چکیده

Non-aqueous Pickering emulsions of 16-240 μm diameter have been prepared using diblock copolymer worms with ethylene glycol as the droplet phase and an n-alkane as the continuous phase. Initial studies using n-dodecane resulted in stable emulsions that were significantly less turbid than conventional water-in-oil emulsions. This is attributed to the rather similar refractive indices of the latter two phases. By utilizing n-tetradecane as an alternative oil that almost precisely matches the refractive index of ethylene glycol, almost isorefractive ethylene glycol-in-n-tetradecane Pickering emulsions can be prepared. The droplet diameter and transparency of such emulsions can be systematically varied by adjusting the worm copolymer concentration.

We report the preparation of highly transparent oil-in-water Pickering emulsions using contrast-matched organic nanoparticles. This is achieved via addition of judicious amounts of either sucrose or glycerol to an aqueous dispersion of poly(glycerol monomethacrylate)56-poly(2,2,2-trifluoroethyl methacrylate)500 [PGMA-PTFEMA] diblock copolymer nanoparticles prior to high shear homogenization wit...

DNAPL Behavior in Fractured Rock – Transport Facilitated by Pickering Emulsions

Laboratory experiments demonstrate that finely divided solid materials (bentonite, iron oxide, magnesium oxide and manganese oxide) can form stable o/w emulsions for NAPLs such as PCBs, TCE, and diesel fuel. These emulsions, referred to as Pickering emulsions, are stabilized by finely divided solid materials that coat the NAPL-water interface; they do not require the presence of a surfactant to...

Crude Oil Interfacial Tension Reduction and Reservoir Wettability Alteration with Graphite or Activated Carbon/Silica Nanohybrid Pickering Emulsions

In this research, two carbon structures silica nanohybrids Pickering emulsions were prepared. Graphite and activated carbon were carbon allotropes with different morphologies of laminar and spherical, respectively. The effect of carbon morphology investigated on the related silica nanohybrids Pickeringemulsions for C-EOR. Therefore, nanohybrids were prepared with graphite and activated carbon t...

The Use of Pickering Emulsion for Mitigating Dye Leakage in Droplet Microfluidics

This work describes a strategy to mitigate the undesirable transport of small molecules among aqueous droplets immersed in fluorinated oil by replacing surfactant molecules with nanoparticles as emulsion stabilizers (Pickering emulsions). Amphiphilic silica particles were synthesized and redispersed in fluorinated solvents, and monodispersed picoliter aqueous drops were generated from flow-focu...

Lignin-based Pickering HIPEs for macroporous foams and their enhanced adsorption of copper(II) ions.

Interconnected macroporous foams were synthesized by templating oil-in-water Pickering high internal phase emulsions solely stabilized by lignin particles. They exhibited excellent adsorption capacity for copper(II) ions in aqueous solutions.
