Understanding the phenomenon of droplet coalescence in nanoparticle suspensions is extremely important for the preparation of Pickering emulsions. A microfluidic platform, which can provide compulsive droplet collisions, was developed to imitate the droplet coalescence process in the early stages of emulsification. Microscope videos showed the variations in the droplet coalescence percentage, d...

Abstract This review discusses the application of oleogel technology in emulsified systems. In these systems mimetic fats, water-in-oil or oil-in-water emulsions can be obtained, but, here, we cover with an oil continuous phase detail. Depending on percentage water added to oleogels, different textures and rheological properties developed. These are affected by characteristics concentration com...

Emulsions stabilized by solid particles, called Pickering emulsions, offer promising applications in drug delivery, cosmetics, food science and the manufacturing of porous materials. This potential stems from their high stability against coalescence and 'surfactant-free' nature. Generally, Pickering emulsions require that the solid particles are wetted by both phases and as a result, the adsorp...

Submitted for the DFD09 Meeting of The American Physical Society Conditions for Destabilizing Pickering emulsions using external electric fields KYUHO HWANG, PUSHPENDRA SINGH, NADINE AUBRY — Fine particles are readily adsorbed at fluid-fluid interfaces, and can be used as stabilizers in emulsion technology by preventing adjacent drops from coalescing with each other. We investigate a new techni...

Within the "compartmentalised smart factory" approach of the ONE-FLOW project the implementation of different catalysts in "compartments" provided by Pickering emulsions and their application in continuous flow is targeted. We present here the development of heterogeneous Pd catalysts that are ready to be used in combination with biocatalysts for catalytic cascade synthesis of active pharmaceut...

The rational formulation of Pickering double emulsions is described using a judicious combination of hydrophilic and hydrophobic block copolymer worms as highly anisotropic emulsifiers. More specifically, RAFT dispersion polymerization was utilized to prepare poly(lauryl methacrylate)-poly(benzyl methacrylate) worms at 20% w/w solids in n-dodecane and poly(glycerol monomethacrylate)-poly(2-hydr...

Pickering emulsions stabilized by polysaccharide particles have attracted extensive research interest in the food, biopharmaceutical and cosmetic industries due to their ability edibility, protect bioactive substances, control release of substances. This paper reviewed progress using natural polysaccharides, modified polysaccharides physical or chemical method complexes as form stabilize emulsi...

Doubly curved nanofiber-reinforced optically transparent composites with low thermal expansion of 15 ppm/k are prepared by hot pressing vacuum-filtered Pickering emulsions of hydrophobic acrylic resin monomer, hydrophilic chitin nanofibers and water. The coalescence of acrylic monomer droplets in the emulsion is prevented by the chitin nanofibers network. This transparent composite has 3D shape...
