網頁2024年5月10日 · The modified membrane (M-12C4-0.50-PEI) exhibits significantly prominent selectivity to Li + ions ( = 5.23) and K + ions ( = 13.56) in Li + /Mg 2+ and K + /Mg 2+ systems in electrodialysis (ED), which is far superior to the pristine membrane (M-0, = 0.46, = 1.23) at a constant current density of 5.0 mA·cm −2. 網頁The channel is composed of four protein subunits that are assembled in a predetermined arrangement and stoichiometry (α2βγδ) around a central, cation‐selective pathway. Transmembrane segments of the AChR subunits like those of other channels are mainly formed by 19–21 amino acid residues that are folded into a α helix.
