Template‐free tuning of magnetic nanoparticle self‐assemblies in response to external electric and magnetic fields

Responsive Materials, EarlyView.
Electrostatically charged aerosol magnetic nanoparticles enable template‐free self‐assembly of nanochains with tunable length and spacing by adjusting electric‐to‐magnetic field ratios. Lower electric fields favor the self‐assembly of longer and more spatially separated chains, while higher electric fields promote a uniform nanoparticle deposition and ...

Covalent Functionalization of NiFe Layered Double Hydroxides using Tris(Hydroxymethyl)Aminomethane

Small, EarlyView.
Covalent functionalization of NiFe layered double hydroxides with tris(hydroxymethyl)aminomethane enables controlled growth, enhanced structural order, and improved processability. Temporary TRIS anchoring promotes stable water‐based inks and binder‐free electrode fabrication, leading to enhanced oxygen evolution activity and long‐term stability under ...

Domain‐Wall Circulation Gating and Pinning via Compositional Engineering of Cylindrical Nanowires

Small, EarlyView.
Cylindrical magnetic nanowires offer a promising platform for future three‐dimensional spintronic devices. By strategically engineering nanometer‐scale chemical modulations, a novel circulation gate is established to control domain wall propagation.

Sodium‐Based Battery Component Design: Imitating Lithium or Forging New Paths?

Small, EarlyView.
This Perspective elucidates the decisive yet underexplored impact of cation chemistry, Na+ vs. Li+ charge carriers, on the design, selection, and formulation of their corresponding battery systems, addressing common misconceptions and the pitfalls of overreliance on Li+ design principles. Leveraging the unique characteristics of Na+, it comprehensively

Characterization of the Pore Environments in Covalent Organic Frameworks by Dynamic Spin Probe Exchange

Small, EarlyView.
Covalent organic frameworks (COFs) with alkyl or triethylene glycol pore linings are probed with water‐dissolved nitroxide radicals using CW EPR spectroscopy. Adsorption affinity, local polarity, and radical concentration inside the pores are quantified, revealing hydrogen bonding, dipolar, and π‐π interactions that govern guest binding, which ...
