Characterization of interactions between β-lactoglobulin tryptic peptides and a nanofiltration membrane: Impact on the surface membrane properties as determined by contact angle measurements

High permeate flux of PVA/PSf thin film composite nanofiltration membrane with aluminosilicate single-walled nanotubes

“…The free energy of interaction at the interface between the liquid and the surface (DG SL ) was calculated using Young-Dupré equation (Eq. (3)) [28]:…”

Clay-Containing Polysulfone Nanocomposites

“…m -2 (Lapointe et al, 2005). From SAXRD results (Table 1), it was possible to note that, since MMT presented a basal spacing of 14.8 Å and both diffractograms showed a basal spacing of 13 Å, there was the formation of intercalated nanocomposites.…”

Advancements in the Fractionation of Milk Biopeptides by Means of Membrane Processes

“…Thus, if the valence of the co-ion (zB) has a lower value and the valence of the counter-ion (zA) is increased, the concentration of co-ions in the membrane will be favored. For example, the retention of some common salts by descending order (Na2SO4 > NaCl > CaCl2) through a negatively charged NF membrane can be predicted according to these principles [60][61][62][63].…”
