Preparation of Biopolymeric Nanofiber Containing Silica and Antibiotic

preparation, characterization and cytotoxic effects of silica nanoparticles containing epirub

Preparation and characterization of biopolymeric nanoparticles used in drug delivery.

Nanotechnology plays an important role in advanced biology and medicine research particularly in the development of potential site-specific delivery systems with lower drug toxicity and greater efficiency. These include microcapsules, liposomes, polymeric microspheres, microemulsions, polymer micelles, hydrogels, solid nanoparticles etc. In the present study, preparation and characterization of...

Fermentative preparation of S35-siomycin, a sulfur-containing peptide antibiotic.

rpm). An inoculum of 5-8 % of the rusulting seed broth was then used to inoculate the fermentation flasks. The composition of the fermentation mediumwas as follows : sucrose 7 %, soybean meal 2.5 %, ammonium sulfate 0.3 %, pH 7.0, 25 ml of medium being used per 200ml flask. The fermentation was carried out on a rotary shaker at 200 rpm for about 10 days at 30°C. Feeding of S35-ammonium sulfate ...

exploring motivation and english test preparation strategies of iranian pre-university candidates during and at the end of test preparation period for konkur examination

the current study aimed at investigating the relationship between motivation and test preparation strategies (tpss) used by iranian pre-university students in their preparation period for the university entrance exam (uee). due to the importance of uee in iran, this study also attempted to show its impact on these two important variables. to this end, 100 pre-university students in an iranian p...

Preparation of aluminum-containing mesoporous silica with hierarchical macroporous architecture and its enhanced catalytic activities.

Aluminum-containing mesoporous silica with hierarchical macroporous architecture (Al-MMS) was successfully prepared using a solvent evaporation method through the combination of precursor solution for synthesis of Al-containing mesoporous silica (Al-MS) and poly(methyl methacrylate) (PMMA) colloidal crystals as a hard template. The porous structure and the state of aluminum were investigated us...

Preparation and Characterization of Heterogeneous PVC-Silica Proton Exchange Membrane

Heterogeneous proton exchange membranes (PEM) are synthesized using the dry phase inversion technique. The casting solutions are prepared by dispersing a finely ground cation exchange resin particle in N,N-dimethylacetamide (DMAc) solution of polyvinyl-chloride (PVC). Results show that ion exchange capacity is increased with the addition of 1 %-wt nanosilica (from 0.14 to 0.27 meq/g) while it i...
