Polar Pore Surface of Polyamide Membranes Enabling Efficient Solvent Mixture Separation

Advanced Functional Materials, Volume 35, Issue 23, June 5, 2025.
A polyamide membrane with polar pore surfaces and relatively large pore is fabricated through interfacial polymerization between polyethyleneimine and trimesoyl chloride. Rapid separation of solvents with polarity differences is achieved by the synergistic effects of pore polarity and size sieving.

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

Automated multistep organic synthesizer based on organic solvent nanofiltration: OSN-Syn

Functional Group Searcher One of the central goals of automated synthesis is the on-demand construction of compound libraries directly from commercially available building blocks. To support this, we developed a Python program—Functional Group Searcher (see Supplementary_Material_files\Functional_group_searcher\Functional_group_searcher.py)—that ...
