Formulation and characterisation of cationic microparticles for the delivery of DNA vaccines
… The cationic polymers chitosan and poly (N- vinylpyrrolidone/2-dimethylaminoethyl methacrylate), dimethyl sulfate quaternary (PVP-PDAEMA) were investigated as alternative stabilisers to CTAB. From a variety of initial formulations, the most promising vector(s) for DNA vaccination were …

Characterization and interphase mechanical properties of epoxy/PVP blends
Applying sizing material (poly n-vinylpyrrolidone or PVP) around graphite fibers enhances the mechanical properties of carbon fiber reinforced epoxy composites. Understanding the influence of the interphase region between the carbon fiber and epoxy matrix is crucial in enhancing the performance of …
