a
Improvement in permselectivity is calculated relative to performance of TFC membrane reported in the related study. Details are given in Table S6.
b
Hydraulic pressure difference and NaCl concentration of the feed solution.
c
Pure or salt water flux is reported. Note that this is considered in the calculation of permeability coefficients.
d
The abbreviation D stands for diameter.
