In this study, a membrane-integrated glass capillary device for preparing small-sized water-in-oil-in-water (W/O/W) emulsion droplets is demonstrated. The concept of integrating microfluidics to prepare precise structure-controlled double emulsion droplets with the membrane emulsification technique provides a simple method for preparing small-sized and structure-controlled double emulsion dropl...

background: conventional tomography used for evaluation of the small areas of the jaws provides acceptable information. it has some advantages of availability, less radiation dose and costin comparison to computed tomography (ct) and cone beam ct. double emulsion film usuallyused for taking tomograms requires less exposure than single emulsion film; on the other hand,the latter provides more sh...

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 ...

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...
