Relationship of Dye Adsorption Onto Biomass Activated Carbon Mixed Matrix Ultrafiltration: A Mass Transfer Model Study

open access: yesAdvanced Materials Interfaces, EarlyView.
This study explored dye molecule adsorption from water, focusing on activated carbon in polymer membranes for purifying low‐quality water. Polyvinylidene fluoride (PVDF) membranes showed enhanced removal efficiency of methylene blue (MB) from 89.29% to 98.33% with biomass‐activated carbon (BAC).

Design of high-performance electro-driven nanofiltration membrane via facile co-deposition of pyrogallol and polyethyleneimine for sustainable resource recovery from landfill leachate concentrate

open access: yesAdvanced Membranes
Conventional treatment methods of landfill leachate concentrate mainly focus on the degradation or removal of humic substance, which are prone to secondary pollution and fail to meet the requirements of current sustainable development.

Light‐Programmable Interfaces: From Molecular Photoswitching to Adaptive Membrane Separations

open access: yesAdvanced Materials Interfaces, EarlyView.
This review advances an interface‐centered framework for light‐responsive membranes, linking molecular photoswitches (azobenzene (AZO), spiropyran (SP), diarylethene (DAE), donor–acceptor Stenhouse adducts (DASA), photoacid) to integration strategies in polymeric, porous, self‐assembled, and mixed‐matrix systems.

Scalable Layer‐by‐Layer Electrospray‐Assisted Interfacial Polymerization: Enabling Large‐Area Polyamide Membrane Fabrication

open access: yesAdvanced Materials Technologies, EarlyView.
We report a multi‐jet, layer‐by‐layer electrospray‐assisted interfacial polymerization (LBL‐EAIP) approach for the scalable fabrication of polyamide reverse osmosis (RO) membranes. The method enables precise control of polymerization, uniform polyamide coverage, and tunable polyamide film thickness, while delivering consistently high filtration ...

Preparation and salt rejection properties of THAP/TEPA co-deposited interlayer composite nanofiltration membranes

open access: yesGongye shui chuli
To address the high energy consumption caused by the inherent trade-off effect between permeability and rejection in nanofiltration membranes, an interlayer was constructed to maintain the stability of flux and effectively improve the salt rejection ...

A Contribution for the Valorisation of Sheep and Goat Cheese Whey through Nanofiltration

open access: yesMembranes, 2018
The amount of cheese whey generated from the production of speciality sheep and goat cheese is significantly growing due to the acclaimed nutritional and medicinal benefits of the milk from these species. However, most of the cheese whey generated has no

Preparation of anti-fouling zwitterionic nanofiltration membrane with tunable surface charge

open access: yesAdvanced Membranes, 2022
Anti-fouling property is of vital significance and remains a challenge in the membrane separation field. In this work, N-diethylethylenediamine (DEEDA) was incorporated into the polyamide matrix first.

Recycling wastewater for hydraulic fracturing by use of nanofiltration membranes [PDF]

open access: yes, 2014
Hydraulic fracturing creates large volumes of produced water, contaminated with organics, suspended solids, and dissolved minerals. This water must either be disposed of in injection wells or treated for reuse.
