Exploring the potential of commercial polyethylene membranes for desalination by membrane distillation
TL;DR: In this paper, the potential of utilizing polyethylene (PE) membranes in membrane distillation (MD) for sea water desalination has been explored in this study. And the advantages of using PE membranes are (1) their intrinsic hydrophobicity with low surface energy of 28 −33 −10−3 n/m, (2) good chemical stability and low thermal conductivity and (3) their commercial availability that may expedite the MD commercialization process.

The four tiers of structure in integrally skinned phase inversion membranes and their relevance to the various separation regimes
TL;DR: There are four superimposed tiers of structure in integrally skinned phase inversion membranes: macromolecules (functionally sub-macromolescules, that is, displacements between chain segments); nodules (nodule interiors are denser than interstitial regimes, therefore, chain segment displacements within and between nodules differ and hence constitute a bimodal pore size distribution which may account for the dual mode sorption and permeation of gases; transport of water in reverse osmosis occurs primarily through the less dense interstitial domains); nod
