Viscosity molecular weight determination of polyadenylic acid
(1995)
In this study viscosity measurements of polyadenylic acid (PolyA) in aqueous solution were carried out under different conditions. In the absence of any additives, the polymer degraded during flow through the capillary of ...
Diffusion and selective transport of alkali cations in a polysulfone ion exchange membrane
(Gauthier-Villars, 1995)
he diffusion of alkali metals through a charged polysulfonated ICE-450 ion exchange membrane has been measured as a function of pH and conservation of the external solution at 25 degrees C. The permeability and diffusion ...
