the purpose of this study is to produce an oil-in-water nano-emulsion by ultrasonication. casein combined with inulin used as continuous phase, while dispersed phase consisted of fish oil. the size of the nano-emulsion and the ph of nano-emulsion were characterized. ultrasound has been used for preparing emulsion by 24 khz intensity for 120 seconds. prepared nano-emulsion was investigated by pa...

We experimentally study rearranging regions in slow athermal flow by observing the flow of a concentrated oil-in-water emulsion in a thin chamber with a constricting hopper shape. The gap of the chamber is smaller than the droplet diameters, so that the droplets are compressed into quasi-two-dimensional pancakes. We focus on localized rearrangements known as "T1 events" where four droplets exch...

Colloidal clay in water suspensions are known to exhibit a multitude of bulk phases depending on initial colloidal concentration and ionic strength, and examples of this include repulsive Wigner colloidal glasses at low ionic strength and attractive gels at higher ionic strength due to screened electrostatic forces by the electrolyte. From confocal Raman microscopy combined with elasticity meas...

felodipine is a second generation calcium channel blocker widely used as antihypertensive and antianginal drug which belongs to bcs class ii category. hence, its low water solubility limits the pharmacological effect. the aim of this study was to improve the dissolution rate of felodipine using spherical agglomeration technique with acetone, water and dichloromethane as good solvent, poor solve...

there are numerous problems for using essential oil due to its low solubility in water, high vapor pressure and chemical and physical instability. use of nano-emulsions is a good idea for decreasing side effect of the essential oils and enhance their efficiency as well as delivery to hot spot. in addition, nano-emulsion system make smaller size particles and increase stability and shelf-life of...

the use of panoramic radiography, due to its numerous advantages, is increasing. radiographic films used in this technique are of double emulsion (de) type which are used with intensifying screens. single emulsion (se) films can also be used. the purpose of this study was to determine the exposure parameters to achieve an appropriate optical density in these two types of films, and to estimate ...

The effect of silicone nano-emulsion softener against silicone conventional emulsion softener on the physical properties of cotton fabric has been studied. It is observed that the nano-emulsion softener improves the feel, softness and crease recovery to a higher extent compared to the conventional emulsion softener. However, the nano form of emulsion causes higher loss in strength with increase...

The purpose of this study was to produce oil in water Nano-emulsion by ultrasonication, and investigate the influence of Inulin and β-cyclodextrin on the prosperities of Nano-emulsion and morphology of spray dried microcapsules. The results showed that emulsion droplet size in samples containing β-cyclodextrin (8.28±0.11 nm) was less than Inulin samples (97.12±4.2 nm). Considering SEM photos, β...
