## Abstract Dense membranes made of poly(vinyl alcohol) (PVA) and poly(__N__βvinylβ2βpyrrolidone) (PVP) blends of different compositions were studied in gasβsweeping permeation of a waterβethanol mixture containing 10 wt.β% of water. When the PVP content increases, the steadyβstate permeation flux
Nitric oxide (NO) is responsible for biological actions in mammals, ranging from the control of arterial pressure to immunological responses. In this study, Snitrosoglutathione (GSNO), a spontaneous NO donor, was incorporated in solid films of blended poly(vinyl alcohol) (PVA) and poly(vinyl pyrroli
