Nanoconfinement Engineering of Covalent Organic Frameworks in Polyamide Membranes for High‐Perselectivity Li+/Mg2+ Separation

Advanced Science, EarlyView.
A nanoconfinement strategy using porous COF layers is developed to regulate interfacial polymerization and prepare thin, uniform PA membranes. The COF layer provides confined spaces and abundant interaction sites, effectively controlling monomer distribution and reaction kinetics.

Natural Toolbox–Chemical Engineering Aspect and High‐Value Applications of Janus Cellulose Nanomaterials

Advanced Science, EarlyView.
The Tai Ji symbol from China represents the co‐existence of two opposite substances, similar to quantum entanglement. The term Janus comes from ancient Roman religion and mythology. Janus, the god of beginnings, transitions, etc., has two faces, symbolizing duality. Janus cellulose nanomaterials show structural duality.

Turning Microstructure in Block Copolymer Membranes: A Facile Strategy to Improve CO2 Separation Performance

Advanced Science, EarlyView.
A simple and effective non‐solvent‐induced microstructure rearrangement (MSR) technique is proposed to enhance the gas separation performance of Pebax 2533 membranes. By immersing Pebax 2533 membranes in amino acid salt solutions to induce MSR, the CO2 permeability of the Pebax 2533‐GlyK 10 wt.% membrane reached 1180 Barrer.
