Deformation‐Induced Formation of Stray Grains in Additive Manufacturing of Single Crystals

open access: yesAdvanced Science, Volume 13, Issue 25, 4 May 2026.
Stray grain formation severely limits the additive manufacturing of single‐crystal alloys. By integrating in situ synchrotron techniques, ex situ characterization, and multi‐scale multi‐physics modeling, the authors reveal that stray grains originate from dislocations at the solid‐liquid interface, rather than thermal supercooling in conventional ...

Magnetic‐Field‐Driven Precision Fabrication of Multifunctional Microgels for Biomedical Applications

open access: yesAggregate, Volume 7, Issue 5, May 2026.
Superparamagnetic iron oxide nanoparticles embedded in alginate precursors convert magnetic gradients into internal body forces, driving contactless segmentation into uniform microspheres and continuous microfibers without relying on external shear or oil phases.

A Novel Milli‐Scale Magnetic Robot Exploiting Rotation for Controlled Magnetic Particles Release

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 5, May 2026.
Delivering magnetic particles can become a game changer in minimally invasive medicine. To cope with this challenge, a magnetically actuated milli‐scale carrier leveraging rotation to perform on‐demand tunable release of magnetic particles across multiple release events is presented.
