    Abstract: A polymeric fiber for use in gas separation is formed from a spin dope which includes solvent and non-solvent materials. The fiber is passed through a quench bath, and then a leach bath, in which the solvent and non- solvent are removed. The quench bath and the leach bath include sets of rollers which transport the fiber through the system. Each set of rollers in the leach bath operates at a speed which is greater than or equal to the speed of the rollers which are immediately upstream. Thus, the fiber is stretched, in different amounts, at the same time that the solvent and non- solvent are being removed, and while the fiber is still wet. The resulting fiber has been found to exhibit superior flux and selectivity properties.

    Abstract: A method for producing a nozzle useful in generating a fine aerosol for delivery of a therapeutic or diagnostic agent is provided. The method comprises treating a thin, preferably flexible material having partially formed nozzles with a plasma which alters the size and shape of the nozzles. The pores in the nozzles so formed preferably have an unflexed exit aperture diameter in the range of about 0.5 to about 25 microns, depending on the size of the aerosol particles desired for a given application. The pores in the nozzles can have a variety of shapes and can be distributed in a variety of patterns. An elevated area can be formed around the exit aperture of the nozzle in order to prevent intrusion of liquid back into the nozzle. A method of producing an aerosolization device incorporating such a nozzle is also provided.
