Longitudinal, Multimodal Tracking Reveals Lasting Neurovascular Impact of Individual Microinfarcts

open access: yesAdvanced Science, EarlyView.
Jin et al. investigate the neurovascular impact of microinfarcts, revealing transient neural suppression with minimal cell death and recovery linked to vascular remodeling. Fast‐spiking interneurons exhibit reduced excitability, whereas regular‐spiking neurons showed increased bursting activity. Disruptions in low‐gamma phase locking suggest persistent

Ultrafast Exciton and Spin Dynamics of Monolayer MoSi2N4 Studied by Non‐Degenerate Pump‐Probe Transient Transmission Spectroscopy

open access: yesAdvanced Science, EarlyView.
The resonant energy of the A and B exciton of the new 2D material, monolayer MoSi2N4, is found to be 2.18 and 2.34 eV, respectively, indicating a spin‐splitting energy of ≈160 meV. Complex and diverse exciton dynamics are observed. The work has a profound influence on the future developments of MoSi2N4‐based optoelectronic devices and the synthesis of ...

Electrical Manipulation of Field‐Free Magnetization Switching Driven by Spin‐Orbit Torque in Amorphous Gradient‐Mn3Sn

open access: yesAdvanced Science, EarlyView.
A highly efficient spin current with z‐polarization is achieved in amorphous Mn3Sn with a spontaneous composition gradient, which allows field‐free magnetization switching. Spin current efficiency and magnetization switching polarity are reversibly manipulated by ionic liquid gating, enabling logic functions by pure electrical methods. This work offers

OcuPair, a Novel Photo‐crosslinkable PAMAM Dendrimer‐Hyaluronic Acid Hydrogel Bandage/Bioadhesive for Corneal Injuries and Temporary Corneal Repair

open access: yesAdvanced Science, EarlyView.
A schematic diagram showing the OcuPair adhesive hydrogel formulation loaded into the final delivery device and applied over the full‐thickness corneal wound in an in vivo rabbit model of corneal injury followed by in situ crosslinking to form a transparent hydrogel bandage sealing the wound.

Programmable Metamaterials with Perforated Shell Group Supporting Versatile Information Processing

open access: yesAdvanced Science, EarlyView.
This study proposes a novel mechanical metamaterial with high‐density memory based on multi‐stable perforated shells to realize multi‐layer information encoding, storage, decoding, and reading. The metamaterial can perform more application‐oriented tasks to process information, such as encryption and dynamic behavior regulation, which hopefully enables
