Novel preparation method of microencapsules was developed on the basis of the liquid coalescence method followed by phase separation. Oil droplets of limonene dissolving expanded polystyrene as a shell material were forced to collide and coalesce with the Isopar oil droplets of core material in the continuous wates phase. When two kinds of oil droplets are collided and coalesced with each other...

The feasibility of fabricating Janus particles based on phase separation between a hard fat and a biocompatible polymer was investigated. The solvent evaporation method used involved preparing an oil-in-water (o/w) emulsion with a mixture of poly (lactic-co-glycolic) acid (PLGA), hard fat, and an organic solvent as the oil phase and a polyvinyl alcohol aqueous solution as the water phase. The J...

Crude oil separation processes involve many high profile control systems and equipment that costing a vast amount of investment. Any mistake in the management will cause serious aftermath. The main focuses in this paper are the design of simulation modelling of an oil production area and is used as planning, controlling and decision making tool with associated factors such as crude oil input ra...

The enantiomeric separation of basic drugs was successfully demonstrated by using a novel chiral microemulsion electrokinetic chromatography (MEEKC). An interesting finding was that the chiral oil core ((S)-(+)-2-octanol) within the microemulsion droplets appeared to play an important role in the chiral separation mechanism. In addition, the enantioselectivity of the analyte-selector complex co...

In this paper, we developed a novel approach for interfacing a microfluidic two-dimensional droplet array to a high-speed capillary electrophoresis (HSCE) system. Picoliter-scale sample injection (ca. 200 pL) from a nanoliter-scale droplet array covered by nonvolatile oil was automatically achieved using the spontaneous injection mode, without the interference from the cover oil and the need of...

Various effects on the separation of raw reaction mixture after the ethanolysis of rapeseed oil were investigated. Water addition, initial temperature of separation, centrifugation, ionic compound addition and time effects affecting concentrations of potassium, free glycerol and yield of the ester phase were found out. Centrifugation has the most positive effect. Finally, correlation between co...

usage of herbal medicine has been under so much attention for many years. they are gradually replacing synthetic drugs in pharmaceutical fields due to their fewer side effects. nowadays, essential oils are widely used for the treatment of diseases as well as being applied as pesticide. in this study, 32 components of zingiber essential oil were identified representing 97.42% of the extracted oi...
