Objective: The objective of the present study was to develop and optimize Astragalin-loaded polymeric nanoparticles (AST-NPs) using a central composite factorial design (CCD). Methods: AST-NPs were prepared by dialysis method. CCD employed influence formulation factors, polymer concentration, aqueous organic phase ratio, process parameter stirring time on dependent physicochemical characteristi...

To produce biodiesel, one of the most important factors is quality oil used in production. However, other such as price and availability should also be taken into consideration. Chicken wastes shows a very promising option for this sector, since it comes from waste. The aim present study was methodology extraction characterization chicken production biodiesel by ethylic transesterification, bes...
