In this study, the surface of poly(epsilon-caprolactone) (PCL) scaffold was modified by chitosan (CS) in order to enhance its cell affinity and biocompatibility. It is demonstrated by scanning electronic microscopy (SEM) that when 0.5-2.0 wt% chitosan solutions are used to modify the PCL scaffold, the amount of adhesion of the fibroblasts on the(More)
In order to develop scaffolds with improved biocompatibility for cell culture, hybrid scaffolds were fabricated by modifying poly(epsilon-caprolactone) (PCL) with silk fibroin (SF) in a porous structure. Scanning electronic microscopy revealed that the morphology of the PCL-SF hybrid scaffold was affected by the concentration of the SF solution.(More)
A mathematical model of the PAC-UF membrane flux through a number of factors and quantitative characterization, based on Darcy's law, has been derived. Meanwhile, PAC-UF combined process was applied to treat Gan River micro-polluted raw water. Validity of the mathematical model is verified with the experiment. Furthermore, for different operation pressure(More)
