Pickering emulsions for skin decontamination
Toxicology in Vitro, 2016This study aimed at developing innovative systems for skin decontamination. Pickering emulsions, i.e. solid-stabilized emulsions, containing silica (S-PE) or Fuller's earth (FE-PE) were formulated. Their efficiency for skin decontamination was evaluated, in vitro, 45min after an exposure to VX, one of the most highly toxic chemical warfare agents ...

The stepwise organization of nanoparticles into a Pickering emulsion
Soft Matter, 2021Homogeneous composite nanoparticles undergo stepwise organization from individual nanoparticles that capture oil to stable aggregates to the formation of a Pickering emulsion as oil is continuously fed into the aqueous dispersion.

Optical Properties of Pickering Emulsions and Foams
Langmuir, 2022A significant number of studies have been conducted on particle adhesion phenomena as pertaining to the oil-water interface of droplets and the air-liquid interface of bubbles, known as Pickering emulsions and Pickering foams, respectively. However, few of the literature reports have discussed the optical properties of these materials.

Aggregation in Pickering emulsions
Colloid & Polymer Science, 1999For the first time, the particle distribution and aggregation in Pickering emulsions were made visible by transmission X-ray microscopy. Oil/water emulsions were stabilized by heterocoagulates of a clay mineral and magnesium aluminum hydroxide. Stability is optimum when the particles surround the oil droplets and also assemble to form a network ...

Pickering Janus Emulsions Stabilized with Gold Nanoparticles
Langmuir, 2021We report a modified approach to the batch scale preparation of completely engulfed core-shell emulsions or partially engulfed Janus emulsions with colorful optical properties, containing water, olive oil, and silicone oil. The in situ reduction of gold chloride, forming gold nanoparticles (AuNPs) at the olive oil interface in the absence or presence ...

Pickering emulsions stabilized by charged nanoparticles
Soft Matter, 2016The stabilization of o/w Pickering emulsions in cases of weak adsorption of solid particles at the surface of oil droplets is addressed. Though the adsorption is usually very strong and irreversible when partial wetting conditions are fulfilled, electrostatic repulsions between charged solid particles act against the adsorption.

Multiple Pickering Emulsions Stabilized by Microbowls
Langmuir, 2011Some researchers have focused on the adsorption of solid particles at fluid-fluid interfaces and prepared emulsions and foams called "Pickering emulsions/foams". However, while several reports exist on simple spherical emulsions, few reports are available on the formation of more complex structures.

Pickering emulsions in foods - opportunities and limitations
Critical Reviews in Food Science and Nutrition, 2017In order to critically discuss the potential of Pickering-type emulsions in food applications this review provides the theoretical background of the stabilizing mechanisms, the resulting requirements for particles to stabilize these systems and the limitations resulting from these fundamental considerations.

Pickering/Non‐Pickering Emulsions of Nanostructured Sulfonated Lignin Derivatives
ChemSusChem, 2020AbstractSulfoethylated lignin (SEKL) polymeric surfactant and sulfoethylated lignin nanoparticles (N‐SEKL) with a size of 750±50 nm are produced by using a facile green process involving a solvent‐free reaction and acidification‐based fractionation. SEKL forms a liquid‐like conventional emulsion with low viscosity that has temporary stability (5 h) at ...
