“…At 20 %w/w n-decane, an increasing in Brij 30 concentration decreased the PIT of the system and decreased the droplet size 58 . Similarly, Mei et al reported that the PIT of paraffin oil/water nanoemulsions stabilized by Tween 80/Span 80 decreased with an increase in surfactant-to-oil ratio 46 .…”

“…By successively addition of NaBH 4 , pH of the medium increased and a transition in the spontaneous radius of curvature of span-80 is observed. At this time system crosses a point of zero spontaneous curvature and minimal surface tension, promoting the formation of finely dispersed droplets 22 . At higher oil phase content (i.e.…”

Controllable synthesis of uniform spherical silver nanoparticles was investigated by carrying out a chemical reduction reaction in a micro emulsion, formed under high shear mixing of aqueous silver nitrate solution and 2-ethyl hexanol as organic phase. Sodium borohydride was used as reducing agent and sorbitan monooleate (span-80) as stabilizer. Further, a study has been performed to observe the effect of silver nitrate concentration, reducing agent concentration, amount of surfactant and organic phase on the size and shape of silver nanoparticles. Transmission electron microscopy (TEM) and dynamic light scattering (DLS) techniques were used for elucidating the shape, size and size distribution of the synthesized silver nanoparticles. Crystal structure of silver nanoparticles thus prepared has been studied by X-ray diffraction analysis (XRD). Uniform silver nanoparticles of average diameter 15-20 nm with high purity and well crystalline nature were obtained under optimized set of conditions. The results of synthesis of these nanoparticles in present study were excellent and may also be used at larger scale.

“…Increasing temperature will result in an increase in emulsion droplet size and polydispersity owing to coarsening by Ostwald ripening and/or coalescence. 35 Accordingly, an optimized continuous phase temperature of 25°C was achieved.…”
