Oxygen permeation membrane

WebOxygen permeability. Oxygen permeability ( OP) is a parameter of a contact lens that expresses the ability of the lens to let oxygen reach the eye by diffusion. In soft contact lenses, it is dependent on the thickness of the lens and the material of the lens, especially concerning the water content. Because of this dependence on thickness ... WebSelective oxygen separation from air was carried out using ceramic membranes composed of Ba0.95La0.05FeO3-δ. We demonstrated that surface abrasion of Ba0.95La0.05FeO3-δ membranes led to a significant increase in oxygen permeation fluxes at 700−930 °C because of an increase in surface reaction sites. Abrasion of the oxygen desorption side …
