Liposomes are widely used as drug delivery systems in different forms including osmotic pumps, infusion and IV injection. In spite of these, there is no data available about their behavior under convective flow (e.g. infusion or osmotic pumps) and upon stagnation in such drug delivery systems. As a part of a series of investigations in this area, the present study investigates the effects of vi...

aqueous two-phase systems (atps) have  emerged as a powerful extraction method for the downstream processing of bio-molecules. the aim of this work was to investigate the possibility of utilizing atps for the separation of recombinant bacillus sphaericus phenylalanine dehydrogenase (phedh). polyethylene glycol (peg) and ammonium sulfate systems were selected for our experiment. the effect of di...

Phase separation simulation study related to cellulose acetate-water-acetone has been done. Results show that porous asymmetric and symmetric membranes can be produced by changing the nonsolvent concentration or by the drying conditions without altering the polymer content using dry-casting process. Dry-casting process is the process in which complete evaporation of solvent and nonsolvent takes...
