Macroporous solid foams with magnetic properties may have interesting applications as adsorbents for purification and decontamination processes. High pore volume can ensure a high degree of absorption, and magnetic properties can facilitate removal from environment. Organic macroporous polymeric foams, with high pore volume and high degree of interconnectivity, can be obtained by polymerizing i...

The effective capillary interaction potentials for small colloidal particles trapped at the surface of liquid droplets are calculated analytically. Pair potentials between capillary monopoles and dipoles, corresponding to particles floating on a droplet with a fixed center of mass and subjected to external forces and torques, respectively, exhibit a repulsion at large angular separations and an...

We prepare solid-stabilized emulsions using paramagnetic particles at an oil/water interface that can undergo macroscopic phase separation upon application of an external magnetic field. A critical field strength is found for which emulsion droplets begin to translate into the continuous-phase fluid. At higher fields, the emulsions destabilize, leading to a fully phase-separated system. This ef...

Pickering emulsions, emulsions stabilized by solid emulsifiers, offer many opportunities for application in catalysis. Recent advances emulsifier design, type of conversions catalyzed and developments reaction engineering are discussed.

Multifunctional amphiphilic hollow carbonaceous spheres assembled into Pickering emulsions exhibit reversible pH-dependent phase-transfer behavior and can efficiently catalyze water/oil biphasic reactions, facilitating the recycling of the catalysts and separation of the products.

Herein, we propose a facile protocol for the fabrication of biomedical microstructures with fine textures of hierarchical rippled and crumpled morphologies through double emulsions by the simple addition of interior Pickering nanoparticles.
