nanofibrous scaffolds produced by electrospinning have attracted much attention, recently. aligned and random nanofibrous scaffolds of poly (vinyl alcohol) (pva), poly (ε-caprolactone) (pcl) and nanohydroxyapatite  (nha) were fabricated by electrospinning method in this study. the composite nanofibrous scaffolds were subjected to detailed analysis. morphological investigations revealed that the...

Poly(vinyl alcohol) (a), its partially hydrolyzed product or poly(vinyl alcohol-co-vinyl acetate) (b) and poly(ethylene-co-vinyl alcohol) (c) are all industrially significant polymers used mainly for fiber and film, size and emulsifier/stabilizer, and gas-barrier material, respectively. In this thesis, these vinyl alcohol-based polymers have been discussed from two aspects: the molecular struct...

A micro-capillary film has been developed that offers the potential for an at-line analytical tool for rapid aggregate analysis during biopharmaceutical antibody production. A non-porous walled micro-capillary film (NMCF) with cation exchange functionality was demonstrated to act as a chromatography medium that could be operated with high linear fluid velocities and was highly resistant to bloc...
