Polymer Network Modified Perovskite for High‐Performance Pure Blue Light‐Emitting Diodes

open access: yesAdvanced Functional Materials, EarlyView.
A polymer network of poly(4‐vinylphenol) (PVPh) is introduced to improve pure blue perovskite light‐emitting diodes. PVPh effectively passivates defects, enhances film morphology, reduces lattice strain, and suppresses ion migration. These effects lead to record device performance, achieving 9.82% external quantum efficiency and stable blue emission at

Multi‐Functional ZnO–Te Heterojunction Devices Enabling Compact Frequency Quadrupler

open access: yesAdvanced Functional Materials, EarlyView.
Wafer‐scale ZnO–Te heterojunction devices featuring tunable double negative differential transconductance (D‐NDT) are demonstrated at ≤ 200°C. Leveraging this unique characteristic, a single‐stage frequency quadrupler is realized, achieving a 64%–75% reduction in device count.

Translational Considerations for Injectable Biomaterials and Bioscaffolds to Repair and Regenerate Brain Tissue

open access: yesAdvanced Healthcare Materials, EarlyView.
The repair and regeneration of brain tissue faces both biological and technical challenges. Injectable bioscaffolds offer new opportunities to stimulate tissue regrowth in the brain by recruiting neural stem cells. Here, the translational issues are reviewed that need to be address to advance this promising new therapeutic approach from the bench to ...
