Building Sulfone Bridges: Multi‐Technique Analysis of Thermally Induced Cross‐Linking in Highly Sulfonated Poly(Phenylsulfone)

open access: yesJournal of Polymer Science, EarlyView.
Highly sulfonated poly(phenylsulfone) undergoes controlled thermal cross‐linking through sulfone bridge formation, exploiting the dual role of sulfonic acid groups as both proton‐conducting functionalities and reactive precursors. The resulting fluorine‐free membranes exhibit enhanced hydrolytic, thermal, and mechanical stability while maintaining ...

Bifunctional Electrocatalysts in Rechargeable Lithium‐Gas Batteries: Material Evolution and Mechanistic Insights from Metal‐Free Carbons to Carbon‐Supported Single‐Atom Sites

open access: yesSmall, EarlyView.
This review charts the material evolution of bifunctional electrocatalysts for rechargeable lithium‐gas batteries. It highlights the journey from heteroatom‐doped, metal‐free carbon architectures to precision‐engineered carbon‐supported single‐atom sites. The discussion focuses on mechanistic insights into how these catalysts govern reversible O2, CO2,

Individualization and Purification of Carbon Nanothreads

open access: yesSmall, EarlyView.
Reductive dissolution enables the solution processing of carbon nitride nanothreads into individualized nanothreads that can be assembled into ultrathin films. The resulting interconnected networks exhibit weakly semiconducting behavior, with the conductivity decreasing by only ∼40% from room temperature to 2 K.

An Efficient Sodium Borate‐Based Electrolyte Additive to Activate Sulfur Conversion and Stabilize Calcium Anodes in Calcium−Sulfur Batteries

open access: yesSmall, EarlyView.
Calcium−sulfur (Ca−S) batteries are promising candidates for sustainable energy storage; yet their development is limited by the lack of efficient electrolytes. Here, a sodium‐ion modified Ca[B(hfip)4]2 electrolyte enables reversible room‐temperature Ca−S batteries by simultaneously improving Ca plating/stripping stability and reversible sulfur ...

Solvent‐Responsive Porous Organic Cage‐Based Membranes With Switchable Pore Openings for Molecular Sieving and Heavy Metal Recovery

open access: yesSmall, EarlyView.
An in situ fabricated porous organic cage membranes (PCM) exhibits reversible solvent pore switching property in response to water and methanol. Water stimulated structural rearrangement enables selective removal of Rh B and heavy metal ions (Ni2+ and Zn2+), whereas methanol stimulates the pore expansion promotes Ni2+ and Zn2+ ions recovery.
