Control of Covalent Bond Enables Efficient Magnetic Cooling

open access: yesAdvanced Materials, Volume 38, Issue 7, 2 February 2026.
Giant and reversible magnetocaloric effect (MCE) is achieved by tuning covalency through sub‐unit‐cell chemical engineering, establishing a novel design principle for effective hysteresis control in magnetocaloric materials. Abstract Magnetic cooling, harnessing the temperature change in matter when exposed to a magnetic field, presents an energy ...

Ultra‐Improved Interfacial Strength Between Metallic Surface and Polyurethane via Cost‐Effective Anodizing Process

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 4, 17 February 2026.
SAA significantly enhanced Al/PU bonding, increasing SLSS by up to 920% and fracture energy by 15 100% through optimized micro‐nano porous surfaces. RSM identified the optimal anodizing conditions, while ML confirmed sulfuric acid concentration and roughness as dominant predictors of strength.

Where Can Aluminum Go When Batteries Die?

open access: yesAdvanced Science, Volume 13, Issue 7, 3 February 2026.
Battery‐derived aluminum is transformed from contaminated waste into an alloying resource for high‐performance Fe‐based alloys. Through controlled Al content and processing, dual‐phase austenite/ferrite microstructures with TRIP‐like behavior are achieved.

Long‐Term Cycling Stability of Sodium/Sodium Ion Cells Probed by In Situ Solid‐State NMR Spectroscopy

open access: yesBatteries &Supercaps, Volume 9, Issue 2, February 2026.
The suitability of 23Na in situ solid‐state nuclear magnetic resonance (NMR) spectroscopy for long‐term studies of sodium/sodium ion cells is tested. Using silicon carbonitride and hard carbon working electrodes, local structures are analyzed up to the point of capacity degradation and cell failure.
