Valence‐Engineering of CeO2 Redox Modulator Boosts the Oxygen Electrocatalysis Performance in Fe/Co Dual‐Atom Catalyst

open access: yesAdvanced Science, EarlyView.
Valence‐engineering of CeO2 redox modulator can remove the highly oxidative by‐products and accelerate the oxidation state transitions of Co/Fe centers in FeCo dual‐atom catalyst during oxygen reduction/evolution electrocatalysis. Therefore, the stability and activity issues are resolved, significantly enhancing the overall performance when used as an ...

Hierarchical Strain‐Modified Medium‐Entropy Carbide Ceramics Exhibit Exceptional Ablation Resistance up to 2400°C

open access: yesAdvanced Science, EarlyView.
A novel strategy is developed by doping reduced graphene oxide (rGO) into a (HfZrTi)C medium‐entropy ceramic. This induces a hierarchical strain modification mechanism, synergistically inhibiting crack propagation at the microscale and dissipating stress at the mesoscale.

Improved Air Stability of Li Argyrodites Through PS43− Rotation Suppression by Al and Se Co‐Substitution for All‐Solid‐State Batteries

open access: yesAdvanced Science, EarlyView.
Al/Se co‐substitution in Li6PS5Cl achieves enhanced dry‐air stability and improves Li+ conductivity, retaining 85% of its high Li+ conductivity (4.91 mS cm−1 at 30 °C) after dry‐air exposure (dew point −40 °C for 5 h). The stability enhancement is experimentally validated and underpinned by theoretical analyses indicating suppressed rotation of P[S2SeO]

Scrambling‐Enhanced Quantum Battery Charging in Black Hole Analogues

open access: yesAdvanced Science, EarlyView.
By employing a black‐hole‐analog quantum battery constructed from a position‐dependent XY model, its dynamical behavior is investigated through a quench of the scrambling parameter. It is systematically quantified that how the simulated scrambling improves key performance metrics‐namely, stored energy, peak power, and charging time‐thereby offering a ...
