Employing the synergistic effect between aquaporin nanostructures and graphene oxide for enhanced separation performance of thin-film nanocomposite forward osmosis membranes

Construction of facilitated mass transfer composite membranes with triple-layer water nanochannel architecture for forward osmosis process using cGO-coated polysulfone separation membrane as the substrate

“…13. This contributes to better salt rejection performance and lower specific salt flux of the cGO-coated composite membrane than that of most of the GO-blending FO composite membranes reported in previous literature, 30,[56][57][58][59][60] which can be clearly seen in Fig. S5.…”

The coming of age of water channels for separation membranes: from biological to biomimetic to synthetic

“…51 For water-based membrane separation, prominent AQPs include human AQP-1 and bacterial AQP-Z, of which the latter is of interest in membrane fabrication because of its enhanced stability and easier processability as compared to the former. 66,67 Stopped-flow measurements (Fig. 3b and f) have shown that the water permeability of AQP-1 is B2 times higher than that of AQP-Z (refer to Table 1) and most fundamental studies are based on the former.…”

“…The first method is adopted when incorporating biological channels (e.g. AQPs), 63,64,66,223 or unimolecular channels (e.g. pillar [5]arenes), 54 or when the channels are extremely small (o5 nm) and thus unstable when standalone (i.e., this method can preserve the structure and functionality of the nanochannels).…”

Fabrication of high-performance thin-film composite and nanochannel-enabled next-generation membranes for water desalination

“…In the sub-sections 2. and bacterial AQP-Z, of which the latter is of interest in membrane fabrication because of its enhanced stability and easier processability as compared to the former [81,82].…”

“…The first method is adopted when incorporating biological channels (e.g., AQPs) [48,81,123,124], unimolecular channels (e.g., pillar [5]arenes) [101], or when the channels are extremely small (<5 nm) and thus unstable when standalone (i.e., this method can preserve the structure and functionality of the nanochannels). In the current literature, this type of TFN membrane is sometimes termed as biomimetic membrane [71].…”
