Ion and Solvent Dynamics in Charged 2D Clay Nanoslits with Unprecedented Ångström‐Precise Slit Height Control

open access: yesAdvanced Functional Materials, EarlyView.
The slit height of fluorohectorite 2D‐nanochannels is tuned with Å‐precision (2.4–250 Å). Slit‐height‐dependent ion and water mobilities are quantified by applying EIS, PFG‐NMR, and SFG‐NMR with MD simulations guiding interpretation. Diffuse properties are investigated with CP‐AFM, MD, and PB.

Coupled Ferroelectric–Photoelectrochemical in Water Reduction Over BiFeO3 Thin Film Heterostructure Modulated by Rare‐Earth Doping

open access: yesAdvanced Functional Materials, EarlyView.
Gd‐doped BFO (BGFO) exhibits a ∼2‐order reduction in leakage current owing to its lowest content of oxygen vacancies. This leads to a ∼2.5‐fold increase in remnant polarization. These improvements in BGFO effectively boost charge separation and transportation, resulting in the greatest incident photon‐to‐current efficiency of 12.9 ± 0.73% and a ∼1.5 ...

3D‐Printed Soft Magnetoactive Origami Actuators

open access: yesAdvanced Functional Materials, EarlyView.
Soft magnetoactive films are 3D‐printed using ink with up to 75 wt.% ferromagnetic particles and dual UV/heat curing, then integrated with various origami structures. The films are flexible, magnetically responsive, and programmable, enabling flexible integration with origami without hindering shape‐changeability.

Multi‐Ion Doping Controlled CEI Formation in Structurally‐Stable High‐Energy Monoclinic‐Phase NASICON Cathodes for Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The graphical abstract illustrates the synthesis pathway, morphological feature, and thermodynamic feasibility of entropy‐engineered NASICON cathodes for sodium‐ion batteries. Abstract Overcoming the energy density limitations of sodium‐ion batteries (NIBs) requires innovative strategies to optimize cathode materials.
