A stable water-in-oil-in-water (W1/O/W2) double emulsion containing in its inner aqueous phase a microbial consortium (60mgprotein L 1 double emulsion) known to degrade methyl tert-butyl ether (MTBE) was prepared. The primary emulsion (W1/O) had a volume disperse phase (f1) of 0.3 and was stabilized with 8% Span 80. The double emulsion had a volume disperse phase (f2) of 0.3 and was stabilized ...

We use dissipative particle dynamics (DPD) and molecular models to simulate interacting oil/water/surfactant interfaces. The system comprises sections of two emulsion droplets separated by a film. The film is in equilibrium with a continuous phase, in analogy with the surface force apparatus. This is achieved by combining DPD with a Monte Carlo scheme to simulate a muVT ensemble. The setup enab...

One small-scale double emulsion technique for incorporation of Naja- Naja oxiana venom into Poly (lactide-co-glycolide) (PLGA) microspheres were developed and optimized. The effects of high speed homogenization on the double emulsion stability, microsphere size, entrapment efficiency and In vitro release of venom were studied. A stable double emulsion was verified by homogenization method. Slow...

Recent experiments have shown that coalescence of an oil/water/nanoparticle Pickering emulsion contained in a vial induces a nanoparticle-film o climb up the walls of the vial. Here we show that this phenomenon is highly general and can be induced by a variety of particle types, particle izes ranging from a few nm to a few m, and different emulsion types. Many of the features of film growth des...

Insomnia is becoming increasingly prevalent in the world general population. Therapies used by patients include over-the-counter therapies, herbal and dietary supplements, and pharmacological or nonpharmacological treatments. Among these, zolpidem is a pharmacological treatment popularly used for insomnia. Zolpidem is well tolerated and especially efficacious for initiation of sleep, and theref...

Perfluorocarbon (PFC) double emulsions loaded with a water-soluble, therapeutic agent can be triggered by ultrasound in a process known as acoustic droplet vaporization. Elucidating the stability and biodistribution of these sonosensitive vehicles and encapsulated agents is critical in developing targeted drug delivery strategies using ultrasound. [(18) F]fluorodeoxyglucose (FDG) was encapsulat...

The intake of dietary salt through food now exceeds current nutritional recommendations and is thought to have negative effects on human health, such as the increasing prevalence of hypertension. This study was performed to investigate whether W1/O/W2 double emulsions can be used to enhance the saltiness of cheese without increasing the salt content (W1 is distilled water or 1% abalone hydrolys...

Coalescence is a critical phenomenon in separation and transport processes. An improved understanding of coalescence can enhance current models predicting emulsion stability separation. We here report combined experimental simulation study to investigate the thin film prior its rupture event. Optical tweezers measured influence ions surface-active agents on time forces acting between colliding ...

A number of processes are available: condensation-, interfacial-, suspensionand emulsion-polymerization. Suspension and emulsion polymerization are the preferred methods for the commercial production of polymer microsphere carrier particles and reference/standard particles for calibration of scientific instruments. In general, emulsion polymerization produces a smaller particle size and a narro...

Madecassoside (MA) is highly potent in treating skin disorders such as wounds and psoriasis. However, the topical wound healing effect of MA was hampered by its poor membrane permeability. In order to overcome this shortcoming, MA liposomes were designed and prepared by a double-emulsion method to enhance transdermal and wound healing effects. In this study, response surface methodology was ado...
