Template‐Free Fabrication of Single Atom Fe‐Based Cathodes Unlock High‐Performing Anion‐Exchange Membrane Fuel Cells

open access: yesAdvanced Science, EarlyView.
A high‐performance single‐atom critical‐raw‐material (CRM)‐free Fe‐based catalyst is designed using a template‐free manufacturing approach. This single‐atom catalyst (SAC) is incorporated into operando anion‐exchange membrane fuel cells using O2 and CO2‐free air displaying excellent performance.

Spontaneous Strain‐Spin Transition Coupling Molecular Crystal with Thermal Magnetic Memory Effect, Anisotropic High‐κ and Switchable Dielectric Permittivity

open access: yesAdvanced Science, EarlyView.
A radical salt undergoes a paraelastic‐ferroelastic phase transition, which is coupled with spin‐Peierls transition, resulting in it integrating self‐strain, spin bistability, switchable dielectric and high‐ properties. Abstract Materials that exhibit controllable changes in electrical, magnetic, or spontaneous strain properties, particularly those ...

Boosts in Polarization and Piezoelectric Responses of Lead‐Free Ferroelectrics through Strain‐Enhanced Glassy Coexistent Polars with High Dynamics

open access: yesAdvanced Science, EarlyView.
An effective strategy by constructing strain‐enhanced glassy coexistent polars near ferroelectric tricritical point to simultaneously improve polarization response and reduce energy loss is uncovered in (Ba0.84Ca0.16)0.985Bi0.01(Ti0.9Zr0.07Sn0.03)1‐x/100Hfx/100O3 (xHf) system and verified by phase‐field simulations with supporting high resolution ...
