Controlled metal transfer in gas metal arc welding (GMAW) implies controllable weld quality. To understand, analyse and control the metal transfer process, the droplet should be monitored and tracked. To process the metal transfer images in double-electrode GMAW (DE-GMAW), a novel modification of GMAW, a brightness-based algorithm is proposed to locate the droplet and compute the droplet size a...

Self-Nanoemulsifying Drug Delivery Systems (SNEDDSs) were developed using well-defined excipients with the objective of mimicking digested SNEDDSs without the use of enzymes and in vitro lipolysis models and thereby enabling studies of the morphology and size of nanoemulsions as well as digested nanoemulsions by Cryo-TEM imaging and Dynamic Light Scattering. Four SNEDDSs (I-IV) were developed. ...

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...

In this paper, we got femtoliter volume droplet by splitting of nanoliter droplet at a T-junction channel, and the volume of the daughter droplet was not limited by the channel size. We use this droplet splitting system to entrap several fluorescent nanospheres, which show great potential to manipulate and observe single nanoparticles independently. The influences of fluid flow rate, channel ge...

Background: The dispersed phase volume fraction plays key role in oil-in-water emulsion stability by different mechanisms like partial flocculation, depletion flocculation and bridging flocculation. Since the mentioned mechanism is affected by emulsifier concentration presented in system, the major aim of this study was to investigate the effect of dispersed phase volume fraction on physical st...

Using the dynamic van der Waals theory [Phys. Rev. E 75, 036304 (2007)], we numerically investigate the hydrodynamics of Leidenfrost droplets under gravity in two dimensions. Some recent theoretical predictions and experimental observations are confirmed in our simulations. A Leidenfrost droplet larger than a critical size is shown to be unstable and break up into smaller droplets due to the Ra...

Objective(s): Nanoemulsions are a kind of emulsions that can be transparent, translucent (size range 50-200 nm) or “milky” (up to 500 nm). Nanoemulsions are adequatly effective for transfer of active component through skin which facilitate the entrance of the active component . The transparent nature of the system and lack of the thickener and fluidity are among advantages of nanoemulsion. Mate...

various compounds have been used for microencapsulating of fish oilso far, but in thiswork for the first time, inulin and casein which are both known for their functional properties, were used as the coating materialof fish oil.this study aimed to investigate the properties of nano-emulsions (droplet size measurements and ph) based on changes in the concentration and type of wall and their effe...
