Modelling nanofiltration of electrolyte solutions

open access: yesAdvances in Colloid and Interface Science, 2019
This review critically examines current models for nanofiltration (NF) of electrolyte solutions. We start from linear irreversible thermodynamics, we derive a basic equation set for ion transfer in terms of gradients of ion electrochemical potentials and transmembrane volume flux.

Enhancing Binding by Electron Transfer at Heterointerfaces of Biochar‐Modified Hydrogel to Improve Utilization Efficiency of Wastewater Recovered Nutrients

open access: yesAdvanced Science, Volume 13, Issue 16, 18 March 2026.
Enhancing the utilization efficiency of nutrients recovered from wastewater is achieved through hydrogel modification by biochar. The strategy improves nutrient binding to hydrogels via electron transfer at heterointerfaces, thereby reducing nutrient release rate.

Atomically Thin Sieves: Two‐Dimensional Materials for Membrane Separation

open access: yesAdvanced Physics Research, Volume 5, Issue 3, March 2026.
Atomically thin membranes derived from 2D materials overcome the inherent selectivity‐permeability trade‐off in conventional separation technologies. This perspective elucidates transport mechanisms for gases, water, and ions, surveys fabrication strategies including top‐down pore engineering and bottom‐up synthesis, highlights recent experimental and ...

Comparison of the performance of two reverse osmosis membranes for the final purification of olive mill wastewater [PDF]

open access: yes, 2015
Two quite different reverse osmosis (RO) polymeric membranes were examined for the final purification of olive mill wastewater from two-phase olive mills (OMW2): the first one is a thin-film composite (TFC) membrane consisting of polyamide active layer ...
