Magnetic field directed self-assembly of gold Pickering emulsion for preparing patterned film.
… ordered arrays of the gold nanoparticle Pickering ferrofluid in polyvinyl alcohol (PVA) emulsion, in the form of a thin film on glass and silicon substrate. Previously-conducted MSCDS processes lacked the control over the dimensions of the prepared patterns. Here, the static magnetic …

Novel techniques for microencapsulation of probiotic bacteria
… of living cells, we used templates of Pickering emulsions stabilised with latex nanoparticles to fabricate colloidosomes loaded with viable probiotics. Depending on the method of transfer, we have shown that magnetic colloidosomes containing pH-sensitive polyelectrolyte loaded with …

Novel applications of surface-modified sporopollenin exine capsules
… has been investigated for the stabilization of Pickering emulsion by Binks et al. In this work, sporopollenin was aminated and their behaviour as emulsifiers has been studied. The amino groups on the surface of sporopollenin will change the hydrophilicity of the particles and affect their …

Wettability of solid particles in relation to particle-stabilised foams and emulsions
… individually or combined, as stabilisers of emulsions and foams. While the properties of surfactants and particles under a range of conditions and concentrations are relatively well known, there are some areas that require further investigation. The wettability of colloidal particles is one …

Soft Compartmentalized Polymer Colloids: Janus Particles, Multicompartment Structures, Inorganic-Organic Hybrids and Applications
… of both academic and industrial relevance. In Pickering emulsion polymerization, extremely well-defined latexes with long-term stability could be prepared in a very facile fashion. A control of the particle size by changing the concentration of Janus particles could easily be achieved. …

Microcapsule-based self-protecting coatings
… to form a viable system. Microcapsules formed a Pickering emulsion of carbon black particles at the interior shell wall. PhotoDSC characterization shows as much as 65% UV blockage at 365 nm. Fluorescence signature (405 nm excitation and 410-600 nm emission) with an encapsulated fluorescent dye …

Janus Particles at Interfaces
… synthesis is based on a modified version of the Pickering emulsion technique in combination with surface-initiated atom transfer radical polymerization (ATRP) in a “grafting from” approach. First, 30 nm silica nanoparticles are immobilized at the interface of sub-micrometer sized droplets of …

Microfluidic assembly of zein microcapsules
… were used as building blocks to stabilize emulsions. By tuning the wettability of the zein nanoparticles with sodium caseinate, the emulsion stability was further improved. An optimal zein: caseinate ratio of 10:3 increased the interfacial coverage of oil droplets. This emulsifying ability …
