Gel‐Gel Interface Engineering for the Synthesis of Anisotropic Hydrogels with Designable Polymer Orientations

open access: yesAdvanced Materials, EarlyView.
This study reports that when a gel‐gel interface is intentionally introduced into a hydrogel via two‐step polymerization, the polymer networks near the interface spontaneously align perpendicular to it. By employing a photo‐initiator system to spatially control the gel‐gel interface, anisotropic hydrogels with programmable orientations of polymer ...

Terahertz Electronic and Spin Currents in Wafer‐Scale Van der Waals Bi2Se3/WSe2 Heterostructures and Polymorphs

open access: yesAdvanced Materials, EarlyView.
Van der Waals heterostructures offer exciting possibilities for artificial materials with unique optical, electronic, and spintronic properties. However, their use in the terahertz (THz) range is limited due to material constraints. This study demonstrates scalable, large‐area, crystalline 2D heterostructures, combining topological insulators ...

Néel Tensor Torque in Polycrystalline Antiferromagnets

open access: yesAdvanced Materials, EarlyView.
This work introduces a Néel tensor torque based on a rank‐two symmetric tensor capturing spin correlations in a polycrystalline antiferromagnet. It shows the Néel tensor can be shaped and reshaped through the spin‐orbit torque (SOT) technique, enabling field‐free SOT switching with a specific polarity of the adjacent ferromagnet. This discovery opens a
