High Free‐Volume Imidazole‐Based Ionomers for High‐Temperature Proton Exchange Membrane Fuel Cells

open access: yesAdvanced Science, EarlyView.
High free‐volume imidazole‐based ionomers (PF4IM‐72) enable enhanced phosphoric acid uptake and efficient proton transport, delivering peak power densities of 0.645 W cm−2 at 160 °C and 0.838 W cm−2 at 200 °C in HT‐PEMFCs. This work highlights a promising platform for next‐generation ionomers with improved high‐temperature performance and stability ...

Strain‐Modulated Reconfigurable Optical Information Processing in Flexible Graphene/PDMS

open access: yesAdvanced Science, EarlyView.
Graphene/PDMS—a stable, mechanically robust, and highly tunable flexible composite, exhibits excellent strain‐tunability. The spatial self‐phase modulation (SSPM) effect can be reversibly and continuously modulated by strain. A strain‐gated optical switch can be constructed, thereby realizing reconfigurable optical logic gates and reversible switching ...

Multiferroic‐Centric Materials and Systems Engineering for Battery Applications: An Insight Into Mechanisms, Strategies, and Characterizations

open access: yesAdvanced Science, EarlyView.
Multiferroic order parameters – polarization, magnetization, and ferroelastic strain – are positioned as dynamic design variables for batteries. Their mechanistic roles, practical tuning through fabrication and external fields, and ferroic‐resolved characterization routes are unified into a closed‐loop framework, revealing how coupled ferroic responses
