolution, threedimensional images of an organic liquid (tetrachloroethene) in both three-phase (water–air–organic liquid) and two-phase (water–organic liquid) systems were obtained using synchrotron X-ray microtomog...

Many microorganisms are able to produce a wide range of amphipathic compounds, with both hydrophilic and hydrophobic moieties present within the same molecule which allow them to exhibit surface activities at interfaces and are generally called biosurfactants or bioemulsifiers. These surface-active compounds (SAC) are mainly classified according to their mode of action, molecular weight and gen...

We study the ow of two immiscible uids of diierent density and mobility in a porous medium. If the heavier phase lies above the lighter one, the interface is observed to be unstable. The two phases start to mix on a mesoscopic scale and the mixing zone grows in time | an example of evolution of microstructure. A simple set of assumptions on the physics of this two{phase ow in a porous medium le...
