Asymmetric Electrostrain/Electrobending in Piezoelectric Ceramics: Role of Defect Dipoles or Oxygen Vacancies

open access: yesAdvanced Science, EarlyView.
Defect‐configurational origins of the asymmetric apparent electrostrain are revealed in different piezoelectric ceramics via atomic‐scale visualization of defect configurations. Migration of oxygen vacancies leads to the electrobending effect in N2‐sintered BaTiO3, while defect dipoles in Ba0.99TiO2.99 generate true asymmetric electrostrain without ...

V2CTx MXene as a Sacrificial Promoter for NiFe Catalyst for Anion Exchange Membrane Electrolyzers

open access: yesAdvanced Science, EarlyView.
These findings demonstrate that V2CTx functions beyond passive conductive support as an active electronic participant whose structural legacy sustains durable performance even after vanadium leaching in Anion Exchange Membrane (AEM) Electrolysers. ABSTRACT Nickel‐iron layered double hydroxides (NiFe‐LDH) show excellent activity, their poor conductivity

CO2‐Assisted Hydrolysis of NaBH4: A Multi‐Function Platform for Enhanced Hydrogen Release, Regeneration of NaBH4, and CO2‐to‐CH4 Conversion

open access: yesAdvanced Science, EarlyView.
CO2 significantly accelerates hydrogen release from aqueous NaBH4 without metal catalysts, eliminating the need for downstream separation. Ball‐milling the hydrolytic products with Mg regenerates NaBH4 with yields exceeding 76% while simultaneously producing methane.

An Embodied Paper‐Based Microfluidic Al‐Air Battery for Enduring Untethered Insect‐Scale Robots

open access: yesAdvanced Science, EarlyView.
This work presents a centimeter‐scale microfluidic aluminum–air battery (MFAAB) with dual‐surface anode and F−‐mediated byproduct decomposition. The design enables a high capacity of 2697.05 mAh/g Al and delivers tens of milliwatts to power LEDs, motors, and a toy car.
