Multiple interfaces in diffusional phase transitions in binary mesogen-nonmesogen mixtures undergoing metastable phase separations
(American Physical Society, 2012-07)
Theory and simulations of simultaneous chemical demixing and phase ordering are performed for a mixed order parameter system with an isotropic-isotropic (I-I) phase separation that is metastable with respect to an ...
Aqueous two-phase systems for protein separation: Phase separation and applications
Aqueous two-phase systems (ATPS) that are formed by mixing a polymer (usually polyethylene glycol, PEG) and a salt (e.g. phosphate, sulphate or citrate) or two polymers, and water can be effectively used for the separation ...
Thermoset-Thermoplastic Nanostructured Blends
Polymers are chemical compounds of high molecular weight (on the order 1000-10,000.000), named macromolecule. They are formed by the repetition of a basic unit called mere whose parameter . n is defined by the degree of ...
Self-assembly of nanoparticles employing polymerization-induced phase separation
Nanoparticles (NPs) may be homogeneously dispersed in the precursors of a polymer (reactive solvent) by an adequate selection of their stabilizing ligands. However, the dispersion can become metastable or unstable in the ...
An overview of the chromatographic properties and stability of C-18 titanized phases
(Wiley-v C H Verlag GmbhWeinheimAlemanha, 2006)
Morphology profiles obtained by reaction-induced phase separation in epoxy/polysulfone/poly(ether imide) systems
The reaction-induced phase separation in epoxy/aromatic diamine formulations simultaneously modified with two immiscible thermoplastics (TPs), poly(ether imide) (PEI) and polysulfone (PSF), has been studied. The epoxy ...
Phase separation in Ag–Ge–Se glasses
(Elsevier Science, 2007-05)
Field emission-scanning electron microscopy (FE-SEM) and electric force microscopy (EFM) measurements were carried out on bulk Agx(Ge0.25Se0.75)100−x glasses with x = 5 and 15 at.%. The presence of chemical contrasts and ...
Poly(ether imide) membranes obtained from solution in cosolvent mixtures
