The dynamic breakup of emulsion droplets was demonstrated in double-layered microfluidic devices equipped with designed pneumatic actuators. Uniform emulsion droplets, produced by shearing at a T-junction, were broken into smaller droplets when they passed downstream through constrictions formed by a pneumatically actuated valve in the upper control layer. The valve-assisted droplet breakup was...

The present study was carried out to compare the inhibitory effect of alginate coatings containing Zataria Multiflora Boiss essential oil (ZMEO) in two forms of coarse emulsion and Nano-emulsion on the growth of inoculated Escherichia coli O157:H7in beef fillet during 16 days of refrigeration (4 C °). Accordingly, alginate solutions (3%) with different co...

Purpose: The quasi-emulsion solvent diffusion (QESD) has evolved into an effective technique to manufacture agglomerates of API crystals. Although, the proposed technique showed benefits, such as cost effectiveness, that is considerably sensitive to the choice of a stabilizer, which agonizes from a absence of systemic understanding in this field. In the present study, the combination of differe...

Setting of this paper is Bishop's constructive mathematics. For a relation σ on a set with apartness is called quasi-antiorder if it is consistent and cotransitive. The quasi-antiorder σ is complete if holds . 0 1 / = σ σ − ∩ In this paper the following assertion ‘A quasi-antiorder is the intersection of a collection of quasi-antiorders.’ is given.

the effect of addition of qodumeh shahri (lepidium perfoliatum) seed gum on the emulsion properties were investigated in this study. l. perfoliatum seed gum with 0-0.6% (w/w) concentration was used together with 2% (w/w) wpc to emulsify 20% (w/w) corn oil. the emulsion was analyzed for emulsion stability, particle size, specific surface area, particle size distribution and rheological propertie...

Emulsion of waxy crude oil is one of the common states in the subsea pipeline. At low temperatures in offshore environment, waxy crude oils with water could form the crude oil emulsion gel of oil-in-water emulsion. Thus, the waxy crude oil emulsion viscoelastic behavior for deep sea transportation and restarting pipeline safety is particularly important. By means of MASIII HAAKE rheometer which...

Extraction of nickel and its co-extraction with copper from ammoniacal media into emulsion liquid membrane systems (ELMs) was investigated using LIX 84I as the carrier. Measurement of the solute stripped in the internal phase of emulsion opened a new dimension in the study of the ELM extraction processes. The effect of operating parameters such as feed pH, initial feed concentration, and treat ...

Spherical crystallization of drugs is the process of obtaining larger particles by agglomeration during crystallization. The most common techniques used to obtain such particles are spherical agglomeration and quasi-emulsion solvent diffusion. Ammonia diffusion systems and crystallo-co-agglomeration are extensions of these techniques. By controlling process parameters during crystallization, su...

The purpose is to prepare 2% w/v emulsions of dodecafluoropentane, perfluorodecalin, and perfluoroctylbromide and compare them for their ability to absorb oxygen. The oxygen uptake capability and volume expansion of each emulsion and the blank vehicle were evaluated in water at 21 degrees C and 37 degrees C. The average particle size of the dodecafluoropentane emulsion is < 400 nm stored at roo...

Aim of the present study was to characterize the process of atomization and drying of layer-by-layer emulsions containing lecithin (single layer emulsion) and lecithin/chitosan (multilayer emulsion) and the oxidative stability of the spray-dried emulsions during storage. For this purpose, the analysis of the emulsion spray droplet size during atomization by two different atomization devices, i....
