For a multiproduct microalgal biorefinery, most of the cell components should be extracted and fractionated. This work investigates fractionation lipids from other (pigments, proteins, carbohydrates) using polymers IL solutions in aqueous two-phase systems (ATPS). The poorly migrated to phases ATPS were recovered (97% total fatty acids) third phase (interphase) formed between top bottom phases....

Beverage emulsions are systems that are composed of two liquids including oil and water which are prepared by homogenizing oil phase in an acidic aqueous phase. They must be stable in both concentrated and diluted form for a period of 6-12 months upon standing at room temperature. Two immiscible phases contained systems are thermodynamically unsta-ble. In other words, they are vulnerable to bre...

Monolayers based on the composition of the cytoplasmic (CYT) or extracellular (EXT) sides of the myelin bilayer form coexisting immiscible liquid phases similar to the liquid-ordered/liquid-disordered phases in phospholipid/cholesterol monolayers. Increasing the temperature or surface pressure causes the two liquid phases to mix, although in significantly different fashion for the CYT and EXT m...

The distinctive features of limited solubility in liquid eutectic and monotectic metallic systems have been discovered. The monodispersed emulsion model has been elaborated for a description of the specific microheterogeneous structure of eutectic melts. It includes the transitional shells (TS) at the interface boundaries having the eutectic composition and the closest packing of atoms. By mean...

Two peptides known to interact with receptors embedded in cell membranes, angiotensin III (Ang III) and Leu-enkephalin (LeuEnk), were studied electrochemically at the interface formed between two immiscible electrolyte solutions modified by an adsorbed monolayer of dipalmitoylphosphatidylcholine (DPPC). The results indicate that cationic angiotensin III transfer can be facilitated by the interf...

In this paper, we investigate, on two levels of description, the isothermal coupling: ~i! between rheology and morphology in immiscible blends ~A/B! and ~ii! among rheology, morphology, and diffusion in mixtures consisting of an immiscible blend ~A/B! and one simple fluid, s. The interface separating the phases A and B is described, on the kinetic level by an area density distribution function ...

New AlxCo50?xCu50?xMnx (x = 2.5, 10, and 15 atomic %, at%) immiscible medium-entropy alloys (IMMEAs) were designed based on the cobalt-copper binary system. Aluminum, a strong B2 phase former, was added to enhance yield strength ultimate tensile strength, while manganese for additional solid solution strengthening. In this work, microstructural evolution mechanical properties of Al-Co-Cu-Mn sys...

Abstract To analyze the complex droplet transient deformation involving two immiscible phases, a practical multi-interfacial tension model has been introduced in SPH framework. The attraction, which operates on interface between different phases is explicitly defined as London dispersion force using Fowkes theoretical model, and interfacial can be calculated sum of attraction magnitudes corresp...

We investigate the acoustic and mechanical properties of a reservoir sandstone saturated by two immiscible hydrocarbon fluids, under different saturations and pressure conditions. The modeling of static and dynamic deformation processes in porous rocks saturated by immiscible fluids depends on many parameters such as, for instance, porosity, permeability, pore fluid, fluid saturation, fluid pre...

Mechanical alloying (MA) is a powder process that consists of repeated cold welding, fracturing, and rewelding particles in high-energy ball mill. This capable synthesizing different types non-equilibrium phases including supersaturated solid solutions, nanocrystalline materials, metallic glasses, high-entropy alloys, several others. MA'd materials have found many applications. The present arti...
