objective: evaluation activity was conducted using three spearmint genotypes (wg-spm-engl, spm-fran and spm-eas) and one standard check (wgsm-03) at wondo genet, awassa, debre zeit and allagae during 2012 and 2013 for two years. methods: the treatments were arranged in randomized complete block design with four replications. data on leaf to stem ratio, leaf yield/ha, essential oil content and e...

In this study, encapsulation of agarwood oil with non-ionic surfactant, Tween 80 was prepared at critical micelle concentration of 0.0167 % v/v to produce the most stable nano-emulsion in aqueous. The encapsulation has minimized the bioactive compounds degradation in various pH conditions thus prolong their shelf life and maintained its initial oil grade. The oil grading of the prepared samples...

Lemongrass oil and d-limonene are typical flavor oils used in the food and cosmetic industries. Lemongrass oil displays some therapeutic properties such as analgesic, antimicrobial, fungicidal, deodorant, etc. Citral, the main active component of lemongrass oil, consists of a mixture of two isomeric acyclic monoterpene aldehydes: geranial and neral. Molecular encapsulation of these flavors was ...

Capillary microfluidic devices are used to prepare monodisperse polymersomes consisting of a hydrogel core and a bilayer membrane of amphiphilic diblock-copolymers. To make polymersomes, water-in-oil-in-water double-emulsion drops are prepared as templates through single-step emulsification in a capillary microfluidic device. The amphiphile-laden middle oil phase of the double-emulsion drop dew...

Oil-chitosan composite spheres were synthesized by encapsulation of sunflower seed oil in chitosan droplets, dropping into NaOH solution and in situ solidification. Hydrophilic materials (i.e., iron oxide nanoparticles) and lipophilic materials (i.e., rhodamine B or epirubicin) could be encapsulated simultaneously in the spheres in a one step process. The diameters of the prepared spheres were ...

The manipulation of cells inside water-in-oil droplets is essential for high-throughput screening of cell-based assays using droplet microfluidics. Cell transfection inside droplets is a critical step involved in functional genomics studies that examine in situ functions of genes using the droplet platform. Conventional water-in-hydrocarbon oil droplets are not compatible with chemical transfec...
