Solid lipid nanoparticles (SLN) loaded with doxorubicin were prepared by solvent emulsification-diffusion method. Glyceryl caprate (Capmul)MCM C10) was used as lipid core, and curdlan as the shell material. Dimethyl sulfoxide (DMSO) was used to dissolve both lipid and drug. Polyethylene glycol 660 hydroxystearate (Solutol)HS15) was employed as surfactant. Major formulation parameters were optim...

In this work we provide a basic physical modeling of the spatiotemporal pattern of emulsification produced by chemical reaction-driven tip-streaming and observed by Fernandez and Homsy @Phys. Fluids 16, 2548 ~2004!#. Features of this phenomenon—nonlinear autooscillations, a conical drop shape, tip-streaming, and droplet trajectory splitting—are addressed in this paper. In particular, the experi...

Demulsification is an aggressive phase-separation phenomenon of stable emulsions. Several studies have examined demulsification by chemical reactions using external stimuli, such as temperature variation, pH variation, and light irradiation. This study focused on the interfacial and emulsification properties of light-responsive surfactants because the use of light as an external stimulus is rel...

Phasins are unusual amphiphilic proteins that bind to microbial polyhydroxyalkanoate (PHA) granules in nature and show great potential for various applications in biotechnology and medicine. Despite their remarkable diversity, only the crystal structure of PhaPAh from Aeromonas hydrophila has been solved to date. Based on the structure of PhaPAh , homology models of PhaPAz from Azotobacter sp. ...

Emulsions are widely used in food industry, among others. Monosized droplets in emulsions have advantages for control of their properties, and application fields. We have developed microchannel emulsification (MC) technology for monosized droplets formation. The grooved type MC and module were used to characterize MC emulsification, and straight-through MC and module were developed for higher p...

Deparaffinization is one of the stages tissue processing, which aims to dissolve paraffin for full-color application. can only be done by xylol as fat. Liquid laundry detergent has main component in form a surfactant property removing types lipids dissolving and emulsification because carcinogenic properties, flammable relatively expensive. This study aimed describe quality preparations using l...

With the objective of making calcium alginate gel beads with small and uniform size, membrane emulsification coupled with internal gelation was proposed. Spherical gel beads with mean size of about 50 m, and even smaller ones in water, and with narrow size distribution were successfully obtained. Experimental studies focusing mainly on the effect of process parameters on bead properties were pe...

The selective separation of aromatics (benzene, toluene and p-xylene, BTX) from aliphatic (n-heptane) is investigated using simple permeation and facilitated transport emulsion liquid membrane mechanism. The separation performances, represented by the permeation rate and separation factor, are analyzed systematically by varying the operating parameters. One of the major obstacles to the applica...
