the aim of the present study was to investigate the potential of nanoemulsion formulation for topical delivery of clobetasol propionate (cp) using algal oil (containing omega-3 fatty acids) as the oil phase. cp has anti-inflammatory, immunomodulatory and antiproliferative activities. however, its clinical use is restricted to some extent due to its poor permeability across the skin. algal oil w...

The feasibility of extractive reaction of methacrylic acid from aqueous solution using a quaternary amine, tri–octyl methyl ammonium chloride (TOMAC) as an extractant, was studied. The diluents chosen in the present work belong to different chemical classes, n–butyl acetate, carbon tetrachloride, isoamyl alcohol, methyl isobutyl ketone, and toluene. The effect of initial acid concentration in t...

We report a simple and convenient method for fabricating ordered porous structure in a polymeric thin film. A temporarily stabilized water-in-oil emulsion, where aqueous droplets were dispersed in the medium of polymer-organic solvent solution, was utilized for the preparation of porous structure. The water-in-oil emulsion was simply prepared by sonicating the mixture of water and polymer-organ...

The effect of calcium on the dissolution and microbial reduction of a representative solid phase uranyl [U(VI)], sodium boltwoodite (NaUO(2)SiO(3)OH . 1.5H(2)O), was investigated to evaluate the rate-limiting step of microbial reduction of the solid phase U(VI). Microbial reduction experiments were performed in a culture of a dissimilatory metal-reducing bacterium (DMRB), Shewanella oneidensis ...

The development of modern therapeutics has raised the requirement for controlled drug delivery system which is able to efficiently encapsulate bioactive agents and achieve their release at a desired rate satisfying the need of the practical system. In this study, two kind of aqueous model drugs with different molecule weight, Congo red and albumin from bovine serum (BSA) were nano-encapsulated ...

We investigated hydrothermal liquefaction of Nannochloropsis sp. at different temperatures (250e400 C), times (10e90 min), water densities (0.3e0.5 g/mL), and biomass loadings (5 e35 wt %). Liquefaction produced a biocrude with light and heavy fractions, along with gaseous, aqueous, and solid by-product fractions. The gravimetric yields of the product fractions from experiments at 250 C summed ...
