1365por Shin, Sung-Hee, Nur, Pratama Juniko, Kodir, Abdul, Kwak, Da-Hee, Lee, Hyejin, Shin, Dongwon, Bae, Byungchan“…Five types of solution-cast membranes were produced from commercial perfluorinated ionomers (3M and Aquivion (AQ)) with different equivalent weights, annealed at different temperatures, and characterized in terms of ion conductivity, water uptake, and in-plane/through-plane swelling, while the effect of annealing on physical structure of membranes was evaluated by small-angle X-ray scattering and dynamic mechanical analysis. To create a reinforced composite membrane (RCM), we impregnated a polytetrafluoroethylene porous support with 3M 729 and AQ 720 electrolytes exhibiting excellent proton conductivity and water uptake. …”

Yet the dynamical mechanisms needed to generate a population code based on transient trajectories have not been fully elucidated. …”
