The microscopic interactions between oil droplets during the coalescence process have an important impact on stability of emulsion. In this paper, a model that can present phenomenon was established. Experiments were carried out to evaluate Combined with molecular dynamics simulation technology, behaviors emulsified in fluids produced by wells studied. Factors affecting analyzed. results show f...

Directed evolution relies on iterative cycles of randomization and selection. The outcome of an artificial evolution experiment is crucially dependent on (i) the numbers of variants that can be screened and (ii) the quality of the assessment of each clone that forms the basis for selection. Compartmentalization of screening assays in water-in-oil emulsion droplets provides an opportunity to scr...

One of general free boundary problems concerning the electrohydrodynamic effects on a concentric double emulsion drop is studied theoretically for the three constituent phases of leaky dielectric fluids. In order to proceed the problem analytically, the domain perturbation procedure is utilized in the small deformation limit. The patterns of electric-field-driven flow are successfully character...

During the crude oil production, water-in-oil stable emulsions may be created. Water which is naturally present in reservoirs mixes with to form very due high shear rates and zones of turbulence encountered at wellhead pipe production. The formation these generally caused by presence resins, asphaltenes, wax naphtenic acid play role "natural emulsifiers. aim this study was focus on some importa...

Abstract   An empirical investigation was carried out to study convective heat transfer of nanofluid flow inside an inclined copper tube under uniform heat flux condition. Required data are acquired for laminar and hydrodynamically fully developed flow inside round tube. The stable CuO-base oil nanofluid with different nanoparticle weight fractions of 0.5%, 1% and 2% was produced by means of ul...

“Pitanga” leaf hydroethanolic extract (PLHE) presents high antioxidant and antimicrobial activities. The encapsulation of this in W/O/W double emulsions could protect its bioactive properties. objective research was to encapsulate PLHE the inner W phase a emulsion analyze emulsifiers concentrations ratios effects on droplet size physical stability. Moreover, rheological behavior, activities the...

Reformulation approaches in the meat industry are required to promote nutritional improvement, health functionality, and reduce environmental impact. A relevant approach among these is amount of products. Reduced-meat products should maintain or improve sensory characteristics nutritive value compared conventional Among products, heat-treated emulsion-meat sausages widely consumed especially su...

Celecoxib, a selective cyclo-oxygenase – 2 inhibitor has been recommended orally for the treatment of arthritis and osteoarthritis. Long term oral administration of celecoxib produces serious gastrointestinal side effects. Therefore the aim of the present investigation was to assess the potential of nanosized emulsion formulations for transdermal delivery of celecoxib (CXB), to reduce the side ...

In this work, a new methodology was developed to disperse nanofibrillated cellulose (CNF) in polylactic acid (PLA) composites for 3D printing. The nanofibres were modified by grafting PLA onto their surface through in-situ polymerisation of L-lactide. This modification changed subsequent fibre/PLA interaction and enabled the production reinforced microparticles Pickering emulsion approach. We d...
