High‐Entropy Alloys and Oxides as Supercapacitor Electrodes: A Structural and Electrochemical Perspective for Energy Storage

open access: yesAdvanced Sustainable Systems, EarlyView.
This study compares the electrochemical performance of high‐entropy alloys (HEA) and oxides (HEO) as supercapacitor electrodes. HEO demonstrates superior energy and power density due to its capacitive behavior and surface redox reactions, while HEA relies on diffusion‐controlled processes.

A Promising MM–Fe–Al–Ga–B Permanent Material with Substantially Boosted Magnetic Performance

open access: yesAdvanced Science, EarlyView.
A facile two‐step strategy, Al‐doping toward high‐(BH)max followed by Nd/Pr‐based grain boundary diffusion processing toward high‐Hcj, endows the microcrystalline MM–Fe–Al–Ga–B magnet with substantially boosted magnetic performance [(BH)max = 28.02 MGOe, Hcj = 10.14 kOe].

New Insights into Heavy Metal Sequestration Through Metal‐Phenolic Network‐Confined Nano‐HFO: Overlooking Iron Utilization and Modulating Electron Density

open access: yesAdvanced Science, Volume 12, Issue 22, June 12, 2025.
Iron‐based nanocomposites are widely used for trace heavy metal removal, but the low utilization of HFO nanoparticles remains a challenge. Here, a metal‐phenolic network (MPN) strategy is proposed to confine nano‐HFO within polystyrene beads, creating a negative electrostatic field and optimizing electron density at oxygen sites. This approach enhances

Instant Writing of Conductive Interface on MOF Single Crystal by Ultrafast Laser

open access: yesAdvanced Science, EarlyView.
Current device fabrication strategies lack capacity for tailoring ideal electrical interface in individual MOF single crystals. An ultrafast laser approach is developed that in situ constructs stable conductive interface on MOF single crystal scale while maintaining its crystalline integrity.
