Realization of Complex‐Shaped Magnetic Nanotubes with 3D Printing and Electrodeposition

open access: yesAdvanced Functional Materials, EarlyView.
Complex‐shaped magnetic nanotubes were fabricated by coating three‐dimensional nanoscaffolds fabricated with focused electron beam induced deposition with a magnetic coating via electrodeposition. X‐ray magnetic microscopy and simulations revealed an azimuthal magnetic configuration within the nanotubes and pinning of domain walls at curved vertices ...

Designing Thermally Compatible Template‐Coating Pairs Toward Dimensionally Stable 3D Porous Carbons with Tunable Density

open access: yesAdvanced Functional Materials, EarlyView.
3D porous carbons with tunable density are crucial for energy storage, separations, and load‐bearing applications; however, their fabrication is often constrained by shrinkage during pyrolysis. This study optimizes and demonstrates the versatility of a template–coating pair strategy, producing materials that largely retain their shape and hierarchical ...

Soft Magnetic Artificial Muscles with High Work Density and Actuation Strain via Dual Cross‐Linking Design

open access: yesAdvanced Functional Materials, EarlyView.
A high‐performance magnetic composite actuator that integrates covalent and reversible physical cross‐links within a stiffness‐tunable polymer matrix embedded with functionalized magnetic particles is presented. The actuator exhibits programmable magnetic responsiveness, a stiffness switching ratio of 1.37 × 103, stretchability up to 1274%, large ...
