Arrested Phase Separation Enables High-Performance Keratoprostheses.

Corneal transplantation is impeded by donor shortages, immune rejection, and ethical reservations. Pre-made cornea prostheses (keratoprostheses) offer a proven option to alleviate these issues. Ideal keratoprostheses must possess optical clarity and mechanical robustness, but also high permeability, processability, and recyclability.

In Situ Polymerization of Ionic Liquid with Tunable Phase Separation for Highly Reversible and Ultralong Cycle Life Zn-Ion Battery.

Severe Zn dendrite growth and side reactions greatly limit the application of aqueous zinc-ion batteries. Herein, we design a layer of polyionic liquid (PCAVImBr) film with a tunable pore size and charge density on the Zn anode to endow homogenized distribution of an electronic field, acerated Zn permeation, and inhabitation of water entry. Such an optimal combination is achieved via a polymerization induced phase separation strategy, where the enhanced cross-linking density arrests the phase separation in a shallow depth and vice versa.

Polystyrene sulfonate threaded in MIL-101Cr(iii) as stable and efficient acid catalysts.

A series of polystyrene sulfonate threaded in MIL-101Cr(iii) composites both with and without cross-linkers were synthesized. These composites demonstrated superior activity and durability for the acid catalyzed reaction, thus highlighting the importance of surface properties, mobility and accessibility of active sites in determining the catalytic performance.
