Diffusive transport through nanoporous alumina membranes (NPAMs) produced by the two-step anodization method. with similar pore size but different porosity. is studied by analyzing membrane potential measured with NaCl solutions at different concentrations. Donnan exclusion of co-ions at the solution/membrane interface seem to exert a certain control on the diffusive transport of ions... https://jalyttlers.shop/product-category/wedding-card/
