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

Advanced 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).

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

Advanced 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

Advanced 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 ...

Removal of Homogeneous Precious Metal Catalysts via Organic Solvent Nanofiltration

Chemical Engineering Transactions, 2016
In homogeneous catalysis often precious transition metal complexes are used. Ideally the used catalyst in a specific process is recovered in the downstreaming and recycled back to the reactor. In contrast to the separation of heterogeneous catalysts, the

Reduced‐Graphene Oxide Nanofiltration Membranes Intercalated by Conjugated Polyaromatics: Towards High Monovalent Salt Rejections

Advanced Science, EarlyView.
We demonstrate the fabrication of a series of reduced‐GO nanofiltration membranes containing intercalated polyaromatic conjugated molecules of different structural classes. These tuned‐nanochannel membranes perform “deep nanofiltration” with remarkably high monovalent salt rejections and near‐total divalent salt rejections in a large concentration ...
