Core–shell droplets and microcapsules formed through liquid–liquid phase separation of a colloid–polymer mixture

Janus Supraparticles by Induced Phase Separation of Nanoparticles in Droplets

Adv. Mater. 2009, 21, 1949–1953 2009 WILEY-VCH Verlag G IO N Janus particles are non-centrosymmetric particles with two distinct sides. The two sides may differ in surface wettability or in optical, electrical, or magnetic properties. Depending upon the anisotropic properties, these particles can be used as emulsion stabilizers, analogous to surfactant molecules, optical probes for chemical, bi...

Polymerization-induced phase separation in a liquid-crystal-polymer mixture.

Phase separation dynamics in a two-dimensional magnetic mixture.

Based on classical density functional theory (DFT), we investigate the demixing phase transition of a two-dimensional, binary Heisenberg fluid mixture. The particles in the mixture are modeled as Gaussian soft spheres, where one component is characterized by an additional classical spin-spin interaction of Heisenberg type. Within the DFT we treat the particle interactions using a mean-field app...

A new process for making reservoir-type microcapsules using ink-jet technology and interfacial phase separation.

A new microencapsulation technique that utilizes interfacial mass transfer between two mutually soluble liquids has been developed. The technique is based on formation of a solid polymer film at the interface of a solution of a water-insoluble polymer and an aqueous solution, resulting from the mutual mass transfer of solvents (i.e., solvent exchange). Reservoir-type microcapsules were prepared...

Separation and Recovery of Platinum by Magnetic Coreshell Nanostructures Modified with N-(2-aminoethyl)-3- aminopropyltrimethoxysilane

In this paper, Fe3 O4 @SiO2 core/shell magnetic nanostructure has been synthesized and modified by N-(2-aminoethyl)-3-aminopropyltrimethoxysilane (AEAPTMS). Fe3 O4 @SiO2 was used as a novel adsorbent for separation of hexachloroplatinic acid. X-ray diffraction (XRD), scanning electron microscopy (SEM), and FT-IR technique were used to characterize morphologies and surface texturing of these ads...
