Enhanced Electromechanical Response in 1D Hybrid Perovskites: Coexistence of Normal and Relaxor Ferroelectric Phases

open access: yesAdvanced Functional Materials, EarlyView.
The dynamic polarization reversal of coexisting normal and relaxor ferroelectrics in 1D TMAPbI₃ (tetramethylammonium, TMA) is deciphered through combined experimental and theoretical approaches. By bridging atomic‐scale motion, macroscopic polarization switching, and depolarization effects, a universal methodology is established to engineer next ...

Boosting Polysulfide Conversion on Fe‐Doped Nickel Diselenide Toward Robust Lithium–Sulfur Batteries

open access: yesAdvanced Functional Materials, EarlyView.
This work reports an advanced functional material based on Fe‐doped nickel diselenides toward robust lithium–sulfur batteries, demonstrating that Fe‐rich cores and surface doping enhance the density of states at the Fermi level and introduce unpaired electrons for the improvement of the LiPS adsorption and catalytic conversion. Abstract Sulfur offers a

Low‐Surface‐Energy Copper Promotes Atomic Diffusion and Ordering in PtFeCu Intermetallic Compounds for Oxygen Reduction Catalysis

open access: yesAdvanced Functional Materials, EarlyView.
A copper‐induced atom ordering strategy is developed for the reconstruction of raw commercial Pt catalyst into ordered PtFeCu intermetallic compounds for hydrogen fuel cells. Abstract Carbon‐supported platinum intermetallic compound nanoparticles are seen as the next‐generation cathodic catalysts for hydrogen fuel cells due to their high activity and ...

Photoactivation of NV Centers in Diamond via Continuous Wave Laser Illumination of Shallow As‐Implanted Nitrogen

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates an alternative method of creating charge‐stable negatively charged nitrogen vacancy (NV−) centers close to the diamond surface without high‐temperature annealing. By illuminating nitrogen‐implanted regions with a continuous‐wave 405 nm laser, NV− centers are induced, exhibiting electron spin coherence properties suitable for ...

Ultrafast Room‐Temperature Nanofabrication via Ozone‐Based Gas‐Phase Metal‐Assisted Chemical Etching for High‐Performance Silicon Photodetectors

open access: yesAdvanced Functional Materials, EarlyView.
Ozone‐based gas‐phase metal‐assisted chemical etching enables unprecedented room‐temperature fabrication of high‐quality silicon nanowires. The superior oxidation potential of O3 drives rapid vertical etching (1 µm min−1) while maintaining exceptional structural integrity. The pristine nanowire surfaces enable high‐performance core‐shell photodetectors
