Mineralized Bionanoparticle Pickering Emulsions
… of mineralized, bionanoparticle-stabilized Pickering emulsions were investigated in this work. Proteins (HSA, BSA, fetuin-A), protein cages (ferritin) and plant viruses (CPMV, TYMV, TMV) were employed to produce functional nanopatterned surfaces and interfaces by means of Pickering emulsions …

Equilibrium Conditions of Hydrate-Forming Pickering Emulsions
… data of (cyclopentane hydrate + water 60:40) emulsions, in the concentration range from 0.1 to 2% of Span 80, is determined at atmospheric pressure (101.325 kPa). Requirements for thermodynamic validity of the equilibrium temperatures measured by this technique are investigated and discussed …

The Design, Preparation and Characterisation of Light-Responsive Pickering Emulsions
Light-responsive particle-stabilised (Pickering) emulsions can, in principle, be selectively emulsified or demulsified on-demand through the remote application of light. However, despite their wide-ranging potential in applications such as drug delivery and biphasic catalysis, their rational design …

Microgels at oil-water interfaces
Particle-stabilized emulsions, so called Pickering Emulsions, are known for more than a century. In such emulsions particles, mostly inorganic particles in the nm to µm range, adsorb to oil/water interfaces and stabilize emulsions by coulomb and sterical repulsion. Pickering emulsions are usually …

Unique Emulsions based on recombinant Hydrophobins
… in the formation of gel-like oil in water emulsions. Interestingly, without the occurrence of typical emulsion instability processes like creaming or coalescence, these emulsions showed significant aging effects. We conclude them to be the consequence of the time-dependent formation and …

Evaporation rates from emulsions stabilised by surfactants and nanoparticles
… is concerned with the evaporation rates of emulsions stabilised by either surfactant molecules or nm-size solid particles. Understanding of the mechanisms of the evaporation process plus the control of the rate limiting step of each mechanism involved in such processes is important for a …

Self assembled transmembrane protein polymer conjugates for the generation of nano thin membranes and micro compartments
… self assemble onto polar apolar interfaces. The emulsions stabilized by particles or conjugates are referred to as Pickering emulsions. Crosslinking conjugates with a UV crosslinkable co monomer afforded nano thin micro compartments. Interfacial self assembly at the air water interface and …

Cellulose Nanocrystals as 'Green' Emulsifiers Stabilized Crude Oil in Water Emulsions
… the ability of CNC to stabilize crude o/w Pickering emulsions. The effects of concentration of CNC, ionic strength of the aqueous phase, volume fraction of crude oil to water, and the presence of divalent ions on the stability of crude o/w emulsions were examined. Emulsions stabilized with …

Hydrophobic-Hydrophilic Separation Process for the Recovery of Ultrafine Particles
… involved in converting oil-in-water (o/w) Pickering emulsions to water-in-oil (w/o) Pickering emulsions. Many of the studies has, therefore, been focused on the studies of phase inversion mechanisms. The results showed that phase inversion requires that i) the oil contact angles (θo) of the …

Carbon Nanotubes for the Stabilization of Lipid Nanostructured Particles
… stabilisers; resultant are the oil-in-water emulsions, which are common in many food and consumer products. Surfactant based stabilisers have been very popular; however, for particular applications the surfactant molecules are not completely beneficial. In this case, the solid materials are …

Halloysite for smart nano-structured materials in sustainable applications
… designed a new protocol for the preparation of Pickering emulsions based on halloysite and paraffin wax. Optical and Scanning Electron Microscopy allowed to study the morphological features of the prepared particles and to find a dependence between their dimensions and the clay content. DSC …

DEVELOPMENT OF CHITIN NANOCRYSTALS AND THEIR APPLICATIONS IN FOOD AND AGRICULTURAL AREAS
… and O-ChNCs were investigated as stabilizers in Pickering emulsions. Both were able to significantly enhance the stability of oil-in-water (O/W) emulsions, particularly when pH > 9. O-ChNCs further demonstrated encapsulation efficiencies of up to 80% for bioactive compounds like quercetin, …

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 …
